similar to: Snapshot without volumes temporarily

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>

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

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

Hey When I want to take a snapshot for a Domain by using virDomainSnapshotCreateXML. The Error as below happen: libvir: QEMU error : Requested operation is not valid: Disk '/var/lib/libvirt/images/fedora-qcow.qcow2' does not support snapshotting The snapshot Configuration is : <domainsnapshot> <description>Snapshot of OS install and updates</description>

Hi， I used 'virsh snapshot-create' create an encrypted external snapshot, when I try to use 'qemu-img check' top file, found no entrance to pass backing-file's secret-id 1、Version centos-release-8.2-2.2004.0.1.el8.x86_64 libvirt.x86_64 6.0.0-17.el8 qemu-kvm.x86_64

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

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

Hello. What it the difference in external snapshot configuration with and without <domainsnapshot> ? What is the difference between vda and vdb in the following example?

Hi guys, I had to move to the new laptop week ago and I screw migration of my virtual machines. I recovered my virtual machines on the new laptop (virsh define) using the backed up xml files, but I am missing any file with metadata about snapshots. The original storage is cleaned so I cannot take these files anymore. Using qemu-info I can see my snapshots inside the qcow images, but libvirt

Hi There , I have KVM VM with 4 qcow2 disks and 2 raw disks . when I try to take full system snapshot by excluding raw disks . it is give below error . can you help me how to fix this ?. or is it possible to take full system snapshot in this case .?. When I change XMl as internal snapshots for raw disks . It throws a message snapshot are not supported on war disks .

Hello, I would like to ask what I am doing  wrong and what is the best approach to resolve this situation: First of all I start virtual machine by virDomainCreateXML. In my application I use libvncclient library that sends mouse events to this running domain. I had some troubles with coordinates of mouse cursor but all problem was solved when I added <input type='tablet'

Let's say I have a vm, vm1, which has a lv as its hard drive: <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source file='/dev/mapper/kvmtest_vm1_rootvg'/> <target dev='vda' bus='virtio'/> <address type='pci'

Hi guys, When performing live merge, in few cases, we see the following exception: Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 736, in wrapper return f(*a, **kw) File "/usr/share/vdsm/virt/vm.py", line 5278, in run self.tryPivot() File "/usr/share/vdsm/virt/vm.py", line 5247, in tryPivot ret =

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
