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?

Actually the qemu-dm-SEHostStorage.log file is wrong. I deleted all my logs rebooted and reran the pvgrub config to get a new log file and it doesn''t seem to generate one. So I guess that the log file I pasted was from when I ran it as an HVM. Were there any other log files needed?

I found that pvgrub doesn''t seem to notice the "extents" feature flag, and will drop into an infinite loop if it encounters a directory with extents (probably any extent-based file will make it upset in some way).

So when I made the image I made 1 partition and its ext3. So the boot information is on the same root partition as the rest of the system. I don''t know if that might be an issue. Its definitely ext3 though. Dave On Fri, 2010-04-02 at 11:45 -0700, Jeremy Fitzhardinge wrote:> On 04/02/2010 10:21 AM, David P.

I just tried removing my extra line which points to the menu for grub while leaving the disk line in and it hangs the same way with the output I posted in the first email.

If I use vfb then I can get the menu displayed, but then it crashes as soon as I select a kernel. If I don''t have vfb then it crashes in a different way. What happens if you don''t point at the menu and just drop into the grub command line? Does that work? Does it hang when you manually select a kernel and initrd?
