Just code motion. In theory we could also add earlyprintk=ttyS0,115200 on x86, but I cannot get it to work. --- src/launch.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) diff --git a/src/launch.c b/src/launch.c index 074ac6f..886041a 100644 --- a/src/launch.c +++ b/src/launch.c @@ -303,6 +303,12 @@ guestfs_impl_config (guestfs_h *g, #define SERIAL_CONSOLE "console=ttyS0" #endif +#if defined(__aarch64__) +#define EARLYPRINTK " earlyprintk=pl011,0x9000000" +#else +#define EARLYPRINTK ""...

Using the quiet option (when not in verbose mode) improves boot speeds by rather a lot, by avoiding sending messages over the slow emulated UART. Rich.

Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.

v1 was here: https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157 Not running the 'hwclock' command reduces boot times considerably. However I'm not sure if it is safe. See the question I posted on qemu-devel: http://thread.gmane.org/gmane.comp.emulators.qemu/402194 At the moment, about 50% of the time is consumed by SeaBIOS. Of this, about ⅓rd is SGABIOS
