本文介绍了在使用virsh创建虚拟机过程中遇到的存储文件权限被拒绝的问题及解决方案。通过修改/etc/libvirt/qemu.conf配置文件中的用户和组设置为root，并启用动态所有权变更功能，成功解决了virsh操作虚拟机时的权限问题。

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
