This identifier is used for VMFS Heartbeat and Journal operations so if multiple hosts have the same UUID, this case lead to a split-brain situation as the ESXi hosts will attempt to access each otherâs metadata regions on VMFS. When an ESXi boot device is cloned, the System Universal Unique Identifier (UUID) is also cloned. Any datastores that become corrupt as a result of duplicate System UUIDs will need to be reformatted after evacuating the present VMs. Example 12-9 shows the typical content of that file in a working Ubuntu. Power OFF the vApp in Cloud director UI 2. The only supported solution at this time is to rebuild the ESXi hosts, which will generate a new System UUID. of a new MAC address/UUID without displaying the VMware dialog box. Workaround 1: Manually removing the bios UUID from vmx file 1. ![]() There are additional dependencies on unique System UUIDs in ESXi 7.0 (Encrypted keys for TPM, etc) as we always expect the System UUID to be unique and not copied. Use operating system tools to get the UUID of a VM. uuid. Search the file for the line: uuid.bios Enter the new UUID in this format.Edit the virtual machineâs configuration file (. However if ESXi boot devices is clonede also the System UUID is replicated, which can lead to VMFS corruption if multiple hosts with the same System UUID share the same VMFS volumes, as there are dependencies in the storage stack that uses the System UUID for operations like VMFS journaling and VMFS Heartbeat operations. Power off the virtual machine whose UUID you are going to change. VMware Fusion Pro Trial 30 days Fusion Pro Experience the easiest way to run Windows on a Mac and the ultimate tool for building apps to run on any platform. to the VMware tools, virtual machine ID, VM SMBIOS UUID, VM UUID. This may happen as ESXiâs operating system expects that each server will have a unique System Universally Unique Identifier (UUID). VMware Fusion Free Product Fusion Player Download and use the free personal use license available with a valid MyVMware account. NET (4.6.2 or higher) application which uses VMware vSphere Management SDK 8.0 and CIS. NOTE: After upgrading to ESXi 7.0U2, corruption can occur on VMFS datastores if the ESXi hosts sharing those LUNs had their boot devices cloned (84349) Another option for uuid.action is 'change'. Please remember that this workflow is not at all supported by VMware. If the valid uuid.bios line is present in config file, it will be preserved and the software license will be okay. Some of admins are keen to clone ESXi boot device in order to speed up the deployment. ![]()
