Vmware : Clonning From Physical To Virtual
Recently I've consider roughly problems of converting a CentOS v.5.0 into VMWare ESXi v.6.7, this is peculiarly due to the tool (vCenter Converter Standalone) doesn't back upwards CentOS v.5.0
So, instead of installing a build novel CentOS v.7.0 in addition to migrate all the Oracle database into the novel VM (Virtual Machine) manually, I proceeded to "clone" the physical machine.
There are roughly considerations earlier proceeding, the physical server's hardware specifications. How much RAM was installed, how many "Logical Array" is using. This volition deport upon the creation of the VM, every bit such the ESXi server (host) must get got sufficient hardware to back upwards such a move.
The procedure is relatively easy, every bit this is done through "Direct Console Login", I was non able to render the screenshots due to safety issues. But withal this are the steps I've taken in addition to was successful.
Assumption :
a) The existing physical server (CentOS 5) hardware is two x NICs, 8GB RAM, 300GB x two RAID1, 300GB x two RAID1, 600GB x two RAID1.
(Note : a full of Three (3) logical drives was present, this business office is of import at the subsequently stage).
b) External USB 2TB or to a greater extent than HDD.
The Steps-by-Steps :
1. Download the latest version of CloneZilla. At fourth dimension of writing, the latest stable version v.2.6.2-15 in addition to the edition I've downloaded is (i686, ISO) which is compatible amongst the server's hardware.
2. Using your preferred ISO burner, dismiss a bootable CDROM disc in addition to you lot mightiness desire to label it for slowly references.
3. Shutdown the CentOS v server past times running ascendence : shutdown forthwith -h
4. Insert the CloneZilla bootable CDROM disc in addition to plugin the External USB HDD into the CentOS v server.
5. Power-up the server in addition to Press --> [F12] key.
* Note : Your server mightiness get got unlike cardinal for invoking the "Boot Menu".
6. Select booting from the CDROM elbow grease in addition to hold off for CloneZilla to kick automatically.
7. Follow the on-screen instructions, similar linguistic communication & keyboard selection.
8. Next is to select --> device-image option.
9. Then select --> local_dev option, in addition to so it volition prompt you lot to press [ENTER] cardinal to continue.
10. At the adjacent screen, you lot volition move shown a listing of all the local drives & external USB drives detected. Just press [CTRL] + [C] to continue. You involve to ensure the external USB HDD is detected correctly.
11. Next concealment is to select "Home/PartImg" location, which inwards this illustration is the external USB HDD drive.
12. Next concealment when prompt, simply select --> OK push to continue, in addition to so it volition prompt you lot what is the work you lot wanted to perform, inwards this illustration nosotros select --> save_disk option.
13. Next it volition prompt you lot for the image's filename, pose a cite that is unproblematic & slowly to call upwards (eg. svr_centos5_28Jul19), adjacent is to ensure the icon file size is unlimited, type --> 1000000 to ensure Clonezilla volition non split upwards the file according to 4GB limitation.
14. Leave the compression every bit default at either Z0 or Z1, of course of written report you lot tin get got higher compressions but since I get got a 2TB drive... so non a problems.
15. Next is the encryption prompt, this all depends on you. But every bit I'm the only 1 soul in-charge & I practise non involve to maintain the icon after restoring, I volition not encrypt the icon files.
16. When prompted, simply press --> [Y] to offset the clonning process, this may takes a few hours (mine took me fourteen hours) in addition to select --> Shutdown when completed.
Note : More information tin move constitute at Clonezilla website, delight practise watch their website.
17. Once all is completed, nosotros volition move moving the VMWare server. First nosotros involve to practise VM in addition to all the configurations must fit precisely every bit the CentOS v server, such 2 x NICs, 3 x Drives & 8GB RAM.
18. For the choice of Guest OS, I've selected --> CentOS 4/5 64-bit version.
19. Also I've configured the CDROM to purpose an ISO icon file instead of the host's drive. I involve it to kick into CloneZilla for the icon restoration.
20. Next is plugged inwards the external USB HDD into the host server in addition to add together a "USB Device" inwards the VM, this is to ensure the elbow grease is detected properly.
21. The next is kick the VM into CloneZilla in addition to offset restoring "restore_disk" process, move out everything every bit default volition do.
Oh, you lot mightiness desire to select --> "Skip checking root image" choice & "Shutdown" after complete.
22. Before power-on the VM, you lot involve to remove the external USB HDD from the settings in addition to also the ISO file.
23. Just power-on the VM similar normal & await out for whatever irregular warnings or critical messages. But hence far I've didn't consider whatever fault messages or similar in addition to everything simply plant every bit it was supposed to.
!!! HAPPY COMPUTING !!!
