+ vHost and QEMU v2.4.0+:
+ - For versions of QEMU v2.4.0 and later, it is currently not possible to
+ unbind more than one dpdkvhostuser port from the guest kernel driver
+ without causing the ovs-vswitchd process to crash. If this is a requirement
+ for your use case, it is recommended either to use a version of QEMU
+ between v2.2.0 and v2.3.1 (inclusive), or alternatively, to apply the
+ following patch to DPDK and rebuild:
+ http://dpdk.org/dev/patchwork/patch/7736/
+ This problem will likely be resolved in Open vSwitch at a later date, when
+ the next release of DPDK (which includes the above patch) is available and
+ integrated into OVS.
