A test show that i have no more 6MB/s on a copy ... However i have a Dual Xeon 5520 with 12Go DDR3 ECC and 6x1To SAS RAID5 I have setup XP directly on a physical drive but it's the same thing. Look my config : import os, re arch = os.uname()[4] shadow_memory = 8 kernel = '/usr/lib/xen-default/boot/hvmloader' builder='hvm' memory = '4096' name = 'winxp' disk = [ 'phy:/dev/sdb1,ioemu:hda,w', 'file:/root/xp.iso,ioemu:hdc:cdrom,r' ] vif = [ 'type=ioemu, bridge=eth0' ] device_model = '/usr/lib64/xen-default/bin/qemu-dm' #memmap = '/usr/lib/xen/boot/mem-map.sxp' vcpus=2 boot='c' usbdevice='tablet' sdl=0 vnc=1 vncviewer=1 on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' acpi = 1 apic = 1 keymap = 'fr' guest_os_type='windows' serial='pty' The Xen GPL Driver is setup. I don't found solution on Google to resolv this problem. I have the same problem on several different server.
