  • Virtual Disk Service Loader has stopped working

    - by Leigh Riffel
    We have several relatively recent (less than 1 week) installations of Windows Server 2008 R2 Enterprise that are getting this error whenever we open Disk Management. The application name is vdsldr.exe and the Problem Event Name is BEX64. The windows firewall was turned off and the service disabled. The Virtual Disk service was started (identical results when it is stopped). The computers are virtual machines running on VSphere, so that could be part of the problem. The strange thing is that Disk Manager worked fine when the VMs were first created.

  • Hyper-V server 2012 nic teaming setup and virtual switch configuration

    - by Calvin
    I have a server with 2 nics. I installed Hyper-v 2012 server (not windows server 2012, no gui) I am trying to set up load balancing. I have both nics in the same switch currently in trunk mode and no native vlan. I use the new-netlbfoteam command to create a team with both nics, I can then "set-netlbfoteamnic "Nic Team" -vlanid 4" so that its available to me with a DHCP or static address but as soon as I try to create a virtual switch it becomes unresponsive. My guess is that is due to it removing the vlan tagging I setup. if I add-netlbfoteamnic and set it for vlan 4, then set the IP I can ping it from my management computer but I just get an error "an error occurred while attempting to connect to server "xxxxxx" Check that the Virtual Machine Management service is running and that you are authorized to connect to the server."

  • NTPD seems to delete all network interfaces

    - by Aurelin
    We have a couple of virtual interfaces configured on eth0 on a CentOS, and every now and then, they went down seemingly out of the blue. Now after going through the log files, I found out that apparently ntpd deletes all eth0 interfaces, and that dhclient automatically brings eth0 back up. The virtual interfaces, however, stay down which causes several of our websites to be inaccessible. Can someone explain to me why ntpd deletes interfaces? Can / should that be turned off, or can / should I configure dhclient to bring the virtual interfaces back up automatically, too? EDIT// The log files that I should've posted : Nov 12 13:10:28 raptor dhclient[20048]: DHCPREQUEST on eth0 to 255.255.255.255 port 67 (xid=0x6a825e97) Nov 12 13:10:42 raptor dhclient[20048]: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8 (xid=0x24554092) Nov 12 13:10:42 raptor dhclient[20048]: DHCPOFFER from 96.126.108.78 Nov 12 13:10:42 raptor dhclient[20048]: DHCPREQUEST on eth0 to 255.255.255.255 port 67 (xid=0x24554092) Nov 12 13:10:42 raptor dhclient[20048]: DHCPACK from 96.126.108.78 (xid=0x24554092) Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #31 eth0, 50.116.50.97#123, interface stats: received=3255, sent=3256, dropped=0, active_time=1559394 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #32 eth0:0, 50.116.53.56#123, interface stats: received=3, sent=0, dropped=0, active_time=1559391 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #33 eth0:1, 66.175.211.192#123, interface stats: received=2, sent=0, dropped=0, active_time=1559389 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #34 eth0:2, 50.116.53.95#123, interface stats: received=3, sent=0, dropped=0, active_time=1559387 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #35 eth0:3, 97.107.132.32#123, interface stats: received=2, sent=0, dropped=0, active_time=1559385 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #36 eth0:4, 50.116.56.201#123, interface stats: received=2, sent=0, dropped=0, active_time=1559383 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #37 eth0:5, 66.175.212.121#123, interface stats: received=2, sent=0, dropped=0, active_time=1559381 secs Nov 12 13:10:42 raptor ntpd[2109]: Deleting interface #38 eth0:6, 66.175.215.137#123, interface stats: received=2, sent=0, dropped=0, active_time=1559379 secs Nov 12 13:10:44 raptor NET[1573]: /sbin/dhclient-script : updated /etc/resolv.conf Nov 12 13:10:44 raptor dhclient[20048]: bound to 50.116.50.97 -- renewal in 32692 seconds.

  • setting up a basic mod_proxy virtual host

    - by SevenProxies
    I'm trying to set up a basic virtual host to proxy all requests to test.local to a WEBrick server I have running on 127.0.0.1:8080 while keeping all requests to localhost going to my static files in /var/www. I'm running Ubuntu 10.04. I have libapache2-mod-proxy-html installed and I have the module enabled with a2enmod proxy. I also have my virtual host enabled. However, whenever I go to test.local I always get a cryptic 500 server error and all my logs are telling me is: [Thu Mar 03 01:43:10 2011] [warn] proxy: No protocol handler was valid for the URL /. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule. Here's my virtual host: <VirtualHost test.local:80> LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so ServerAdmin webmaster@localhost ServerName test.local ProxyPreserveHost On # prevents this folder from being proxied ProxyPass /static !

  • Virtual Machine Manager 2012 CPU Average

    - by Grant
    What exactly is the CPU Average field in VMM 2012 showing me? I'm running Server 2008 R2 with VMM 2012. My server has 2x16 core CPUs installed. An example virtual machine has 4 virtual processors, and shows 20% CPU usage. Is that: 20% of the entire system's available CPU power? 20% of 4 of the 32 core's CPU power? 20% of one core's CPU? (in which case it could go as high as 400%) Something else entirely? How can I tell how much of the entire system's CPU power is being used (all 32 cores)? Edit: Well, I can tell for sure it's not 20% of the entire system's CPU power - since the entire server's CPU averages add up to well over 100% right now.

  • Dynamips Virtual Router not pinging external host after bridging

    - by maiky
    I have setup a virtual router image with dynamips and setup bridging between tap0 interface of the virtual router and eth0 and br0 with commands [root@cisco_host]# brctl addbr br0 [root@cisco_host]# ifconfig br0 up [root@cisco_host]# ifconfig eth1 0.0.0.0 [root@cisco_host]# brctl addif br0 eth1 [root@cisco_host]# ifconfig br0 192.168.0.100 netmask 255.255.255.0 up In dynagen configuration I have: f0/0 = NIO_tap:tap0 So, [root@cisco_host]# brctl addif br0 tap0 [root@cisco_host]# ifconfig tap0 up router(config)#int fa0/0 router(config-if)#ip address 192.168.0.101 255.255.255.0 router(config-if)#no shutdown After the configuration above I was expecting that from inside the router I could ping an external machine with IP 192.168.0.1 Actually from the host I can ping the external host 192.168.0.1 as well as 192.168.0.100 and 192.168.0.101. So what am I missing here? tap0 is bridged with br0 and in turn with eth1. So why the router is not pingable from 192.168.0.1 and vice-versa??

  • "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.

  • Managing two domains in one virtual server [on hold]

    - by Buddhika Ariyaratne
    I have a virtual server with Windows Server 2012 on which I need to run two applications for two separate customers. Both applications run on GlassFish in port 8080. The applications run on http://localhost:8080/roseth and http://localhost:8080/ruhunu My virtual server provider has given three IP addresses. How can a I assign one address for each application. For example, if a user type www.ruhunu.org, an arbitrary URL , I want to direct to http://localhost:8080/ruhunu and www.roseth.org to http://localhost:8080/roseth.

  • hyper-v multiple virtual machines with >2TB volumes from one raid

    - by wurlog
    I have a server with two Raids. Raid 0: 2x 1TB Raid 6: 8x 2TB The first raid I used for the hyper-v installation itself. The virtual machines should use the Raid 6, but how can I config it? I need at least one file server with the most of the disc space (maybe a second). But every vhd has a maximum of 2 TB and I can't use the volume directly because other virtual machines have to have access the Raid6. What do I do?

