The function xrange() was renamed to range() in Python 3. Use "from six.moves import range" to get xrange() on Python 2 and range() on Python 3 as the name "range", and replace "xrange()" with "range()". The import is omitted for small ranges (1024 items or less). This patch was generated by the following tool (revision 0c1d096b3903) with the "xrange" operation: https://bitbucket.org/haypo/misc/src/tip/python/sixer.py Manual change: * Replace range(n) with list(range(n)) in a loop of nova/virt/libvirt/driver.py which uses list.pop() Blueprint nova-python3 Change-Id: Iceda35cace04cc8ddc6adbd59df4613b22b39793
