Goal: NFS boot HVM image

Result: The domU hangs immediately after the PXE TFTP transfer of menu.lst

Are there any HOWTOs on NFS with HVM? All the ones I have found are for PV VMs.

I also tried the 2.6.31.1 pv-ops kernel with the same results.
I can boot non NFS images of the same target with no problem.

Are there any grub tricks I need to know?

I suspect the problem is in my domU config file (below).

Has anyone managed to get an HVM NFS boot working? If so, please,
can I have the details of the configuration?

I know have the tftp server and dhcp setup right as I can boot non-xen
images fine.

Here's the console output:

#> xm create -c /import/bedge/static-nfs.cfg
Using config file "/import/bedge/static-nfs.cfg".

configfile: (nd)/import/tonic/pxe/kaan-14-dpm/menu.lst
bootp called in PXE TFTP mode
dhcp called in PXE TFTP mode

...then nothing.

I know the grub menu.lst was transferred because the tftp server logs:

This is the config:
