Re: [Xen-users] While installing guest OS, having error "Invalid kernel"

[Stephan Seitz <s.seitz@xxxxxxxxxxx>]

I assume pygrub does have problems with fancy lvm layouts and/or exotic
filesystems INSIDE domU.
To avoid potential problems, I've done all of my domU disk layouts with a
separate (first and primary) partition for /boot which is always ext3.

Anyway, that has nothing to do with lvm outside domU, pygrub is really
fine with a (dom0's) LV a domU disk .


For your mentioned ubuntu domU, it's necessary to use the kernel / ramdisk
provided by linux-virtual. linux-generic is not xen capable.
you could e.g. install your ubuntu domU fully virtualized (hvm)  with additional
linux-virtual and grub-legacy-ec2 packages. As of 12.04 some kernel modules
are placed into linux-image-extra-virtual (None of them are necessary for a
plain installation, but I recently found myself searching for "lost" modules).
