8.04 server + ubuntu-xen-server dies under disk load on AMD Opteron

[Sam Howard]

Hi.

I have thought about it, however I've not done anything with KVM and our
existing server base is all Xen (currently on Debian Sarge servers with
Etch, Gusty, and now Hardy guests), and we've had very good luck with it
since Xen 2.x.  Much better performance than our old UserModeLinux farm.  :)

We have new servers coming in that are AMD64 x2 based, so not quite the same
as my Opteron test system ... our current servers are all AMD Athlon and
have been very stable for years, so I have to make something work well on
these new servers.  :)

I'm not even where to start looking at KVM and migrating guests and all of
that ... any good pointers?  :)

Thanks,
Sam
