Re: [Libguestfs] [PATCH] lib: direct: Remove use of sga

sga (or "sgabios" or "Serial Graphics Adapter")
is an option ROM for
seabios which directs output to the serial adapter. This is very
useful for debugging BIOS problems during boot.
RHEL wants to deprecate this feature (in fact, they just deprecated it
without telling us). However there is an equivalent feature now in
seabios which can be enabled using either -nographic or
-machine graphics=off
FWIW, this is available since SeaBIOS 1.11, bundled with
QEMU 2.11.0 which is the minimum libvirt supports these
days. I presume libguestfs min version exceeds that ?
This commit removes sga and enables -machine graphics=off in the
direct backend.
(We cannot do the same for the libvirt backend because libvirt has no
feature to implement this yet).
You likely won't need any changes to libvirt side. Once I fully confirm
that it has no impact on live migration, we'll transparentely update
libvirt to use the new syntax.
