Public bug reported:

python-nova-2015.1.1-1.el7.noarch
openstack-nova-common-2015.1.1-1.el7.noarch
python-novaclient-2.23.0-1.el7.noarch
openstack-nova-compute-2015.1.1-1.el7.noarch
python-oslo-vmware-0.11.1-1.el7.noarch

I can't snap an instance if the root disk is too large. (>8GB)

Snap in Vcenter works, OVF export works, DL image on glance node works,
but after the DL, compute have trace and delete glance image.

Trace in compute.log ==>

  I can't snap an instance if the root disk is too large. (>8GB)

  Snap in Vcenter works, OVF export works, DL image on glance node
  works, but after the DL, compute have trace and delete glance image.
