23.07.2020 · For example, AHV-20170830.434 and AHV-20190916.231. The difference between them is that the versions starting with 2017 are built on CentOS 6 image, while the ones starting with 2019 are based on CentOS 7. It is very important to note that all the 2019 AHV versions are only compatible with AOS versions 5.16 and newer.

For example, if a CPU package has 10 cores, enabling hyperthreading presents 20 ... Microsoft Hyper-V and Nutanix AHV do not support this capability.

24.12.2021 · Interestingly enough, on AHV you’d also would need to check if the BIOS (see KB) to confirm if CPU settings were indeed set enabled. For VMWare see KB 80610 for a similar description/cpu info. EDIT: Wanted to mention a related Nutanix KB article which presents an interesting twist in situations where a power supply is out.

06.01.2021 · Nutanix AHV Networking (CLI commands) – VMwareGuruZ. AHV uses Open vSwitch (OVS) to connect the CVM, the hypervisor, and user VMs to each other and to the physical network on each node. The CVM manages the OVS inside the AHV host. Do not allow any external tool to modify the OVS. Open vSwitch (OVS) is an open source software switch designed ...

inter-VM concurrent attack vector on a AHV with hyperthreading enabled. Particularly if system load is typically below 50%. To 100% mitigate the concurrent attack vector Hyperthreading can be disabled at the hypervisor level via instruction in K B6137 . Note that Nutanix does not recommend you disable hyper-threading.
