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,
