• how to connect virtual box os and local machine

  - by Nrew

  This question is in connection to this question asked by a user before: http://superuser.com/questions/73470/virtualbox-vdi-file-to-vmware On how to convert vdi to vmdk or vmx using vmware converter. How do I connect the windows xp that is in virtual box to the local computer (windows 7) in a network. Because I got this error while I tried following this instruction: Give the IP address, username and password of the remote machine that you would like to convert and then hit next I got this error in vmware converter: Unable to connect the specified host 10.0.2.15 which is the ip address of the xp machine inside virtual box. It also said that there is a network configuration problem. And when I inputted the ip address from whatismyip.com which should be the same as the ip address on local machine. I didn't get the previous error but I got another one, it said that: insufficient permissions to connect to "ip address" What solution can you suggest for this problem?

• One bigger Virtual Machine distributed across many OpenStack nodes [duplicate]

  - by flyer

  This question already has an answer here: Can a virtualized machine have the CPU and RAM resources of multiple underlying physical machines? 2 answers I just setup virtual machines on one hardware with Vagrant. I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM with OS | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- More details: In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes. If we imagine this Nodes(Novas) are placed on a separate machines (e.g. every has 4 cores) can I run one Virtual Machine across many OpenStack Nodes? Is it possible to aggregate the computation power of OpenStack in one virtual distributed operating system?

• Windows Server 2012 guest machine no internet or LAN

  - by Boycey

  I have a windows server 2012 with hyper-v added as a feature. I have created a server 2012 and a windows 8 guest machines. The windows 8 machine has internet connectivity and can successfully be added to our AD domain. I can log in to the domain on this guest machine with an AD account. However the server 2012 guest machine cannot be joined to the domain and does not have internet connectivity. Strangely enough (to me!). Is there any special settings/config that I should be doing/have missed?!

• FTP Issue when connecting to a debian machine from windows

  - by erin c

  I have a .net application which copies bunch of files to a specific FTP folder on a debian machine on periodical basis, ftp folder has 755 mod, owner of the directory is the ftp username that I authenticate in .net application. So far I tested this application with bunch of debian boxes, my initial attempts generally fail with following message if I try it with a debian machine that I haven't tried it before: "remote server returned an error 550 File unavailable" When I see this error, I log onto another debian machine on my network, and I try FTP'ing the debian box that returns the error message from command line. I generally "put" a very small file to the folder in question, right after that windows application starts copying files successfully via FTP. It is as if my command line ftp operation fixes the problem and makes debian compatible with my .net application. I checked permissions before and after the problem, it doesn't look like what I did changed anything, I am at loss understanding why this problem occurs and why it is fixed with my silly hack. Can anybody tell me where to look at next to fix this extremely annoying issue?

• How to backup a remote VPS machine?

  - by morpheous

  I am considering opting for a VPS solution, with the server running Ubuntu server. I am pretty new to this, and I need to come up with a backup policy for my server data. Initial data is likely to be about 80Mb, and I expect the data to grow at approximately 5Mb to 10 Mb a day. Can anyone recommend: A backup/restore policy (best practises for a small startup) Which tools to use for backup? Another thing that is not clear to me is - where are the files backed up to normally (in the case of remote servers). If the files are backed up to the same machine (or even to another machine but with the same host), there is potentially, a single point of failure). How do people normally backup their server data, and is the probability of machine meltdown or the host company server farm "catching fire" so remote as not to be worth worrying about - especially for a small (read one man) startup like me?

• access VPN machine macosx same subnet

  - by matheszabi

  I would like to access the office machine, which has a fixed IP, and is available only in its local LAN. Let say 192.168.1.100. I have a VPN with username/password connection and I am trying to access the office machine from another location, i.e., another LAN, which has the same subnet: 192.168.1.50. I am using MacOSX 10.8. I have checked the "send all trafic over VPN connection, but I think it looks like it doesn't care and is searching in Local. I do not have admin privileges and can't request to make changes to the network settings in both LANs. Is there any way to connect to the desired remote machine?

• How to copy only VM changes in VMware to another physical machine

  - by Paul

  How can I use VMware Workstation to copy only changes to a VM to another physical machine, rather than recopying the entire VM every time? Can I just copy the snapshot files, if the second physical machine starts from a pristine copy of the VM? Would it be best to create a linked clone against the original VM, and then copy the linked clone directory each time? Does that even work? (I'm assuming I'll have to change the path in the VM's metadata file, since the paths will be different. I'm assuming I can't clone a linked clone w/o cloning the base.) Background: I and another developer with VMware Workstation are using VM's for systems development. I have to work from a home desktop. Transporting a multi-gigabyte VM either direction takes several hours at best. Downloading it is easiest, but that takes an hour to get it on a DMZ machine for download and then many hours to actually download.

