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
