Hi there,
I am using flowvisor to allow multiple users handle different portion of
traffic in a network of 3 OVS switches and bunch of VMs.
This is how I am adding flowspace:
fvctl add-flowspace dpid2-flow1 2 100 nw_src=10.0.0.3,nw_dst=10.0.0.43
slice1=5
fvctl add-flowspace dpid2-flow2 2 100 nw_src=10.0.0.43,nw_dst=10.0.0.3
slice1=5
fvctl add-flowspace dpid2-flow3 2 100 nw_src=10.0.0.4,nw_dst=10.0.0.44
slice2=5
fvctl add-flowspace dpid2-flow4 2 100 nw_src=10.0.0.44,nw_dst=10.0.0.4
slice2=5
fvctl add-flowspace dpid2-flow5 2 100 nw_src=10.0.0.5,nw_dst=10.0.0.45
slice3=5
fvctl add-flowspace dpid2-flow6 2 100 nw_src=10.0.0.45,nw_dst=10.0.0.5
slice3=5
fvctl add-flowspace dpid3-flow1 3 100 nw_src=10.0.0.3,nw_dst=10.0.0.43
slice1=5
fvctl add-flowspace dpid3-flow2 3 100 nw_src=10.0.0.43,nw_dst=10.0.0.3
slice1=5
fvctl add-flowspace dpid3-flow3 3 100 nw_src=10.0.0.4,nw_dst=10.0.0.44
slice2=5
fvctl add-flowspace dpid3-flow4 3 100 nw_src=10.0.0.44,nw_dst=10.0.0.4
slice2=5
fvctl add-flowspace dpid3-flow5 3 100 nw_src=10.0.0.5,nw_dst=10.0.0.45
slice3=5
fvctl add-flowspace dpid3-flow6 3 100 nw_src=10.0.0.45,nw_dst=10.0.0.5
slice3=5
fvctl add-flowspace dpid1-flow1 1 100 nw_src=10.0.0.3,nw_dst=10.0.0.43
slice1=5
fvctl add-flowspace dpid1-flow2 1 100 nw_src=10.0.0.43,nw_dst=10.0.0.3
slice1=5
fvctl add-flowspace dpid1-flow3 1 100 nw_src=10.0.0.4,nw_dst=10.0.0.44
slice2=5
fvctl add-flowspace dpid1-flow4 1 100 nw_src=10.0.0.44,nw_dst=10.0.0.4
slice2=5
fvctl add-flowspace dpid1-flow5 1 100 nw_src=10.0.0.5,nw_dst=10.0.0.45
slice3=5
fvctl add-flowspace dpid1-flow6 1 100 nw_src=10.0.0.45,nw_dst=10.0.0.5
slice3=5
fvctl add-flowspace dpid1-monitor1 1 100 any monitor-slice1=2
fvctl add-flowspace dpid2-monitor1 2 100 any monitor-slice1=2
fvctl add-flowspace dpid3-monitor1 3 100 any monitor-slice1=2
Without last 3 flowspace, slice1, slice2 and slice3 completely able to
handle/add flow entries. But, with last 3 flow-entries I get following
errors in Flowvisor:

Any help is appreciated! Thanks!
