I have not tried Centos6 VMs. The customer reported that he deployed Centos7 to the baremetal blades and saw, in ping traffic that incoming packets were vlan 0 tagged.
Then he deployed Centos6 to two baremetal blades and, in a ping test, did not see any vlan tags. If this is true, it suggests Ubuntu 18.04 and Centos 7 either add the vlan 0 tag or fail to remove it (if it's added by something else). Conversely, Centos 6 either doesn't add the tag or succeeds in removing it. I did not ask the customer to replicate the scenario of a kvm instance PXE booting on top of the Centos deployment from a DHCP server on a different blade. And I do not have access to test that scenario myself. Another test I'd like to see the results of are ping tests between Ubuntu 18.04 and Centos 6 -- to see which side, if any, sees the vlan 0 tag. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1805920 Title: iPXE ignores vlan 0 traffic To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1805920/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
