[Xen-users] DRBD, Xen, HVM and live migration

[Bart Coninckx <bart.coninckx@xxxxxxxxxx>]

Hi,

I want to combine all the above mentioned technologies.

The Linbit pages warn not to use the drbd: VBD with HVM DomUs.

This page however:

http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en

(thank you Jean), simply puts two DRBD devices in dual primary mode and 
starts Xen DomUs while pointing to the DRBD devices with phy: in the 
DomU config files.
Live migration and HVM seem possible.

Is it as simple as Jean describes it? What is the advantage then of the 
drbd: VBD? Just seeing to it that the dual primary is available?

Thx!


B.
