RE: HVM paravirt block/nic drivers
Hi, Have you compiled XENHVM kernel? It makes some improvements to networking. Ensure you add the correct device to /etc/rc.conf afterwards, I believe it changes to xn0 when running XENHVM.

Re: HVM paravirt block/nic drivers
Well, im using the AMD64 ISO image, So i'll have to recompile the kernel? Are there instructions anywhere? Thanks.
