[pve-devel] [PATCH qemu-server 0/3] fix #2100 & #1807: offline migrate and

[Mira Limbeck]

The first patch contains the creation of the cloudinit disk if it does
not exist on startup. This patch is a prerequisite for the following 2.
As the size for the disk is fixed a sensible default for snippets files
was chosen (1MiB per file, 3 files max (meta, network, user)). This
should always be enough to still fit in the 4MiB limit.

Patch 1 fixes #1807 but there's still the issue with unmapped vmid on
restore. This is fixed in the 3rd one.

Patch 2 fixes #2100 by simply ignoring the cloudinit drive because it
always gets regenerated on vm start. For a VM to start after migration
the disk has to be created on the new host (this is done by patch 1).

Patch 3 changes the VMID of the cloudinit disk on restore and also
takes into account the targetstorage specified.

Tested with and without snippets and a Ubuntu 18.10 VM.

Mira Limbeck (3):
  cloudinit: create disk if it does not exist on start
  fix #2100: ignore cloudinit drive on offline migration
  map vmid correctly for cloudinit on restore
