LXC over KVM in VE 4.1

[btel]

Hi All:

I just installed and playing around with latest CE 4.1. I had impression that since it uses LXC containers so all guest must have same OS. But I'm still able to install CentOS 6 and CentOS 7 separate guest images. Can someone explain the basic here & point right documents?

Thanks a lot.

In PVE 4 you have the choice among two guest technologies - QEMU/KVM for full virtualization, this supports a range of guest operating systems (not only Linux, but also BSD, Windows, ..) and LXC for containers, which as the name Linux Containers implies, only supports Linux guests (because the kernel is shared with the host operating system). LXC guests can run a different Linux distribution than installed on the host (for example, a Proxmox VE host can run Debian, Ubuntu, Redhat, Suse, .. guests).
