Does anyone know the problem with missing device nodes (like /dev/hda1) in domU? Must the device nodes used in domU exist in the dom0? What i have to do, when some device nodes are missing in domU?

After some time, xenbus seems to get stuck however, and then the hotplug events don''t seem to get through any longer. Rebooting helps against this.

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.

Restarting xend doesn''t help. I don''t use "xm block-*" commands. cheers, Gerd _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
