Hi together, i''m running a winxp hvm-domain without the GPLPV-driver. I imported an iscsi-target as a lun for the winxp-domain and run an iometer test directly on the winxp-domain: Blocksize type MB/sec ------------------------------ 1 MB read 25 MB 1 MB write 0.8 MB 128 kb read 25 MB 128 kb write 0.8 MB If I run the same test on the xen-domain0 (hostsystem)using iometer''s dynamo, I got Blocksize type MB/sec ------------------------------ 1 MB read 66 MB 1 MB write 55 MB My problem ist the 0.8MB/sec in the winxp-domain... Is there a way to track down the performance issue ?

Hi, Iometer have been installed from http://www.iometer.org/ under XP. Transfer request size to 1MB and 128k and measured. 1MB: Read: 35MB/s Write: 10MB/s 128k: Read: 21MB/s Write: 7,5MB7s I think that there is a problem with your setup. My setup uses a LVM Volume on Software Raid1 on two SATA Drives. XEN 3.2.1build from Source. But I have a problem with the load in dom0, when XP ist idle. The CPU in Xentop is nearly 100% all the time, in the xp dom. What is your cpu level of the HVM Domain. Thanks.

I hear that the network performance under HVM Windows is quite poor without the drivers. Perhaps you''re having network throughput problems in your VM?

Note that the GPLPV drivers are under development, so treat them as beta quality and bear in mind there may not be a smooth upgrade path. You could check out the mailing list archives in order to see what experiences other people have had and learn about any problems you might need to watch out for. The developers of the GPLPV drivers are very responsive regarding queries and bug reports.
