[v9,0/6] tools: enable xenstore-stubdom to use 9pfs

Message

Jürgen Groß Feb. 29, 2024, 12:48 p.m. UTC

This series is adding 9pfs support to Xenstore-stubdom, enabling it
to do logging to a dom0 directory.

This is a prerequisite for the final goal to add live update support
to Xenstore-stubdom, as it enables the stubdom to store its state in
a dom0 file.
