[Xen-users] How secure is Dom0 from DomU

[Thomas King <tking@xxxxxxxxxx>]

Hi,

I would like to understand the security
implications between Dom0 and DomU. 

Dom0 = openSUSE 10.2
DomU = openSUSE 10.2 (paravirtualization)
DomU = openSUSE 10.2 (full virtualization)
DomU = WindowsXP (full virtualization)

If I must give out the DomU root (administrator)
passwords, how secure is the Dom0? Is there a difference in the security
between Full and Para virtualization? Can wrapping this in something like
AppArmour resolve some of the security issues (if there are any?) 

Thanks
Thomas
