[Xen-users] Avoid resources(disks) conflict on a multiserver envorioment

["Luiz Angelo Daros de Luca" <luizluca@xxxxxxxxx>]

Hello,

I have 3 servers connected to a SAN (EVA 4100) providing my xen disks.
If I try to run two machines with conflict access in the same server,
xen shows me an erros and quits. However, I can still bring up the
same virtual machine on two servers, which migth lead to some disk
problems :-)

Is there any way to automagicly avoid xen conflics over some dom0
servers? (not letting me turn on one vm if it is up in another server)

I'm trying to implement some checks on the vm config file (as it is
python) and using file-based locks on a ocfs2 partition. It's not
quite clear
but it is the best I found until now.

Any better ideas, please?

Thanks,
