[SOLVED] VM fails to start occasionally

[prahjister]

Looking for some help with vm's and why they occasionally wont start. 1 core stays pegged and I will have to force stop and start the vm a few times. Uploaded config.

If I missed some diagnostic information please let me know. The logs I can see aren't very helpful. Any help is appreciated. I believe it a usb issue but I don't know how to confirm.

I was right...I found the culprit. It turned out to be a cheapo hub causing the issues. It is really weird that it worked for so long with no issues and only sporadically has issues now.
