Migration from oVirt 4.3 to OLVM 4.4
I would like to transition a single node with hosted engine from oVirt 4.3.9 to OLVM 4.4.10
Virtual machines are stored on local storage domain, only the HE is stored on Gluster storage domain (automatically done at installation time).
I would like to avoid downtime. I have a spare machine available.
Can I install OLVM on that spare machine and somehow make it talk to oVirt to migrate it's VM's, then wipe the original oVirt machine, install OLVM on it and add it into the new OLVM domain, and then transfer back all vm's into the original physical machine as well as the HE, then finally decomission the temporary node?
