centos6.6挂载ntfs分区后，在ntfs分区上建立虚拟机：
virt-install --name=centos6.5 --ram=1024 --vcpus=2 -f centos6.5.raw -s 20 -l /media/data/iso/CentOS-6.6-x86_64-bin-DVD1.iso
时报错：
ERROR internal error process exited while connecting to monitor: char device redirected to /dev/pts/1
2015-06-01T10:46:15.600835Z qemu-kvm: -drive file=/media/data/centos6.5.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none: could not open disk image /media/data/centos6.5.raw: Permission denied
提示ntfs分区拒绝访问，检查权限正常。
关闭selinux后发现虚拟机启动正常
setenforce 0
kvm install 报错could not open disk imageXXX: Permission denied
