10:39 a.m.
Remove the -bootloader option from the QEMU driver, for
https://bugzilla.redhat.com/show_bug.cgi?id=1176050
as it was only supported by xenner.
Remove the -domid option, also xenner-only.
Cleanup -boot command line generation.
Ján Tomko (5):
Remove bootloader option from QEMU
Remove code handling the QEMU_CAPS_DOMID capability
Make -boot arg generation more readable
Rename boot_buf to boot_opts
Use virBufferTrim when generating boot options

New subject: [libvirt] [PATCH 3/5] Make -boot arg generation more readable
If we combine the boot order on the command line with other
boot options, we prepend order= in front of it.
Instead of checking if the number of added arguments is between
0 and 2, separate the buffers for boot order and options
and prepend boot order only if both buffers are not empty.

^^^
Since the only place to add items is inside the "if (!emitBootindex)",
then this check can move inside the if statement.
Probably could move the other boot_order stuff inside here too including
setting the boot_order_str...
You could then go back to just one boot_buf, but I see in patch 4 & 5
you rename boot_buf... this is fine, just was typing and thinking as
usual...
if (def->os.bootmenu) {
if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_BOOT_MENU)) {
if (boot_nparams++)
^^ This one cannot happen...
Although I see in patch 5 it gets removed anyway...
