Can you post your udev rules/scripts for virtual block devices? Thanks.
Uhm, well, the above was with a older xen-unstable which hasn't the
hotplug-ified setup for disks yet.
Attached below is my current setup, running flawlessly with a fresh
checkout. The rules file goes to /etc/udev/rules.d, the xen-* shell
scripts to /sbin. No dependency on hotplug any more, everything is
invoked directly via udev (or udevd), so this should create much less
trouble than the xen-hotplug.agent stuff.
cheers & enjoy
