If you really know what you are doing and are confident can get yourself
out of a problem, then you can force Cloudstack to register your Ubuntu
new server as CentOS by editing this script on the hv (prior to host
addition):
/usr/share/cloudstack-common/scripts/vm/hypervisor/versions.sh
Once you have migrated all your CentOS servers, you can edit the
"host_details" DB table and replace CentOS with Ubuntu.

Hi,
Cloudstack tries to keep that demarcation between OSes so as to
maintain some sort of compatibility where software versions and
capabilities are concerned, for stability's sake.
That said, it can be bypassed in code, but it's best to do it like you
have already shown by using another pod.

log file
"Can't add host: XX.XX.XX.XX with hostOS: Ubuntu into a cluster,in

Is this really the case? I did not see anything obvious in the
documentation about this. I was able to successfully add the new
Ubuntu
server into a new cluster within the same POD, and have it see
storage,
networking, etc, so the host itself appears to be configured
correctly.
