[pve-devel] [PATCH v3 qemu-server 1/1] vm_start: check if storages of volumes support content images

[Lorenz Stechauner <l.stechauner@proxmox.com>]

it is now necessary for storages to support the 'images' content in
order to start vms on them. all native storage plugins already
report the images content correctly.
