Re: [PATCH qemu 0/1] MAC address falls to permanent

[Влад Мао]

I cannot say for sure, but e1000 does not have this behavior, vmxnet3
in vmware also does not behave this way.
In addition, the address gets there only after a reboot, it does not
get there during normal operation, as you can see from logs i
attached. It seems to me that this is not quite the expected behavior,
isn't it?
