[ovirt-users] To oVirt or not to oVirt

Good day all! have been a KVM user/admin for the last few years and have configured all aspects using either VirtManager or CLI where required. am about to reinstall my development system and started to look at using CentOS7 as the host, and to get a more recent version of KVM. After a little search around I came across oVirt and am considering whether to install this now and use it as the main configuration tool. do have a couple of questions which hopefully somebody will be able to help with? at present I am using OpenVSwitch with KVM so that I could use the vlan capabilities and wish to ask whether will need to move away from that to a different solution ? On my host I already have about 10 VMs that I wish to keep and whether I could migrate them into oVirt ? I have been using LVM volumes as raw storage for the VM images so presume would need to convert them to a different format for use ? one of my VMs actually acts as a storage provider, using Quantastor, which then presents storage to other VMs using iSCSI which hope I can still use in oVirt ? Apologies if these questions are a little vague but am trying to get my head around how it would all work. Thank you, Phil
