Can we test the other commands that support -p? And is anyone interested in adding -p support to more commands (there are several long-running commands that could use it but don't have it yet).

Yes, this concern is what stopped me from writing such a test for a long time. However, I think we really need a test case for it because apparently we tend to break this, and after some pondering I came to the conclusion that results should be consistent as long as we restrict it to a single image format (drivers may behave differently), which is not raw (that would expose filesystem-specific behaviour). With a qcow2-only case I think we should be fine as long as neither qcow2 nor qemu-img change their implementation. The other case that I would love to test is not specifying -p but sending SIGUSR1. I'm not sure how to do that in a consistent way, though. Perhaps something with blkdebug. > Can we test the other commands that support -p? And is anyone > interested in adding -p support to more commands (there are several > long-running commands that could use it but don't have it yet). Feel free to implement it. ;-) (Perhaps it would be easier after converting some qemu-img subcommands to use block jobs internally.) Kevin
