From what i read in the net is that libvirt supports snapshoting of raw files when the guest is shutdown and the file of the snapshot becomes a qcow2. Right ? I try to avoid converting my raw file to a qcow2 file. I can shutdown the guest for a certain time, that's no problem. I don't need a live snapshot. But how can i revert to my previous state if my configuration changes go wrong ? Can i do this with snapshot-revert or do i have to edit the xml file and point
I have several guests running with raw files, which is sufficent for me. Now i'd like to snapshot one guest because i make heavy configuration changes on it. the hd again to the origin raw file ? What i found in the net wasn't complete clear.
Thanks.
Hi, i found that: https://dustymabe.com/2015/01/11/qemu-img-backing-files-a-poor-mans-snapshot... I tried it and it seemed to work, although my root fs was checked after the commit, anything else seemed to work. What do you think of this procedure ? Bernd Helmholtz Zentrum München
