Xen users - Apr 2011 - windows and type=paravirtualised

Hi!

What benefits do I get if I put "type=paravirtualised" in my network
card
config for a Win2k8 domU with PV drivers installed?
Is it necessary, will it improve performance?

I have read about this option here:
http://plone.lucidsolutions.co.nz/linux/xen/windows/windows-server-2008-r2-xen-hvm-installation-with-gpvpv-drivers

Thanks,
Daniel

Short answer: don''t put any "type" entry.

Long answer:

Using PV device (network and disk) will improve performance, but you
need PV driver (e.g. GPLPV) in domU as well. Withot PV driver, the PV
device will not be used.

Both device (PV and emulated) should be available to domU by default
without any "type" settings. When there''s no PV driver, the
emulated
one will be used. When there''s PV driver on domU, it should be smart
enough to use PV device ignoring (or hiding) the emulated device. So
there''s no need to select "type" explicitly.
