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.
