预期结果 #

host1虚拟机正常启动

环境信息 #

• Libvirt版本：

Compiled against library: libvirt 8.0.0
Using library: libvirt 8.0.0
Using API: QEMU 8.0.0
Running hypervisor: QEMU 6.2.0

• Vagrant版本：

Installed Version: 2.2.10
Latest Version: 2.2.19

• 系统版本：Ubuntu 22.04 LTS（Jammy）
• Vagrant插件版本：

vagrant-libvirt (0.9.0, global)
vagrant-vbguest (0.30.0, global)

已尝试操作 #

• 曾安装Ruby 3.0，现已移除，当前仅使用Vagrant内置Ruby 2.6.6
• 执行/opt/vagrant/embedded/bin/gem install rexml安装依赖，遇SSL证书验证错误，提示缺少GlobalSign Root CA - R3证书
• 更新系统证书，问题未解决

解决建议 #

方法1：绕过SSL验证安装rexml #

执行命令临时跳过SSL验证，直接安装依赖：

/opt/vagrant/embedded/bin/gem install rexml --no-verify-certificate

方法2：修复Vagrant内置Ruby的SSL证书 #

1. 复制系统CA证书到Vagrant证书目录：

sudo cp /etc/ssl/certs/GlobalSign_Root_CA_-_R3.pem /opt/vagrant/embedded/ssl/certs/

2. 更新证书索引：

cd /opt/vagrant/embedded/ssl/certs/
sudo c_rehash

3. 重新安装rexml：

/opt/vagrant/embedded/bin/gem install rexml

方法3：升级Vagrant版本 #

Vagrant 2.2.10版本较旧，升级到最新版本可修复部分依赖和SSL兼容问题，直接下载对应版本安装即可。

方法4：升级vagrant-libvirt插件 #

当前插件版本与Vagrant、Ubuntu环境可能存在兼容性问题，执行命令升级插件：

vagrant plugin update vagrant-libvirt
