https://bugzilla.redhat.com/show_bug.cgi?id=1413922 While all the code that deals with qemu namespaces correctly detects whether we are running as root (and turn into NO-OP for qemu:///session) the actual unshare() call is not guarded with such check. Therefore any attempt to start a domain under qemu:///session shall fail as unshare() is reserved for root. The fix consists of moving unshare() call (for which we have a wrapper called virProcessSetupPrivateMountNS) into qemuDomainBuildNamespace() where the proper check is performed.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
