This occurs when you have not booted Windows with the /gplpv option.  Go out to the XEN Wiki and read the Installation page for the GPL PV drivers ( http://wiki.xensource.com/xenwiki/XenWindowsGplPV/Installing ) and follow those instructions.

I am using Suse 10 SP2 and installed the drivers pre4, but the new network
card says "cable not connected". What do I have to do to make the drivers
work in Suse 10 Sp2? Any configuration at the global XEN level?

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...

James
