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.
