Fixed In Version: libguestfs-1.32.0-2.el7
Doc Type: Release Note
Doc Text:
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.

Comment 3 Richard W.M. Jones 2015-09-23 14:29:21 UTC
We're going to rebase to libguestfs 1.32 (bug 1218766), and
that version includes this fix.

Comment 6 Xianghua Chen 2016-08-03 10:03:36 UTC
Verified with packages:

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.
