![]() The first kills crond, the second adds the new cron job to the root crontab file, ad the third restarts crond: # At the end of the file, add 3 lines (using "G" then "O" in vi). # Edit /etc/rc.local.d/local.sh, using a command such as "vi /etc/rc.local.d/local.sh". # Run the command "kill $(cat /var/run/crond.pid)", This will kill the process crond. # To run this script on a regular basis, without user intervention, do the following : # Disable networkcards on connecting at startup # Create a clone of a running machine on ESXi, without vCenter services available This is still in a testing phase, but here it goes: I wrote a script running on the box itself. Other ways (PowerCLI as well as ESXi CLI) are specified by vNEX.Īlthough this post was answered, I think this reply will be usefull for anyone searching to clone a VM on a ESXi box, without having vCenter and not wanting to shutdown the source vm ![]() If you have vCenter server you can manage multiple ESXi host (Either through vSphere client or web client) Features such DRS, DPM, SDRS, SIOC, HA, cloning, snapshots, templates etc. Note that vCenter will give you lot of features to manage your virtual environment. However, you need to have valid vCenter license. Yes, if you want to clone Virtual machine, easiest way is to install vCenter server & connect to vCenter server using vSphere client or web client (its new user interface). In you case, you are using vSphere client to connect to individual ESXi host. Hence you can use vSphere client to connect to ESXi host as well as vCenter server. When the server is an ESXi host, the vSphere Client displays only the options appropriate to single host management. When the server is a vCenter Server system, the vSphere Client displays all the options available to the vSphere environment, according to the licensing configuration and the user permissions. The vSphere Client user interface is configured based on the server to which it is connected: a server migration, be sure to select “I moved it” when the destination hypervisor asks during first start up of the newly copied virtual machine.The vSphere Client is the principal interface for administering vCenter Server and ESXi. If you intend to use just your destination virtual machine, and never start up the source virtual machine again, i.e. Once the virtual machine copy is complete, you can go to the destination server, register the virtual machine files, and boot up the VM. This happens automatically so you do not need to babysit the copy process. Every so often the SSH connection will renegotiate the connection. You can watch the virtual machines copy process on the SSH client. Scp -v -c aes128-ctr -r * the syntax is correct, the SSH client will now prompt for the destination server’s root password. Navigate your SSH client to the source virtual machine directory.Ĭhange datastore1 to machine the name of your source VMFS device, and VMNAME to the name of the virtual machine you’d like to copy. A connection to the destination hypervisor is not needed, however SSH needs to be enabled and running on both servers. I opened up my trusted Putty installation.Ĭonnected to the source hypervisor. You don’t want them running during the copy, as this will most definitely make your destination copies corrupt. Make sure the virtual machines on the source hypervisor are now powered off. The next step, on the destination hypervisor, create the necessary root folders in the VMFS store you want to copy the virtual machines to. I was trying to utilize as much bandwidth as possible, which did work… but the RAID card became my bottleneck. ![]() ![]() You do not need to setup a special NIC for a direct SSH transfer. I did not remove the management network from the NICs that were still connected to the primary network, as I would need to access the servers from my workstation. I setup some virtual switches on each and gave them static IPs in the same subnet. So, lets copy the virtual machines directly via SSH!įirst, I took an ethernet cable and used an used NIC interface on both servers to make a direct connection. ![]() Watching the virtual machine copy is like watching grass grow, and I didn’t want to use the rest of my life to do it twice. Now, copying almost a terabyte sized virtual machine from 5.1 to a NFS storage folder, and then have to copy the virtual machine again from the NFS storage folder to 6.7 would take absolutely forever. The ESXi version 6.7 server would not mount the 5.1 version VMFS drive. For some reason, my go-to method wouldn’t work. There are a couple ways to do this, some ways harder than others. The other day I needed to transfer large virtual machines from a VMware ESXi 5.1 install to a 6.7. ![]()
