<br>
The arm64 kolla building job[1] will run containers while building kolla images.<br>
But we met the mtu mismatched issue[2] between container and vm. That<br>
makes network accessing very unstable or failed in containers.<br>
<br>
I wonder how this issue handled on x86 clouds? And how to fix such issue?<br>
