# This is a bit ugly. udev passes us the USB bus number and
|
|
# device number with leading zeroes. E.g.:
|
|
# BUSNUM=001 DEVNUM=022
|
|
# This causes libvirt to assume that the numbers are octal.
|
|
# To work around this, we need to strip the leading zeroes.
|
|
# The easiest way is to ask bash to convert the numbers from
|
|
# base 10:
|
|
#
|
|
BUSNUM=$((10#$2))
|
|
DEVNUM=$((10#$3))
|
|
|
|
#
|
|
# Now we have all the information we need to update the VM.
|
|
# Run the appropriate virsh-command, and ask it to read the
|
|
# update XML from stdin.
