The selinux virtual machine image context configuration file
The virtual_image_context file contains a list of image contexts for use by the SELinux-aware virtulization API libvirt (see libvirtd(8)).
selinux_virtual_image_context_path(3) will return the active policy path to this file. The default virtual image context file is:
/etc/selinux/{SELINUXTYPE}/contexts/virtual_image_context
Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).
Each line in the file consists of an entry as follows:
user:role:type[:range]
Where:
user role type range
A user, role, type and optional range (for MCS/MLS) separated by colons (:) that can be used as a virtual image context.
