Rebooting helps against this.

Do you issue xm block-detach commands? There is a known bug here that would cause such behaviour. If you are not doing this, I would be interested to know, because that would be an unknown bug, and would be worth tracking down.

I see that behavior as well, after some time setting up block devices stops working (maybe network too, can't test that due to vbd not working and my domU's not booting any more). Restarting xend doesn't help. I don't use "xm block-*" commands.


Was this using udev or hotplug for dom0 device manipulation?
