Ubuntu VM102 startup recovery (2026-11-09)

Observed:
- VM status was running but qmpstatus=io-error.
- QEMU guest agent was unavailable and box-to-guest route was down.
- PVE block statistics showed one historical failed write operation.

Recovery:
- Sent QMP resume through the PVE API.
- Resume task completed OK; no VM reboot, disk change, or config change.

Verified after resume:
- qmpstatus=running
- QEMU guest agent responding (version 8.2.2)
- guest uptime 1 day 15:16
- GDM, Xorg, GNOME Shell running
- Sunshine running as /usr/bin/sunshine /home/test2/.config/sunshine/sunshine.conf
- guest dmesg showed normal EXT4 mount/remount; no new I/O or read-only error

Conclusion:
- The apparent startup failure was a paused QEMU state, not a broken Ubuntu boot configuration. Reconnect Moonlight now.
