  • How to place a virtual machine in DMZ?

    - by Giordano
    I have an Ubuntu 12.04 server running few virtual machines with KVM. I would like to expose some of these virtual machines on the internet, to make it possible for customers to test the products we're developing and make available other products for demo purposes. One of the server NICs is configured with a public IP. However before exposing anything on the web I would like to be sure that if one of the virtual machines get compromised, the attacker doesn't reach the rest of the hosts. What I would like to do is to put these virtual machines into a DMZ. These are the steps I'm planning to do: Create a tap interface in the virtualization host (let's say tap1) Create a bridge using tap1 and give it an IP in a subnet separate from the other hosts. Let's say 10.0.0.1 Attach the DMZ virtual machines to the bridge and configure their IP statically (10.0.0.2, 10.0.0.3, etc...) Using UFW, forbid any traffic from 10.0.0.0/24 to any of the internal hosts, allow the traffic from the internal hosts towards 10.0.0.0/24 and expose the virtual machines on the web using port forwarding. Do you think this setup is safe? Can you suggest any improvement or a better/safer approach? Thanks in advance!

  • Running Mixed Physical and Virtual Exalogic Elastic Cloud Software Versions in an Exalogic Rack is now Supported

    - by csoto
    Although it was not supported on older versions, now as of EECS 2.0.6, an Exalogic rack can be configured in a mixed-mode: half virtual and half physical Linux: Flexibility to have physical and virtual environments on same rack. For example, production on physical and test/dev on virtual. Exalogic Control manages the virtual compute nodes on the rack. Physical compute nodes are managed manually (including PKeys). Option to change full physical to hybrid and hybrid to full virtual rack. User has an option to choose either the top or bottom nodes for physical or virtual deployment. For further information about how the compute nodes can be split up on the rack (into bottom or top half) to run either Oracle Virtual Server (OVS "hypervisor") or Oracle Linux, please take a look at MOS Note 1536945.1. Note: Solaris is not yet supported in the mixed configuration.

  • Debug website on host from virtual machine

    - by Luchaguate
    I have a Windows 7 machine hosting a Windows 7 virtual machine. I am developing a web application using visual studio 2010 on my host machine. I want to run the application in debug mode and access my localhost server from a browser on the virtual machine. (The purpose of this is to be able to debug an application that uses Windows Authentication using different users without having to log off and on for different users on my host machine...) I am using a bridged connection for the virtual machine. I googled how to solve this problem and most of the threads that I found said that if I was using a bridged connection, I could access the server on the host machine by just entering the IP address of my host machine into the url in the browser of the virtual machine. I have tried some different urls using the IP but none of them have worked. As an example, suppose I run my web application in visual studio on my host machine and its url is http://localhost:62789/MyPage.aspx Assume also that I ran ipconfig in CommandPrompt on my host machine and found out that the IP address for my host machine is xxx.xxx.xxx.x. What url should I enter on the virtual machine to access my web application? Thanks in advance.

  • Ping "replies" from same computer with 'Destination host unreachable' (no route to other computer)

  • Moving windows-2003 hdd into virtual machine - with HDD shrink

    - by jm666
    Before you vote to close as exact duplicate, please read the full question. I was already read: Can I make a virtual machine out of a Windows XP physical machine? Disk2vhd,convert my PC to Hyper-V Virtual Machine Creating a Windows Virtual PC image from a Physical machine physical machine to virtual machine and place into VirtualBox BSOD trying to migrate Windows XP from a physical to a virtual machine http://en.wikipedia.org/wiki/Physical-to-Virtual and all other similiar questions here and several external sites too Unfortunately, don't find answer for my problem. I have an physical machine with 500GB HDD, on what is installed old Windows-2003 server with one server application. The application is like the windows itself, too old, no support for it today, haven't installation media and so on.. ;( On the HDD it is used only approx. 100MB (maybe less when will delete all unnecessary files). Want convert the the machine into the VirtualBox, and the VirtualBox should run on the same machine. Is possible to do this with the next steps? I can attach another HDD (via USB or internally) Boot an live Linux from CD, mount HDDs Run "something" on the Linux (the above wikipedia article have many pointer for the SW) for the conversion and store the image on the USB HDD - unfortunately, many of tools uses some specialty what exists in Windows-XP and above. No informations about Windows-2003 server, so what is an working solution for Windows-2003? try boot the virtual image with VirtualBox when it will run ok, remove the old installation, install Linux on the old 500GB hdd, copy the image and run.. The above should works (i hope), but the problems: i currently have only 320GB external USB hdd. (ofc, i can remove it from a box and enter it as internal HDD too) so, for the conversion I looking for the on the fly HDD shrink, so while moving the physical 500GB HDD need shrink it into smaller HDD - as i told above, only 100MB is used Exists something for this? (free) - or the only way is buying and larger 1TB hdd and using it for the conversion? Another question are: is anybody have real experience with windows-2003 conversion into VirtualBox? Looking for an answer from someone who really doing it and can figure out real pitfalls. (googling can do myself). exists here better approach for the solution?

