Re: [Xen-devel] Re: Attempt to load 2.6.29-rc3 with pv_ops suppot for Dom0 under Xen 3.3.1 Hypervisor

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

  I've removed Xen 3.3.1 and installed the most recent unstable Xen Hypervisor.

# cd /usr/src/xen-3.3.1
# make uninstall
# cd ..
# hg clone http://xenbits.xensource.com/xen-unstable.hg
# cd xen-unstable.hg
# make xen
# make install-xen
# make tools
# make install-tools

Tried following two options:-

title Xen 3.4 / Ubuntu 8.10, kernel 2.6.29-tip
uuid   c841c5e9-8eb2-4e47-b36e-6796e5ce6ce6
kernel /boot/xen-3.4.gz
module /boot/vmlinuz-2.6.29-rc3-tip root=/dev/sdb1 ro console=tty0 earlyprintk=xen pci=nomsi
module /boot/initrd-2.6.29-rc3-tip.img

Loading starts up and drops to stack trace immediately after

title Xen 3.4 / Ubuntu 8.10, kernel 2.6.27-xen
uuid   c841c5e9-8eb2-4e47-b36e-6796e5ce6ce6
kernel /boot/xen-3.4.gz
module /boot/vmlinuz-2.6.27.5 root=/dev/sdb1 ro console=tty0
module /boot/initrd-2.6.27.5.img

Seems to work OK with Novell's Xen-ified kernel

Only extremely recent xen-unstable hypervisors (circa last week) can
load a bzImage format kernel for dom0 (which is what "make install"
will
have given you) -- you need to use the vmlinux file from the toplevel of
the kernel build directly (optionally stripped+gzipped) or upgrade your
hypervisor.
