I am fairly new to KVM (used Xen for awhile) and I am having a small problem with snapshots. I am using the VM Manager plugin for all my KVM needs. Every time I save a snapshot, it disappears on reboot. I am also using a the new .qcow2 format.

 

Am i doing something wrong with snapshots? I do not want them to be deleted (unless I myself delete them)

 

EDIT: Just looked at the XML data, I can see my 3 snapshots description in the <metadata> tag. But they are not listed in the plugin main page.

We have had a lot of problems with snapshots in general because there are different mechanisms for XML tagging to support this either in-file our with a separate backing store.  In the first instance of our merger with the VM manager plugin, we will not have snapshot support built into the webGui.  That said, if you want to read up on how to edit XML to define backing stores for snap-shotting purposes, the XML can be found here:  http://libvirt.org/formatdomain.html#elementsDisks

 

We plan to implement snapshot support in the future.

Ill take a look through and see what I can do. I am not to familiar with KVM, so this seems like a good time to get my hands dirty!

 

In the mean time, I have been powering off the virtual machine, and duplicating the .qcow2 file. That way, I can rollback if needed. Not the most space effective manner, but works none-the-less.

 

Thanks
