KVM增加磁盘
1、创建文件磁盘镜像qemu-img create -f raw /data/virtualdisk/server-5911-1t.img 1020G2、通过virsh 管理工具加载磁盘virsh # edit test-5911-server <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/data/virtualdisk/test-5911-server.img'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/></disk>下面是新增加 <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/data/virtualdisk/server-5911-1t.img'/> <target dev='vdb' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/></disk>4、重启虚拟机注意要先destroy再start不然配置不会生效virsh # destroy test-5911-servervirsh # start test-5911-server5、其他就是进入系统，分区，挂载
