The Non Traditional Way to clone from Linux/Ubuntu Desktop/Laptop to VM VMware Workstation.

 The Non Traditional Way to clone from Linux/Ubuntu Desktop/Laptop to VM  VM = VMware Workstation. Reason :  I tried CloneZilla or Traditional DD commands. it was taking lot of time and was confusing. The method shown here is working for me. It may or may not for you. Steps :  1 - Create same version OS VirtualMachine on VMware workstation. this will create : fat32 - boot ext4 - OS image partition. 2 - Go to the system you want to clone ( having same version ) boot from live cd or USB boot into live cd. Reason : we need to unmount the HDD/ partition. use Gparted copy the ext4 partition from Laptop/desktop and paste it on the pendrive partition. i had created ext4 partition on the pendrive. so i did ext4 to ext4 . 3 - Boot VirtualMachine with live cd , copy the same disk ext4 files to the ext4  partition on the VM OS, by booting into live version on VM.not on regular boot. To boot into live version , you need to use few softwares 1 - Live CD as iso or live cd. 2 - Boot order setup optio

16 - What’s the main difference between an interactive ESXi installation and a scripted installation?

17 - What is the first thing to check when having a problem installing ESXi?
Ans -  Make sure the hardware clock is set to UTC and the NX/XD bit is enabled in the BIOS.

18 - Name 5 of the 10 bits of information required when installing ESXi?
Ans -  Keyboard Layout, VLAN ID, IP Address, Subnet Mask, Gateway, Pri DNS, Sec DNS, Host Name, Installation Location, Root Password.

19 - What type of technology does VMware fault tolerance use?
Ans -  VMware FT uses a technology called vLockstep.

20 - What is VMware vMotion and what are its requirements?
VMware VMotion enables the live migration of running virtual machines from one physical server to another with zero downtime.

VMotion lets you:
• Automatically optimize and allocate entire pools of resources for maximum hardware utilization and availability.
• Perform hardware maintenance without any scheduled downtime.
• Proactively migrate virtual machines away from failing or under-performing servers.

Below are the pre-requisites for configuring vMotion :
• Each host must be correctly licensed for vMotion
• Each host must meet shared storage requirements
• vMotion migrates the VM from one host to another which is only possible with both the host are sharing a common storage or to any storage accessible by both the source and target hosts.
• A shared storage can be on a Fibre Channel storage area network (SAN), or can be implemented using iSCSI SAN and NAS.
• If you use vMotion to migrate virtual machines with raw device mapping (RDM) files, make sure to maintain consistent LUN IDs for RDMs across all participating hosts.
• Each host must meet the networking requirements
• Configure a VMkernel port on each host.
• Dedicate at least one GigE adapter for vMotion.
• Use at least one 10 GigE adapter if you migrate workloads that have many memory operations.
• Use jumbo frames for best vMotion performance.
• Ensure that jumbo frames are enabled on all network devices that are on the vMotion path including physical NICs, physical switches and virtual switches.
