Hi Pasi,
With reference to http://download.oracle.com/docs/cd/E11081_01/doc/doc.21/e10898/templates.htm#BABGBGHA ,
vif = [ 'type=ioemu, mac=00:16:3e:09:bb:c6, bridge=xenbr2, model=e1000']
Can I omit type=ioemu?

Hi Pasi,
I am not sure whether I can install PV drivers in Rocks HPC Cluster software 5.1 x86-64 (based on CentOS) HVM virtual machines. When I tried to install Rocks 5.1 x86-64 as a PV guest, it complains "invalid kernel" and something about the ELF kernel image. So I guess PV is out for Rocks.
To set e1000 (virtualized Intel Gigabit NIC), I have to use the model parameter in vif in HVM config? Will I get gigabit speeds instead of the Fast Ethernet 100Mb/s speed with virtual Realtek NICs?
Thank you.On Sat, Nov 7, 2009 at 7:17 PM, Pasi Kärkkäinen <pasik@xxxxxx> wrote:

Do you have PV drivers installed in the HVM guests? if not, use e1000 NIC.
