[libvirt-users] snapshot of a raw file - how to revert ?

Hi, i have the following system: pc59093:~ # cat /etc/os-release NAME="SLES" VERSION="11.4" VERSION_ID="11.4" PRETTY_NAME="SUSE Linux Enterprise Server 11 SP4" ID="sles" ANSI_COLOR="0;32" CPE_NAME="cpe:/o:suse:sles:11:4" pc59093:~ # uname -a Linux pc59093 3.0.101-84-default #1 SMP Tue Oct 18 10:32:51 UTC 2016 (15251d6) x86_64 x86_64 x86_64 GNU/Linux pc59093:~ # rpm -qa|grep -iE 'libvirt|kvm' libvirt-cim-0.5.12-0.7.16 libvirt-python-1.2.5-1.102 libvirt-client-1.2.5-15.3 kvm-1.4.2-47.1 sles-kvm_en-pdf-11.4-0.33.1 libvirt-1.2.5-15.3 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. 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 the hd again to the origin raw file ? What i found in the net wasn't complete clear. Thanks.
