[Xen-users] Re: [Xen-devel] Re: domUloader Vs pygrub

[jd <jdsw2002@xxxxxxxxx>]

Thanks for the interesting background info.

Would you know bit more about the domUloader not being
able to mount unpartitioned disk ? If there is a patch
available for SLES 10 SP1 ?

I will definitely check out the vm-install and see if
that can be used.

Thanks
