[libvirt-users] libvirt support for sheepdog file system
by Narendra Prasad Madanapalli 23 Sep '10

23 Sep '10

Hi Everyone, I am planning to extend libvirt to support sheepdog for qemu/kvm and found that storage code is placed in src/storage. Storing files in sheepdog is independent of file system and we just need to specify vm-name on qemu command ine. Here are the following comands used for creating and running a VM using qemu qemu-img create sheepdog:MyImage001 25G qemu-system-x86_64 sheepdog:MyImage001 I would appreciate if any one provide pointers on incorporating sheepdog functionality to libvirt. Thanks, Narendra.

Re: [libvirt-users] access VMX config on esxi with virsh
by frank dirks 23 Sep '10

Hi, you are right - the problem is specific to only that one vmx file - for other virtual machines dumpxml is working, as i found out. i am using esxi 4.1.0 and virsh 0.8.4. the machine was created using vsphere client, and was cloned and renamed afterwards - maybe that was the problem ... regards, frank > > Hm, that's strange.

[libvirt-users] correction
by Glynn D. Reynolds 22 Sep '10

22 Sep '10

I have corrected the error! Error: Sep 18 13:53:46 gdrenterprise libvirtd: 13:53:46.116: error : virInterfaceDefParseMtu:141 : XML description for interface mtu value is improper is not well formed or invalid To correct this error you will have to remove or correct the entry of virtual IP's added to /etc/sysconfig/network-scripts/ by the virtual application. Theory! I suspect that if you add the network interface with application that have non root privileges or you have configured /etc/access.conf. In additional to running selinix, root could be the one that may have the authority to add the network interface configuration. -- Glynn D. Reynolds <glynnreynolds123(a)gmail.com> GDRENTERPRISE

Hi! I am new to libvirt. I would like to know where would you make the change to correct this error. I am not sure to add an entry in /etc/libvirt/network/default.xml or not. Could you provide ne with a current link to the documentation that will provide me information to correct this information.

[libvirt-users] Is it possible to live migrate guest OS'es between different versions of kvm/qemu-kvm with libvirt?
by Nils Cant 22 Sep '10

22 Sep '10

Hi, I currently have a couple of Debian KVM servers with all a different version of kvm or qemu-kvm. I can live migrate a guest OS from one server to the other just fine, as long as the version of qemu-kvm is the same. However, when I try to migrate a guest to a server running a newer (or older) version of qemu-kvm, I run into problems. I think this is because the xml configuration differs slightly between version. For example, if I try to migrate from a server running qemu-kvm 0.11.0 to one running qemu-kvm 0.12.4, I get the following error: virt01:~# virsh migrate --live testserver qemu+ssh://192.168.1.7/system error: internal error unable to reserve PCI address 0:0:3 When migrating from kvm 85 to qemu-kvm 0.11.0: virt02:~# virsh migrate --live testserver qemu+ssh://192.168.1.2/system error: Unknown failure Migrating one from 0.12.4 to 0.11.0 just completely breaks libvirt, forcing me to kill -9 libvirtd and the kvm instance, etc. I believe this is caused in part because different versions of qemu-kvm need different xml configurations. To run my testserver on 0.12.4 for example, I need to delete the lines with the PCI id's, just to be able to start it. So, is there a way to make this work? Perhaps tell libvirt to not send the config file when doing a live migrate, and use the xml in /etc/libvirt/qemu instead somehow? Thanks in advance, Nils

[libvirt-users] Query regarding Xen_ComputerSystem
by CB, Anantha Padmanabhan 22 Sep '10

22 Sep '10

Hi, Libvirt provides classes such as Xen_ComputerSystem, Xen_Processor etc., in order to build applications using libvirt-api which can interact with the Xen Hypervisor. I would like to know what are the corresponding classes for the KVM hypervisor, so that I can use libvirt-cim to communicate with the hypervisor. Would it be Kvm_ComputerSystem or Qemu_Computersystem? Any help in this regard would be of great help. Thanking you. Regards Ananth
