I just got my back up xen machine updated to squeeze and started a new
guest on it to test the upgrade procedure for the production machine.
I'm using Dom0's kernel (no pygrub), installed the base system via
debootstrap and I don't have linux-image-2.6.32-5-xen-amd64 installed
on the DomU:
rocket.cfg
#-*- mode: python; -*-
kernel = "/boot/vmlinuz-2.6.32-5-xen-amd64"
ramdisk = "/boot/initrd.img-2.6.32-5-xen-amd64"
memory = 2048
name = "rocket"
vif = ['bridge=xenbr0']
disk = ['phy:/dev/debian1/rocket-root,xvda1,w',
'phy:/dev/debian1/rocket-home,xvda2,w',
'phy:/dev/debian1/rocket-tmp,xvda3,w',
'phy:/dev/debian1/rocket-usr,xvda4,w',
'phy:/dev/debian1/rocket-var,xvda5,w',
'phy:/dev/debian1/rocket-swap,xvda6,w']
ip = "192.168.1.7"
netmask = "255.255.0.0"
gateway = "192.168.1.1"
hostname = "rocket"
root = "/dev/xvda1 ro"
extra = "console=hvc0 xencons=tty clocksource=jiffies"
So the short of it is that I can confirm that the set up works without
pygrub. However, I noticed that you specified ext4 in the
xen-tools.cfg and I have seen elsewhere that people have had trouble
with the defaults being wrong when file systems other than ext3 are
specified.
