If your talking about needing two Xen hosts so you can run two copies of the

the XenServer ($495)... but more power to you.

lHosting) rather than
using virtualization? That might be true... but there are drawbacks to that.
I mean, you can't give someone root access and allow them to install software,
create accounts, etc in non-virtualized environments. Perhaps I'm not
understanding the alternative you a
hat much of a
spike. I have run OpenVZ at work and on a hobby server. In both cases I have
about 7 containers... one of them being Zimbra. The other 6 containers are
fairly busy so the two machines see a decent amount of load. I am NOT using
GFS though. What is dlm_send and dlm_recv part of? GFS

ee on this (http://www.djbdnsrocks.org/single/getting_started.htm) page they
say, "Virtual private servers (jails) will usually NOT work." That implies
that a VPS is a jail. OpenVZ is much, much more than a jail and I see no
