I am not using pygrub (or at least I am not aware of), the .conf file I give xen is:

kernel = "/boot/vmlinuz-2.6.18.8-xenU"
memory = 2048
#memory = 512
vif = [ 'bridge=xenbr0', ]
disk = ['phy:vm_volumes/vm2_root,sda1,w', 'phy:vm_volumes/vm2_swap,sda2,w']
root = "/dev/sda1 ro"
extra = "fastboot"

and the inittab looks like this (it is a jailtime.org COS5 64bit image):

id:3:initdefault:

# System initialization.
si::sysinit:/etc/rc.d/rc.sysinit

l0:0:wait:/etc/rc.d/rc 0
l1:1:wait:/etc/rc.d/rc 1
l2:2:wait:/etc/rc.d/rc 2
l3:3:wait:/etc/rc.d/rc 3
l4:4:wait:/etc/rc.d/rc 4
l5:5:wait:/etc/rc.d/rc 5
l6:6:wait:/etc/rc.d/rc 6

# Trap CTRL-ALT-DELETE
ca::ctrlaltdel:/sbin/shutdown -t3 -r now

pf::powerfail:/sbin/shutdown -f -h +2 "Power Failure; System Shutting Down"
# If power was restored before the shutdown kicked in, cancel it.
pr:12345:powerokwait:/sbin/shutdown -c "Power Restored; Shutdown Cancelled"

# Run gettys in standard runlevels

Check the inittab of the xen instance and also the options to pygrub
if you are using pygrub.  It appears that output is getting
redirected to a non-existent console device somewhere.  If there
are any co: lines in the inittab of the domU you should take them out,
also if there are any console=ttyS0 lines in the grub.conf of
pygrub take them out
