# This script is executed in the CT0 context after moving
# PCI devices into or out of CT (vzctl set $CTID --pci_add/--pci_del).
# It is supposed to take care about actions needed to properly
# add/remove certain PCI devices.
#
# Parameters are passed in environment variables:
#   VEID	- container ID
#   VE_ROOT	- container root directory
#   PCI		- list of PCI devices
#   ADD		- boolean flag (1 - add, 0 - del)
