i had run 'depmod -a', as i always do when building opensuse kernels,
with no effect.

i did not realize that "depmod -a 2.6.18-164.10.1.el5.centos.plusxen"
-- which works! -- was required. thanks.

sorry this is becoming a treatise on kernel-building, but i appreciate
the necessity to try to rule out xen ...

atm, i've extracted/installed from the centos rpm, as Fajar
instructed.  i've also run 'mkinitrd -f lvm2 -f md'

so now i have,

ls -al /boot/*el*

i've setup grub, to use the
{vmlinuz,initrd}-2.6.18-164.10.1.el5.centos.plusxen.  at boot, i see
the hypervisor load, and the passoff to the centos kernel.  but it
then gets stuck in a loop, endlessly repeating "volume group VG0 not
found".

fwiw, "/boot" is on a linux native RAID-1 part, and "/" is on a LV on
a RAID-1.  of course, works fine @ boot to opensuse kernel(s).

what else do I need to get that centos kernel to boot my box?  Or is
the 2.6.18* too old for support of LVM, RAID, etc (i doubt that ...)?

thanks.
