Sorry, I didn't see this email before now.
Unfortunately these qemu errors are very opaque. EINVAL could
indicate a whole host of problems with the disk, perhaps an invalid
format, disk corruption, or some backing file not being readable.
There is some effort upstream to get qemu to print better error
messages.
