>From ovs-vswitchd man page:
ovs-vswitchd started through ovs-ctl(8) provides a
limit of 7500 file descriptors. The limits on the number of
bridges and ports is decided by the availability of file
descriptors. With the Linux kernel datapath, creation of
a single bridge consumes 3 file descriptors and adding a
port consumes 1 file descriptor. Performance will degrade
beyond 1,024 ports per bridge due to fixed hash table
sizing. Other platforms may have different limitations.
