DPDK-A3: KVM使用SRIOV和虚机使用DPDK

虚拟机基本管理

如下命令可以修改默认网段

sudo virsh net-edit --network default

<network>
  <name>default</name>
  <uuid>45ed012c-3933-4f3e-9575-b37bffa21b83</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:03:a7:5b'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

Enable forwarding

echo "net.ipv4.ip_forward=1" | sudo tee /etc/sysctl.conf

[root@netdev vm]# virsh list --all
 Id   Name     State
------------------------
 1    ubuntu   running

启动、关闭、删除

virsh [start/shutdown/destroy] vm

挂起和恢复

virsh [suspend|resume] vm

开机自启动

virsh autostart vm

查看信息

[root@netdev vm]# virsh dominfo ubuntu

克隆虚机

[root@netdev vm]# virt-clone -o ubuntu -n vm001 -f /home/vm/vm001.qcow2
Allocating 'vm001.qcow2'                                                                                                             | 100 GB  00:00:08
 
Clone 'vm001' created successfully.

克隆完成后， 需要uuidgen

[root@netdev vm]# uuidgen
10c35319-bd71-4447-aa1a-88207ec42fbf
[root@netdev vm]# vim /etc/libvirt/qemu/vm001.xml

删除虚机

virsh undefine vm

删除虚机并删除存储

virsh undefine vm --storage /home/vm/vm.qcow2
virsh undefine
