[pve-devel] [PATCH storage/qemu-server/manager v6] implement ova/ovf import for file based storages

[Daniel Herzig]

I've just tested this series with the following images:

+ GNS3 with VMware ESXi image from https://www.gns3.com/software/download-vm,
unzipped and uploaded to local dir storage.
+ Ubuntu Noble from https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.ova,
downloaded straight through the 'Download from URL' button.

GNS3 imports nicely and runs.

Cannot really tell about noble -- it imports nicely
but will get stuck during startup with default settings
(~btrfs loaded, zoned=yes, fsverity=yes~). Fiddling with
hardware settings tends to let it boot, but I haven't yet managed to
provide it with a username and password that I'd know.

Best,
Daniel

Things that I've encountered:
+ Download from URL does not support zipped images.
+ If I use a root-mounted nfs share as extraction storage, I yield a
(not having a clue where the chown comes from):
------------------------------------------------------------
extracting local:import/GNS3_VM.ova/GNS3_VM-disk1.vmdk
tar: GNS3_VM-disk1.vmdk: Cannot change ownership to uid 64, gid 64: Operation not permitted
tar: Exiting with failure status due to previous errors
TASK ERROR: unable to create VM 112 - error during extraction: command
'tar -x --force-local \
-C /mnt/pve/nfs/images/112/tmp_3017_112 -f /var/lib/vz/import/GNS3_VM.ova GNS3_VM-disk1.vmdk' failed: exit code 2 
------------------------------------------------------------
+ Although I understand the purpose, it did not feel very 'natural'
having to add the 'disk image' storage type to the local directory with
the .ova-file for a successful import.
