Virtual XOS killing ESX host CPU

[Konstantin_Mikh]

After initial install and configuration of the vSummit, VM stays at around 60-100Mhz host CPU usage but after about 3min sitting idle, CPU utilization jumps to 3GHz+ and in many cases maxes out Host CPU resources.

Extreme VM performance becomes sluggish and in many cases CLI freezes.

Tested on multiple hosts in the Datacenter with the same outcome.

No other VMs on the hosts (Linux, Windows, Juniper, Fortinet, Cisco, Checkpoint, Avaya) produce the same issue.

Anyone experienced this behavior and if yes, is there a fix/workaround for it?

Specs:

Extreme vXOS ver 16.1.2.14 - same issue with earlier releases.
VMWare vSphere 5.5 with latest patches.
CPU: Xeon 3.2GHz E3-v1225 - 4 Cores

Thank you.