  • "Integrated" VMs (As opposed to "Sandboxed")

    - by sabof
    It is common for virtual machines to be sandboxes, their interaction with the host OS being limited to the absolutely necessary. Are there any projects that would try to integrate VMs (specifically Virtual Box) with their host OS (specifically Ubuntu on Windows host, but I'd be curious of other combinations as well)? Things like opening all files with a certain extension in either the host or the guest. Possibly other nice things I haven't thought of.

  • Accessing guests on virtual network when connected to host via PPTP

    - by Viktor Elofsson
    I'm setting up a development machine which runs Ubuntu 12.04 and KVM for virtualization. I have a guest running Ubuntu 12.04 which can be accessed from the host via its IP address which is assigned by libvirt. The guest can also access the internet, no problem there. However, now I want to setup PPTP so I can connect to the host (from my workstation running Windows 7) and directly access guests without relying on SSH port forwarding. I can connect from my W7-machine to the host (PPTP), but I cannot access any virtual machines (which are accessable from the host directly). Relevant configuration files cat /etc/network/interfaces auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address x.x.x.x broadcast x.x.x.x netmask x.x.x.x gateway x.x.x.x # default route to access subnet up route add -net x.x.x.x netmask x.x.x.x gw x.x.x.x eth0 virsh net-edit default <network> <name>default</name> <uuid>xxxxxxxx-72ce-3c20-af0f-d3a010f1bef0</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0' /> <mac address='52:54:00:xx:xx:xx'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> <host mac='52:54:00:yy:yy:yy' name='web1' ip='192.168.122.11' /> </dhcp> </ip> </network> cat /etc/pptpd.conf (commented lines removed) # TAG: option # Specifies the location of the PPP options file. # By default PPP looks in '/etc/ppp/options' # option /etc/ppp/pptpd-options # TAG: logwtmp # Use wtmp(5) to record client connections and disconnections. # logwtmp #(Recommended) localip 192.168.122.1 remoteip 192.168.122.234-238,192.168.122.245 cat /etc/ppp/chap-secrets* # Secrets for authentication using CHAP # client server secret IP addresses xxxxx * yyyyyyyyyy 192.168.122.100 I get the correct IP address when connecting my W7-machine, but when I try to ping the virtual machine at 192.168.122.11 I get Reply from 192.168.122.1: Destination port unreachable. It's probably something trivial I'm missing but I can't for the life of me figure out what it is. So I'm turning to you, serverfault.

  • How can I run the same Linux Installation on my hardware and in a virtual machine?

    - by LithMaster
    I've started some development that requires Linux (I'm currently on Ubuntu, but I may switch to Debian), but I still use Windows 7 for my day-to-day computing. I have already tried a dual-boot setup, but I've found that it is too cumbersome to switch between Linux and Windows. I'm wondering if it's possible to setup an installation of Linux (again, Ubuntu or Debian) on a partition of my hard drive that I can also run from Windows in a virtualized environment.

  • Create netbook recovery image without DVD burner (virtual burner?)

    - by Dan
    I have a new Acer Aspire One which is asking to create a recovery DVD. It doesn't have a built in burner, and I don't have a USB burner. However I do have a large USB hard drive. Is there some way to get the recovery software to "burn" an image file instead of a real DVD? I know you can download a Linux recovery image, but the netbook comes with XP. I plan to install Linux on it but I'd like an XP recovery image just in case.

  • How Can I assign an IP address to my virtual Windows Server, so that I can start using it almost as a VPS?

