similar to: Increasing throughput on xen bridges

I have a beefy machine (Intel dual-quad core, 16GB memory 2 x GigE) I have loaded RHEL5.1-xen on the hardware and have created two logical systems: 4 cpus, 7.5 GB memory 1 x Gige Following RHEL guidelines, I have it set up so that eth0->xenbr0 and eth1->xenbr1 Each of the two RHEL5.1 guests uses one of the interfaces and this is verified at the switch by seeing the unique MAC addresses.

Hi, I''m doing some test on a network 10 gb nics and xen with version 3.1 i''m measuring 2.5 gb/sec from domU to an external physical machine with iperf. switching to 3.2 has reduced the measured performance to 40-50 Mb/sec. did anything change in the network interface? can someone help me? thanks _______________________________________________ Xen-users mailing list

Hi everyone, I need to port over an old RHEL3 box to a xen domU (just for a little while until I can transfer all of its services over to a new domain). I was hoping to get a domU supported kernel so I can run it as a PV guest and found this page: http://xen.org/download/dl_304guest_rhel3.html ...but the links to the actual kernels come up with 404 errors. Anyone know where I can get this
