Hi I am developing Window pv network driver and hit a problem now.My server use Xen 3.1.4 and have 2 physical CPUs. When I create two VM with 1 VCPU on a same server, iperf performance is OK between those two VM, but there is performance degradation between those 2 VM when i increase VCPU from 1 to 2. This problem occurs in QEMU mode too.
Does Xen 3.1.4 has such problem or anything wrong in my configure file? My configure file is as following: acpi = 1 apic = 1 boot = 'c' builder = 'hvm' bootloader = '/usr/bin/pygrub' device_model = '/usr/lib/xen/bin/qemu-dm' disk = [ 'file:/mnt/data/win2k3/Sys.img,hda,w!', ] kernel = '/usr/lib/xen/boot/hvmloader' memory = '600' name = 'win2k3_s' on_crash = '' on_reboot = '' serial = 'pty' timer_mode = 1 usbdevice = 'tablet' vcpus = 1 vif = [ 'type=ioemu, mac=00:16:3E:55:D1:80, bridge=xenbr0', ] vnc = 1 vncconsole = 1 vnclisten = '0.0.0.0' vncpasswd = '' vncunused = 1 Thanks Annie. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
