Hi Steven,

We tested the xm block-attach/detach command.
It repeats block-attach/detach command for DomU and pv-on-hvm on HVM Domain.
(block-attach -> block-detach -> block-attach -> block-detach -> ...)

The block-attach command failed when repeating 256 times.

I can't reproduce this - just tested 500 or so attach/detach pairs in a tight loop and worked for me. However I was using a regular domU - is it pv-on-hvm only? Can you give a more detailed repro case (or a script)?

We tested only pv-on-hvm. The script used when testing is appended. We will confirm it again with latest xen-unstable.hg.
Thanks,
