Compatibility Matrix for CentOS and VMware
Hi
The compatibility matrix for Cloudstack 4.9+ lists specific minor OS versions for the management server with the exception of CentOS 7 which doesn't include a minor version. Is a fully patched CentOS 7 (7.4-1708) installation therefore supported? What happens with future minor OS releases, are these tested and supported as they are released?
The VMware 6.5 GA hypervisor is listed as supported in the compatibility matrix but in the installation guide it states "Be sure all the hotfixes provided by the hypervisor vendor are applied." Does this mean that VMware 6.5 U1 with latest patches is therefore supported too? What happens with future VMware hypervisor releases, are these tested and supported as they are released?
Compatibility matrix: http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/4.9.3.0/compat.html
Installation guide: http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/hypervisor/vsphere.html
Many thanks,
Julian Gilbert

Hi Paul
Thanks for your answer with regards to the hypervisor. It is very helpful to know that 4.9 may not have been completely reliable with vSphere 6.5.
As minor OS version updates are required in order to continue to receive security patches with CentOS 7 I will apply the same standard testing advice with regards to the management server OS.
If anyone knows of any incompatibilities with a fully patched CentOS 7.4-1708 management server or vSphere 6.5 U1 hypervisor I would be most grateful if you could reply.
Kind regards,
Julian Gilbert

Hi Julian,
I can answer the hypervisor question for you. The statement about keeping hypervisors patched is a bit of a catch-all to try to make sure that if there is an issue in someone's cloud, that CloudStack doesn't automatically get the blame (we find issues are more often hypervisor related rather than CloudStack related). But as you've highlighted, that's a double edge sword.
I'd saying that with vSphere, we use the VMware java libraries to do the orchestration of vSphere via vCenter, so the likelihood of any vSphere update within a version causing something to break is minimal. That said, I only know of community testing of 4.11 against 6.5GA at this time, the standard advice is - make sure that you test it thoroughly before trying anything new in production (and ideally let everyone in the community know the results).
As I recall 4.9 was not completely reliable with vSphere 6.5; the forthcoming 4.11 will be.
Kind regards,
Paul Angus
