[ovirt-users] gluster VM disk permissions

[Bill James]

I just tried importing using the import script and got this error:

[root at ovirt1 prod ~]# import-to-ovirt.pl 
/mnt/tmp/puppetdb.j2noc.com.disk.xm 
/rhev/data-center/mnt/j2hqnap02:_vol_ovirt__inside__export_exportTemplates
libvirt needs authentication to connect to libvirt URI qemu:///system
(see also: http://libvirt.org/auth.html http://libvirt.org/uri.html)
Please enter your authentication name: vdsm at ovirt
Please enter your password:
could not create appliance through libvirt.

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct

Original error from libvirt: internal error: process exited while 
connecting to monitor: 2016-05-24T18:10:21.651694Z qemu-kvm: -drive 
file=/tmp/libguestfsWx9FbI/overlay1,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=unsafe: 
Could not open '/tmp/libguestfsWx9FbI/overlay1': Permission denied
  [code=1 domain=10] at /usr/local/bin/import-to-ovirt.pl line 233.


I believe this is the same error that prompted me to use "user = root" 
in qemu.conf, but sounds like there is a better resolution?
