4.3. sVirt Configuration
SELinux Booleans are variables that can be toggled on or off, quickly enabling or disabling features or other special conditions. Booleans can be toggled by running either
setsebool boolean_name {on|off} for a temporary change, or setsebool -P boolean_name {on|off} to make the change persistent across reboots.
The following table shows the SELinux Boolean values that affect KVM when launched by libvirt. The current state of these booleans (on or off) can be found by running the command
getsebool -a|grep virt.
| SELinux Boolean | Description |
|---|---|
| staff_use_svirt | Enables staff users to create and transition to sVirt domains. |
| unprivuser_use_svirt | Enables unprivileged users to create and transition to sVirt domains. |
| virt_sandbox_use_audit | Enables sandbox containers to send audit messages. |
| virt_sandbox_use_netlink | Enables sandbox containers to use netlink system calls. |
| virt_sandbox_use_sys_admin | Enables sandbox containers to use sys_admin system calls, such as mount. |
| virt_transition_userdomain | Enables virtual processes to run as user domains. |
| virt_use_comm | Enables virt to use serial/parallel communication ports. |
| virt_use_execmem | Enables confined virtual guests to use executable memory and executable stack. |
| virt_use_fusefs | Enables virt to read FUSE mounted files. |
| virt_use_nfs | Enables virt to manage NFS mounted files. |
| virt_use_rawip | Enables virt to interact with rawip sockets. |
| virt_use_samba | Enables virt to manage CIFS mounted files. |
| virt_use_sanlock | Enables confined virtual guests to interact with the sanlock. |
| virt_use_usb | Enables virt to use USB devices. |
| virt_use_xserver | Enables virtual machine to interact with the X Window System. |
