[root@localhost network-scripts]# brctl show

六,用virt-install生成.img文件
# virt-install --name=Ubuntu1 \
--ram 1024 --vcpus=1 \
--disk path=/root/ubuntu1.img,size=10 \
--accelerate --cdrom /root/ubuntu-14.04-desktop-amd64.iso \
--graphics vnc,port=5920 --network bridge=br0
如果报以下错误:
could not open disk image : Permission denied
解决方法:
[root@localhost ~]# cat /etc/libvirt/qemu.conf |awk '{if($0 !~ /^$/ && $0 !~ /^#/) {print $0}}'
vnc_listen = "0.0.0.0"
user = "root" //去掉注释
group = "root" //去掉注释
dynamic_ownership = 0 //去掉注释,把1改为0
dynamic_ownership = 0 //去掉注释,把1改为0
这一步做完,系统文件就好了。
七,启动虚拟机
如果报以下错误
[root@localhost ~]# virsh start ubuntu1
错误:域已经活跃
解决办法:
