hi, i am getting this error below when i try to create a storage volume: ? ? libvirt.virStoragePool.CreateXML(storagepoolobject,xmldesc,0) AttributeError: class virStoragePool has no attribute 'CreateXML' my code is: xmldesc="xml description of storage volume which i got from sudo virsh vol-dumpxml" #get a storage pool object to use in creating a volume storagepoolobject=libvirt.virConnect.storagePoolLookupByNam...

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 the domain was created sometime in the past, i am not sure on how...

Hi all, I am trying to figure out if you can store the definition of a directory storage pool in a custom location. This is how I create the storage pool: xmlDesc = """ <pool type='dir'> <name>guest_images_storage_pool</name> <uuid>8c79f996-cb2a-d24d-9822-ac7547ab2d01</uuid> <capacity unit='bytes'>4306780815</capacity> <allocation unit='bytes'>237457858</allocation&...

...on II from a backup of XML descriptions. That's not quite an automated/fluent process, and the idea of doubling hypervisors into a HA cluster just for that matter is clearly overkill to me. Are you, by chance, aware of an OpenSource libvirt-based solution that is able to keep track of each VM xmldesc, starting lost guests as transient domains on another hypervisor upon failure of the original hypervisor ?

Hi all, I am using libvirt to manage VM on my system; after creating a VM (default no NICs are present in the configuration) you can add any number of interfaces to it (as long as they exist on the host). To do that, I edit the configuration xlm: vmXml = self.domain.XMLDesc() root = ET.fromstring(vmXml) devices = root.find('./devices') intf = ET.SubElement(devices,'interface') intf.set('type', 'bridge') src = ET.SubElement(intf,'source') src.set('bridge', bIntf) mo...

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') devices.remove(graphics) xml = ET.tostring(root) with open('path_to/test1.xml', 'w') as f: f.write(xml) not the problem is with the test1.xml. Even though the domain...

...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 is that b...

Let's say I have some iptables rules defined to restrict guest traffic. If I restart the hosts firewall 'service iptables restart', all the guest-specific rules get blown away. Is there a way to reapply all the guest firewall rules, without restarting each individual guest? It looks like if I edit a nwfilter with `virsh nwfilter-edit` it goes and reapplies the rules to all the
