Guest can write to nvdimm. So it can update the kernel & reboot into
the new kernel without help from the host.

Implement support for booting from a PMEM region compatible with NVDIMM and
NFIT specifications.
The current implementation is still slow. When running a Linux guest on top of
QEMU in x86:
Using actual -kernel option:
QEMU startup time: .080
BIOS startup time: .060
Kernel setup time: .590
