Hi 

could you use somthing else then ioemu? i
don't think so, i haven't see any paravirtualized driver yet... and i'm
also waiting for that (i've get the same problems but with an old Linux
2.4 Kernel and older Oracle db ;-) )

Hello all.

What disk I/O speed Windows guest should get?
I runned benchmarks using Iometer at Windows server 2003 guest and got
terrible results , about 4-6 Mb/sec ( btw , same for disks i connected
using MS iscsi initiator and  SAMBA shares )
It is normal speed for Windows guest  or something wrong in my installation?
Guest and Iscsi target running on same machine .
