Hello,
If You want really to deliver the best performace, is it the issue
to pay some hundreds of USD for the PV Windows drivers? I think this could
be not so huge invest if somebody really wants to get the best
performance...
How heavy load do You plan to have on Windows machines, which kind
of services do You want to have there?
Also I have to note - there is a significant difference between the
DomU started from the file and started from the block device, especially if
You have no problem to dedicate a direct physical device to the DomU and not
need the flexibility of LVM...
We have some ORACLE servers runing on Windows in DomUs with w2k
32bit and w2k3 64bit, there is a small count of the clients but make really
performance-intensive operations on the oracle servers, the servers are
running together with other instances and this is at least OK for us... At
least if You can arrange it so the virtual servers do not share the same
physical disk..
With best regards
Archie

Hi,
I think there is no optimazation method available for using windows with
xen. The only thing which i heard is, that microsoft will do something
for xen users. But I dont know when or what the consequences of the
project will be. Maybe special windows versions or only some
drivers..goodness knows :).
