I have XEN 3.3 on Centos 5.4, my network interface have link 1 Gbps I want improve speed of network interface on virtual machine, from 100Mbps to 1Gpbs.

AFAIK there is no 100Mbps limit on DomU virtual NICs. They may show up in DomU as 100M but that's just an emulated NIC and not real hardware. I think the only limit is the speed of the real NICs and the ability of Dom0 to process packets.

I think this latter bit is the most likely. I believe the code is single threaded and there have been lots of threads on this list over the years about poor network performance in DomUs
