I was making a change to net-vm when I accidently added a usb controller to the devices list. I had clicked ok before I realized it and as soon as I did, I lost my keyboard and mouse control. net-vm does not auto-start, so I rebooted hoping I could change it back, however after I entered the boot password I saw the following text:
[FAILED] Failed unmounting boot-efi.mount - /boot/efi.
[FAILED] Failed unmounting boot-efi.mount - /boot/efi.
[FAILED] Failed unmounting boot.mount - /boot.
[ 83.255827] EXT4-fs error (device dm-4): ext4_check_bdev_write_error:224: comm systemd-journal: Error while async write back metadata

[ 84.884857] EXT4-fs (dm-4): Remounting filesystem read-only
The screen stays like this and nothing changes. Is there anything I can do to either fix the problem or recover the system? Thank you.
