FIlesystem corruption after every shutdown

[matthewcmead]

I am unable to find a way to cleanly stop the VM without it corrupting the ext4 filesystem in disk.img. I am using the default ubuntu setup as built with the makefile. I have tried:

• In the VM guest: sudo shutdown -h now
• In the VM guest: sudo init 0
• From macOS host: vmctl stop ubuntu

All of these leave me with a disk.img that is corrupted. Eventually the corruption builds to the point that the system doesn't start properly. I have the Paragon extfs drivers for macOS, and I can perform the following in macOS:

hdiutil attach -nomount ubuntu/disk.img

After that if I verify the filesystem using the paragon extfs driver it says it needs to be repaired. I can repair it using the paragon extfs driver.

This happens after every shutdown, and from what I understand what I'm doing should exit the VM cleanly.

Can anyone shed light on this or recommend an approach that will prevent the VM from corrupting the ext4 filesystem?

Thanks!
