Hi, We installed Openstack (liberty) in centos7. Issue is While we are launching ubuntu instances from flavours (customized flavour and with default flavours) with empheral disk less than 7 GB, throwing error space unable to install the ubuntu, and if we give more than 7GB as empheral disk, ubuntu gets installed successfully. And what ever space we mentioned in root disk is not showing after launching the instance. Please help us on the above issue.
