[Xen-users] problem about network in Xen! 
| | HI, I have been stuck by this problem for the whole week. We just did a simple experiment to test the network performance in xen use 
the benchmark--iperf. Our NIC is Gigabit, and we got exactly correct 
data in hostOS--fedoral core 8 without xen running, the bandwidth of the network 
was 931Mbps. But the problem is, when we start guest OS--fedoral core 8, and 
running iperf on it, we got data only 48Mbps! The data is same as that used 100M 
NIC.   Can you tell me, are there some restrictions in xen when use Gigabit 
NIC? Or should we do some configuration to use it? Maybe I miss some configurations or make some mistakens.   Thanks for looking.   Regards, Sharon 2008-05-07
