I am running Kubuntu 21.04, and the latest official version of virtualbox and whonix as of wrting.
This issue has been occuring the past 2 months or so, and I’ve been trying to diagnose it myself but when I have both the gateway and workstation (gateway-cli and workstation-xfce) running, it seems anywhere from 5 mins to an hour after launch and it’ll freeze the host. The mouse moves, but nothing is responsive within the vm, or host. I’ve let it sit for upwards to 30 minutes before and it never resumed. I’ve got swap disabled on my host, i did enable it for testing with no luck. Both gateway and workstation have 2GB ram allowed by virtualbox. I’ve tried with all default settings, then again with my custom settings. I’ve tried using on different hdd’s, and ssd’s. This January 2021, i switched to a new computer where I started sometime after notcing this where it didn’t occur on my last pc, however I’m not sure if this is just a conicidence or not, can’t test it now. My pc, if it helps is a Lenovo Legion 15-ARH05 released around mid 2020.
This issue doesn’t occur when using a windows 10 vm, which i’ve used for 3 hours straight for testing. So I do not believe it is over using system resources or a virtualbox bug.
I do not know how to check dmsg for any issues as they seem to get erased or reset every restart of linux, and I can’t check it when the host locks up on me (When it does a hard shutdown is needed).
Anyway to figure out whats going on?
