Re: [Xen-devel] Domain0 booting on LVM device

[Samuel P Howard <sam@xxxxxxxxxxxxx>]

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!
Sam
