[pve-devel] [PATCH storage v3 02/10] plugin: dir: implement import content type
Dominik Csapak
d.csapak at proxmox.com
Mon Apr 29 13:21:03 CEST 2024
in DirPlugin and not Plugin (because of cyclic dependency of
Plugin -> OVF -> Storage -> Plugin otherwise)
only ovf is currently supported (though ova will be shown in import
listing), expects the files to not be in a subdir, and adjacent to the
ovf file.
listed will be all ovf/qcow2/raw/vmdk files.
ovf because it can be imported, and the rest because they can be used
in the 'import-from' part of qemu-server.