• Auto log off windows machine after certain number of minutes

  - by Marty Heath

  I have three machines on my network, two are windows xp and one is windows 7. i would like to have all three machines log a user off if they are on for more than 60 minutes. And I would like this to be applied to the machine not on a per user basis, because I do not want this policy to apply to those users on any other machine. I have installed winexit.scr on one of the machines but the problem is that I cannot change the default value of 10 minutes for the screensaver because that is controlled through group policy, and I cannot seem to find where to change that through group policy on a per machine basis NOT on a per user basis. If I have left out any details I apologize please let me know anything that is needed

  - by Luc

  Hello, I have several machines on my lan. On of them is running 2 web sites, first_web_site and second_web_site (each one in a dedicated NameVirtualHost). Another machine is running another site third_web_site. I would like to be able to access each one, within internet, with the url: first_web_site.domain.tld second_web_site.domain.tld third_web_site.domain.tld knowing that 2 sites are on the same machine.

• Server 2008 locks me out when not using the machine for 10 minutes after installing SP2

  - by Daniel Magliola

  I have recently installed Service Pack 2 on my Windows Server 2008 machine (which I use actively for development, and i'm always logged on to). Now, after this installation, when I don't use the machine for some time (let's say, 10 minutes), it locks itself so I have to press Ctrl+Alt+Del and log back in. I have already checked the Screen Saver settings, and it's "None", as it always has been. I also looked into power settings and everything looks right (20 mins to turn off monitor, and i haven't found any settings regarding locking me in there). Do you have any idea what I can do so that it won't lock me out after not using the machine for a while? Thanks! Daniel

• VMware Fusion / New Machine / verify VMs?

  - by drewk

  I just got a 15" MacBook Pro with 8GB RAM, 2.66 i7 and 500GB SSD. Very sweet and fast! My old machine was 2.66 Core 2 Duo. I used Migration Assistant to migrate my old MBP to the new. When I started VMware to run Windows and Ubuntu I got the message first This VM has been moved or copied to a new machine. Did you move or copy it? I answered Copied. Then I got the message this CPU is a different configuration than the machine that created the VM. You may get unpredictable results. I answered Open Anyway. Windows XP, Windows 7, and Ubuntu all seem to work OK, but how can I verify? Is there some form of test harness for a VM? I have had a VM degrade and become unusable with very catastrophic data loss (on Parallels...), so I am a bit paranoid. Thanks,

• Remote desktop to my KVM virtual machine

  - by user6

  I've got a dedicated server running Debian 6. I've set up a windows 7 virtual machine using KVM. Now I'm trying to get Remote desktop working. I'm guessing i have to do some port forwarding. The virtual machine is in a NAT. Remote desktop is already set up on it (another virtual machine can connect). I've tried using the iptables and countless of virsh commands of which I'm not even sure what they did. Anyone knows how to get this working?

• How can I share files from my Windows 7 machine to my friend's Ubuntu machine?

  - by ProfKaos

  I run a Windows 7 Pro SP1 laptop as my home machine, and my housemate runs an Ubuntu 12.04.1.05 desktop. We share a WLAN. I would like to make certain locations and files available for him to read and maybe write. How can I go about this? Bearing in mind I have very little recent experience with modern Linux, and Ubuntu in particular. My first idea is to share a Windows folder with my Ubuntu VM under VMWare Player, then his Ubuntu machine can connect to my Unbuntu VM, and the two can use whatever magic Ubuntu uses to achieve file sharing. This requires my Ubuntu VM to be always running though, and that may not always be possible. I have also heard that Samba may have a feature to help here, but I know nothing about that. How can I share my Windows files with my mate's Ubuntu machine, preferably with a 1 to 1 connection, i.e. rather not using shim VM's

  - by Conner Stephen McCabe

  I was just wondering if anyone knew how to/or knew of a good guide to setting up mac Time Machine backup server on a fedora 17 machine. I recently ran into an issue with my HDD and lost all of my data, so I don't want it to ever happen again, as it was quite traumatising, haha! I just want to be able to back all of my data up on my fedora machine from my mac, at scheduled times when I connect to my home network. If anyone could help, it would be fantastic, I searched around on google, but all of the ones I found were for older distros. Thanks guys!

