PoD, 4.2, and current/maximum reservation
A user has pointed out a problem with GPLPV under Xen 4.2 when using PoD. I''m using the difference between XENMEM_maximum_reservation and XENMEM_current_reservation to tell me how much I should balloon down to account for PoD, but when the user has ballooned down to 1G (from 4Gb or 8GB), GPLPV logs the following:
13005008825593: XenPCI XENMEM_maximum_reservation = 262400

State of GPLPV and Windows 8
What is the state of GPLPV and Windows 8? I am currently running tests
with Windows 8 and GPLPV rev956 and operations (disk IO, net IO) look
good. There seems to be a problem with shutdown/reboot where Windows
hangs somewhat and displays a warning about improper shutdown on next
reboot.

network misbehaviour with gplpv and 2.6.30
With GPLPV under 2.6.30, GPLPV gets the following from the ring:
ring slot n (first buffer):
status (length) = 54 bytes
offset = 0
flags = NETRXF_extra_info (possibly csum too but not relevant)
ring slot n + 1 (extra info)
gso.size (mss) = 1460
Because NETRXF_extra_info is not set, that''s all I get for that packet.
In the IP header though, the total length is 1544 (which in itself

Problems with GPLPV network latency
Hi,
DomU is a Win2008 R2 64
When i install the GPLPV drivers the network latency goes from 15ms to
random numbers up to 1200ms and eventually dies. If you run a ping from
the DomU to another host the network stays alive but the high latency is
still there.
Further more if i try and uninstall the network driver i am unable to
use the old one (realtek) as it cannot detect the device.

hang on restore in 3.3.1
I am having problems with save/restore under 3.3.1 in the GPLPV drivers.
I call hvm_shutdown(xpdd, SHUTDOWN_suspend), but as soon as I lower IRQL
(enabling interrupts), qemu goes to 100% CPU and the DomU load goes
right up too.
Xentrace is showing a whole lot of this going on:

0x000000008020632a, eax = 0xffffffff ]

W2k3 HVM domain QEMU drivers
So I successfully installed the GPLPV drivers in a Windows installation I
have running under Xen. Turns out SP2 is needed - I wish this was slightly
better documented somewhere, as the machine ended up bluescreening and I had
to use /NOGPLPV to get it to boot again so I could upgrade it to SP2.
My question is this: I ended up using ''disable'' in device manager for the

GPLPV uninstaller
I''ve just uploaded a couple of .bat files to
http://www.meadowcourt.org/downloads/gplpv_uninstall_bat.zip that will
manually (and forcibly) uninstall GPLPV from your computer, which seems
to be necessary before doing upgrades from some versions. Run the
uninstaller, reboot, then install. There is a 0.9.x and a 0.10.x
uninstaller, which differ slightly, but the basic steps performed are:

Multiple IRQ''s in HVM for Windows
I really need to have the ability to tie event channel port''s to
interrupts for my gplpv drivers under Windows. Is anyone working on
anything like this? Does MSI allow more than one interrupt per PCI
device?
Thanks

GPL PV TAP cow incompatible?
Hi
Is it true that the GPLPV drivers is incompatible with QCOW images?
The Windows DomU works fine with raw standard "file:/" images, and
paravirtualized Linux DomU works fine with QCOW and raw images.
If i use QCOW images with my Windows DomU''s i get a stop error:
0x00000007b (inaccessible boot device).
It looks like the blkback.3.hda process, that normally starts with

GPL PV Intermitent Network Problems
Well, I seem to have developed a strange issue with the GPL PV drivers
in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows
XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two
of them, though, have started exhibiting a strange behavior with
intermittent network connectivity. Basically, the network starts up and
connects initially. After some

Windows 2008 SBS suddenly disappearing on Xen 4.0.0
Hi all,
when running Windows 2008 SBS on Xen 4.0.0, it disappears after some time (longest time I had it running was 20 minutes). In /var/log/xen/qemu-dm-win1.log I find:
xc_map_foreign_batch: mmap failed: Cannot allocate memory
xc_map_foreign_bulk error 12
Anyone any idea how to troubleshoot this? The Hypervisor has 16 GB of RAM, currently 2 GB are allocated to Dom0. This specific DomU has 8

HVM windows - PCI IRQ firing on both CPU''s
I''m just doing some testing on the gplpv drivers with different ways of
handling interrupts, and I''m trying a scheme where each xen device (eg
vbd/vif) driver attaches to the same IRQ as the pci driver, and each
handles it in sequence.
In testing though, I noticed the following when logging what each ISR is
doing:

GPLPV drivers update
I have just uploaded a new testing version of GPL PV drivers for
Windows. Have a look for 0.10.0.97-dontuse at

people away who haven''t read this email :)
As usual, please test thoroughly on a test DomU and make sure you have a

GPLPV, clock drift and PVUSB in Windows XP HVM
1. Shouldn''t the GPLPV drivers take care of the (bad) clock drift I''m experiencing in my Windows XP HVM? Or is there some other way around this problem that I haven''t been able to find on Google? How can I tell if the GPLPV drivers are active? I''ve added the /gplpv switch to the boot.ini file and the virtual NIC is definitely using the GPLPV version but other

GPLPV drivers suspected to hinder live migration to different CPU type
Hi,
I''ve noticed that on a Xen cluster with three nodes (two E5620 CPUs and
one E5140 CPU) live migration works perfectly in between to two E5620
nodes, but fails to and from the E5140. The error message is about a HVM
context not being able to be set.
I strongly suspect the use 238 GPPVL drivers, but I cannot uninstall
them at this point because someone else needs the server.
