So a little bit of background.

I have a vm which I know boots properly as an HVM and I want to run it
as a paravirt guest. It is a fedora 11 based image that I built from a
kickstart so I know the kernel has paravirt guest support. I have built
the latest xen-unstable tree including the stub domains to get pvgrub to
attempt to boot from. My domU config has the following lines in it.

kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra = "(hd0,0)/boot/grub/menu.lst"

If I remove my storage devices from the config it boots into the grub
console so I know the stub domain is working. When I leave the the
storage devices in and boot with xm create -c <configfile> I get the
output below and then it hangs.

Is there any additional debug information that I can grab to try to
figure this out?

James,
    if you see "grubdom>", this maybe grub can't find its config file
    Check your harddisk partition number to make sure that is correct or
check the position of grub config file

Dongdong Zhang

Subject: 答复： Re: [Xen-devel] about pvgrub

Thank Zhigang Wang for your response. I have test pvgrub with this
config file:

#pv-config
kernel = "/usr/lib/xen/boot/pv-grub-x86_32.gz"
extra = "(hd0,5)/boot/grub/menu.lst"
memory = 512
name = "ExampleDomain"
disk = [ 'file:/var/lib/xen/images/opensuse11-1/disk0,xvda,w' ]
vif = [ "bridge=eth0" ]
root = "/dev/sda5 ro"

start pvgrub with "xm cr pv-config -c"
only see the grub command line like this:
    GNU GRUB  version 0.97  (524288K lower / 0K upper memory)

       [ Minimal BASH-like line editing is supported.   For
         the   first   word,  TAB  lists  possible  command
         completions.  Anywhere else TAB lists the possible
         completions of a device/filename. ]

grubdom>


what's wrong?

This should due to the bad virtual framebuffer support in xenfb.

see bug: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1365

you can try without:

> vfb = [ 'type=vnc,vnclisten=127.0.0.1,vncdisplay=1' ]
