今天自己編譯了spice-protocol spice-gtk spice qemu,然後想用virsh去創建一個虛機：
# virsh define demo.xml 定義域 demo（從 demo.xml） # virsh start demo cannot access storage file (as uid:107, gid:107) permission denied 解決方法：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
cat /etc/passwd
