I agree that C3 would be a problem - both guest and host.

However, for C4 I have a "installer hack" that allows C4 to install
under Xen (FC6 host) using virt-manager & kickstart.  When it's
finished, the only package that is modified is the kernel (to provide a
domU image).

Perhaps your VM is the issue with tls.  Once I started using a recent
enough host (FC6) and a recent enough guest (C4), all my tls problems
disappeared.  Even SELinux, which was always problematic for me under
UML, seems to be working smoothly now.

If someone wants a Xen C4 guest image, let me know, it only takes a few
minutes to create.
