Hello, thanks for answering Neil. I think Neil means the block devices ?
Neil can you show us how to verify if those devices are still running for the null domain ids? I also think its maybe just a timing problem, maybe they do not shut down always as they should.. We can give you surely access to such u box and you could have a look.. Mit freundlichen Grüßen Thomas Toka - Second Level Support - [logo_mail] IP-Projects GmbH & Co.

You could probably remove the (null) from the list by using "kill -9" on the qemu pids.
