The el5 xenconsoled bug:

1) Affected only 32bit (i686) hosts running el5 Xen
2) It was fixed years ago on upstream Xen
3) It is already fixed in rhel5/centos5
4) It didn't affect 64bit (x86_64) hosts running el5 Xen
5) It was easy to workaround by killing+restarting xenconsoled

There are other Xen-based virtualization solutions out there aswell with full support.
