The idea with #VE is that it converts the EPT violation to a specific in-guest interrupt. Interrupts are handled by the kernel, so you will need a kernel module that is handling that interrupt. Also, you can take a look at the xen-privcmd kernel module in the Linux kernel to get an idea on how to issue hypercalls.
