Accessing guest disks on *virt-manager* works properly with SELinux and _libguestfs-python_
Prior to this update, when the _libguestfs-python_ package was installed and SELinux was enabled on the host machine, accessing guest disks using the *virt-manager* interface caused I/O failures. Now, *virt-manager* and the _libguestfs_ library share the same _libvirt_ connection, which prevents the described failures from occurring.

Verified with packages:
libguestfs-1.33.46-1.el7.x86_64
Verify steps:
1. Prepare a RHEL guest image and start it:
# virsh start rhel6.8
# virsh list --all
Id Name State
----------------------------------------------------
2 rhel6.8 running
2. Login into the guest:
# virsh console 2
Try to write to the disk:
# while sleep 1; do echo a > ~/output; done
3. On host, run following command:
# guestfish --ro -i rhel6.8.qcow2
Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.
Type: 'help' for help on commands
'man' to read the manual
'quit' to quit the shell
Operating system: Red Hat Enterprise Linux Server release 6.8 (Santiago)
/dev/vg_dhcp8136/lv_root mounted on /
/dev/sda1 mounted on /boot
><fs> ls /
....
4. Check the command running status in guest in step 2, there is no error like:
# while sleep 1; do echo a > ~/output; done
kernel:journal commit I/O error
bash: /root/output: Read-only file system
...
So verified.
