RE: Reboot on *DOM0* while/after installing GPLPV drivers

[John Hayward <john.hayward%wheaton.edu@localhost>]

For dom0 5.1.2 and xen 3.3.2 running windows7 64 bit and installing gplpv 
drivers:
1) installing just the pci drivers went just fine.

2) when adding the disk driver:
a) it crashed with blue screen
b) could restart but when running for just a bit it would also crash 

2b could be done a number of times and the place it would crash would vary.

My 64 bit version of xp seems fine.
I have not tried 32 bit version of xp.

Sorry for miss info - it turned out that in earlier verisons of xen (I think 
before 4.1) one needs to have the path to qemu-dm - once that was in place I 
was able to run winxp-64bit with sp2 (which looked like win2003) and install 
the gplpv drivers - Windows seemed to be confused about the "new hardware" and 
was asking for drivers but it finally figured out it had them.

I hope tomorrow to check win7 and xp 32 bit with sp3.

This is on a dom0 5.1.2 and xen 3.3.2

Manual seemed to indicate he was successful with a dom0 6.0 version so I might 
try to see if I can replicate that.

For what it is worth I tried to install winxpwithsp 3  on a dom0 5.1.2 - xen 
3.3.2 and could not even install windows.
