![]() ![]() Rescue disk – this may be necessary for the recovery of the system once the disk data has been converted over. This can be gleaned from the df output and the content of /etc/fstab. Partition layout -know exactly the partitions, sizes and FS types. Blocks are in 1KB units, do the math to figure out the equivalents in MB by dividing by 1024 and in GB by dividing by 1024 again. You may also have multiple disks (hdb, sdb, etc).ĭisk size – use a command such as sudo sfdisk -s. How much physical RAM? Is it over or under-utilized?ĭisk type – IDE or SATA and the disk device will be /dev/hda, SCSI will be /dev/sda. Consider the follow aspects of your system. You will want to have the necessary tools in place as well as some calculations. Good ol’ dd + netcat, followed by rescue disk of some kind (to fix the modules and make a new initrd). UltimateP2V appears to be worthy of consideration. ![]() These products or methods offer full support for Linux… Liveview looks promising, however it only runs on Windows (due to dependency on VMDK disk mounter) and works with vmware-server, not ESX server. PowerConvert works (somewhat) with Linux but it does not support LVM and in my experience is an unreliable product with lackluster support. –update – VMware Converter 4 will do a live P2V for Linux. It is most useful if your target for migration is ESX 3.x This is due to the fact that it just does a raw block-by-block copy of the source disk. VMware converter will work, however any options such as resizing the disks and post migration configuration are greyed-out. These products do support Linux in some way… The following software products claim to do P2V, but in fact do not support Linux, so don’t bother. ![]() Other distributions can of course be converted but the exact steps will vary. The focus of this P2V explanation is on Red Hat and CentOS guests as they are not only supported, but benefit from kudzu and rescue disk capability built-in. The same steps should mostly apply to VMware Server, Workstation or even QEMU. This page describes some of the usual steps necessary to convert a Linux system into a virtual machine running under VMware ESX Server. In other words, it is the process or procedure of moving a running system (operating system and everything installed) from a physical machine to a virtual machine. P2V Linux migrations are a combination of science, art and luck. ![]()
