<div dir="ltr">Thanks Fajar, I was unaware of the lxcfs. I will install it on my host. <div><br></div><div>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. </div><div><br></div><div>I am revisiting LXC again and this time the guest had to be a CentOS with following tasks in my mind : </div><div>- 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.</div><div>- Guest should be able to run openVSwitch, be able to create veth pairs, bridges and do all advanced networking.</div><div><br></div><div>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.</div><div><br></div><div>I am currently using Centos 7 host with lxc and lxc-template packages from EPEL</div><div><br></div><div>So in general, running priviledged CentOS guest on Ubuntu for above objectives should be OK and recommended right ? sorry its bit offtopic.<br><br>Going through your how to on Centos systemd on ubuntu.
