使用virt-install安装vm的时候出现了一下错误，解决方法如下：
$sudo ./create-vm-demo.sh
Starting install…
ERROR internal error process exited while connecting to monitor: char device redirected to /dev/pts/2
kvm: -drive file=/home/muge0913/workstation/kvm/test.img,if=none,id=drive-ide0-0-0,format=raw: could not open disk image
/home/muge0913/workstation/kvm/test.img: Permission denied
解决:编辑/etc/libvirt/qemu.conf添加内容如下，这样root就有操作的权限了。
user = “root”
# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
group = “root”
# Whether libvirt should dynamically change file ownership
# to match the configured user/group above. Defaults to 1.
# Set to 0 to disable file ownership changes.
dynamic_ownership = 0
#vrish list查看虚拟机运行情况
