[pve-devel] [PATCH qemu-server 1/2] fix #3010: add 'bootorder' parameter for better control of boot devices
Stefan Reiter
s.reiter at proxmox.com
Thu Sep 24 16:11:41 CEST 2020
(also fixes #3011)
Deprecates the old 'boot' and 'bootdisk' options (they still work the
same, but will get removed if a user sets a 'bootorder' parameter and
ignored if both are set).
This allows a user to specify more than one disk in the boot order,
helping with newer versions of SeaBIOS/OVMF where disks without a
bootindex won't be initialized at all (breaks soft-raid and some LVM
setups).
This also allows specifying a bootindex for USB and hostpci devices,
which was not possible before. Floppy boot support is not supported in
the new model, but I doubt that will be a problem (AFAICT we can't even
attach floppy disks to a VM?).
Default behaviour is intended to stay the same, i.e. while new VMs will
receive the new 'bootorder' property, it will be set so the VM starts
the same as before (see get_default_bootorder).
The API is updated to handle the deprecation correctly, i.e. when
updating the 'bootorder' attribute, the old properties are removed
(would now be useless). When removing a device that is in the bootorder
list, it will be removed from the aforementioned. Note that non-existing
devices in the list will not cause an error - they will simply be
ignored - but it's still nice to not have them in there.
Includes a cfg2cmd test.

The diff of the network part in config_to_command looks a bit weird, that's
because the indentation was off by one in the entire block.
