RE: [Xen-users] WinXP cannot partition disk

["Rob van Oostveen" <rob@xxxxxxxxxxxxxxx>]

Mats, Mark,

I disabled selinux in /etc/selinux/config and all problems were gone.. the 
iso works (cdrom) and windows is able to partition and format the disk. 

I wonder what consequences this has on the overall security of the Xen host 
though.

Anyway, I can continue installing and testing with Xen. Thank you for your 
time and effort! You've been a great help.

Best regards,
Rob
