Hi Jan,

Thanks for the reply. I looked deeper into the libvirt and Jailhouse source code and found following two things that seem relevant to the project I am interested in.

- Libvirt driver interface at [libvirt.git] / src / driver.h

- Jailhouse tool, which is using the ioctl API of the Jailhouse, available at https://github.com/siemens/jailhouse/blob/master/tools/jailhouse.c.

With the help of the above two, it looks like, a libvirt driver for the Jailhouse can be implemented. Let me know if I am moving in the right direction so far.

I have been looking at the other libvirt driver implementations for hypervisors like HyperV and VMware to understand their implementation and learn from there.

Thanks & Regards,

Sure, go ahead. Depending on the scope of the question, libvirt might be
the better community to ask. Therefore, I'm adding its list to this thread.
