Sorry for the top-post...

I had a similar problem on FC5 that was because of some deprecated sysfs stuff.  There's a compatibility setting for those of us with really old userland tools (like LVM)... Don't remember the exact name of it off hand.  I'll look it up when I get to work tomorrow.

Hello everyone.  As I am new to this group I'll be short and try to
explain what I'm doing with enough detail so that someone might be able
to help me out.  First off I have successfully compiled xen-unstable and
downloaded Jeremy's pvops kernel, 2.6.31.6.  I have configured it to the
best of my ability and run built and installed it.  I have executed
mkinitrd, at first this complained about ahci and two usb modules
missing.  I have since found the CONFIG settings to compile them as
modules and now no errors.  I am running Centos 5.3 64bit and have root
installed on a LVM Group and a LV that's formatted with ext3.  My
problem is that the kernel and initrd can't seem to find my LVM Group or
LV's, naturally.  I am at a loss, since I don't have a serial port or
anyway of seeing anything during boot, it's scrolling a bunch of stuff
accross the screen.  How can I troubleshoot this?  Do I need to extract
the initrd img file and start looking at the init scripts to see if it's
not loading LVM or something like that?  Any pointers would be great!
Mike

CONFIG_SYSFS_DEPRECATED=y

Thanks. Trying that now.  Will update as soon as I rebuild.

Ok, got it working with using the below setting.  Now I can boot into
pvops kernel dom0.  Of course, I'm now getting the dreaded xenfs busy or
already mounted error and am getting a no such device back
from /dev/rtc.  Seems like CentOS is just too old for all the new
fangled things in this kernel.  I will research this tomorrow night and
maybe look into grabbing a newer OS in the meantime.
