[Xen-devel] HVM NFS boot problem with 2.6.31 dom0 and xen 3.5
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:
