Networking 使用Terraform/KVM在CentOS 7上使用Cloud Init设置静态IP

在[FAILED]线路上花了大约5分钟才启动LSB:启动/关闭网络失败。正如我们所看到的,机器没有按照Cloud Init的请求分配ipc4地址
为什么我的静态IP地址没有分配?我还尝试了ens3
作为接口名,但没有成功
Terraformstest.tf
文件
cloudinit.cfg
网络服务日志
解决方法:不要将Cloud Init用于网络配置
目前我找到的唯一解决办法是禁用Cloud Init的网络部分,这意味着不呈现network.cfg
文件。相反,在网络接口
部分中设置静态IP可以:
resource "libvirt_domain" "centos" {
name = "centos"
memory = "1024"
vcpu = 4
cloudinit = libvirt_cloudinit_disk.cloudinit.id
network_interface {
network_id = libvirt_network.test_network.id
hostname = "centos"
addresses = ["10.18.3.2"]
}
# ...
}
我遇到了完全相同的情况,只要在配置文件中指定dhcp4或dhcp6,虚拟机就会尝试通过dhcp获取地址(即使值设置为false)
对我来说,解决方法是将dhcp4和dhcp6从配置文件中删除,在快速启动和静态网络配置到位的情况下,一切都按预期进行。我遇到了完全相同的情况,在配置文件中指定dhcp4或dhcp6将导致虚拟机尝试通过dhcp提取地址(即使该值设置为false。) 我的解决方法是将dhcp4和dhcp6从配置文件中删除,通过快速启动和静态网络配置,一切都按预期进行
