[Qemu-devel] unable to set security context error ...

[Onkar N Mahajan <kernzap@gmail.com>]

I am getting  'system_u:object_r:svirt_image_t:s0:c129,c783' on 
'/var/lib/libvirt/images/vm01.img': Permission denied'
when I try to install using virt-manager.

#semanage fcontext -l | grep images
/var/lib/libvirt/images(/.*)?                      all files          
system_u:object_r:svirt_image_t:s0

and

#ls -aZ
drwxr-xr-x. root root unconfined_u:object_r:virt_var_lib_t:s0 .
drwxr-xr-x. root root system_u:object_r:virt_var_lib_t:s0 ..
-rw-------. root root system_u:object_r:svirt_image_t:s0 vm01.img


Installation fails with following error message :
