Hi Pasi,
Thanks for the response. This seems to have been caused by an update from
CentOS 5.3 to 5.4. I'm not exactly sure what packages were specifically
affected during the update, but after reluctantly rebooting the server, it
came back up and Xen started functioning completely normally. Could quite
easily have been xenconsoled, I suppose.
Xen userland must match the version of hypervisor you're running.
Since upgrading to Centos 5.4 should've include kernel-xen (which also
contain the hypervisor) and xen (the userland), it makes sense that
you have to reboot to have it function properly.
I usually exclude these packages from normal update, and only update
them just before I reboot the server:
kernel kernel-devel kernel-xen kernel-xen-devel xen xen-libs glibc
glibc-common glibc-devel glibc-headers glibc-utils