• MSSQL 2008 is claiming the firewall is blocking ports even from local machine

  - by Mercurybullet

  I was just hoping to step through a couple queries to see how the temp tables are interacting and I'm getting this message. The windows firewall on this machine is currently blocking remote debugging. Remote debugging requires that the debugging be allowed to receive information from the network.Remote debugging also requires DCOM (TCP port 135) and IPSEC (UDP 4500/UDP500) be unblocked Even when I walked over to the actual machine and tried running the debugger, I'm still getting the same message. Am I missing something or does the debugger try to run remotely even from the local machine? Since this was meant to be just a quick check, I don't need instructions on how to open up the firewall, just hoping there is a way to run the debugger locally instead.

• Windows Virtual Machine ping reply fails the first few times

  - by user28471

  I am running a windows Web Server 2008 virtual machine. When I try to ping it from another windows machine the ping reply comes straight back with 100% success. But when I try to ping it from one of the Linux boxes, the ping reply fails with partial or 100% loss the first couple of time and succeeds the third time onwards. I know it is quite strange but can any one think anything that could be causing it. Could anything in the Windows Domain Security or Firewall be "taking time" to allow responding to the ping request? In fact even the firewall is turned off on the virtual machine.

• Is virtual machine slower than the underlying physical machine?

  - by Michal Illich

  This question is quite general, but most specifically I'm interested in knowing if virtual machine running Ubuntu Enterprise Cloud will be any slower than the same physical machine without any virtualization. How much (1%, 5%, 10%)? Did anyone measure performance difference of web server or db server (virtual VS physical)? If it depends on configuration, let's imagine two quad core processors, 12 GB of memory and a bunch of SSD disks, running 64-bit ubuntu enterprise server. On top of that, just 1 virtual machine allowed to use all resources available.

• Multi-machine backup solutions

  - by Paul

  I have a growing number of PCs and laptops in my home that need a backup solution. My question is 2 fold: Most commercial backup vendors appear to license by the machine, are there any products that give a license that can be used on all your machines, without a per machine cost? An alternative is to have a centrally controlled back up strategy controlled from a single PC with an attached hard drive that can back up other machines on the network. What backup software is suitable for this approach? Will this software be windows/Linux interoperable? I've searched for duplicate questions but don't see anything that addresses the multi machine/cost issue. OSs in network will be Windows (XP, Vista, 7) and Linux variants. Not pattern to when machines will be switched on.

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• How can you import a root certificate to a machine level store in Windows 7

  - by ReluctantAdmin01

  I have a service (Running as local system) that uses an SSL connection. Currently this connection fails because the remote host used a private CA to sign it's certificate. For previous operating systems, I used to use the certificate manager to import the CA cert into the local machine's Trusted Root certificates store. Though I can do the steps with a windows 7 machine, it seems after a reboot that the imported certificates are gone. Here are the steps I'm doing in Windows 7: Open mmc Add Certificates Snap-in for Local Machine Navigate to Third-Party Root Certification Authorities/Certificates Import Root CA Cert. The certificate seems to work fine, using internet explorer or the service to test the SSL connection works, but after a reboot it seems like the change is reverted.

• Internet connection fails in Ubuntu on VirtualBox when virtual machine is created from "Import appli

  - by Sanoj

  I have installed Ubuntu Server 9.10 in a virtual machine in VirtualBox, then I made a cope/clone and exported it with "Export appliance" so I can create many cloned virtual machines. But when I try to import an appliance, everthing seams to be fine with the Ubuntu except that it can't connect to Internet and doesn't get an IP-address. The machine is used in Bridged mode. And it doesn't help to change to NAT-mode either. The machine that I cloned seams to work fine, and get an IP address. How to fix this? Where am I doing wrong?

• unable to ping machine on WLAN

  - by N.M.

  I've started accepting remote desktop connections on one of my machines. If i connect the machine to my router using an Ethernet cable i am able to ping it and connect to it remotely (using RDP). However, if i connect the machine using wireless network i am unable to ping it (or access it using RDP). Although i can live with connecting that machine using an Ethernet cable i just wanted to know the reason why it doesn't work using wireless. Is the router not able to forward packets to that host if its connected using wireless? If yes, any solutions?
