I'm currently having a hard time starting a PV domain on my notebook (HP EliteBook 6930p). This is the output of xm create -c config.cfg:

After this line, no more output appears and the domain stays in blocked ('b') state.


This is the configuration file:

kernel = '/boot/vmlinuz-2.6.30-rc6-andi-tip'
ramdisk = '/boot/initrd.img-2.6.30-rc6-andi-tip'
memory = '128'
vif = []
disk = ['file:/myxendomains/c08d06e6-cb72-48ab-88a9-24360beff248/disk0.img,sda1,w']
root = '/dev/sda1 ro'
name = 'c08d06e6-cb72-48ab-88a9-24360beff248'
uuid = 'c08d06e6-cb72-48ab-88a9-24360beff248'

extra = "video=xenfb xencons=tty1"
vfb = ['type=vnc,vncdisplay=10']

vnc = 1


The kernel comes from git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git, with dom0 support deactivated. All kernel modules have been copied to the domain's /lib/module.


I have successfully tested that domain (Debian lenny installed with debootstrap) on another machine that runs the 2.6.18.8-xen kernel which ships with Xen. But on this notebook, only Xen-unstable with 2.6.30-rc6 works, and I can't start PV domains.

Do you have any hints what the problem could be?
