[v6,05/36] multi-process: Refactor monitor functions out of vl.c

Commit Message

Elena Ufimtseva April 6, 2020, 9:40 a.m. UTC

From: Elena Ufimtseva <[e-mail]>

Some of the initialization helper functions w.r.t monitor
in vl.c are also used by the remote process. Therefore, these functions
are refactored into shared files that both QEMU & remote process
could use.
