Re: [Xen-users] Windows 2008 64 bits + gplpv driver = BSOD

[Olivier LAMBERT <lambert.olivier@xxxxxxxxx>]

Ok, so after disabling signature and reboot BEFORE installing GPLPV
drivers, it works.
But I've got a big perf. issue :
Before GPLPV, test with Crystal Disk Mark 2.2 :
Read 512K : 295 MB/s Write : 9.3 MB/s

After GPLPV :
Read 512K : 8.3 MB/s Write : 7.7 MB/s

Wow. It's really slower !

Furthermore, without or with GPLPV driver, when I reboot my guest, it
freezes on a black screen with blinking cursor, just after the
"Shutdown computer" message.
xm list show a "s" state, and xend log says :

Domain has shutdown: name=winpv id=61 reason=reboot.
[2009-12-14 16:22:24 20062] INFO (XendDomainInfo:2091) Preserving dead
domain winpv (61).

So it's dead, but why ?

Thanks for the help :)

Regards,


Olivier
