Hi all,
I have a banking customer asking if CentOS is compatible on RHV4.0 as a guest VM. Based on Red Hat’s knowledge base (see link below), CentOS not supported guest OS.
However, VMware say on their official document, CentOS is a compatible guest OS (see link below). So, in my customer's mind, CentOS cannot be used as a guest OS in RHV cause it is not compatible, which I find it hard to believe considering the relationship between CentOs and RHEL.
RHV supported guest OS https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/htm...
VMware compatible guest OS https://partnerweb.vmware.com/comp_guide2/pdf/VMware_GOS_Compatibility_Guide...
So, my question is, technically, can CentOS run as a guest OS on RHV4? Is there anyone that has done extensive test with CentOS on RHV? Is there any documentation or links that can show CentOS will run fine on RHV4? Just need to show customer that indeed CentOS is technically compatible on RHV but just not supported by Red Hat.
Many thanks.
p/s: If you’re wondering why I’m not getting the customer to migrate CentOS to RHEL just so that it’s a supported configuration? well, for some reason he just wants to continue using CentOS, which I’m guessing could be caused by $$$ as they have heaps of CentOS in their environment.

You answered yourself basically, yes CentOS is essentially RHEL and it will run. Now, the article refers to "support" and that is different topic. It means that when you call Red Hat Support they will be able to help you with hypervisor if the guest does not operate properly. People often confuse phrase "is supported" with "does it run".
Just make sure to select RHEL 7 guest configuration for CentOS 7 so proper drivers are in use for optimal performance.

CentOS is tested extensively in oVirt, the RHV upstream opes-source project. In fact, most of the project's build and test infrastructure is based on CentOS VMs running on oVirt.
Having said that, if your customer bought RHV support licenses, running CentOS on it may or may not violate his support licensing terms. Please verify that with an official RedHat sales representative or a TAM.
Please note that this response is based on my personal knowledge only and should not considered an an official response from Red Hat in any way.

I'm no expert on this, but I think I recall that licensing RHEL instances on RHV is way cheaper then licensing them on VMware or any other virtualization infrastructure, maybe you should look into this. </sales pitch ;>
If he still prefers to stay on CentOS, perhaps he can be convinced to use oVirt so he can still jump-ship from VMware.
