What is the BSoD code?



If you are running the debug version of the driver, there should be
some

useful stuff in /var/log/xen/qemu-dm-<domu name>.log which could

debug the problem.

By the way James, can I simply test the effect of non-GPLPV drivers by
choowing the "other" option while booting (without /GPLPV)? Or should
I really
do a full uninstall?


It depends on what the problem is. With /NOGPLPV (you don't need /GPLPV
since version 0.10 - drivers are always active and you use /NOGPLPV to
disable) the xenvbd 'controller' still appears but doesn't enumerate any
disks, and the xennet adapter appears but with a cable disconnected
state (to allow configuring with IP address etc before rebooting), so it
doesn't disable the drivers completely.

James

I see, better uninstall them then.
Thx!!