    - by Nelson Symonds
    We are a small office set up with two PC's out of which one of my PCs runs 24hrs. Its almost equivalent to a small server, but right now we're in need of a server which is why I am planning to keep my machine as well as a server into a single PC. I've used VMware Workstation to create a powerful Windows Server 2008 within my PC and I want to attach it to my Network Switch through the same PC where I am hosting it. I want to use it almost like a physical server with an IP address and everything so that I can connect from one Pc to the Server directly or my applications can connect to Server straight with the IP address. How should I do this? Step by step instructions would be appreciated. Thanks in Advance, Best regards Nelson

  • Postfix to deliver mail to a virtual address mailbox

    - by Chloe
    Postfix version 2.6.6, Dovecot Version 2.0.9 I want to setup Postfix + Dovecot. Dovecot seems to be working. I can authenticate. However, the mailbox is empty! Nothing will get delivered! I followed many tutorials on Postfix + Dovecot but they seem to want to complicate things by using Dovecot LDA or MySQL. I just want it to be very simple and having Postfix deliver to the virtual mail boxes are fine. I don't need MySQL either. I already set up a custom password file that Dovecot uses for authentication and I can login to POP3 with SSL. I can see from the logs that Postfix is delivering to the system user accounts (the catch-all), instead of the virtual users that I set up in Dovecot. The SMTP + SSL authentication seems to work also. I can also see from the logs that Dovecot is checking the correct virtual mail folder. I just need to figure out how to get Postfix to deliver to the virtual mail boxes. I have the following which I believe are relevant. Let me know what other settings you need to see: alias_maps = hash:/etc/aliases mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = xxx.com myhostname = mail.xxx.com mynetworks = 99.99.99.99, 99.99.99.99 myorigin = $mydomain relay_domains = $mydestination, xxx.com, domain2.net, domain3.com sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = reject_non_fqdn_sender reject_non_fqdn_recipient reject_unknown_recipient_domain permit_sasl_authenticated check_relay_domains smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_sender_restrictions = check_sender_mx_access cidr:/etc/postfix/bogus_mx reject_invalid_hostname reject_unknown_sender_domain reject_non_fqdn_sender virtual_mailbox_base = /var/spool/vmail virtual_mailbox_domains = xxx.com, domain2.net, domain3.com virtual_minimum_uid = 444 Postfix master.cf: submission inet n - - - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_sasl_security_options=noanonymous -o smtpd_sasl_local_domain=$myhostname -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_login_maps=hash:/etc/postfix/virtual -o smtpd_sender_restrictions=reject_sender_login_mismatch -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject Dovecot related: mail_location = maildir:~/Maildir passdb { args = /etc/dovecot/users.conf driver = passwd-file } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 user = postfix } } The virtual mail user: vmail:x:444:99:virtual mail users:/var/spool/vmail:/sbin/nologin Here is the /var/log/maillog when I try to send something to myself: Oct 25 22:10:05 308321 postfix/smtpd[2200]: connect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:05 308321 postfix/smtpd[2200]: D224BD4753: client=user-999.cable.mindspring.com[99.99.99.99], sasl_method=LOGIN, [email protected] Oct 25 22:10:06 308321 postfix/cleanup[2207]: D224BD4753: message-id=<7DC3C163CFFC483AB6226F8D3D9969D2@dumbopc> Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: from=<[email protected]>, size=1385, nrcpt=1 (queue active) Oct 25 22:10:06 308321 postfix/smtpd[2200]: disconnect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:06 308321 postfix/local[2208]: D224BD4753: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=1.1, delays=0.53/0.02/0/0.51, dsn=2.0.0, status=sent (delivered to mailbox) Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: removed

  • Internet Explorer cannot display page from apache with single SSL virtual host

    - by P.scheit
    I have a question that has come up somehow in different questions but I still can't find the solution, yet. My problem is that I'm hosting a site on apache 2.4 on debian with SSL and Internet Explorer 7 on windows xp shows Internet Explorer cannot display the webpage I have only ONE virtual host that uses ssl, but DIFFERENT virtual hosts that use http.

In fakt: I only have one ssl certificate for the domain. And I only want to run ONE virtual host with ssl. So I just want to use the one ip for the ssl virtual host. But still (after rebooting / restarting / testing) internet explorer will still not show the page. When I intepret the apachectl -S as well, I already have only one SSL host and this should response to the initial SSH handshake, shouldn't it? What is wrong in this setup? Thank you so much Philipp

  • How do I make a Windows virtual machine replicate to another datacenter/cloud?

    - by zippy
    We have a Windows 2008 VM running IIS and SQL Server Express (it's an all-in-one web application). We need to have another copy at our secondary datacenter site. What is the best way to do this? It doesn't have to be running all the time but it has to have almost the latest copy of the current VM. I took a look at VMWare Fault Tolerance and after the heart attack at the price I starting looking for another solution. If need be I wouldn't mind copying it over to a cloud VM provider, if I can find one that lets me copy my own VMs up and start them up without any conversion process.