  • restricting access only through domains on nginx on virtual hosts

    - by Mo J. Mughrabi
    I have finished setting up nginx for virtual hosting, this is how my config files look like server { listen 80; server_name domain.com; access_log /home/domain.com/prod_webapp/logs/access.domain.com.log; error_log /home/domain.com/prod_webapp/logs/error.domain.com.log; location /static { root /home/domain.com/prod_webapp/mocorner/ph/; } location / { try_files $uri @uwsgi; } location @uwsgi { include uwsgi_params; uwsgi_pass unix:/tmp/domain_uwsgi.sock; }} on the same machine, I have domain1.com and domain2.com, each when i access I get its content which is great. My problem is that when i try to access the user using the IP address i get one of the sites in the virtual hosts too.. Although i disabled the default (removed the symbolic link) from sites-enabled folder but still not solved it for me. any suggestions?

  • Sizing a Virtual Server

    - by vdubs
    I would like to replace four aging physical servers with one virtual server. What is the best way to insure the VM server is sized correctly? The requirements of the apps that will be running on the four servers are APPLICATION SERVERS - QTY 3 - These will run the application layer for the web server, Business Objects Business Intelligence app, and various other small client server apps. The three most heavy hitting apps each have the following server requirements. So, if I bought three physical servers, this would be the requirements for each of them Processor - Dual 2.83 GHZ (or faster) Ram - 4 GB Raid 5 - 50-100GB usable space NIC - 1 GB Web Server - this will run one asp.net e-business app that will talk to our dedicated SQL server and the three app servers above. The E-Business software has these requirements for the web server Processor - Quad 2.83 GHZ (or faster) Ram - 8 GB Raid 5 - 50-100GB usable space NIC - 1 GB What is the best tool to determine what I need from a hardware standpoing in a virtual server? I am planning on using VMWare.

  • One bigger Virtual Machine in Cloud

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). 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 e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

  • Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

    - by Mike Z
    I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

  • Migrated Virtual Machine Shows Up in Both Datastores

    - by Backstage
    Hi, We're using Vsphere client 4.0.0 Build 208111 with Virtual Center Server same version and same build. I have one vm with only one disk that is shown on 2 different datastores. If I look through VMs and Templates I see only 1 vm. If I look through Datastores screen, I see it in datastore-002 and datastore-003. If I go to settings of the virtual machine on datastore-002 and check the disk, I see the path as datastore-003. How can I fix this ?

  • Virtual fiber channel HBA in Solaris

    - by Phil
    We are trying to set up some virtual Fibre Channel HBA's in Solaris. This seems to be possible with NPIV. Creating NPIV's in a Solaris global zone works fine, but passing that NPIV to a zone didn't work at all. We tried to pass the NPIV as following: # zonecfg -z zone1 'info' zonename: studentz1 [...] device: match: /devices/pci@0,0/pci8086,25f9@6/pci8086,350c@0,3/pci1077,140@4/fp@1,0:devctl allow-partition not specified allow-raw-io not specified Wat we want to do is, set up an environment for SAN exercises. We don't have a physical host per student, so we try to virtualise that in some way (Solaris zones or VMware). It should be possible to display the WWN of the virtual HBA and mount the storage presented by the disk subsystem. Any ideas to pass the NPIV to a solaris zone or to virtualise this with vmware?

    - by user23950
    I have installed virtual box for ubuntu 9.10. I installed a windows xp inside it. And I don't know why it does not make the webcam available for the yahoo messenger installed in xp. When I click on the device in the interface of virtual box. I can see the webcam but it is grayed out. And I don't know why. It is also not available when I use wine to execute yahoo messenger. And I know that it is working because I can see its working when I use skype for ubuntu. Any suggestions?Its an acer aspire laptop, the webcam is built in.

  • 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?

  • Deploy virtual PC based on snapshot using Hyper-V

    - by user27786
    I have a server with Hyper-V configured, it is easy to create a new virtual machine using the management tools, but it can take some time. I often see those hosts that say "We can have your server ready in 5 seconds". And I wonder how do they manage this? I would also like to deploy a full functional clean server in 5 seconds. So how is this done? Is it by first installing a clean server, then take a snapshot of that for later to deploy a new server based on that snapshot? I tried doing this, but I did not find any where to install a new virtual machine based on the snapshot. Anyone got any thoughts to share on this?

  • Connect to virtual host computer from within virtualbox

    - by Nicky De Maeyer
    I'm currently developing on an ubuntu karmic. For this I've installed lampp with a virtual host on apache so http://myproject/ is mapped to my project's root directory. Now to test the website in IE I've installed an XP machine on a virtualBox OSE. Ive managed to get the virtual host working on the XP by adding its to the hostfile, like this: 255.255.255.255 myproject where 255.255.255.255 is the ip adress of the host computer (my ubuntu). Now every day when I come to work and plug in my computer to the network, my IP has changed. so When i boot the XP I have to change the IP in the hostfile to my new IP. Is there any way where I can set the ip to somthing the XP will recognise as the host machine? I've tried replacing the IP in the hostfile by the host computer name, but that does not seem to work... This would make my like a bit easier :)

Also, I want to set up 2 virtual Servers with 2008 R2 standart one with SQL Server and the other with Team Foundation. What i need is: Being able to access from inside the private phisical network, to Remote Desktops on each of the Virtual and the phisical Servers Had Access from the outside, using a router and port Forwarding, to the TFS server and the IIS server (one is virtualized, the other is phisical) This is it, but note that I only have one Phisical Nic. How do I configure this to work. When i set up the hyper-v role, on the wizard something like it showed up but I don't remmember what i choose, and right now, I cannot access none of the servers from remote desktop, not even from the phisical private network. Can anybody point me, what can i do? Thanks in advance (sorry 4 my english, i'm a spanish talker and my english isn't that good)

  • Virtual NIC on VM couldn't ping externally after Vmotion

    - by ToreTrygg
    Today I vmotioned 5 MS SQL 2005 servers over to a new DRS Cluster. All SQL servers use the "Production_LAN" network and a single virtual NIC of type "VMXNET 3". The first 4 SQL VM (Windows 2003 Standard or Enterprise x32 bit) vmotioned over without a hitch. The last SQL VM I vmotioned (Windows 2003 Standard x64 bit R2) vmotioned over without error, but I upon completion, I could no longer ping the VM. I went into the VM and could not even ping the gateway, however I could ping the loopback. This SQL server is extremely busy in comparison with the previous 4 VM's. I restarted the server and it came back up with the virtual nic working just fine. The build of both servers (vmotioner and vmotionee) is ESX 4.0.0 175625 - So, pre-update 1. Should I suspect the network switch/VM for possibly not updating the mac table on the switch? Anybody else ever have this issue or know what may have caused it? Thank you!

  • How to configure cookieless virtual host in Apache2?

    - by xzyfer
    We run over a hundred web applications (growing daily) on a LAMP stack using Apache2 on Ubuntu 10.04. We've would like all requests to static content to be cookieless. We host applications on many different domains, a majority of which as SaSS applications. Many of the domains host instances of the applications on sub domains, ie. myapp.example.com, myapp2.example.com myapp.otherexample.com etc.. At the moment all static content is server relative to the (sub)domain requesting it. As far as I understand the process, I would need to setup a new domain, eg. staticexample.com. In this case is special configuration in the virtual host for this domain required to ensure no cookies are served? Also, would it be possible to instead use static.example.com? In this case what configurations would I need in my virtual host for this subdomain to ensure no cookies are served?

  • How to set robots.txt globally in nginx for all virtual hosts

    - by anup
    I am trying to set robots.txt for all virtual hosts under nginx http server. I was able to do it in Apache by putting the following in main httpd.conf: <Location "/robots.txt"> SetHandler None </Location> Alias /robots.txt /var/www/html/robots.txt I tried doing something similar with nginx by adding the lines given below (a) within nginx.conf and (b) as include conf.d/robots.conf location ^~ /robots.txt { alias /var/www/html/robots.txt; } I have tried with '=' and even put it in one of the virtual host to test it. Nothing seemed to work. What am I missing here? Is there another way to achieve this?
