We are probably getting a little off topic and should move this over a Proxmox thread.
Then address this issue.
I have run a HA OS VM in Proxmox for a couple of years now, I don’t have this issue. If it’s the HA logs files, not sure as you haven’t been specific, you can help to reduce the amount of logging by changing your recorder config in configuration.yaml to something like this (edit as you need).
recorder:
db_url: !secret maria_db
purge_keep_days: 7
include:
domains:
- sensor
- binary_sensor
- switch
- light
- device_tracker
- vacuum
- group
- input_boolean
- cover
- person
- counter
- timer
- climate
- lock
- fan
exclude:
event_types:
- service_removed
- service_executed
- platform_discovered
- homeassistant_start
- homeassistant_stop
- feedreader
- service_registered
- call_service
- component_loaded
- logbook_entry
- system_log_event
- automation_triggered
- script_started
- timer_out_of_sync
If it’s a logging issue in Proxmox, then do some reading up on that and look for a fix.
It would guess you have done something in error during this process if you are getting a boot loop. Trash the VM and start again. If you haven’t already, you could take a look here for some pointers.
