similar to: error: argument unsupported: unable to handle disk requests in snapshot

I have an oVirt engine node that currently runs the system on a qcow2 based virtual disk, and an NFS export volume on RAW. I'd like to take a snapshot before a somewhat risky upgrade of oVirt and can't with the raw image attached. Looking at the documentation for the snapshot XML, I created this XML file for the snapshot <domainsnapshot> <name>20120802</name>

Hey John, Hehe, I got the right guy then. Very nice! And very good ideas but I may need more time to reread and try them out later tonight. I'm fully in agreement about providing more details. Can't be accurate in a diagnosis if there isn't much data to go on. This pool option is new to me. Please tell me more on it. Can't find it in the file below but maybe it's

Can you provide some more details with respect to which libvirt version you have installed. I know I've made changes in this space in more recent versions (not the most recent). I'm no root_squash expert, but I was the last to change things in the space so that

Hello, I am working on a script to automatically create live snapshots of running VMs using qemu-kvm 1.4.0 and libvirt 1.0.2. If a VM has multiple disks, I'd like to back them up individually with separate calls to snapshot-create-as, so I can more easily manage the disk images. The code I have now is essentially as follows: virsh snapshot-create-as --domain "vmname" --name

Cheers, I'm working on Ubuntu server 11.10 32 bit with libvirt 0.9.2 and qemu-kvm 0.14.1. I have a user oneadmin:oneadmin who also belongs to kvm and libvirtd groups. I have set qemu.conf and libvirtd.conf with user/group oneadmin. I have disk.0 and deployment.0 files owned by oneadmin. My system does not support hardware virtualization so I don't have /dev/kvm. I'm able to

Hi all, I'm using ZFS on Linux block volumes as my VM storage and want to do live migrations between hypervisors. If I create ZFS snapshot of used volume on source host, send it do destination host (zfs send/recv) and then run live migration with VIR_MIGRATE_NON_SHARED_DISK flag, the migration works OK. But this procedure copies the whole disk twice which is a huge downside. The best

Hi, I'm using libvirt(1.0.0) with python, for managing virtual machines.. but while taking multiple snapshot domain is crashing... Snapshot XML ------------------------- <domainsnapshot> <name>snp1</name> <creationTime></creationTime> <description>Description</description> <state></state> <domain>

Hi, dear friend. My guest has two disks, vda and vdb. both are qcow2 local file. When guest running state. I want to take the vda snapshot of guest(just vda, no include vdb). but I met libvirt do snapshot for all disks of guest. About methods for follow: 1、 ``` bash virsh snapshot-create-as 8x0lbzvS --name sys_disk3 --disk-only --diskspec "vda,snapshot=external" ``` ``` result

Hi Martin, in the meantime, I've found a solution which I consider at least acceptable: 1. create zfs snapshot of domain disk (/dev/zstore/test-volume) 2. save original XML domain definition 3. create snapshot in libvirt like this: virsh snapshot-create --xmlfile snap.xml --disk-only --no-metadata test-domain snap.xml: <domainsnapshot> <disks> <disk

I've created a very basic snapshot XML file, to allow for a description of the snapshot. However when running the virsh command, it doesn't like the formatting. # virsh snapshot-create proxy_0 /vmstore/proxy_0/proxy_0_ss.xml error: XML description for failed to parse snapshot xml document is not well formed or invalid This are the XML file contents... # cat proxy_0_ss.xml

Hi Libvirt, Does libvirt-python currently support the creation of external snapshots? I ran domain.snapshotCreateXML(xml) where xml is <domainsnapshot> <name>snap1</name> <description>Snapshot of OS install and updates</description> <disks> <disk name='vda'> <source

Hi, While there are a few howtos floating around, what is the standard way to snapshot guests? I went through and converted from raw to pre allocated meta data qcow2 images for this purpose. Some howtos suggest to do an xml snapshot file as so; <domainsnapshot> <name>UbuntuServer_10.10-16032011</name> <description>Snapshot of OS install and

Hey When I want to take a snapshot for a Domain by using virDomainSnapshotCreateXML.
