I don't know what is considered stable, but here is what has been very stable in my lone-sysadmin-shop for the past several years at least. A current-LTS Ubuntu KVM host running current-LTS Ubuntu guests (variable number, but up to a dozen or so). VM images are stored in Btrfs partition. Each guest does its own, standard to all our machines, backup routines, agnostic of it being a VM or not. On the KVM host there is a cron job that: 1) "freezes" guest filesystems (using QEMU Guest Agent); 2) makes a btrfs snapshot (takes milliseconds); 3) "thaws" guests. Btrfs snapshot(s) then can be rsync'ed, backed-up as needed.
