Hi,
I'm currently looking to add live snapshot support to proxmox kvm distribution.
Is it possible to use internal snapshots on a running guest running qcow2 disk?

Or do I need to use exter

Thank Stefan,that's clear now.
Maybe one more question, about qemu snapshot that I don't understand.
I work since many years with snapshot on zfs or netapp,
and on these system like ceph, I can rollback at the time of the snapshot, and
have a view of when the snapshot was taken.

Hi,
A few things:

Currently working on a patch to fix things. Sneak preview,
setting up the helper arguments looks much nicer now:
argreg = TCG_REG_R0;

argreg = tcg_out_arg_reg32
Executed another test:
F16 KVM <-- 15 gbps --> F17 VM
So why is F16 much faster?
