I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up because of a initrd issue.
First 4.6 domU:

Hi, I'm moving this thread to the CentOS-virt mailinglist (please remove the centos mailinglist to everyone replying to this mail) since it is more suited for these kind of questions.
Question, If I read those crashes correctly your 4.6 domU is a 32 bit one ? What platform is your dom0 32 or 64 bit? Running a 32 bit domU on a 64 bit dom0 is currently not really stable. This is suppose to improve with 5.2
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!
el 5.2 will be based on xen 3.1.2 _hypervisor_ at least that's what upstream says in the release notes..

"+ Xen hypervisor rebase to 3.1.2"
package list / changes:
xen: 3.0.3-41.el5 -> 3.0.3-55.el5
So yeah.. :)
