Maybe /proc/sys/kernel/hotplug was meant. In this case I have to say, it is available, but empty:
cat /proc/sys/kernel/hotplug
shows nothing.

Obviously there is a problem with the hotplug system:
lnxt2:~ # cat /proc/kernel/sys/hotplug
cat: /proc/kernel/sys/hotplug: Datei oder Verzeichnis nicht gefunden or in english: file not found

Could you post the output of

2006/6/27, Norbert Wegener <nw@xxxxxx>:

I have a Suse10.1 system. When starting a domain with this config file nw1:

kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
memory = 64
name = "xen1"
vif = [ '' ]
disk =
['file:/home/rootfs,sda1,w','file:/home/swap,sda2,w','file:/home/homexen1,sda3,w']
root = "/dev/sda1 ro"
and
xm create nw1
Using config file "nw1".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
