...and nothing more.



I was hoping somebody could point me in the right direction as to what to do to get it to boot.

Dom0 is Ubuntu gutsy and DomU is debootstrapped with gutsy too.
Ran: apt-get install libc6 bridge-utils libxen3.1 linux-xen python-xen-3.1 xen-docs-3.1 xen-hypervisor-3.1 xen-ioemu-3.1 xen-tools xen-utils-3.1 lvm2 dmsetup libdevmapper1.02.1 libdevmapper-dev xfsprogs on Dom0


xen config looks like:

kernel = "/boot/vmlinuz-2.6.22-14-xen"
ramdisk = "/boot/initrd.img-2.6.22-14-xen"
memory = 1400
name = "hudson"
vcpus = 4
vif = [ 'bridge=xenbr0' ]
disk = [ 'phy:mapper/vmachines-hudson,sda1,w','phy:mapper/vmachines-hudson--swap,sda2,w' ]
hostname= "hudson"
root = "/dev/sda1 ro"
extra = "3"

Thanks

Darragh
