Just run yum install https://www.virtkick.io/download/latest.rpm on a clean CentOS or openSUSE and VirtKick is ready to play on http://yourserver:3000/. No need to deal with any config files. :-) Things can be that easy, can't they?
If you don't have CentOS by hand, you can install VirtKick on DigitalOcean. They offer nested virtualization, so all will work good.
As always, I'm open for your feedback. If you encounter any problems, please report an issue on GitHub.
By the way: it's the last 30 hours of our crowdfunding. We already raised ~22k from multiple sources, and we're only ~$5k away from reaching the third goal: support for OpenVZ.
In case someone doesn't yet know VirtKick, it's an open source VPS panel, similar to DigitalOcean. More at https://www.virtkick.io/.
