Re: [Xen-devel] RE: [Xen-users] HVM WinXP dom crash

[jdsw <jdsw2002@xxxxxxxxx>]

Hi
  I tried using xen-3.0.3-testing.hg  followed most of the stuff from 
http://www.broermann.com/howto_amd_hvm.html
Still getting the same problem when I try to start WinXP domU.  Same dmesg message about ROMBIOS. I would appreciate any help getting this and related issues resolved.

Q1  : Is the procedure ok (bit later in email) ? Do I need to do anything else ? (One interesting thing is that the kernel version that I had installed using yum, were 2.6.17-1.2187, while 3.0.3 testing.hg is got 2.6.16.29 !!! )

Additionaly I am seeing the following. These are put here as they might be actual bugs or may help resolve the issue.

A . 
 during startup, Between xend starting and login prompt takes 2 min.!!   I dont know whats going on ?
 some messages in
 dmesg

============  BUILD PROCEDURE ===================
# cd /usr/src/
# hg clone http://xenbits.xensource.com/xen-3.0.3-testing.hg
# cd xen-3.0-3testing.hg
# make world
# make install
# mkinitrd initrd.img-2.6.16.29-xen 2.6.16.29-xen
# ln -sf initrd.img-2.6.16.29-xen initrd.img-2.6-xen

--- disabled ASUS-ACPI
# make linux-2.6-xen-config CONFIGMODE=menuconfig
# make linux-2.6-xen-build
# make linux-2.6-xen-install

-- did the whole procedure twice.. once skipped this two
--- steps (removed and rebuilt, as mkinitrd was compalaining..
# rm initrd.img-2.6.16.29-xen 
# mkinitrd initrd.img-2.6.16.29-xen  2.6.16.13-xen

I had to manually copy xen and grub from /usr/lib/python to /usr/lib/python2.4/site-packages.
Added a new entry in the menu.lst under
 grub.

title Fedora Core TEST (2.6.16.29-xen)
        root (hd0,0)
        kernel /xen.gz dom0_mem=768000
        module /vmlinuz-2.6.16.29-xen ro root=/dev/VG_Fedora/LV2 rhgb quiet
        module /initrd.img-2.6.16.29-xen

booted in Test kernel. And tried to create HVM winxp domu.
