HAOS VM helper script: issue + patch summary

Symptom

• Script aborts with: exit code 127: while executing command pv -N "Extracting" > "$FILE_IMG".
• Occurs during image decompression stage when creating the HAOS VM.

Environment

• Proxmox VE 9.x (Debian 13 base).
• HAOS image: haos_ova-16.1.qcow2.xz.
• Community script originally authored for PVE 8.1+ and (strictly) 9.0.

Root causes

1. Hard dependency on pv: Script unconditionally pipes xz -dc into pv, failing if pv is not installed.
2. Over‑strict version gate: pve_check rejects PVE 9.1+ even though the rest of the flow works on 9.x.
3. Fragile target path build: FILE_IMG was derived with a brittle parameter expansion which could misresolve the .qcow2 output path.

Patch

haos-vm.sh

1. Make pv optional:

   • Replace unconditional xz -dc "$CACHE_FILE" | pv -N Extracting > "$FILE_IMG" with:

   if command -v pv >/dev/null 2>&1; then
     xz -dc "$CACHE_FILE" | pv -N Extracting >"$FILE_IMG"
   else
     xz -dc "$CACHE_FILE" >"$FILE_IMG"
   fi

   • Also ensure xz-utils is present.

2. Relax PVE version check:

   • Accept PVE 8.x and 9.x instead of only 8.x and 9.0.

3. Reliable image path construction:

   • Compute names explicitly:

   FNAME="$(basename "$CACHE_FILE")"
   FILE_IMG="/var/lib/vz/template/tmp/${FNAME%.xz}"  # -> .qcow2

4. Preserve advanced options:

   • Keep user‑chosen VMID, q35, RAM/cores, MAC/bridge, cache mode.
   • When attaching the disk, include selected cache mode via ,${DISK_CACHE%*,}.

Commands you can run

Minimal manual fix to an existing script file yourscript.sh:

# Allow 9.x (example sed; adjust to your file):
sed -i 's/9\.0 (NOT 9\.1+)/9.x/g; s/if ((MINOR != 0)); then/if ((MINOR < 0 || MINOR > 9)); then/' yourscript.sh

# Robust FILE_IMG construction:
sed -i 's|FILE_IMG="/var/lib/vz/template/tmp/${CACHE_FILE##*/%.xz}"|FNAME="$(basename \"$CACHE_FILE\")"\nFILE_IMG="/var/lib/vz/template/tmp/${FNAME%.xz}"|' yourscript.sh

# Make pv optional around extraction:
sed -i 's|xz -dc \"$CACHE_FILE\" | pv -N \"Extracting\" >\"$FILE_IMG\"|if command -v pv >/dev/null 2>&1; then\n  xz -dc \"$CACHE_FILE\" | pv -N Extracting >\"$FILE_IMG\"\nelse\n  xz -dc \"$CACHE_FILE\" >\"$FILE_IMG\"\nfi|' yourscript.sh

Verification steps

1. Re‑run the script. Confirm:

   • Decompression completes and creates /var/lib/vz/template/tmp/haos_ova-16.1.qcow2.
   • qm disk import succeeds and reports an imported disk.
   • VM starts and HAOS console appears.

Risks / notes

• Future PVE minor changes could affect qm disk import vs qm importdisk. The patch autodetects and uses either.
• If storage is ZFS/thin LVM, imported format raw is fine; adjust if you require qcow2 on file storage.
• If your network needs VLAN/MTU, the advanced settings already support it.

Many AI Output. What excactly is the issue?

Only xz or pv is missing, its just an one liner on your host....
apt-get install -y xz-utils pv

extracktion faILES ON PVE 9 BUT I FIXED IT HOPED I COULD HELP THE NEXT PERSON

Working fine by my system's and a clean VM (Proxmox VM) ?
