[pve-devel] [PATCH v2 qemu-server 0/2] cleanup and fix vm restore with cloudinit

[Mira Limbeck]

the first patch is a simple cleanup as we're introducing a third spot
where the cloudinit disk size is required in the 2nd patch. we now define one
constant that's used in all 3 spots. this means the 2nd patch requires
the first one to be applied.

the second patch is the actual fix for restoring vms with cloudinit
disks as those did not change the vmid to the new one.

v2:
  first patch: now introduces a constant instead of a variable
  second patch: cleanups as @Thomas suggested

the size in the second patch is required for vdisk_alloc. without that
function we don't get the correct volid to use for cloudinit. if we
specify a size of 0 or anything else, there will be 'file exists' (we
use a file size check with 0 == file does not exist and try to create it
in commit_cloudinit_disk) or other errors when starting the VM as the size
does not match.

other solutions like find_free_diskname and get_next_vm_diskname would
require additional logic to make it work with vm-$vmid-cloudinit as
name.

Mira Limbeck (2):
  introduce one global CLOUDINIT_DISK_SIZE constant
  map cloudinit disk to new vmid on restore
