I am trying to move a xen vm from one LV to another LV.
I know I can copy the current LV by shutting down the xen vm and doing this
command...
dd if=/dev/VolGroup00/LogVol00 of=/root/wdcdns1.img
How do I at this point mount the image file locally so I can verify its
contents or make changes?
Thanks for any help!

Well, after unchecking the "Show Compatible Hardware" box it still only
shows the existing HAL (non-APIC) and "Standard PC." I'm going to try a
couple other things to see if I can get it installed.

If youÂ?re feeling bold and daring, just switch it, but have a backup
handy. In some cases it will work, in others it wonÂ?t. There is good
documentation out there, but I donÂ?t have hand links to any of it.
Here is what I am suggesting:
1) Device Manager
2) Right click on Advanced Configuration and Power Interface PC
3) Click Update Driver
4) Select Advanced (Install from a list or specific location)
5) Select DonÂ?t Search. I will choose the driver to install
6) Uncheck the Â?Show compatible hardwareÂ? box if necessary (it
probably isnÂ?t)
7) Choose ACPI Uniprocessor PC
8) Proceed through the remaining steps and reboot
As I said, you should certainly have a backup ready, but I believe this
should work (assuming XP/2003 or newer), IÂ?m not sure it was that easy
in 2000, my MCSE class back then said no, but could have been wrong.
Good luck,
Dustin

Subject: RE: [Xen-users] GPL PV Intermittent Network Problems
Well, I've just stumbled upon another couple of things that seem to be
causing the problem. First, in looking at the Computer type (Device
Manager -> Computer Name -> Computer), the working ones all have "ACPI
Uniprocessor PC" and the two that don't work have "Advanced
Configuration and Power Interface (ACPI) PC." On the surface, this
seems to be about the same - even looking at the driver version, date,
etc., yields the same information. However, if I go to the Details tab
of this device and look at "Hardware Ids," I see that the "Advanced
Configuration...PC" shows "acpipic_up" whereas the "ACPI Uniprocessor
PC" shows "acpiapic_up." So, the computer types are actually different,
and, just like when you switch from a single processor to a
multiprocessor configuration, Windows is incapable of picking up the
change from a non-APIC (PIC, I guess??) machine (VM) to an APIC machine
(VM), even though I've switched over the Xen configuration.
Furthermore, if I look at the Device Manager and view as "Resources by
Type" and look at IRQs, the machine that is failing doesn't have ANY
devices assigned an IRQ over 15 whereas the ones that work have a few
other devices (besides the Xen ones) assigned IRQs over 15.
Guess it comes down to a HAL issue at this point - anyone have any good
hints or documents for switching out the HAL?

Nick,
I have built a xenpci.sys that will tell Windows not to give it an IRQ
under 16. Other than testing that it doesn't crash I haven't given it
any other testing. You can download it at:
http://www.meadowcourt.org/downloads/xenpci.sys.no_irq_under_16.xp.bin
rename the downloaded file to xenpci.sys and copy it to
c:\windows\system32\drivers, then reboot.
I also have a windows 2003 version there.
If, for some reason, windows won't assign an irq > 16 to it then a boot
with /GPLPV will probably fail (bug check 0x7b), but you should still be
able to reboot without /GPLPV.
Let me know how it goes. If it boots, assigns an irq > 16, and your
stability problems go away, then I'll keep the fix in there.
Thanks
James

Maybe this is what you want.

Okay, well, stumbled upon the following site:
http://www.nforcershq.com/forum/viewtopic.php?t=12269
The site gives instructions for setting up a boot entry that specifies
the new HAL DLL that you want to use (extracting the new DLL and then
using the /hal= switch to tell Windows to use that HAL). After you boot
with that /hal option, Windows permanently installs the new HAL and then
asks you to reboot. After the reboot, the new HAL is installed and the
XEN drivers are getting the proper IRQs and functioning correctly.
Thanks for the help James & Dustin - just took a little pointing to get
me going in the right direction.
