Re: LIbvirt Python Snapshot -Domain Crashing
Martin,
Actually domain doesn't crash, but it state got changed to pause, till the
snapshot action got complete.
Its a time consuming process.
so here is my requirement.
I want to take snapshot of a Running Domain on every 3 hours,( at a later
point of time It should be possible to revert to the actual domain state
when I took the snapshot), I'm using libvirt APIs python bindings,
there

Re: snapshot anomaly
I had the same problem yesterday. I found the solution from this article
https://kashyapc.fedorapeople.org/virt/lc-2012/snapshots-handout.html.
According to the article it deletes the tracking metadata by libvirt.
You can physically remove the snapshot now that there is no tracking stream
data by libvirt

virsh snapshot-create --print-xml seems to ignore most arguments
Hi,
I am wondering if the --print-xml option is working correctly. The
output for two snapshot-create commands are the same, even though the
first one includes additional options (no-metadata and atomic).
I want to use the generated XML to create a snapshot via a perl script,
and Sys::Virt only seems to support snapshots using a XML description
of the arguments.

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)

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

proper way to snapshot
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>

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
