Today i am shring an important information of files being used by Virtual Machines. And can play a important role to troubleshoot Virtual Machines using in ESX, ESXi, Virual Machine Workstation or Webserver etc…
|VMware Virtual Machine Files|
VMDK files – VMDK files names as (Vmware Virtual Disk file) are the actual virtual hard drive for the virtual guest operation system . You can create dynamic or fixed virtual disks. With dynamic disks, the disks start small and grow as the disk inside the guest OS grows. With fixed disks, the virtual disk started out at the same (large) disk size decided initally while creating VM.
Log files – Log files are just that- a log of VM server activity for a single virtual server. Log files can be used only while doing any troubleshooting with a virtual machine.It can be more than 1 or 2 and modified each time while we Start, Suspend or reboot the Virtual Machine.
VMX files – a VMX file is the primary configuration file for a virtual machine. When you create a new virtual machine and answer questions about the operating system, disk sizes, and networking, those answers are stored in this file. As you can see from the screenshot below, a VMX file is actually a simple text file that can be edited with Notepad.
VMEM – A VMEM file is a backup of the virtual machine’s paging file. It will only appear if the virtual machine is running, or if it has crashed.
NVRAM files – These files are the BIOS for the virtual machine. The VM must know how many hard drives it has and other common BIOS settings. The NVRAM file is where that BIOS information is stored.
VMSS files – A VMSS file is Vmware Suspended virtual machine state and it is created while you suspend any Virtual machine . its stores the information of the running application while suspending the machine.
VMXF Files – A VMXF file is VMware team member file which creates when you create any Virtual machine and its shows the information about the client MetaData Attributes & VMID.
