RE: [Xen-users] Release 0.9.5 of GPL PV Drivers for Windows
Hi James;
I've been following this thread. On the "format" issue I noticed in
Device Manager that the Disk Properties, Location, on the General tab
reads Bus Number 0, Target ID 0, Lun0 for both disks. From my
experience with iSCSI the Location information in device manage is
obtained from the initiator and is accurate. Does your driver reflect
this information correctly? If so having two LUN0's on the same Target
ID would certainly confuse Windows.
Thanks for looking into this issue and feel free to tell me to leave you
alone :-). I am, of course, available to help you test at any time.
Best Regards
Geoff

Well... obviously the PV drivers should be running much better than the
HVM devices. I'm trying to fix the 'format' problem that was described
recently at the moment. I'll re-visit the performance issues shortly. I
suspect that on some systems, windows hands out lots of unaligned
buffers which will slow things down drastically. I'll try and put some
monitoring to catch when this occurs excessively and log something in
the event log. At least then I'll be able to get some feedback on if
these event log messages appear when performance is bad.
Can you tell me what systems you've measured performance on? Are they
all 'bad'?

Just don't boot with /GPLPV. xenpci will still activate and shutdown
will still work, but you won't get the PV block or network drivers,
which is what you want in this case.
