OVN NAT只能配置到Gateway Router或Distributed Gateway Port上。 一个Router只能有一个Distributed Gateway Port. install vm 在两台机器上各安装两个虚拟机 rhel_version=rhel$(rpm -E %rhel) # libvirt && kvm yum -y install virt-install yum -y install libvirt yum install -y python3-lxml.x86_64 rpm -qa | grep qemu-kvm >/dev/null || yum -y install qemu-kvm if (($rhel_vers...

setup on central node 首先在central node生成CA 然后分别为nb、sb、switch创建private key和request 然后在centaral node(生成CA到机器)上对上一步生成的request进行签名，生成证书文件cert 然后把生成的pki/controllerca/cacert.pem and pki/switchca/cacert.pem 和private key和cert证书文件拷贝到其它computing node上 systemctl start ovn-northd systemctl start ovn-controller # 使用ovs-pki init --force生成controller CA和swit...

redhat doc shared storage setup 虚拟机迁移需要用到额外的共享存储。 迁移的过程中，源端把虚拟机内存和设备信息拷贝到共享存储上，目的端再从共享存储中获取。 可以搭建一个nfs服务器，让nfs服务器export /var/lib/libvirt/images,然后把迁移源端和目的端的/var/lib/libvirt/images目录都mount到nfs服务器。 这里面/var/lib/libvirt/images是创建虚拟机时指定的disk path，也可以使用其他路径。 因为机器有限，我这里把nfs服务放到源端。 # 启动nfs [root@hp-dl388g8-22 ~]# echo "/var/lib/libvirt/images *.redhat...
