Three papercuts hit when creating a VM from the menu:
1. Disk size "30" was passed verbatim to qemu-img resize, which read it
as 30 BYTES and failed ("use --shrink"). The prompt now shows units
(e.g. 30G, 1T) and a bare number is normalised to GB ("30" -> "30G"),
in the menu and in deploy_qemu.py itself.
2. The VM name is no longer required: leaving it blank uses the default
erplibre-<distro>-<version> (e.g. erplibre-ubuntu-2604). Distro and
version are now asked first so the default can be offered.
3. The menu ignored the deploy exit code and carried on to "wait for the
VM IP" even after a failure, hanging forever with the error scrolled
off. It now checks the return code and stops with a clear message.

Debian 13 (trixie) genericcloud dropped the BIOS/GRUB-pc bootloader, so
SeaBIOS looped forever on "Booting Debian GNU/Linux" and the install
never completed. Boot via UEFI (OVMF) by default: trixie boots, and
Ubuntu/Debian 12/Fedora keep working (verified Debian 13 and Ubuntu
24.04 end to end). Add a --bios opt-out for hosts without OVMF, and pull
the UEFI firmware (ovmf / edk2-ovmf) with the libvirt/QEMU stack. VM
deletion already removes the nvram (undefine --nvram).

When the exact osinfo id is missing from the local osinfo-db (e.g.
ubuntu26.04, fedora43/44), the fallback was detect=on,require=off, which
made virt-install fall back to "generic" and warn "VM performance may
suffer". Fall back instead to the latest KNOWN osinfo of the same distro
(ubuntu26.04 -> ubuntu25.10, fedora44 -> fedora42): proper virtio/OS
defaults, no warning. detect=on,require=off remains only if nothing of
the family is known.

Debian VMs came up with no configured user, no hostname and no SSH key,
so neither the console (erplibre/erplibre) nor SSH worked. Two causes,
found via the guest cloud-init.log:
1. The NoCloud seed was attached as a CD-ROM. Debian's initramfs does
not load the CD driver (sr_mod) at the init-local stage, so the
"cidata" volume was invisible and cloud-init fell back to an empty
DMI seed (Ubuntu tolerates the CD). Attach the seed as a read-only
virtio disk instead: virtio-blk is in the initramfs, the label is
seen immediately, and the user-data is applied. Works for Ubuntu too.
2. The user was added to group "admin", which does not exist on Debian
(it does on Ubuntu) -> useradd failed and the user was never created.
Use "sudo" (present on both) instead.
Validated end to end: Debian 12 and Ubuntu 24.04 both get the erplibre
user (in sudo), the hostname, console login erplibre/erplibre and SSH by
key.

Interim Ubuntu releases (24.10, 25.04) were removed from cloud-images
/current/ once EOL, so their image URL 404'd. Switch the Ubuntu image
URL to /releases/<version>/release/ubuntu-<version>-server-cloudimg-
<arch>.img, which stays available for every published release, and drop
the EOL interim versions from the catalogue (keep supported LTS + 25.10
+ 26.04).
Also:
- silence the "crypt is deprecated" DeprecationWarning (openssl fallback
already covers Python 3.13+);
- a 404 during download now reports "image not found (EOL/removed), pick
a supported LTS" instead of blaming connectivity;
- add a NoCloud network-config (DHCP on e*) to the seed.

cloud-init's package_update/package_upgrade forced apt to hit the distro
mirrors on first boot; on a slow or unreachable network that stalls
cloud-init and delays SSH availability. They are now off by default
(SSH is already present in the cloud images and enabled via runcmd);
--apt-update opts back in (and runs upgrade too unless --no-upgrade).

The Debian deploy appeared frozen: cloud.debian.org sent this host to an
unreachable mirror and urlretrieve had no timeout, so it hung forever;
worse, output was block-buffered under the todo pipe so nothing showed.
- Stream downloads via urlopen with a 30s per-operation timeout: a dead
mirror now fails fast instead of hanging.
- Try several Debian mirrors in order (cloud.debian.org, then two
acc.umu.se mirrors) — first responsive one wins.
- Reconfigure stdout to line-buffered in main() so headers and progress
appear live even when captured by the menu.
- Add openssh-server to the cloud-init packages and a runcmd enabling
ssh/sshd, so every VM (Debian genericcloud included) is SSH-reachable.
- Add a timeout to the SHA256SUMS fetch too.
Validated: debian-11 fails over from cloud.debian.org to gemmei and
completes; debian-12 downloads fully.

Generalise the deployer beyond Ubuntu with a distro registry and a new
--distro flag (ubuntu default, debian, fedora). Each distro keeps its
own codenames, osinfo ids and per-version minimum RAM/disk. Image URLs
are built per distro (Ubuntu current/, Debian latest/, Fedora resolved
from the release index since it has no "latest" link).
Add --list-images to print the whole catalogue with specs, exposed in
the todo menu ("List available images and specs"); the deploy/download
flows now prompt for the distro first.
Resilient osinfo: when the local osinfo-db does not know an id (e.g.
ubuntu26.04, fedora43+), fall back to virt-install detect=on,require=off
instead of failing. Ubuntu 26.04 (resolute) is now enabled.
Also: throttle the download progress to integer-percent steps (single
updating line on a TTY, at most 101 lines when captured by the menu),
and skip the spurious "network is already active" error by checking the
libvirt network state before net-start.

Replace the fixed 8192 MB / 4 vCPU / 20G defaults with the minimum
resources required by the chosen Ubuntu version (libosinfo/osinfo-db
values): 20.04 -> 2048 MB/5G, 22.04 -> 2048 MB/10G, 24.04+ -> 3072
MB/20G. --vcpus now defaults to 2. This stops a small host from being
starved by an oversized default (an 8 GB VM failed to allocate on a
6.7 GB host) and silences the libvirt "less than recommended" warning.
In the todo menu, leaving the RAM/vCPU/disk fields blank now means
"version minimum" (the flag is simply not passed) instead of forcing
8192/4/20G. Any explicit value still overrides. README regenerated.

The script previously required a manually supplied image path and only
installed the client tools, so a bare host aborted at virt-install with
a missing libvirt-sock. It now derives and downloads the Ubuntu cloud
image from --version, detects and installs the full libvirt+QEMU stack
(daemon and system emulator included) through the host package manager,
then enables libvirtd. Adds a --download-only mode, a hypervisor
preflight check, clean error messages instead of Python tracebacks, and
a bilingual usage guide (README).
