Some "enterprise" distros and their kernel version:
- Oracle Linux 5/6: 3.0.x (when using kernel UEK2). Should be
installabe on RHEL/centos as well, but you won't get the support
- SLES11 SP2: 3.0.10
- Ubuntu 11.04 (when it's released): 3.2.x

Judging from the mails to this list from debian users, I wouldn't
recommend using their built-in xen+kernel packages. Period.
