LXD 4.10 リリースのお知らせ

8th of January 2021


LXD チームは LXD 4.10 のリリースをお知らせできることにとてもワクワクしています!

このリリースは軽めのリリースです。それは、LXD チームは 12 月 18 日から 1 月 4 日までお休みをいただいていたためです。しかし、多くのバグフィックスといくつか新しい改良が行われました。



ネットワークの状態表示内の VLAN 情報

ボンディングやブリッジの情報のように、新たに VLAN 構造をネットワーク状態のエンドポイントに追加しました。これは下位デバイスとインターフェースの VLAN ID を表示します。

root@abydos:~# lxc query /1.0/networks/bond-sw01.100/state
    "addresses": [],
    "bond": null,
    "bridge": null,
    "counters": {
        "bytes_received": 213651991756,
        "bytes_sent": 42453202,
        "packets_received": 97607519,
        "packets_sent": 431818
    "hwaddr": "0a:0f:7c:6e:db:d9",
    "mtu": 1500,
    "state": "up",
    "type": "broadcast",
    "vlan": {
        "lower_device": "bond-sw01",
        "vid": 100

VM のプロキシーデバイスのサポート(NAT のみ)

仮想マシンで proxy デバイスが使えるようになりました。
これは NAT モード(nat=true)でのみ機能するので、両サイドで同じプロトコルを使う必要があります。


ブリッジネットワークインターフェースに新たに security.port_isolation を追加しました。これによりインターフェース間の通信を制限できるようになりました。


イメージプロパティへのアクセス、設定、解除のために、新たに lxc image コマンドに 3 つの新しいサブコマンドを追加しました。

  • lxc image get-property
  • lxc image set-property
  • lxc image unset-property


stgraber@castiana:~$ lxc image get-property 305db7054652 os
stgraber@castiana:~$ lxc image set-property 305db7054652 foo bar
stgraber@castiana:~$ lxc image get-property 305db7054652 foo
stgraber@castiana:~$ lxc image unset-property 305db7054652 foo

VM 内のマルチキューネットワーキング

仮想マシン上のネットワークインターフェースは、仮想マシンに割り当てられた仮想 CPU の数と一致するように RX キューおよび TX キューの数を自動的に設定するようになりました。
