Re: [ovirt-users] Hyper converged network setup

1. Yes, you can do this 2. Yes, In linux it's called bonding and this can be done from the UI 3. You can get around using the Engine machine if required with virsh or virt-manager - however I would just wait for the manager to migrate and start on another host in the cluster 4. The deployment will take care of everything for you. You just need an IP 5. Yes, you can use vlans or virtual networking(NSXish) called OVS in oVirt. I noticed on your deployment machines 2 and 3 have the same IP. Might want to fix that before deploying Happy trails ~D On Tue, Sep 12, 2017 at 2:00 PM, Tailor, Bharat < bharat(a)synergysystemsindia.com&gt; wrote: > Hi Charles, > > Thank you so much to share a cool stuff with us. > > My doubts are still not cleared. > > > 1.
