Re: [Xen-users] GPLPV Network Driver causing VM crash

[Mark Pace <pace@xxxxxxxxxxxxxxxxxxx>]

Sweet.  Thanks James.  That did the trick.

Would this 3.3.0 bug affect the Windows VMs regardless of the PV drivers?

When I bring a Windows VM up with the GPLPV drivers, it runs until I
    

try
  

to do anything with the network and then it crashes.  Trying to web
    

browse
  

will lock the VM up, RDPing to it will lock the VM up.  I've tried
    

0.9.11
  

and 0.9.12pre13, both with the same results.  I've removed the
    

type=ioemu
  

from the vif line without any change as well.

Any ideas?

    

Add this to your domu config, all on one line:

cpuid =
['0x80000005:ecx=xxxxxxxxxxxxxxxxxxxxxxxxkkkkkkkk,edx=xxxxxxxxxxxxxxxxxx
xxxxxxkkkkkkkk']

that will correct a bug in 3.3.0 where it wasn't exporting the cache
line size to windows, which would cause Windows to hang the first time
it received a packet making use of rx csum offload. It only affects AMD
cpu's.
