It is not possible to use both a VLAN-aware bridge and a Linux VLAN bridge on a single physical NIC.

上記のようにシステムを構成し、2つの方法をテストしました。具体的には、nic_1上にLinux VLAN nic_1.10、nic_1.20、nic_1.30を作成し、これらのLinux VLANをLinuxブリッジのブリッジポートで定義し、Linuxブリッジ(VLANxx)を使用してVMを構成する方法、およびnic_1上にVLAN対応ブリッジを定義し、VM上にVLANタグを構成する方法です。

Linux VLAN上でのこのタグ解除方法は、何の問題もなく機能します。

VMを使用したこのタグ解除方法では、同一セグメント内での通信すら許可されなかった。

原因を調査する中で、2つの方法は1つの物理NIC上で同時に使用できないことが分かりました。
VLAN対応ブリッジのブリッジポートとして指定されている物理NICを変更するか、Linux VLANを利用する方法で使用されているLinuxブリッジを削除すると、システムが正しく動作することがわかりました。

これはかなり奇妙だ。
これはバグでしょうか?それとも仕様でしょうか?
