My development VM became quite slow because some kswapd0 (if I remember correctly) running at 100% all the time.

I have my machine usually running 24/7, but I decided to restart to see if this helps (after increasing assigned memory).

After I restarted the machine I wasn't able to start any app for this VM.
I modified the template quite a lot since I restarted last time, so I wasn't too surprised.

I tried creating a new VM based on the same debian-10 template and all went fine.

Then I went away and when I came back my PC showed the lock screen and was frozen (I had this a few times in the past already).
So I had to restart again.

After this I couldn't start any application in the new VM as well.
I tried to start Gnome Terminal from dom0:terminal but nothing happens. No error. The command just hangs until Ctrl-c.

I couldn't find any log file with hints about possible causes.

I can run the VM in debug mode and access the data from the tiny terminal window.

Any ideas how to debug?

It looks like it was some code for keyring I added to `~/.profile`  that asked for a password.
I commented out that line and now it's working again.

What about this: Open a text terminal in the VM running "top" and sort the
output by "virtual size" (biggest on top). Watch who's growing and kill it ;-)
