Hello OpenBSD, I was trying to run Linux inside vmm, by converting an existing vmdk-image to qcow2 using qemu-img. While the configuration and setup seems to be straightforward, I had filesystem corruption issues on the ext4-fs inside the VM.
This happened on two separate occasions - in the first try I was booting from the cd iso-image and mounted the disk to enable serial console. As soon as I changed files on the mounted disk I got errors, unmounting and running fsck could not repair. The next try I booted the VM on a different machine, enabled serial console there, and then converted to qcow2. This time the machine did boot up once, but failed due to filesystem errors as soon processes started to write to the filesystem. I was not able to boot it again. When converting the same vmdk image to raw instead of qcow2 the VM did start up and run without issues. I am running OpenBSD 6.4. Are there known issues with qcow2 in vmm? Anything I can do to help understand/analyze the issue? Regards, Malte
