The Nutanix administrator should deploy NGT on the VM and then enable this feature. For more information on enabling and mounting NGT, see the Enabling and Mounting Nutanix Guest Tools. After the feature is enabled and a disk is attached, the guest VM administrator can recover files within the guest operating system. If the guest…
Cloud-init Cloud-init is a utility that is used to customize Linux VMs during first-boot initialization. The utility must be pre-installed in the operating system image used to create VMs. Cloud-init runs early in the boot process and configures the operating system on the basis of data that you provide (user data). You can use Cloud-init…
The Nutanix cluster automatically selects the optimal path between a hypervisor host and its guest VM data. The Controller VM has multiple redundant paths available, which makes the cluster more resilient to failures. When available, the optimal path is through the local Controller VM to local storage devices. In some situations, the data is not…
VM High Availability Modes Default: This does not require any configuration and is included by default when an Acropolis Hypervisor-based Nutanix cluster is installed. When an AHV host becomes unavailable, the failed VMs that were running on the failed AHV host restart on the remaining hosts, depending on the available resources. Not all of the…
Live migration lets you move a user VM from one Acropolis host to another while the VM is powered on. This feature follows similar resource rules as VMHA to determine if migration can occur—as long as enough RAM and CPU cycles are available on the target host, live migration will initiate. Live migration can be…
Backplane traffic is intra-cluster traffic that is necessary for the cluster to function, and comprises traffic between CVMs, traffic between CVMs and hosts, storage traffic, and so on. (For nodes that have RDMA-enabled NICs, the CVMs use a separate RDMA LAN for Stargate-to-Stargate communications.)
Active-backup The Active-Backup bond mode is the simplest, easily allowing connections to multiple upstream switches without any additional switch configuration. The downside is that traffic from all VMs use only the single active link within the bond. All backup links remain unused. In a system with dual 10 gigabit Ethernet adapters, the maximum throughput of…
