hi, i am a bit confused on how to start an inactive domain using the python bindings, any help would be appreciated. (inactive as in the domain was created with?virConnect.defineXML sometime in the past) looks like i have to use virDomain.create, however virDomain.create needs a defined domain xmldesc as a parameter and i am not sure on how to get that i guess if?virConnect.create was happening right after?virConnect.defineXML i could get the return value of?virConnect.defineXML and pass that onto virDomain.create. however, since t...

how do i print the features of a domain from functions that return a domain object? for instance mydomain =?virdomain=libvirt.virConnect.lookupByID(conn,domainid) so mydomain is?virDomainPtr, which is?typedef virDomain * virDomainPtr i am not sure on how to print the domain object features in python, such as name, disk size, etc

Hi, I am using virStorageVolGetInfo to get the volume size virStorageVol.download to download a normal file for VDSM project. I want to add support for block devices as well, I was able to see the size via virDomainBlockInfo and download via virDomain.blockPeek which is works fine for both file and block device. 1. Can I depend on virDomainBlockInfo for non block devices? 2. Does the virDomainBlockInfo return the correct physical size for normal file? 3. Performance wise do we have a difference between virSto...

Can somebody knows how to enable virtio-scsi-data-plane in libvirt for specific domain? I know that i need to replace "-device virtio-scsi-pci" with "-object iothread,id=io1 -device virtio-scsi-pci,iothread=io1" in qemu, but how can i do this in libvirt? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru

Yes, thanks! Does in near feature libvirt devs integrate this ability to domain format? As i understand all qemu stable features supported by libvirt. And data plane for virtio-blk is stable for some time.... -- Vasiliy Tolstov, e-mail: v.tolst...

Hi, I wanted to know if there is any Python API exposed for libvirt using which I can attach a libvirt volume to a libvirt domain/VM. I intend to do something similar to the `attach-disk` command of virsh using python. -- *Regards,* *Varsha Verma* *Final Year Undergraduate* *Department of Electrical Engineering* *IIT-BHU, Varanasi*

Hi all, I am trying to add vcpupin in the guest xml file. I am working with openstack and the code I have is python bound. I investigated through the code and found that the elemets in xml file are set in get_guest_config function. Now the thing is I am not able to set vcpupin element. I mean I tried guest.cputune_vcpupin but it's not working. Help me out, please! Thanks.   ~Peeyush Gupta

Hi Libvirt, Does libvirt-python currently support adding a base path to virDomain.blockPull()? In particular, I would like to have the behavior of the following virsh command (from https://kashyapc.wordpress.com/2013/01/22/live-backup-with-external-disk-snapshots-and-libvirts-blockpull/) in libvirt-python: [image: image.png] Thanks! Sincerely, Roger Jin -------------- next p...