  • How can I run a Virtual Machine in Windows 8 Developer Preview?

    - by Marc Gravell
    Since having issues installing Ubuntu side-by-side with Windows 8, I thought I'd try running Ubuntu in a VM instead. However, VMWare player has no love for Windows 8 yet (invalid VM86 or something similar), and AFAIK the promised hypervisor options are not currently available for playing with. So: Are there any VM hosts that do work in Windows 8 Developer Preview at this point? (specifically for running Ubuntu) Alternatively, does Wubi work on Windows 8? It seems not; from Wubi: An error occurred: 'WindowsBackend' object has no attribute 'iso_path'

  • Mac OS X Lion (10.7.3) Virtual Machine?

    - by Ben Hooper
    I have been looking into this for a while and have attempted quite a few "solutions" (hackintosh boot images, universal unlockers, etc) before I gave in and asked for help. I know this is extremely difficult to accomplish, especially with an AMD CPU, but it has been done and it can't hurt to ask. Question Does anyone know of any way to actually get Mac OS X Lion (10.7.3) to boot in VMware Workstation 8.0.2? I know that Mac OS X is heavily dependant on hardware configuration, so I will post my PC's hardware below, if it helps. As far as I know it's only reliant on the CPU, but I will post it all just in case.

As soon as I attach the interface to my machine a new entry is added to the routing policy and local routing table: sudo ip rule show 0: from all lookup local 32765: from 10.1.1.190 lookup 10003 32766: from all lookup main 32767: from all lookup default $ sudo ip route show table local broadcast 10.1.1.0 dev eth3 proto kernel scope link src 10.1.1.190 local 10.1.1.190 dev eth3 proto kernel scope host src 10.1.1.190 broadcast 10.1.1.255 dev eth3 proto kernel scope link src 10.1.1.190 broadcast 10.1.3.0 dev eth0 proto kernel scope link src 10.1.3.12 local 10.1.3.12 dev eth0 proto kernel scope host src 10.1.3.12 broadcast 10.1.3.255 dev eth0 proto kernel scope link src 10.1.3.12 broadcast 127.0.0.0 dev lo proto kernel scope link src 127.0.0.1 local 127.0.0.0/8 dev lo proto kernel scope host src 127.0.0.1 local 127.0.0.1 dev lo proto kernel scope host src 127.0.0.1 broadcast 127.255.255.255 dev lo proto kernel scope link src 127.0.0.1 I can send traffic to this ENI directly from a host that can have the same IP as the host the ENI is attached to. This is where the problem starts. I ran tcpdump on the port in question and saw multiple SYNs going to the ENI with src '10.1.3.12' and destination '10.1.1.190' but didn't see even a single ACK. In my understanding if ACKs were being sent from the ENI they'd have destination as 10.1.3.12 i.e. the same as the local machine's IP and such packets will now be routed as local packets matching local routing policy: local 10.1.3.12 dev eth0 proto kernel scope host src 10.1.3.12 I'd like to send all the packets originating from 10.1.1.190 (my ENI) to go back on the same interface i.e. eth3 in this case. Contents of the nee table 10003 are: $ sudo ip route show table 10003 default via 10.1.1.1 dev eth3 I think I can do the following: I don't know if its possible but probably decrease the priority of local table so the packets match the table 10003. Use iptables to mangle these packets and update the local table route to include the mark information But I'm not sure if these are the right approaches.

  • Is there a way to get a 10000x10000 virtual resolution desktop?

    - by pingo
    I have a java applet map viewer and I'd like to plot out the map it displays. To do that I need to open it in a high enough resolution to avoid too much stitching. Is there any possible way I could get a desktop with such high resolution? So far I've been able to use panning 2560x1920 by booting windows 7 in VmWare Player. Would it be possible to get it higher? Maybe this would be doable on Linux? The whole thing can be laggy as hell as long as it will render my screenshot...

  • Checking if Intel VT-x acceleration is enabled from inside a VMware virtual machine?

    - by user269950
    My (Fortune 500) company just rolled out new VMs and everyone is complaining they are dog slow. Is there any way I could verify, from inside a VM, whether Intel virtualization (VT-x) acceleration has been properly enabled? The processor claims to be a Xeon E7-2830 but the experience has been more like a first-gen Atom. I'd ask IT directly but I get the impression they're unlikely to respond to any suggestion that they are, in fact, drooling imbeciles.

