[Cialug] VM redeux, .. Docker

[Theron Conrey]

Beyond the centos docs there are quite a few good tutorials out there. Virt-manager has been out for years and some of the blog posts out there need to be time filtered as well as quality filtered. Just did a quick search from my phone and this one looks reasonable, possibly a bit dated: http://jensd.be/207/linux/install-and-use-centos-7-as-kvm-virtualization-host

Flushing out earlier comments and granted this is all back of napkin configurations, here's an approach I'd support if I was looking at an environment today:

Base layer: minimal centos install/ kvm / virsh / selinux (the same base hypervisor security applies to all mgmt layers) 

Small environment mgmt: (1-5 hosts no shared storage) = virt-manager

Medium environment mgmt: (2-50ish hosts with shared storage) = oVirt 

Large-ish environment mgmt: (50-100s hosts with mixed storage requirements) = opennebula.org or openstack (rdo to stay with RH family theme)

I'd be willing to do a virt-manager power install during a LUG meeting in the next couple months if anyone is interested.  While I'm more familiar now with RH-land I'm a converted debuntu guy where I used to use Xen and could prob do a decent job assisting if needed with migrating VMs.

Things get interesting if you want to move beyond a single host and want to do open source shared storage, or anything more complex than simple bridged networking (ala open vSwitch) for guest networks but it's completely doable.
