Hello I am having a libvirt installation on kvm, ubuntu 10.04. A few months ago, I setup a cloud on the hypervisors which was functioning really cool. But from last two-three days I am getting following error on using function snapshotListNames in python. >>> snapshots=dom.snapshotListNames(0) libvir: Remote error : unknown procedure: 187 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/dist-packages/libvirt.py", line 890, in snapshotListNames if ret is None: raise libvirtError ('virDomainSnapshotListNames() failed', dom=self) libvirt.libvirtError: unknown procedure: 187 Any ideas so as what could be causing the error? -- Abhishek Webpage <http://abhishekgupta92.info/> !!!

[libvirt-users] Associating a statefile with an image
by sethuraman subbiah 05 Jul '11

05 Jul '11

Hi , I am trying to perform offline migration (i.e) Create an incremental image using the qcow format, transfer the vm memory state to a state fie.Use the image and statefile together as a template. Now create a new vm using the template. I can successfully do it using the following commands : Save phase : stop migrate "exec:gzip -c > STATEFILE.gz" qemu-img qemu-img create -b BASE_img -f qcow2 INCRE_img Restore phase : qemu-kvm -m 1024 -hda INCRE_img -incoming "exec: gzip -c -d STATEFILE.gz" And it works fine. But I am not able to find the vm with virt-manager or other libvirt based tools. If I use : virsh save <dom_id> STATEFILE I can restore using "virsh restore STATEFILE" but I want to associate this with the incremental image that I created, but I dont know how. I think it saves the existing vm's xml file along with the STATEFILE, thus I am not able to change the disk image to the incremental image. Thus , 1. Either I should find a way to make vms created using qemu-kvm appear in libvirt-based tools. OR 2. Find a way to associate the virsh save STATEFILE with a incremental image. Any help or hint with respect to these will be very helpful. I am try to do cloning with minimal cost. This takes only 25 seconds ( to create STATEFILE) and creating incremental image is instantatenous . But I want to use the vm monitoring code based on libvirt. And it makes life difficult. Thanks for your help. - Regards, Sethuraman Subbiah Graduate Student - NC state University M.S in Computer Science

*Writting myVirt* ------------------------------ Dear all, I'm new in libvirt. I would be glad if you help me. I want to write a program for controlling all libvirt servers named "MYVIRT". The libvirtd works as fallow: { CLIENT } ---------------------> { SERVER A } | | ------------------------------> { SERVER B } Now, I want to place MYVIRT between client and libvirtd servers. By calling a command, MYVIRT should execute the command for all servers. { CLIENT } | | { MYVIRT } ---------------------> { SERVER A } | | ------------------------------> { SERVER B } The client softwares for libvirtd are virsh and virt-manager. Now I want them to connect to MYVIRT and look it as a libvirtd server. Would you please guide me for connecting to MYVIRT through virsh and execute a command on all servers?

[libvirt-users] Unable to boot from a vdi image
by yeswanth swami 02 Jul '11

02 Jul '11

Hi, I am not able to boot a vdi image on virtualbox using libvirt .It keeps showing me "Bootable medium not found". I have tried booting it manually with virtualbox GUI and it boots without any problem. May there is some problem with my libvirt domain XML . I also realized on some investigation that it is not detecting the vdi image file as a hard disk (when i am booting from a live cd) A part of my libvirt domain XML is here: <os> <type>hvm</type> <boot dev='hd'/> </os> ------------------------------ <devices> <disk type='file' device='disk'> <source file='disk.vdi'/> <target dev='hdd' bus='ide'/> </disk> </devices> Thanks for replying -- Cheers, Yeswanth
