VM paused because of IO error is an expected behavior.
And could you please describe the vm/vmi events to check when it started to pause

Comment 4 Yan Du 2023-06-28 12:20:51 UTC

Are you able to resume the VM after paused by virtctl or UI? we need to understand why the IO error from the storage

By the way, the image size issue suggests another test:

Boot the VM without configuration changes but increase the image size to a multiple of 4,096 bytes first (e.g. "truncate %4096 /path/to/disk0/disk.img").

If the guest runs successfully with just the image size change, then we can be fairly sure the issue is caused by the image size.

Maybe some component should print a warning if the disk image is not a multiple of at least 512 bytes.
