Description Steffen Froemer 2021-07-21 13:59:18 UTC 
Description of problem:
With BZ#1944723 the supported maximum of virtual machine memory is increased to 16TB. Current Supported maximum [1] is 6TB.
In addition, the host maximum is at 12TB. Overall this does not make sense and should be clarified.

Moving out to 4.4.10 as 4.4.9 shipped live
Comment 2 Eli Marcus 2021-11-24 16:31:03 UTC 
Steffen, 
I discovered that Jiri Hermann had already updated the RHV limits article last August, but left it in Draft status. 
I spoke with Jiri, and he agreed that we can now publish those updates - 
please check if this meets your approval - https://access.redhat.com/articles/906543

and then we can mark this bug as "closed - current release"
Comment 3 Steffen Froemer 2021-11-25 16:04:56 UTC 
Hi Eli,
the VM limits are fine now. The host maximums are not. 

> Question: How to host a VM with 16TB on a host with 12TB to comply with support policy.

I would propose it to align with RHEL limits [1] as we have RHEL underneath.
So for RHEL7 based Hosts 12TB tested
and for RHEL8 based ones, 24TB tested.

Would that make sense?

Cheers, Steffen
