Thread-topic: [Xen-devel] [PATCH] Fox for pcnet device model data corruption
Yes, the pcnet issue is VMX domain specific. FYI the vmx domains see the pcnet 
network adapter which is actually emulated in the DeviceModel. 
  I believe there is still similar issue for dom0 & domu; and people are 
working on that.

Thanks & Regards,
Nitin

This fix is to VMX domain only.
