Where is the paradigm shift with this kernel? I have a Karmic 9.10 server domU 
running under Xen 4.0 in SuSE11,2.

The domU kernel is linux-image-2.6.31-20-virtual_2.6.31-20.57_amd64.deb with 
these paravirt flags

I use pygrub to boot a fake grub1 menu.lst, although the domU still has grub2 

To install this domU I had to start with an HVM xm config, then convert later 
to PV with pygrub.
------------ karmic_hvm.py ---------
disk = [ "phy:/dev/virtvm/ubdomu,hda,w", 
"file:/data2/kvm/ubuntu-9.10-server-amd64.iso,hdc:cdrom,r" ]
extras = "console=tty0 console=ttyS0,34800n8 console=hvc0"
name = "karmic"
uuid = "393d4465-85a4-1d1f-e1d2-7eeeedf8884d"
maxmem = 784
memory = 784
vcpus = 2
type = "hvm"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1" ]
boot = "c"
vif = [ "mac=00:16:3e:46:53:f2,bridge=br0,script=vif-bridge" ]

can you tell us how long it took to compile the pv_ops kernel and about how 
much your free space was reduced? I know at least 3 GB will be reduced.

Will your domU's be all Ubuntu and will they still use pygrub, or will the 
newer kernel enable boot using the emulated bios?
