+Subject: fix two vf virtual machine has same mac address
+through 82599,hns3 physical network cart vf two virtual machine,
+two virtual machine have the same mac address.
+
+MACAddressPolicy=
+The policy by which the MAC address should be set. The available
+policies are:
+
+persistent
+If the hardware has a persistent MAC address, as most hardware should,
+and if it is used by the kernel, nothing is done. Otherwise, a new MAC
+address is generated which is guaranteed to be the same on every boot
+for the given machine and the given device, but which is otherwise random.
+This feature depends on ID_NET_NAME_* properties to exist for the link.
+On hardware where these properties are not set, the generation of a
+persistent MAC address will fail.
+
+
+random
+If the kernel is using a random MAC address, nothing is done. Otherwise,
+a new address is randomly generated each time the device appears,
+typically at boot. Either way, the random address will have the "unicast"
+and "locally administered" bits set.
+
+none
+Keeps the MAC address assigned by the kernel.
