U opens "Package updates": the pending apt updates of every online node, with node, package, current and new version, origin and priority. A node that fails is shown as "<node>: unavailable", and the other nodes are still listed. A hint says the list is as of the node's last apt update; this call does not refresh it. The main frame's bottom border shows "· N package updates" after the backup count, with a singular for 1. The count is fetched on mount, after a context switch and whenever the updates screen loads, not on every guest reload, since it costs one CLI call per node. It uses the same generation guard as the guest list, so a count from the old cluster is dropped after a switch. Running apt update or upgrade stays out of scope; it is a write. Read-only live check: "mainframe · 23 package updates", and 23 rows in the screen. Closes #13 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

cv4pve-cli-tui
Textual TUI for cv4pve-cli: list Proxmox VE
guests (VMs and LXC), start/shutdown/stop/reboot them, and change cores, memory and
disk size. The table shows CPU % and Mem % of running guests and the info screen shows
in-use values (refresh with g).
It shells out to cv4pve-cli and uses its current context (cv4pve-cli config use <name>);
it stores no credentials itself. Tested with cv4pve-cli 2.4.0.
Run
uv run cv4pve-tui
| Key | Action |
|---|---|
s |
start |
S |
shutdown (confirm) |
x |
stop - hard power-off (confirm) |
r |
reboot (confirm) |
Enter |
info: resources (CPU, memory, swap, disks), backups, backup job, network (config and runtime IPs) |
Enter then e |
in info: edit cores / memory / grow a disk (disk growth asks again; it cannot be undone) |
Enter then b |
in info: backup now (snapshot, zstd, storage choice); a there = also show backups of earlier guests that had the same VMID |
Enter then n |
in info: edit network (bridge, VLAN, firewall, IPv4/IPv6; VM IP via cloud-init at next boot); u there = undo the last network change of this guest (this session only) |
Enter then p / R / D |
in info: take a snapshot (name, description, VM: include RAM) / roll back to the snapshot under the cursor (confirms; starts the guest again if it is running) / delete the snapshot under the cursor (confirms) |
t |
shell in a running LXC container (ssh -t root@<node> pct enter <vmid>) |
l |
tasks: recent cluster tasks (start, duration, node, type, VMID, user, status; ! marks failures); Enter shows the log of the task under the cursor, g reloads. In info: l = only this guest's tasks |
U |
package updates: pending updates per online node (node, package, current, new, origin, priority), read-only; g reloads. The list is as of the node's last apt update. The frame's bottom border shows the count |
g |
refresh |
c |
switch cv4pve-cli context (cluster) |
q |
quit |
Warning: link changes (bridge, VLAN, firewall) apply immediately on a running guest and can cut its network (and DNS for others if the guest is your DNS server). IP changes on a running container may need a reboot of the container (seen: static -> DHCP gave no IPv4 until a reboot).
The shell key needs key-based root SSH to the PVE node (LXC only).
Switching context runs cv4pve-cli config use, which changes cv4pve-cli's global current
context: other shells and scripts follow, and it stays after the app exits.
A ! in the first column marks a guest that no backup job covers (Proxmox's
not-backed-up list); the frame's bottom border shows how many.
Empty fields in the edit dialog are left unchanged. If a CPU/memory change cannot be hot-plugged, the app tells you it applies at the next reboot.
Development
uv sync
uv run pytest
uv run ruff check src tests && uv run ruff format --check src tests
Tests mock cv4pve-cli; they never touch a cluster. CI (.gitea/workflows/ci.yaml) runs
the same commands on every PR into main; ruff is pinned in the dev group so local runs
and CI check the same rules. Design: docs/plans/guest-tui-mvp.md.
