I've noticed this problem in Kimchi's error output: rc: 1 error: ovs-vsctl: no bridge named \nbr0 returned from cmd: /bin/ovs-vsctl --oneline list-ports \nbr0 Error listing OVS bridge ports for \nbr0 This patch fixes that by: - removing --oneline usage from ovs command; - using list comprehensions to split() each string in the list.
