AOS New Features

Nested VM.
  • Nutanix now provides limited support for nested virtualization, specifically nested AHV VMs in an AHV cluster as of AOS with AHV-20170830.58. Enabling nested virtualization will disable live migration and high availability features for the nested VM. You must power off nested VMs during maintenance events that require live migration.

AOS Updated Features

Consistency Group Update
The maximum number of entities (VMs, volume groups) supported in a consistency group is increased to 20 as of AOS 5.5. A consistency group is a subset of the entities in a protection domain. A consistency group typically should not exceed more than 20 entities.

What’s New for Checks in NCC

Updated Checks
  • For check_license_compliance, new alert IDs A1085 and 14004 have been added for license capacity (the cluster is licensed adequately for use) and is related to the Nutanix Coins feature. Cluster capacity is calculated from physical cores and HDD/SSD storage amount in the cluster.
  • a_status_check has been updated to correctly check for valid configurations containing NVMe and SSD drives.
  • The BIOS checking function of bmc_bios_version_check is temporarily disabled in this release for Nutanix G6 platforms (X11 motherboards).
  • dimm_interop_check has been further updated to check for unsupported DIMM configurations for NX Series G6 platforms.

Resolved Issues

  • After upgrading a Prism Central-managed cluster to AOS 5.5, an Alert Manager alert was seen in the Prism Central web console (Critical : Alert Manager data from cluster XX is not up-to-date).
