Functionality-wise no downsides, but there is a potential security issue in that if pygrub is exploited, an attacker could run arbitrary code on dom0. The preferred alternative to pygrub is PV-grub, which is a small PV domain (a stub domain) that just has grub in it only and can be used as a secure grub bootloader. > It allows the guest to run its own unique kernel (read: doesn't > need to be the same as dom0) and then each guest can truly act like a > seperate machine. > > On 23/06/2011 14:31, Mike Fröhner wrote: >> >> Hey Wiebe, >> >> well in configfile of domU u are able to configure a kernel.
