[SOLVED] Starting qemu guest always leads to errors

[Proximate]

I installed the qemu guest on centos 8 servers that I migrated from esx to proxmox.
When rebooting the system, the service seems to start or at least status shows active.

However, if I stop it and try to start it, it never works and this is on every centos machine I migrated. I looked online and still am searching but cannot seem to find an answer. Hoping for some leads by posting this.

I found this and working through other posts.
https://forum.proxmox.com/threads/dependency-failed-for-qemu-guest-agent.75797/

I followed this to enable the service but it won't come up.
I uninstalled it and re-installed it and rebooted.
The proxmox GUI still shows it as disabled.

I then stopped the vm completely and even used 'stop' to make sure.
I went back to the GUI, unckecked the qemu-agent enabled option, saved it then went back and set it to enabled again.
Then I re-started the vm and now it's on.

Strange combination of things to do I guess.
