Hi All,
I've just joined the mailing list as my organisation needs a new virtualisation solution. VMware is prohibitively expensive for a small company like ours and of all the opensource solutions, oVirt looks like the best fit for our needs.
Our existing virtual infrastructure is primarily made up of an old vSphere 5 cluster (expired license on old and out of warranty hardware) and a couple of newer standalone (free) ESXi servers. Both the cluster and the standalones have shared NFS storage so I can move VMs around.
I want to take a couple of older (2014ish) servers which will serve as the management host and one compute node initially. Then, I'd like to migrate VMs from one vSphere host at a time to the newly created oVirt cluster and convert the now empty vSphere ESXi hosts into oVirt compute nodes as I go.
Firstly - Would new compute host hardware (2020) work in a (2014) based ovirt cluster?
Generally speaking, yes.
If so
Would I be able to take advantage of the more advanced features of ovirt like live migration etc.. with a mix of new and old hardware
Generally speaking - yes, if you set the cluster cpu level to be the lowest common denominator of your existing machines. Simplest way to do this, I think (didn't verify), is to add to your new empty cluster first the oldest host, as I think the cluster conf is set based on the first host. Best regards, -- Didi
