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.defi...

Hello all, I find this curious behavior that libvirt will automatically insert a USB controller and a memballoon virtio driver into the domain's XML, when defineXML is called. IOW, the original XML did not have these 2 devices but they are present right after defineXML is called. Why should libvirt add a USB controller? DETAILS: Here is a little Python snippet to show that behavior: import libvirt conn = libvirt.open('qemu:///system') xml_list = open...

Hi all, I have the following issue, and I hope someone know a way to handle it. I need to grammatically need to create/install a guest OS using the libvirt API. Currently what I do: 1. create a xml with the vm configuration (this will include a path to the iso image) 2. connection.defineXML(<my_config>) 3. vm = connection.lookupByName(<domain_name>) 4. vm.create() This will create a new guest and boot the iso to install the OS. But after installation, when I restart, It again boots from the cdrom. So obviously I need remove the cdrom somehow. I could edit the xml and m...

...API I get the "no boot disk found" message when starting the vm. When importing the VM through the libvirtAPI, I use the same xml description virsh outputs (dumpxml) after initially doing the import. xml - the description I got using virsh xmldump <domain name> xmlDesx = xml conn.defineXML(xmlDesc) One other important aspect is I am using a directory storage pool to store all my volumes (.img files). When I use virsh to import the vm, the storage pool recognizes the new volume (the .img file I converted from the .vmdk file). But when I use the libvirtAPI, it does not. So my guess i...

hi, when creating a domain using libvirt python api, how would i tell libvirt to use a unique serial port number for domains? in the?libvirt.virConnect.defineXML(conn,domainxml) call when i create the domainxml object, i need to ensure that the part below has a unique # for target port <serial type='pty'> ? <target port='0'/> </serial> <console type='pty'> ? <target type='serial' port='0'/&...

I am trying to change a domain configuration from a python script. More specific, I want to edit the VNC settings. You can't do this using the libvirt API so you have to edit the domain configuration: Fo exmple, to disable VNC for a domain 'test1': vmXml = vm.XMLDesc(0) root = ET.fromstring(vmXml) devices = root.find('./devices') graphics = devices.find('graphics')

hi, i am trying to create a domain using libvirt 0.9.4 python api and i can't find any information on how to use the libvirt python api with linux logical volumes http://libvirt.org/guide/html-single/#Application_Development_Guide-Device_Config-Disks is TBD i figured out that i need to use defineXML to create a domain, however for the disk part in the xml, i am not sure if i need to create the LVM first, or just specify the LVM path and libvirt will create the lvm for me and stick the domain on the lvm ? ? <disk type='block' device='disk'> ? ? ? <driver name='qemu...
