Intermittent connectivity issues with Ubuntu guest

[fiore42]

Describe the issue
Since a week or so, my Ubuntu 22.04 guest has lost steady connectivity. To make things more weird, in my troubleshooting I tried to run an old snapshot and it works perfectly well. I used gpt for troubleshooting ideas. Tried two different wifi networks, generated a new MAC address, flush the ARP cache, check routing tables, checked iptables, checked ufw, all I could think of. The guest behaves as a computer with faulty connectivity where 90-95% of packets are lost, but sometimes few packets go through. An always-on ping shows that packets get lost, but sometimes a few packets go through.

The next test I wanted to try is to clone the disk and attach it to a newly created VM but I'm having issues (I opened a specific issue for that).

Configuration

• UTM Version: 4.3.5
• macOS Version: 14.0 (it was doing this before I updated. I just updated before rebooting the host to test if reboot had any effect. it didn't.)
• Mac Chip (Intel, M1, ...): M2

Crash log
If the app crashed, you need a crash log. To get your crash log, open Console.app, go to Crash Reports, and find the latest entry for either UTM, QEMU, QEMUHelper, or qemu-*. Right click and choose Reveal in Finder. Attach the report here.

Debug log
I attached both the logs of the bad VM and the good VM but I don't know what to look for

bad_debug.log
good_debug.log

After troubleshooting I found a zombie process called [wg-crypt-vpn] that kept changing PID. It seemed connected to the VPN hide.me - the only way I found to get rid of it was to move the folder /opt/hide.me/
