Thanks, I'll try to check into this. One quick question, though, which
I forgot to ask. When I installed the xen kernel in the guest, it set
up this line in grub.conf:
kernel /xen.gz-2.6.18-92.1.13.el5
Which we haven't referenced anywhere in the config file. Do I need it?
Is that the actual kernel to specify, and if so, how do I specify the
vmlinuz file that is referenced as a "module" in the grub config?
