Thanks guys - the good news is that I can boot the PV DomU with your
fixes:
title Fedora (PV boot, Xen kernel, 2952)
root (hd0,0)
kernel /vmlinuz-2.6.21-2952.fc8xen ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.21-2952.fc8xen.pv.img
name = "fc8-32-001"
memory = 1024
vcpus = 1
vif = [ 'mac=00:0f:b5:ae:4f:2a, bridge=xenbr0' ]
disk = [ 'phy:/dev/VG_Guests/FC8-32-001,hda,w' ];
bootloader="/usr/bin/pygrub"
boot = "cd"
sdl = 1
vnc = 0
I got rid of the root line with no problems. I couldn't boot at all
with the original ramdisk (I got a "mount: could not find filesystem
'dev/root'" error), but had no problem with the xenblk and
xenblock/xennet ramdisks.
The *bad* news is, well, bad. The DomU appears to be Ok at first
sight, but crashes when I run a specific program (wine, which is a
Windows-on-Unix emulator [yes, I know that's crazy, but I need it for
testing]). I get a kernel bug:
kernel BUG at include/linux/tracehook.h:369!
invalid opcode: 0000 [#1]
Should I bother reporting this? The Dom0 appears flakey after this so
I need to restart the entire machine.
Can you do a fast, clean FC8 PV install and test Wine on it?
