ECC (Error Correcting Code) mode is a feature of some NVIDIA GPUs that provides error detection and correction for memory errors. However, ECC mode can interfere with vGPU functionality and prevent vGPU-enabled VMs from being created or started1. Therefore, two correct steps to resolve this issue are B (Disable ECC by running nvdia-smi -e 0) and D (Check if ECC Mode is turned on by running nvdia-smi -q | grep “ECC Mode” -A2).

Microsegmentation is the specific functional capability within Nutanix Flow Network Security designed to control and restrict east-west traffic between virtual machines.

While traditional firewalls protect the perimeter (North-South), Microsegmentation applies stateful firewall policies directly to the vNIC of each VM. This allows an administrator to define granular rules that explicitly allow or deny traffic between individual VMs or groups of VMs (e.g., preventing a compromised VDI desktop from accessing a database server on the same subnet). This feature is the primary mechanism used to prevent lateral movement within the environment.

Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:

According to Nutanix AHV Administration Guide regarding GPU Pass-Through:

Hardware Binding: GPU Pass-Through (DirectPath I/O) binds a virtual machine to a specific physical PCIe device on the host. Unlike vGPU (which abstracts the hardware), passthrough creates a 1:1 dependency.

HA Behavior: Nutanix AHV supports High Availability (HA) for GPU-enabled VMs in the sense that if a host fails, the system attempts to restart the VM on another host (Cold Migration). Option C ("Not HA-capable") is incorrect because the system attempts the restart; it does not simply abandon the VM by design.

Failure Cause: The restart fails (the "behavior" described) because the destination host must have the exact same GPU hardware resource available (free and matching the profile/addressing). If the other nodes in the cluster do not have a free GPU of the same type, or if they are already fully utilized, the VM cannot power on, resulting in the "Insufficient GPU resources" error.

Citrix Workspace includes several components that can replace or integrate with the traditional Citrix infrastructure components, such as:

Citrix Cloud Services, which provide management and orchestration capabilities for Citrix Workspace, such as Citrix Virtual Apps and Desktops service, Citrix Gateway service, Citrix Endpoint Management service, etc.

Citrix Workspace app, which is a client software that enables users to access their apps and desktops from any device.

Citrix Cloud Connectors, which are software agents that establish a secure connection between Citrix Cloud Services and the on-premises or cloud-based resources, such as Active Directory, hypervisors, VDAs, etc.

According to Citrix documentation2, an administrator who chooses to move all of the backend Citrix infrastructure to be managed as a service by Citrix can use the following components:

Citrix Virtual Apps and Desktops service, which replaces the Citrix Delivery Controllers and provides centralized management and delivery of virtual apps and desktops.

Citrix Studio, which is still available as a web-based console for configuring and managing the virtual apps and desktops environment.

Citrix Gateway service, which replaces the Citrix NetScaler and provides secure remote access to virtual apps and desktops through a single URL.

Citrix StoreFront, which is still available as an optional component for providing users with self-service access to their apps and desktops through a web portal or native receiver.
