Hi,

I’m using 3 servers with XEN and 2 San. Twice have Xen3.2 and Windows VM are OK with GPLPV drivers. One server have Xen-4.0 and I have a problem with Windows VM:

Windows VM have very poor write disk performance (3 MB/s) with GPLPV driver (I tried 0.9 and 0.11 versions). Read perf are ok (~200MB/s).

Without GPLPV driver, it’s more credible, but I’m not using the best of my VM without GPLPV…

 

Xen host is Debian 6, with kernel 2.6.32-5. I’m using AOE, with AOEtools in version 32 and aoe driver in version 76.

 

What can I do for that ?

 

Thanks

Stéphane
