Re: [Xen-users] 2 node - failover cluster

[Jean Baptiste FAVRE <xen-users@xxxxxxxxxxx>]

Hello,

DRBD and GlusterFS are not on the same level: you can have a DRBD 
resource formatted with GlusterFS.
In your situation, you'll have a DRBD resource formatted with either EXT 
FS or NTFS. I'm afraid GlusterFS won't help you here.
Regarding live migration, use of DRBD (or centralized storage, which you 
don't have) is mandatory.
regarding failover cluster, either use Remus with Xen4 or build a 
cluster with thing s like Pacemaker/Corosync/Heartbeat so that you can 
monitor VMs and automagically restart them in case of node failure.
VLAN support should be done on Dom0, IMHO.

Regards,
JB
