[Gluster-users] about HA infrastructure for hypervisors

[Dan Cyr]

If you do decide to use 2 switchs:
1) for KVM Hosts use 2 nics, bridge them and run KVM on the bridge (usually br0), link each nic to a different switch
2) Interlink those switches.

Right. Handling switch failures isn't what I'm most worried about but I guess that I'll need to add a network link between KVM hypervisors, too.

Thanks for this tip, though.
