I agree with Tim. I have just about the same setup as you at
home, dual core, 4GB and I am running x86_64 with 32bit domUs
and the only way I was able to get them to run reliably was
using the Xen 3.2 from xen.org.
I hope 5.2 finally moves completely over to 3.2 with all it's
features instead of this Frankenstein version it has where it
glues the Xen 3.0.3 user land tools onto a highly patched 3.1
hypervisor forcing the user to try and use their swiss army
knife libvirt to manage the mess. Ugh! I just want Xen and
to manage it through Xen!
