I am converting this to a Discussion since it is not a technical issue with the UTM app itself but rather an issue with your guest VM.

[kuestess]

@torarg I had this issue too which I think is caused by a kernel version mismatch between the installed kernel after update and the Image/initramfs used to boot the VM. Ultimately, I decided to build an EFI image which works flawlessly. This gist was helpful: https://gist.github.com/thalamus/561d028ff5b66310fac1224f3d023c12

@conath

Can we reopen this as an issue? I ran this process twice and can confirm that ArchLinux ARM image from UTM's gallery breaks after pacman -Syu. Therefore the issue is with this particular image.

[teenjuna]

To be less vague: network interface just disappears after pacman -Syu:

[root@alarm ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

[conath]

There is another discussion about what seems like the same issue. Do the posts there help you? #3392

[teenjuna]

So, I've tried copying /boot/Image.gz and /boot/initramfs-linux.img from an updated system into UTM's image directory (e.g. ...com.utmapp.UTM/Data/Documents/ArchLinux.utm). It did not work.

[conath]

@osy any ideas?
