Thanks Fajar, I was unaware of the lxcfs. I will install it on my host. I would love to move back to Ubuntu since I had used it with LXC about a year back and I was happy with it, although that time it was just a basic app and a db that I was using it for and it didn't complain about anything.
I am revisiting LXC again and this time the guest had to be a CentOS with following tasks in my mind : - Guest should be able to run a full KVM inside it, I don't intend to run it heavy but need it for some compute experiments. - Guest should be able to run openVSwitch, be able to create veth pairs, bridges and do all advanced networking. So I started with priviledged Centos 7 containers on Ubu 14.04, I faced some issues and moved to having CentOS 7 host, probably I should revisit using Ubuntu. I am currently using Centos 7 host with lxc and lxc-template packages from EPEL So in general, running priviledged CentOS guest on Ubuntu for above objectives should be OK and recommended right ? sorry its bit offtopic. Going through your how to on Centos systemd on ubuntu. Thanks for that - Rahul On Tue, Feb 9, 2016 at 4:10 PM, Fajar A.
