A VMs Rubrik-assigned UUID will change when either the vCenter Server or its moRef. Therefore, the UUID and InstanceUUID fields will be the same value. vSphere supports both existing and next-gen workloads through simple. Hyper-V does not have a concept of UUID vs InstanceUUID. If the value is already present in the config file (and there is no duplicate in the current inventory), it’s left intact. It’s unique and is generated when you add a vm to inventory (or create a vm). vmx file), which is generated by vCenter and is unique within a single vCenter (two VMs in different vCenters can have the same Instance UUID).When VMs are failed over, Instance UUIDs are changed. vc.uuid is used by vCenter to identify vm together with MoRef ID you’ve seen while working with PowerCLI. This introduced Instance UUID (vc.uuid in. What is Version 4 UUID A Version 4 UUID is a universally unique identifier that is generated using random numbers.

If a VM is cloned, the clone will have the same BIOS UUID. vmx file) was the original VM identifier implemented to identify a VM and is derived from the hardware VM. This new UUID is based on the physical computer's identifier and the path to the virtual machine's configuration file in its new location. If a virtual machine is moved or copied, the Workstation offers the choice of creating a new UUID the first time a virtual machine is powered on. A UUID (Universally Unique Identifier) can be used for multiple purposes, from tagging objects with an extremely short lifetime, to reliably identifying very persistent objects across a network, particularly (but not necessarily) as part of an ASN.1 object identifier (OID) value, or in a Uniform Resource Name ().UUIDs are an octet string of 16 octets (128 bits).

To ensure all virtual machines are identified properly, each virtual machine is automatically assigned a universal unique identifier (UUID). Instance UUID column (blank for Hyper-V VMs) For example, you have 2 virtual machines VM1 and VM2 with the same UUID (which is called Instance UUID for VMware, and VM UUID for Hyper-V) in the ESXi hosts. a) Generate new UUId using uuidgen utility : uuidgen fb5c697b-d1d6-49ab-afcd-27a22a5007c8 b) Please take note that the UUID may only be changed when the filesystem is unmounted.

VMware UUID and Instance UUID values already exist in the following excel: Visit VMware Technology Network Design Standards Architecture and design standards and guidelines to help you deliver integrated solutions and ensure optimal user experiences. Optical Prime will add UUID and instance UUID columns to the VM tab in the general excel. Optical Prime currently displays the VM UUID and Instance UUID for VMware VMs only in the VMware excel. Live Optics Optical Prime will be adding UUID information for Hyper-V VMs to the General Optical Prime Excel spread sheet.
