If you boot the kernel on bare hardware, the Xen parts of the kernel
will basically be switched off, and play no part in runtime. All
hardware features and device drivers should be available as normal. I
run kvm on pvops/xen kernels all the time.
If you boot the kernel under Xen, then VT/SVM will not be available, and
any kernel module which tries to use them - like kvm or (I presume)
virtualbox - should quietly get out of the way. If they cause the
domain to crash, then that's a bug in those modules.
If by "the machine will reboot" you mean that the whole system crashes,
then that's definitely a bug in Xen which should be fixed. It should
never be possible for a domU to crash the system.
