![]() The following steps have been tested on a VMware vSphere ESXi 6.7 virtual machine running on a MacBook Pro. This post will show you how to prepare your hosts so that Ansible can communicate with them, allowing you to write playbooks for any kind of task you want to run. Or you could even automate the installation of Lets Encrypt SSL certificates on each host. Introductionĭid you know, it’s possible to automate admin tasks on VMware vSphere ESXi hosts with Ansible? For example, you might want to modify the hosts file on hundreds of ESXi hosts in your cluster. This guide shows you how to prepare an ESXi host, so that Ansible can be used with SSH Key-Based Authentication to automate administration tasks. Perfect for development environments and practice labs. ![]() Run Linux, macOS, vSphere and more on a single PC or Mac. That’s it, your VM is successfully migrated from VMware ESXi to Proxmox VE.Run Multiple Operating Systems on PC and Macĭownload VMware's Powerful desktop virtualization tool for Developers and IT Professionals. Here we have used VLAN ID 10 for Server LAN, use your VLAN-ID for tagged/trunk switchport type. # qm set 120 -scsi0 glusterFSname:120/vm-120-disk-0.qcow2Ĭonfig networking for the VM # qm set 120 -net0 model=virtio,bridge=vmbr0,firewall=1,tag=10 Import ntp-1-sparsed.qcow2 disk image into the VM # qm importdisk 120 /path/to/image/ntp-1-sparsed.qcow2 glusterFSname -format=qcow2 Let’s create a VM in Proxmox VE qm create 120 -name ntp-1 \ Upload the new sparsed disk image file to Proxmox VE Host Deploy VM in Proxmox VE from existing QCOW2 disk image Sparse the qcow2 formatted disk image file # virt-sparsify -tmp tmp -compress NTP-1.qcow2 ntp-1-sparsed.qcow2 To avoid temp directory size issue we are creating a tmp directory inside our vmdata directory and full permission for all users # mkdir /vmdata/tmp Install virt-sysprep tools in CentOS host # yum install -y /usr/bin/virt-sysprep Navigate to disk image directory and decompress the disk image file # pigz -v -d Ĭonvert file format from VMKD to QCOW2 # qemu-img convert -p -O qcow2 NTP-1.vmdk NTP-1.qcow2 You may install it by below command also # yum install -y qemu-img To convert disk image from VMDK to QCOW2 format we will need qemu-img utility which should be pre-installed in CentOS Virtualizations host. Note: If you have high speed network connections between servers you may skip compressing.Īfter completion of compression we SCP the Compressed disk image and metadata file to our Intermediate CentOS Virtualization host to convert and sparsify the disk image.Ĭonvert VMDK to QCOW2 and sparsify the QCOW2 disk image ![]() Here we find that we have such 2 files, NTP-1.vmdk (metadata) and NTP-1-flat.vmdk.Īs the Virtual Disk NTP-1-flat.vmdk has a bigger size we are going to compress it so that it would not cost us more time in transferring data from ESXi to the CentOS host. In ESXi it usages a metadata file and actual disk image names as IMAGENAME-flat.vmdk. VMware usages VMDK disk image format to store data. Navigate to VM directory and determine the virtual disk name Now shutdown the target virtual machine and check VM power status # vim-cmd vmsvc/power.getstate 19 Here we found the VM ID is 19 and it’s configuration file is located inside datastore2/NTP-1 directory. Or use grep to filter out unnecessary outputs We will also need to allow SSH Client to SCP disk image files from ESXi host go to Networking -> Firewall rules -> SSH Client in ESXi host portal. To enable SSH access in VMware ESXi please check this document. So, we will need shell access for all 3 hosts. ![]() In this article we perform all operation from command line interface. To import a virtual machine disk as thin provisioned and remove unnecessary disk space used by the disk image we will use another intermediate CentOS Virtualization host with qemu-img utility and virt-sparsify, pigz compression tool installed in it. Importing the disk image as thin provisioned would save some disk space and allow us to overcommit disk space between virtual machines. We can directly import the VMware disk to Proxmox Hypervisor but it will use the full disk size allocated for the virtual disk image. To learn more about Proxmox you may visit our other posts on Proxmox. So, we will change the image format from VMDK to QCOW2. We know VMware ESXi stores VM Disks in VMDK image format and for Proxmox we need QCOW2 disk image format. We have RAID5 disk array as datastore for our older ESXi hypervisor and Gluster FS Replicated Storage as shared storage in Proxmox Cluster. We are migrating a virtual NTP Server from our old ESXi to new Proxmox Cluster. We have scheduled downtime for this migration process. Today we are not working on our lab environment but on production environment. Hello dear readers, today we are going to migrate a virtual machine from VMware ESXi to Proxmox VE.