  • Webcast: Best Practices for Speeding Virtual Infrastructure Deployment with Oracle VM

    - by Honglin Su
    We announced Oracle VM Blade Cluster Reference Configuration last month, see the blog. The new Oracle VM blade cluster reference configuration can help reduce the time to deploy virtual infrastructure by up to 98 percent when compared to multi-vendor configurations. Customers and partners have shown lots of interests. Join Oracle's experts to learn the best practices for speeding virtual infrastructure deployment with Oracle VM, register the webcast (1/25/2011) here.   Virtualization has already been widely accepted as a means to increase IT flexibility and help IT services align better with changing business needs. The flexibility of a virtualized IT infrastructure enables new applications to be rapidly deployed, capacity to be easily scaled, and IT resources to be quickly redirected. The net result is that IT can bring greater value to the business, making virtualization an obvious win from a business perspective. However, building a virtualized infrastructure typically requires assembling and integrating multiple components (e.g. servers, storage, network, virtualization, and operating systems). This infrastructure must be deployed and tested before applications can even be installed. It can take weeks or months to plan, architect, configure, troubleshoot, and deploy a virtualized infrastructure. The process is not only time-consuming, but also error-prone, making it hard to achieve a timely and profitable return on investment.  Oracle is the only vendor that can offer a fully integrated virtualization infrastructure with all of the necessary hardware and software components. The Oracle VM blade cluster reference configuration is a single-vendor solution that addresses every layer of the virtualization stack with Oracle hardware and software components, see the figure below. It enables quick and easy deployment of the virtualized infrastructure using components that have been tested together and are all supported together by Oracle.

  • OTN Virtual Developer Day for WebLogic Server and WebLogic Developer Broadcasts

    - by mike.lehmann
    To further move the new year of 2011 underway for WebLogic Server, quite a series of hands on technical online events and broadcasts are about to get underway from the WebLogic team. The first is Virtual Developer Day: Oracle WebLogic Server which is an online event that combines hands on labs with WebLogic Server through a series of Virtual Box images. This event will cover things like the new Java EE 6 capabilities one can use on WebLogic Server, using Maven and Hudson with WebLogic Server, developing with Web services on WebLogic Server and even upgrading from Oracle Application Server. Very technical, very hands on. And its global - multiple geographies covered.  Nice! James Bayer has put out a full agenda for this on his blog as well as links on how to register. The second is a 5 week long weekly technical broadcast under the umbrella of Accelerate Your Development with Oracle WebLogic Suite walking through topics like working with JPA, designing distributed caching strategies with WebLogic Server, advanced JMS topics and UI topics like JQuery as well restful Web services with Jersey and JAX-RS.  Again in James' blog the full agenda is available to check out if it is interesting for you to attend including a brief video introduction outlining in a bit more detail exactly what will be covered. Hopefully between these two events and the release of WebLogic Server 10.3.4 earlier in January, we are kicking off 2011 in a good fashion.  Looking forward to sharing more as we go forward in 2011.

  • VirtualBox : increase hard disk size of the virtual machine

    - by wim
    I have run out of space on my WinXP virtual machine, which I only gave 10 GB space for when I created it. Is there an easy way to increase it to, say, 20 GB? I can't see any obvious option in VirtualBox settings. edit: the suggestion below gives this error wim@wim-ubuntu:/media/data/winxp_vm$ VBoxManage modifyhd wim.vdi --resize 20000 VBoxManage: error: Cannot register the hard disk '/media/data/winxp_vm/wim.vdi' {46284957-2c09-4e70-8a49-bfbe0f7f681d} because a hard disk '/home/wim/VirtualBox VMs/winxp_vm/wim.vdi' with UUID {46284957-2c09-4e70-8a49-bfbe0f7f681d} already exists VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBox, interface IVirtualBox, callee nsISupports Context: "OpenMedium(Bstr(pszFilenameOrUuid).raw(), enmDevType, AccessMode_ReadWrite, fForceNewUuidOnOpen, pMedium.asOutParam())" at line 210 of file VBoxManageDisk.cpp edit2: removing the .vdi from VirtualBox before calling VBoxManage command, then adding it back in, was successful. But now I can't boot the virtual machine, I get this worrying screen: By the way, it says FATAL: Could not read from the boot medium! System halted. edit3: The vdi must be reattached to the VM after VBoxManage command. Further, the partition will need to be resized from WITHIN windows, because you will have this empty space: I was able to resize the partition easily using a bit of freeware called EASEUS Partition Master 9.1.0 Home Edition.
