Hi James, On Wed, Nov 19, 2008 at 7:27 AM, James Harper <james.harper@bendigoit.com.au> wrote:> I''ve just uploaded 0.9.12-pre4 to http://www.meadowcourt.org/downloads > > Fixes/updates since 0.9.12-pre3: > . rolled back IRQ restriction which would prevent the drivers from > starting if the pci device wanted to use an IRQ < 16Yup, this fixed my issue. Things are looking good now. This is just my virtual XP workstation for Outlook and a couple of other programs, but so far I''d say it ''feels'' better. It''s obvious the network driver is configured, as it''s all that shows up in the network applet now. I see the Xen Block Device Driver in the scsi section of the device manager, but is there any clear way to verify the PV block device is active? Powershell certainly seemed to load 4-6 seconds faster. In the future, would I just install new versions over the top of the current version? In any event, thanks a ton for all your help getting this up and going. Hopefully my XP vm won''t be as painfully sluggish any more; the underlying machine is certainly fast enough.

Powershell certainly seemed to load 4-6 seconds faster.I think PV block device is active and work fine if you can see Xen Block Device Driver in scsi sections of device manager. And you can check disk volume section in device manager. If you cannot see ''QEMU disk...'', that means PV block device works fine.

There is no mechanism to notify disk change in the pv communication path. That said, block-detach and block-attach appear to work just fine. Obviously doing a block-detach to a device with a page file or something on it isn''t going to work but I just tested it on a cdrom image and it worked fine.

Re: [Xen-users] GPLPV 0.9.12-pre4 uploaded - Windows starup/login problem ?
James, Have you already fixed your login/startup problems ? (You said it was so slow..) I have had some of those things before (with other non-virtual servers); - Check you event log (Application and System) for errors. - Is your server in a Domain or is it a Domain controller itself ? (you can have (domain) group policy problems..) - Sometimes the network drivers load to slow.. (keep in mind that the switch and network card probably also do some SpanningTree/Portfast things.. but that''s no issue with Vm''s i think ;). If the network drivers get loaded to late... the DHCP and other services get into problems... sometimes you see results of that in the event log. You should also see in the event log when the network driver is loaded (or maybe you should program some debug code in the network driver, so you see the startup time..) Hope this helps..

Hi
Just tested 0.9.12-pre4 with Windows 2008 standard server, 32-bit.
Using iperf from Dom0 (client) -> DomU (server)
Dom0 is CentOS 5.2, 64-bit
Xen 3.2.2
Bridged VLAN interfaces on use.
With 0.9.11 Drivers, checksum offloading enabled, large send offload
enabled (61440 bytes), Windows firewall enabled:
[ 3] 0.0-10.0 sec 1.12 GBytes 964 Mbits/sec
With 0.9.12-pre4 (dated 19.11.2008, v0.9.11.4), Check checksum on RX
packets disabled, checksum offloading enabled, large send offload enabled
(61440 bytes), Windows firewall enabled:
[ 3] 0.0-928.7 sec 835 KBytes 7.37 Kbits/sec
Best case scenario ATM is:
[ 3] 0.0-26.1 sec 1.91 MBytes 612 Kbits/sec
So atleast under Windows 2008 server current 0.9.12-pre4 dont seem to work
with iperf, but i also downloaded files from internet, it seems to work ok
(with 0.9.12-pre4).
My Xen configuration for this windows 2008 is here:
--------------------8<------------------------------
import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
arch_libdir = ''lib64''
else:
arch_libdir = ''lib''
device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''
name = "win2008test"
maxmem = 2048
memory = 2048
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "dc"
pae = 1
acpi = 1
apic = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
sdl = 0
vnc = 1
vncunused = 1
disk = [ "phy:/dev/mapper/win2008test,hda,w",
"file:/mnt/images/en_windows_server_2008_datacenter_enterprise_standard_x86_
dvd_X14-26710.iso,hdc:cdrom,r" ]
vif = [ "mac=00:16:3E:71:F8:46,bridge=br13" ]
serial = "pty"
usbdevice = "tablet"
usb = 1
localtime=1
keymap=''fi''
--------------------8<------------------------------
Any ideas why iperf so slow with 0.9.12-pre4 ?

[Xen-users] GPLPV 0.9.12-pre4 uploaded
I''ve just uploaded 0.9.12-pre4 to http://www.meadowcourt.org/downloads
Fixes/updates since 0.9.12-pre3:
. rolled back IRQ restriction which would prevent the drivers from
starting if the pci device wanted to use an IRQ < 16
. fixed another bug in crash dump that could possibly cause corruption
under high Dom0 disk load
. performance improvements to xennet - udp performance is much much
better, I can easily achieve 500MBits/second from Dom0<->DomU or
DomU<->External machine over 1GBit/second wire. Tcp performance should
be as good as before but with lower cpu.
To see some of the the network performance improvements, you''ll need to
disable ''Check checksum on RX packets''. It only exists as WHQL
fails
without it, even though it isn''t a real-world scenario. The
''interrupt
moderation'' option appears to cause things to go slower at the
moment...
it may reduce load but I think it needs some more tuning!
If anyone can offer any suggestions as to why my Windows 2003 R2 server
takes so long to get to the login prompt after boot with GPLPV but is
quicker without it I''d like to hear them - it seems to get
it''s dhcp
lease quickly enough so something else about the network adapter or
about the gplpv drivers must be causing the delay...

Hi James!
With Xen 3.4 unstable and GPL PV 0.9.12-pre4 I finally managed to get
W2k8 64bit running on my server (with -pre3 Windows complained about a
resource problem for the Xen PCI driver). One thing I have noticed is
that pings most times have < 1ms latency (okay) and sometimes about
15ms. The destination (dom0, domU, network connected device) seems not
to play a role. Do you have an idea what''s happening here?
See below for sample ping output (W2k8 in German, that''s why the
messages are in German).

Hello James,> How many vcpu''s does your Dom0 and your DomU have?Dom0 as well as DomU have 4 vcpus corresponding to the 4 installed cpu cores.> Can you make sure that ''rx interrupt moderation'' is disabled?

Hi! I just tested 0.9.12-pre4 on a fresh 32-bit windows 2008 with Xen version 3.3 (64-bit). After setting the IP address the (guest-)system freezes as soon as Windows tries to "identify" the network. Using an older version (0.9.11), the identification process comes through but as soon as some packets traverse the network interface the system freezes again. After disabling "checksum offload" in the driver settings the system runs stable with both mentioned versions of the GPL''ed drivers. Is there anything I can do helping to debug this bug?

There are some issues: 1, Vista notify me to reboot system again after I installed winpv driver and reboot system with gplpv start options. 2, DVD device also cannot work fine. DVD device can be enumerated by xenvbd driver. Capacity is OK. But when I try to open it, Vista tell me that it need ''UDF'' file system support. That''s the same issue I have meet in my pv drivers.

I uploaded 0.9.12-pre7 a few days ago but had to delete it from the download site as it caused some problems. I hope to have a new version uploaded shortly. You can view the fix I am thinking of here: http://xenbits.xensource.com/ext/win-pvdrivers.hg?diff/3a2121285fc9/xenv bd/xenvbd.c but maybe that doesn''t fix it for you and there is another problem?

> You can view the fix I am thinking of here: > http://xenbits.xensource.com/ext/win-pvdrivers.hg?diff/3a2121285fc9/xenv > bd/xenvbd.cI also have done that in my winpv drivers. But DVD device just can work fine on XP/Srv2003. In vista, I just can see a readme file for that DVD device. But the same DVD device can work fine on QEMU mode.
