Re: [Xen-users] XCP and Gluster

[Scott Damron <sdamron@xxxxxxxxx>]

Are you actually thinking of XCP here when you say don't have any
disks in the servers?  I don't think that is an option, as it uses
local disk when bringing up a VM, I believe this is the default
behavior.  Then there is his question about Infiniband.  ipoib may be
supported in XCP, but plain Infiniband is not.  I imagine a person
could fiddle around and get it working, but it wouldn't be stable
enough from what I have seen.

Thanks,

Scott
