qemu guesses via probing the format of root FS, but gives a warning and restricts write operations on block 0. Fix it by setting correctly the format as raw for more machines and non-KVM machines. In some cases, replaced the way machine disk is set for qemu. Fix for [YOCTO #7918] (From OE-Core rev: 6f7144ebe2da4c72ef58280e034b2cc75331a471) Signed-off-by: Cristian Iorga <cristian.iorga@intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
