1. はじめに
- 適当なLinux環境から、vCenterにvirshで接続してVM一覧を取得してみた。
- 特に毎回ID/Passwordを指定するのは面倒なので、パスワードレスでの方法を確認した。
2. IDもパスワードも指定しない場合（IDもパスワードも聞かれる）
vCenter接続
# virsh -c vpx://vcsosv-vc.acs.japan.local/IBMCloud/vcs-osv-cluster/host-km000.acs.japan.local?no_verify=1 list --all
Enter username for vcsosv-vc.acs.japan.local [administrator@vsphere.local]:
Enter administrator@vsphere.local's password for vcsosv-vc.acs.japan.local:

Enter username for host-km000.acs.japan.local [root]:
Enter root's password for host-km000.acs.japan.local:

3. IDだけ指定した場合（パスワードが聞かれる）
- vCenter接続時は、
\をURLエンコードして、vsphere.local%5CAdministratorのように記述する必要がある。
vCenter接続
# virsh -c vpx://vsphere.local%5CAdministrator@vcsosv-vc.acs.japan.local/IBMCloud/vcs-osv-cluster/host-km000.acs.japan.local?no_verify=1 list --all
Enter vsphere.local\Administrator's password for vcsosv-vc.acs.japan.local:

5. IDもパスワードも指定せずにパスワードレス接続
/etc/libvirt/auth.confに以下のようにファイルを書いておく。
-
authセクション
- [auth-esx-ホスト名]もしくは[auth-esx-IPアドレス]の様式でセクションを記載する。credentialsには、このセクションが利用するcredentialsセクション名（任意の名前で良い）を記載する。
-
credentialsセクション
- [credentials-xxxx]のxxxxの箇所に、上記のauthセクションで指定したcredentials値を指定する。
- 接続ユーザ、パスワードを記載する。
/etc/libvirt/auth.conf

[auth-esx-host-km000.acs.japan.local]
