Yes. In some cases.
There are cases where strict separation is not an issue, where
granting priviledges does not really matter.
And even where strict separation is an issue, with Xen there shouldn't
be any problem, should there?
I mean, with UML obviously if the kernel is compromised, it can access
everything the binary can on the host - and needs to be restricted
there somehow. And if compromising the kernel shouldn't be possible,
it gives quite a bit of restrictions on the guest side - like no
modules allowed and so.
But with Xen, the separation is on a lower layer, and there should be
no problem allowing custom built kernels with custom patches or binary
modules or whatnot.
But in any case, it is simply a choice there.
