[one-users] ONE 3.2 VM Management issues

Hello.

Thanks for the response.   I followed the published instructions for KVM when I installed ONE.   dymanic_ownership = 0 is definitely in /etc/libvirt/qemu.conf on both of my compute nodes.   I'm still getting the CHOWN (0,0) error.   I have a work around in place at the moment, where by my NFS storage is exported with no_root_squash (not desired, and should not be necessary given that QEMU is running as oneadmin).

As a concequence (I think) of the above, I'm unable to successfully shutdown a VM.   Once it starts, selecting it and clicking Shutdown simply returns the machine back to running state on the next poll interval.   I've also disabled apparmor for libvirt by touching /etc/apparmor.d/disable/usr.sbin.libvirtd.   


The information about contextualization did the trick.   That seems to be working fine.

Thank you.
