Re: Live migration with non-shared ZFS volume
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

Live migration with non-shared ZFS volume
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

Snapshot system: really confusing.
Greetings, I am developing a platform for test and debug use. The typical scenario I want to realize is the following: I run a .qcow2 image via QEMU-KVM, the running OS is not relevant. I want to take several snapshots of both Disk and RAM status; same file, separate files doesn't matter. I just need a way to have consistent information about them (better with XML description) and the data

Recover snapshots from qcow images
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

Excluding RAW disk from 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>

XML file format for snapshot-create
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

Some howtos suggest to do an xml snapshot file as so; <domainsnapshot> <name>UbuntuServer_10.10-16032011</name> <description>Snapshot of OS install and

Snapshot without volumes temporarily
Hello, I want to do a snapshot which the VM has volumes. But I want to skip the volume check when I do the snapshot. (Which means I want to do a snapshot without detaching the volume) So I try to write a snapshot XML refer by http://libvirt.org/formatsnapshot.html as following: vda is my VM basic disk (qcow2) vdb is a volume (raw) ================ t1.xml =============== <domainsnapshot>
