Quiescing Virtual Machines

A process that pauses I/O operations on virtual machines to minimize data loss during cloning. It ensures consistency while creating a copy.

Cloning Encrypted VMs

Cloning an encrypted virtual machine does not allow changing the storage policy. You must consult vSphere Security for guidance.

Prerequisites for VM Cloning

Before cloning a virtual machine, ensure you have the necessary permissions and resources. Stop any load generators running on the source VM. You must have the permissions to clone, edit, and configure virtual machines, allocate space, and assign networks.

PMem Resource Requirement

If the source virtual machine has an NVDIMM device or virtual PMem hard disks, the destination host or cluster must have available PMem resources. Otherwise, cloning cannot proceed.

Study Notes

vSphere Virtual Machine Administration

  • vSphere Virtual Machine Administration details creating, configuring, and managing virtual machines in VMware vSphere.
  • Virtual machines function like physical hardware, but are more portable, secure, and manageable.
  • VMware vSphere 8.0, ESXi 8.0, and vCenter Server 8.0 are supported.
  • Refer to VMware by Broadcom website for current documentation.
  • vSphere Virtual Machine Administration describes how to create, configure, and manage virtual machines in the vSphere environment.
  • Memory resources cannot exceed the virtual hardware configured memory size.
  • ESXi networking facilitates communication between VMs on the same host, different hosts, and between virtual and physical machines.
  • You can change the number of CPUs allocated to a virtual machine and configure advanced CPU features, such as the CPU Identification Mask and hyperthreaded core sharing.

Virtual Machine Files

  • Virtual machines comprise multiple files on a storage device.
  • Key files include:
    • Configuration file (.vmx): VM settings.
    • Virtual disk files (.vmdk): Disk characteristics.
    • NVRAM setting file (.nvram): VM BIOS/EFI config.
    • Log file (.log): VM activity logs. (Multiple older log files [.log-#] exist for historical details.)
  • VM configuration is manipulated through the vSphere Client, ESXCLI, and vSphere Web Services SDK.
  • Do not modify/move/delete these files without VMware support staff instructions.
  • Additional files are created during VM tasks.
  • Snapshots are not supported with DirectPath I/O devices.

Virtual Machine Hardware (Examples)

  • VMCI Device: High-speed communication channel between VM and hypervisor. Cannot be added or removed.
  • NVMe Controller: Non-Volatile Memory Express; PCI Express (PCIe) storage.
  • NVDIMM Controller: Accesses non-volatile memory on the host.
    • NVDIMM Devices: Non-Volatile Dual In-Line Memory Modules; up to 64 can be added.
  • TPM Device: Trusted Platform Module; guest OS use for sensitive data storage and verification.
  • Virtual Precision Clock: Access to system time on the ESXi host.
  • Virtual Watchdog Timer: Monitors VM performance and restarts if issues arise.
  • vSGX Device: Virtual Intel® Software Guard Extensions for enhanced VM security.
  • Virtual Shared Graphics Acceleration (vSGA): Introduced in a recent update.
  • PCI Controller: One PCI controller is presented for communication. Cannot be configured or removed.
  • PCI Device: Up to 16 PCI vSphere DirectPath devices are allowed, reserved for passthrough.
  • Serial Port: Interface for connecting peripherals. Configurable for physical port, host file, network connection, and direct VM-VM connection. Up to 32 can be configured.
  • Parallel Port: Connects peripherals to a file.
  • SATA Controller: Provides access to virtual disks and optical drives as a virtual AHCI controller.
  • SCSI Controller: Allows access to disks, appearing as different controller types (e.g., LSI Logic). Configurable type and bus sharing. Paravirtualization is available.
  • SIO Controller: Controls serial and parallel ports, floppy devices, and system management. One is available. Cannot be configured or removed.
  • USB Controller: USB 1.x/2.0 function.
  • USB xHCI Controller: USB 3.0 function.
  • USB Device: Supports various USB devices (security dongles, mass storage). Connects to ESXi host or client.
  • Chipset: VMware uses proprietary devices based on specific chips (e.g., Intel 440BX AGPset, Intel 82371AB).
  • DVD/CD-ROM Drive: Installed by default; configurable to connect to client devices, host devices, or datastore ISO files.
  • Hard Disk: Stores VMs OS, program files, and associated data; a large physical file or set of files.
  • IDE 0, IDE 1: Two IDE interfaces presented to the VM by default.
  • Keyboard: Provides input from VM consoles.
  • Memory: Virtual hardware memory size limits memory for VM applications. Intel SGX describes private memory regions (enclaves).
  • RDM disk: Allows storing VM data directly on a SAN LUN (instead of a virtual disk file).
  • PS2 controller: Provides access to virtual keyboard and pointing device via the PS2 interface.
  • Video card: Virtual graphics card for VM video acceleration.

Cloning Virtual Machines

  • Cloning options include:
    • Standard mode: All disks on a standard datastore
    • PMem mode: All disks on host PMem datastore; config files on a regular datastore.
    • Hybrid mode: PMem disks on PMem datastore, others on the original datastore.
  • PMem storage choice affects non-PMem disks.
  • Cloning a VM with NVDIMM devices or virtual PMem disks requires a destination host/cluster with available PMem resources.
  • Cloning steps: Start the Clone Existing VM wizard, choose a format, datastore, and select additional options if needed.
  • Cloning options have specific disk format choices (different pre-provisioning and other selections).
  • Cannot change storage policies when cloning encrypted VMs.
  • Cloning includes various options for customization (guest OS, hardware, and user settings).

Additional Information

  • Upgrading VMs, troubleshooting steps, required vCenter Server privileges, and more are covered in separate sections.
  • Topics on Guest OS installation, customization, and user mappings are included.
  • Methods to provision vSphere VMs are supported.
  • Creating a single VM provides a base for cloning.

vApp Information

  • vApp management, including creation, power operations, editing, configuring resources (CPU, memory, IP), and licensing.
  • Adding network protocols and assigning port groups/networks.
  • VMware vApp options activation/editing for VMs and configuring deployment options.

Guest OS Customization

  • Customization of guest operating systems during cloning or deployment using customization specifications.
  • Configuring user mappings (SSO).
  • Managing power states, startup/shutdown settings, and virtual consoles.
  • Troubleshooting methods, including identification of symptoms, problem definition, and testing solutions. Logging, debugging, swap space configurations, performance sensitivity, etc. are covered.

Cloning procedures and templates

  • Cloning VMs to templates preserves the original VM.
  • Templates can be modified and used to create additional templates or VMs.
  • Cloning or deploying from templates saves time for identical VMs.
  • Using templates or virtual appliances (OVF) for deployment is detailed.
  • Creating VMs with the New Virtual Machine wizard.
  • Cloning VMs to templates and VMs.
  • Employing various deployment options.
  • Selecting and utilizing existing templates, creating new templates, and utilizing different options (Standard, PMem, or Hybrid).
  • Customization options are available for guest OS and hardware during cloning.
  • Virtual machine options (General, Encryption, Power Management) with specific details about configuring VMs.
