Re: [Xen-devel] Domain0 booting on LVM device
Ok, this may be a dumb question, but I wasn't aware I was using an
initrd image ... I don't see any evidence of it in my menu.lst.
I have built my xen0 kernel with everything static (I don't do a lot of
modules).
In my .config, I have "CONFIG_BLK_DEV_DM=y" ... shouldn't that take care
of it?
What's really bizare is that I can create guests over LVM LV's with the
same kernel....
Thanks!

Same here.
You most likely don't have an initrd image that has the Device Mapper
modules built into it. I don't have much experience with Debian but with
SLES9 the mk_initrd script does this for you as long as you have
compiled the dom0 kernel with the "Device Mapper support" as modules.
In Fedora-type systems it's mkinitrd. If you don't use the same type of
root filesystem on the domU kernel as on the dom0 kernel, you may need
to mount the domU / filesystem TEMPORARILY and use the --fstab option
to mkinitrd to specify domU's /etc/fstab.
I also had to uncompress my initrd image using gunzip.
Weird, I didn't have to do that with Fedora. What error did you get
when you tried to boot with it uncompressed?
As a result of
this I had to increase the size of the initial RAM disk (under Block
Devices) in the dom0 kernel.
Cheers,
Aravindh
