UTM quit unexpectedly...

[aethernet2040]

Dear all, First time user of Github here, so please be nice. I have purchased a new M1 Mac mini, which I have decided I want to use to run a virtualised Fedora (ARM) Server (36). Fedora is installed in UTM and runs. I have assigned it 2 CPU cores, 4GB RAM and 40GB of disk space. I logged in to it via the Safari web browser and did all the updates that were available. I have also got as far as installing Docker and installing Nextcloud within a docker container. I should point out at this stage that most of this process has taken a very long time, as I have no experience of Linux, VMs or the CLI before this week. The web GUI of the Fedora server tells me that I'm only using about 2% of the 2 CPUs at anytime.

The issue is that after a few hours (maybe more), I come back to the machine to discover that "UTM quit unexpectedly...." Under "de-bug log" below I have provided the report read-out from the Mac itself. Hopefully I have also attached the crash log correctly.

Obviously my plans were to have this server running 24/7, so I need to work out why I'm only getting several hours before UTM crashes. As I mentioned above, I am very new to this, so if you know the answer, then can I ask that you speak to me as if you're trying to explain it to a child. I won't take offence.

Many thanks A

Configuration

• UTM Version: 3.2.4 (58)
• OS Version: macOS Monterey 12.4
• Intel or Apple Silicon?: M1 (Mac Mini 9,1 16GB)

Is anybody out there able to advise me on this issue please? UTM keeps quitting unexpectedly and I am none the wiser as to why it keeps doing it. Thanks

The crash log you have attached reads to me like a crash caused by some kind of SwiftUI bug. This means it needs a future macOS update to get fixed, and UTM could be updated in the mean time to work around it.

@osy thoughts?
