[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] PATCH: 1/10: Add a QEMU machine type for fullvirt guests
This patch does a (no functional change) re-arrangement of the code for starting
up a fully virtualized guest. In particular it creates a new QEMU machine type
for Xen fullyvirt guests which can be specified with '-M xenfv'. For
compatability
this is in fact made to be the default. The code for setting up memory maps is
moved out of vl.c, and into hw/xen_machine_fv.c. This is basically to ensure
that
it can be easily skipped when we add a paravirt machine type in the next patch.
