Subject Re: RE Update default template from CentOS 5.5 to CentOS 7
Date Wed, 11 Jul 2018 07:06:40 GMT
While the documentation may say it supports older hypervisors, we can remove hypervisors that
have reached end of life. I think if consider that, most support hypervisors (XS 6.5+, KVM
el6+/ubuntu14.04+ and VMware 55u3+) with latest patches applied would support CentOS7, perhaps
a hack could be used to register them as other linux 64-guest or as centos6.

We can attempt to officially say/deprecate the older hypervisors, for 4.12 we can aim to publish
a new centos7 as default guest template (along with a Ubuntu 18.04 template, so each new cloudstack
env has two of the most popular distros).

Subject: RE Update default template from CentOS 5.5 to CentOS 7

While it's good idea to bump up the current default VM template "CentOS 5.5(64-bit) no GUI
(KVM)" to a newer version. I doubt the candidate would be CentOS 7. Reason being the supportability
of the hypervisor. The candidate should be supported across all the versions of hypervisors
that next version of CloudStack would support. To support CentOS 7 we might have to drop support
for few of the versions listed below.

From 4.11 documentation the minimum versions supported are,
XenServer versions 6.1, 6.2 SP1, 6.5, 7.0, 7.1, 7.2 with latest hotfixes
VMware versions 5.0 Update 3, 5.1 Update 3, 5.5 Update 3b, 6.0 Update 2, and 6.5 GA

Subject: Update default template from CentOS 5.5 to CentOS 7


    I would like to propose updating our current default VM template "CentOS
    5.5(64-bit) no GUI (KVM)" to a newer version (e.g. CentOS 7). I also think
    that we could benefit from a wider set of templates offering also Debian,
    Ubuntu, and Fedora.
