Description of problem: For SAP HANA certification of VMs with 12TB of memory, it's required to have VMs in RHV supporting this amount of memory Version-Release number of selected component (if applicable): RHV-4.4.z How reproducible: Steps to Reproduce: 1. Create a VM in RHV UI 2. Change amount of Memory to 12 TB 3. Actual results: Currently, it's not supported by Red Hat to run VMs with Memory > 6TB Expected results: A VM should be possible to create and started Additional info: https://access.redhat.com/articles/906543
Verified with: ovirt-engine-4.4.6.5-447.gd80dda7.9.el8ev.noarch Steps: QE doesn't have HW supporting 16TB memory VM, so only check if setting maximum memory to 16TB works. 1. Create a VM on UI, set maximum memory to 16TB, run it. 2. Create a VM via API, set maximum memory to 16TB, run it: <vm> <name>testvm16T_api</name> <memory>1073741824</memory> <memory_policy> <guaranteed>1073741824</guaranteed> <max>17592186044416</max> </memory_policy> <template> <name>latest-rhel-guest-image-8.3-infra</name> </template> <cluster> <name>golden_env_mixed_1</name> </cluster> </vm> Results: 1. VM with 16TB maximum memory can be created and started successfully on UI. 2. VM with 16TB maximum memory can be created and started successfully via API.
