篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了无法完成安装:'Cannot access storage file '/相关的知识,希望对你有一定的参考价值。

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.

  1.  
    # The user for QEMU processes run by the system instance. It can be
  2.  
    # specified as a user name or as a user id. The qemu driver will try to
  3.  
    # parse this value first as a name and then, if the name doesn‘t exist,
  4.  
    # as a user id.
  5.  
    #
  6.  
    # Since a sequence of digits is a valid user name, a leading plus sign
  7.  
    # can be used to ensure that a user id will not be interpreted as a user
  8.  
    # name.
  9.  
    #
  10.  
    # Some examples of valid values are:
  11.  
    #
  12.  
    # user = "qemu" # A user named "qemu"
  13.  
    # user = "+0" # Super user (uid=0)
  14.  
    # user = "100" # A user named "100" or a user with uid=100
  15.  
    #
  16.  
    user = "root"
  17.  
     
  18.  
    # The group for QEMU processes run by the system instance. It can be
  19.  
    # specified in a similar way to user.
  20.  
    group = "root"
  21.  
     
  22.  
    # Whether libvirt should dynamically change file ownership
  23.  
    # to match the configured user/group above. Defaults to 1.
  24.  
    # Set to 0 to disable file ownership changes.
  25.  
    #dynamic_ownership = 1

cat /etc/passwd

qemu:x:107:107:qemu user:/:/sbin/nologin

 

ll /root/x.qcow2

-rwxrwxrwx 1 qemu qemu 1957691392 Dec  1 14:16 /root/x.qcow2

 

在各种权限都对的情况下,依然不能create

 

sed -i ‘s/#vnc_listen = "0.0.0.0"/vnc_listen = "0.0.0.0"/g‘ /etc/libvirt/qemu.conf

sed -i ‘s/#group = "root"/group = "root"/g‘ /etc/libvirt/qemu.conf

sed -i ‘s/#user = "root"/user = "root"/g‘ /etc/libvirt/qemu.conf

 

 

service libvirtd restart

 

 

UUID=0654F28654F277AF  /media/h1/newsntfs          ntfs    defaults,nls=utf8,umask=111,uid=0,gid=0,dmask=000,fmask=000        0      0
