Re: [PATCH] qemu: Report error from both sides of migration

When migration fails in Perform phase, we call Finish on the destination host with cancelled=1 and get the error from there and report it to the user. This works well if the error on the destination caused the migration to fail. But in other cases the main error may reported by the source and the destination would just be complaining about broken migration stream. In other words, we don't really know which error caused the migration to fail and we have no way of detecting that. So instead of choosing one error, this patch will combine the error messages from both sides of migration into a single message and report it to the user. The result would be, for example: operation failed: migration failed. Message from the source host: operation failed: job 'migration out' failed: Certificate does not match the hostname ble.bla. Message from the destination host: operation failed: job 'migration in' failed: load of migration failed: Invalid argument And yes, this is ugly, but I wasn't able to come up with a better way of fixing this issue.
