The cluster-wide /storage endpoint lists every storage regardless of
its "nodes" restriction, so _find_default_image_storage (and the
snippet-storage lookup) could pick a storage not actually available on
the node the VM is being created on. On a real server this stranded a
freshly-created VM shell with no disk attached: "qm importdisk" failed
with "storage 'local-lvm' is not available on node 'pve-02'" after the
VM (VMID 103) already existed. Querying /nodes/{node}/storage instead
fixes this, since Proxmox itself only lists what's available there.
Also adds get_image_storages() and an optional storage= override on
create_vm_from_cloud_init, so callers aren't stuck with auto-detection.
Proxmox's /storage API omits the "enabled" key entirely for storages that
were never explicitly toggled, rather than defaulting it to 1 — it isn't
present-and-falsy, it's just absent. Both _find_default_image_storage and
the snippet-storage discovery treated storage.get("enabled") as truthy-check,
so every storage without an explicit "enabled": 1 was silently excluded.
Confirmed live against a real Proxmox test server: local-lvm, local-zfs, and
fast-zfs all had content=images with no "enabled" key at all, causing
create_vm_from_cloud_init to always fail with "No storage with
content='images' found" despite multiple valid storages existing. All prior
tests used "enabled": 1 explicitly in their fixtures, masking the bug.
Fix: storage.get("enabled", 1) != 0 — absent or truthy means enabled, only
an explicit 0 excludes it. 4 new regression tests, 28 total pass.
Replaces the template-clone flow with: create empty VM shell, download the
cloud image on the node (cached by filename, optional checksum verification),
qm importdisk, attach as scsi0. NIC config, snippet upload, ssh keys, disk
resize, and start remain unchanged (already generic).
New helpers: _run_node_command (strict SSH exec with custom timeout and
non-zero-exit detection, unlike the best-effort _exec_ssh_command),
_download_cloud_image (idempotent download + checksum check),
_find_default_image_storage (content=images discovery, mirrors the existing
snippet-storage discovery).
24 tests pass (10 new: _run_node_command x2, _download_cloud_image x4, plus
rewrites of the 4 existing create_vm_from_cloud_init tests for the new flow).
Filters _get_node_network() to bridge/OVSBridge types only (excludes physical
NICs, bonds), plus SDN vnets from _get_sdn_vnets(). vlan_aware: Linux bridge
reflects its bridge_vlan_aware config flag; OVS bridge always true; SDN vnet
always false (VLAN already fixed by the vnet's zone/tag).
4 new tests: bridge/vnet filtering, Linux bridge vlan_aware flag, OVS bridge
always vlan_aware, SDN vnet never vlan_aware. All 15 tests in the file pass.
- Replace fixed mgmt/capture dual-NIC parameters with generic nics list
- Loop over NICs to build net0, net1, ... config strings (access VLAN or trunk)
- Remove hardcoded 'ip link set eth1 up' Cloud-Init hack (caller responsibility)
- Add disk_resize_gb parameter for post-clone disk expansion (scsi0/virtio0/ide0/sata0)
- Make DHCP configuration per-NIC with sensible defaults (primary NIC only)
- Update docstrings and logging to reflect generic NIC architecture
