Hello,
We're M.Sc students at Tel-Aviv University trying to setup a basic ovirt
system with 2 hosts.
Both run Fedora Core 17.

We've run unto a problem that makes the hosts seem down from the web
management UI and stops the VMs that run on them.
this occurs on both hosts at the very same second, which leads me to
believe it's not a hardware problem:
("segfault" is the name of the server. don't ask.)

Has anyone seen something like this?
any suggestions?
Thanks,

Yuval Meir
Limor Gavish
