Hi guys,
I have a CentOS system with virt-manager installed on it,
the system is installed on a LVM partition with one PV for swap and one 
for "/",
I only use KVM and qemu virtual machine on this server,
I want to do a backup from my Virtual Machines on this server
should I use LVM backup or an other stuff to do these backups ?
what should I do ?
stopping all VM before backup (I think)
then do a LVM backup

all help is appreciated
