事象
RHEL8(確か8.0)をインストールして、仮想化を有効にした後、virt-installを実行したとき、「ERROR Host does not support any virtualization options」みたいなエラーが起きることがありました。

# virt-install --name test [...] ERROR Host does not support any virtualization options. |
libvirtの状態を確認すると、何やら「Failed to …」というメッセージがいくつか出ています。

対処法
ぐぐってみると、以下のBugzillaにたどり着きました。
これを読んで、libgcryptをupdateすると、virt-installが動くようになりました。
