GSoC'20 Interested Student: Adding support to Jailhouse Hypervisor

[PRAKHAR BANSAL]

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]
<https://libvirt.org/git/?p=libvirt.git;a=tree;hb=HEAD> / src
<https://libvirt.org/git/?p=libvirt.git;a=tree;f=src;hb=HEAD> / driver.h
<https://libvirt.org/git/?p=libvirt.git;a=blob_plain;f=src/driver.h;hb=HEAD>
- 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,
