Hi Oved!
That's a perfect explanation. Do we have a release date for 4.1? I'm
currently working with RHV in my production enviroment.
I may don't have the opportunity to wait for 4.1 to see the light as all my
customers VMs (im a web hoster) run on a non HA cluster as my provider does
not give me access to the IPMI. If anyone knows anyway to workaround this
limitation please do let me know.
Thanks a lot!
