RE: [Xen-users] Xen GPL PV, W2k3 SBS, Xen Net driver

[Markus Plischke <m.plischke@xxxxxxxxx>]

I had the same problem when I tryed to install the GPLPV Drivers on a 
production Windows Server 2003 R2 with Exchange 2007 installed. If I boot 
without GPLPV the network is fully functional but with GPLPV the network does 
not work because it is not configured and I cant configure it, I cant open the 
Network Configuration.

My Workarround for this is to install a new Exchange, install Windows Server 
2003, the GPLPV Drivers, configure it and then install ADS and Exchange. Now 
the Server runs with and withount the GPLPV boot flag (with GPLPV the 
performance is excellent).

If there is another Solution that would be great, I cant find the post from 
James.


The main problem is ADS/Exchange that blocks all activities if there is no 
network configuration I think. Also with DHCP I have the same problem.

Hi James,

i'll look for the posting you've mentioned.

Here a short overview of the system:

The Hypervisor used is:

(XEN) Xen version 3.2.1-rc1-pre (buildd@buildd) (gcc version 4.2.3 (Ubuntu 
4.2.3-2ubuntu7)) Fri Apr 11 01:13:51 UTC 2008

(I know, RC1 pre ... but otherwise _really_ rock solid)

The particular domU is a Windows 2003 SBS 32bit w/ all Servicepacks installed.

      ]
disk = [
        'phy:/dev/vg0/exchange-sbs-disk-c,xvda,w',
        'phy:/dev/vg0/exchange-sbs-disk-d,xvdb,w',
        'phy:/dev/vg0/exchange-disk-e,xvdc,w'
       ]

vnc=1

vncviewer=0
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'



I currently don't know which of the qemu-dm-*.log files were written with 
/gplpv enabled. I don't expect any differences but will peek into this after 
business hours.


Another domU running a Windows 2003 Server w/ all available Servicepacks is 
running without any problems. Config is similar:
name = 'blackberry.hvm'
kernel = '/usr/lib/xen-ioemu-3.2/boot/hvmloader'
builder = 'hvm'
device_model = '/usr/lib/xen-ioemu-3.2/bin/qemu-dm'
memory = 1536
shadow_memory = 8
vif = [
        'mac=00:16:3e:14:82:25,type=ioemu,bridge=eth1'
      ]
disk = [
        'phy:/dev/vg0/blackberry-disk-c,xvda,w'
       ]
boot = 'cd'
localtime='0'
acpi=1
apic=1
pae=1
vcpus=1
usb=1
usbdevice='tablet'
vnc=1
vncunused=1
keymap='de'
vncviewer=0
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'


You might note that there's a bridge bound to dummy0, this is correct. I don't 
think this causes the problems as the other HVM domU formerly used this bridge 
also without a problem.



cheers,

Stephan
