CentOS virt - Jun 2009 - fully virt Xen DomU network question

Hello all fellow CentOS users!

I have a working xen setup with 3 paravirt domUs and one Windblows 2003
fully virt domU.


There are to virtual networks.

As far as I can tell in the paravirt Linux DomUs I have gigabit
networking, but not in the fully virt Windows 2003 domU....

Is there a setting for this, or is it not yet supported?

I run xen-3.0.3-64.el5_2.3


Kind regards,
Coert

Both networks should be available in the Linux and the Windows domU's.
Could you send the Xen configfiles for the domU's ? They should list
to which network each domU gets attached.

Are you talking about the virtual network interface appearing to be 100Mbps?  If
so, that's just how it is because the qemu driver is written to emulate a
Realtek card, which happens to be 100Mbps.  A PV interface will look exactly
like the underlying hardware.

That's not on the dom0 side, but directly in the w2k3 domU .. : you'll 
get *bad* performances (at IO and network level) if the xenpv drivers 
for Windows aren't installed .. Unfortunately you will not be able to 
find them for CentOS. (While Upstream have them of course)
