Public bug reported:

ICEHOUSE install, CentOS 6.5 using RDO repositories but installation
does not use Packstack.

If you launch an image with a Disk size that is too small for what is
needed and --min-disk is not  set the compute log reports correcly
FlavorDiskTooSmall: Flavor's disk is too small for requested image .
But this error also causes an error similar to the one below after the
FlavorDiskTooSmall.

This means that nova show for the instance that failed shows the reason
for the failure as the ovs-vsctl command failing rather than
FlavorDiskTooSmall.

Title:
  Incorrect Error Message displayed when FlavorDiskTooSmall

Status in OpenStack Compute (Nova):
  New

Bug description:
  ICEHOUSE install, CentOS 6.5 using RDO repositories but installation
  does not use Packstack.

  If you launch an image with a Disk size that is too small for what is
  needed and --min-disk is not  set the compute log reports correcly
  FlavorDiskTooSmall: Flavor's disk is too small for requested image .
  But this error also causes an error similar to the one below after the
  FlavorDiskTooSmall.

  This means that nova show for the instance that failed shows the
  reason for the failure as the ovs-vsctl command failing rather than
  FlavorDiskTooSmall.
