1. 启动

virsh start [name]

2. 停止

virsh stop[name]

3. 重启

virsh restart [name]

4. 查看所有的列表

virsh list --all

批量按照windows项目总结

安装kvm相关包：
apt install qemu-kvm virt-manager libvirt-daemon-system
sudo systemctl --now enable libvirtd
mkdir /filecoin_1/kvm/libvirt -pv
sudo mv /var/lib/libvirt /filecoin 
sudo ln -sv /filecoin_1/kvm/libvirt /var/lib/libvirt

通过xml文件创建虚拟机：
virsh define /etc/libvirt/qemu/win-test.xml


os-images:/filecoin_1/kvm/libvirt/person/os-images/
file:/filecoin_1/kvm/libvirt/images/win/

win10: /filecoin_1/kvm/libvirt/person/os-images/Windows10.iso
host=win1 && qemu-img create -f qcow2 $host/$host.qcow2 40G

克隆虚拟机
host=win2 && virt-clone -o  windows10-test -n $host -f /filecoin_1/kvm/libvirt/images/win/$host/$host.qcow2

/filecoin_1/kvm/libvirt/images/win/win1/win10-1.qcow2

内存管理：
https://www.cnblogs.com/ygbh/p/17420868.html

virt-install --virt-type kvm --name windows10 --ram 4096 --vcpus 2 \
--cdrom=/filecoin_1/kvm/libvirt/person/os-images/Windows10.iso \
--disk path=/filecoin_1/kvm/libvirt/images/win/win-test/win-test.qcow2 --network network=default \
--graphics vnc,listen=0.0.0.0 --noautoconsole


for i in `seq 24 50`;do host=win$i && virt-clone -o  windows10-test -n $host -f /filecoin_1/kvm/libvirt/images/win/$host/$host.qcow2;done

kvm配置网桥网络（虚拟机和物理机在同一个内网）

网桥配置完成后，需要检查两个内核参数配置

1. ipv4转发配置
2. bridge-nf-call-iptables 网桥iptables设置问题
   cat /proc/sys/net/bridge/bridge-nf-call-iptables

值 要为0，不为0 需要重置

echo 0 > /proc/sys/net/bridge/bridge-nf-call-iptables

sudo tee /etc/sysctl.d/kubernetes.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF
