Provisioning downloaded every cloud image over SSH into
/var/lib/vz/template/netork-images, on the node's root filesystem. On a
small root that fills up and takes Proxmox down with it (netOrk #480).
When the node has an active storage with content type "import" (Proxmox
8.2+), Proxmox now does it itself: download-url with checksum
verification into that storage, then import-from as the root disk. The
file is named after a hash of the full URL and reused when present.
Proxmox takes the format from the extension and has no ".img", so
Ubuntu's qcow2 .img is stored as .qcow2 -- a wrong guess fails at import
instead of attaching a qcow2 container as a raw disk.
Without an import storage, or for an image type Proxmox cannot import,
the SSH download is used as before.
get_vm_snapshots, create_vm_snapshot, delete_vm_snapshot and
rollback_vm_snapshot for VMs and containers, so netOrk's snapshot view
works on Proxmox as it does on VMware. Proxmox lists the live state as a
pseudo-snapshot named "current"; it is never reported or addressable.
Containers have no RAM state, so include_memory is ignored for them.
reboot_host() restarts the node with POST /nodes/{node}/status
command=reboot instead of /sbin/reboot over SSH.
start_vm, stop_vm, reboot_vm, suspend_vm and get_vm_config existed only
as declarations. netOrk called Proxmox's own power_vm and read a VM's
raw config through _node_api(), so no other hypervisor could serve the
same endpoints. These let netOrk talk to every hypervisor alike.
The power methods accept a VM's name or vmid, wait for the Proxmox task,
and raise ValueError/RuntimeError as the contract says instead of
returning a result dict. A forced reboot of a container is stop + start,
since LXC has no reset; suspending a container is refused. power_vm is
unchanged for existing callers.
get_vm_config moves the config parsing netOrk did in
_parse_proxmox_hw_config into the driver and returns a VMConfigDict:
disks with storage and size, NICs with model, MAC, bridge and VLAN, CPU
topology, firmware, machine type and PCI/USB passthrough.
get_vms reports vmid as a string ("100"), following
napalm-device-types 2.0, still ordered numerically.
