What is your DomU virtual machine? Windows or Linux?

If Linux, try using paravirtualization. For Windows, there's nothing to do unfortunately, as open-source version of Xen does not have paravirtual drivers for the moment. You may try Xensource XenExpress though.

Hi all:
I installed xen3.0.4 on fedora7, which has an Intel Pro/1000 NIC, I use chariot to test the throught between two machine with Intel Pro/1000 NIC, the native throughput was 650Mbps in average, but the throughput between one machine and the Virtual Machine on xen is 67Mbps. I noticed that in the Virtual Machine which I installed in xen, the NIX is rtl8139, 100M, I think this is the reason whay the throughput is 67Mbps.
Can somebody explain this??
Thank you
