Centos8 template cleanup suggestions please

vimalware — Wed, 11 Dec 2019 05:28:14 +0000

Background : I haven't really used any Redhat distro regularly since 2006 .
At this point, I am a sort of a noob to all the changes in centos land (learning a ton over the weekend.)
At least systemd is the same everywhere.

So, I decided to make a centos8 KVM base template for my proxmox nodes after realizing that apnscp is CENTOS-only. (I usually just use hetzner cloud for Centos)

Here is a gist I found online (minus some vmware guest agent) Credit : https://gist.github.com/efeldhusen/4bea2031525203b1658b444f4709c12c
Any Edits or other suggestions members have for Centos8 compatibiliy?
It mostly looks good to me.

OpenVZ 7 / Virtuozzo 7 Minimal templates

I made a complete set a few days ago, thought I would share them as I don't see them anywhere else.
These are fully functional and VERY minimal templates for OpenVZ 7/ Virtuozzo 7, all tested.
They range from 5mb to 9mb ram used on initial deployment:
http://185.164.137.206/vz7/
For SolusVM you will need to be on at least the latest mainline release (probably better off on beta - upcp 3) which enables the EZ templates option when adding an OpenVZ templates in solusvm
I have spend a fair bit of time working with the EZ template system now, its very different to OpenVZ 6 or "legacy templates" as they are now known so if anyone needs any help just shout up, not enough info public at this stage.

If your host does not have them available yet point them here
