Hello I have a real problem with the performance of my Windows XP Pro on HVM I''m using Debian Lenny with Xen 3.2 and the kernel 2.6.26-2-xen-amd64 The main problem is IO Disk. 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.

What is the brand and model of raid card being used? What disk performance do you get in Dom0?

If it shows QEMU disk then the PV drivers isn''t used. -- Fajar> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Kyeto> I have a real problem with the performance of my Windows XP Pro on HVM > I''m using Debian Lenny with Xen 3.2 and the kernel 2.6.26-2-xen-amd64 > > The main problem is IO Disk. > A test show that i have no more 6MB/s on a copy ..._______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Try removing ioemu from both lines. As I recall they would prevent GPLPV from working properly. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I''m using a software raid. I''m nearly 100Mo/s. Without ioemu, it''s the same thing. On the device manager, i see Xen SCSI, the driver is OK Writing on Dom0: dd if=/dev/zero of=/tmp/disk.img bs=1M count=5000 5000+0 enregistrements lus 5000+0 enregistrements écrits 5242880000 bytes (5,2 GB) copied, 56,5965 s, 92,6 MB/s Reading on Dom0 : dd if=/tmp/disk.img of=/dev/null 10240000+0 enregistrements lus 10240000+0 enregistrements écrits 5242880000 bytes (5,2 GB) copied, 25,1306 s, 209 MB/s Fajar A.
