VM keeps getting terminated by libvirtd

[Mobius71]

So I powered down and unplugged my server to do some light dusting and whatnot. Powered it back on and now I'm getting the following when trying to start up my Win 10 VM:

 

2024-02-26T15:14:34.876523Z qemu-system-x86_64: terminating on signal 15 from pid 15338 (/usr/sbin/libvirtd)
2024-02-26 15:14:36.404+0000: shutting down, reason=shutdown

 

Here's my xml:

It will look like it's starting up, but after about a minute it'll shutdown. I've tried checking all the VM settings, device groups for passthrough, the libvirt log as well, but it's always blank, even after I turned debug logging on.  Is my libvirt img jacked up maybe?  I'm kinda at the end of what to do on this and all the google results have also led me to dead ends.  I've attached diagnostics. Any help would be appreciated.

I cannot anything to say what is stopping the VM, do you have any backups running that may shutdown the VM or any processes running in the VM?

[Mobius71]

The VM can't run at all so not processes running in the VM.  Nothing new was introduced into the VM prior to system shutdown and it was previously starting reliably every time. Also no backups running that would affect the VM as far as I see.

So I somehow fixed this, but I'm not 100% sure how.  Just to document for anyone else that runs into this, I went in and changed a few things to try and pinpoint the issue (process of elimination).  I changed the ram allocation down a few GBs and also noticed I could change machine from i440fx-7.1 to 7.2 (it was previously set at i440fx-7.1 and had worked without issue, but figured, eh why not).  I also saw that the disk target bus for the VM image was set to virtio instead of sata so I changed that to sata (it was previously set to sata, but I changed it at some point while trying to make the VM start).  As the VM works, I didn't want to muck about with it anymore so again, not sure, but as of now all is well.
