I have the same error, I had 'hotplug-base' installed, just added
'hotplug' (these are gentoo ebuild names, hotplug-base installs
/sbin/hotplug and hotplug is /etc/hotplug scripts). It made no
difference, virtual block device still fails out. After a reboot
/proc/sys/kernel/hotplug points to /sbin/udevsend, I don't know what
it should be for xen to work?
