无法完成安装:'Cannot access storage file '/

今天自己编译了spice-protocol spice-gtk spice qemu,然后想用virsh去创建一个虚机：

# virsh define demo.xml

    定义域 demo（从 demo.xml）

# virsh start demo

    cannot access storage file (as uid:107, gid:107)  permission denied

解决方法：

     

Changing /etc/libvirt/qemu.conf make working things.
Uncomment user/group to work as root.

# The user for QEMU processes run by the system instance. It can be
# specified as a user name or as a user id. The qemu driver will try to
# parse this value first as a name and then, if the name doesn't exist,
# as a user id.
#
# Since a sequence of digits is a valid user name, a leading plus sign
# can be used to ensure that a user id will not be interpreted as a user
# name.
#
# Some examples of valid values are:
#
# user = "qemu" # A user named "qemu"
# user = "+0" # Super user (uid=0)
# user = "100" # A user named "100" or a user with uid=100
#
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 = 1

在各种权限都对的情况下，依然不能create
