This colleague was trying to perform a Storage vMotion operation on a VM that also had a RDM attached and was running into a problem where the operation was failing because the destination datastore did not have sufficient space. The vMotion process has become so refined that even in tests at trade shows involving hundreds of thousands of virtual machines vMotion migrations never lost a VM or distupted a VM's services. Please check your VMotion network settings Example 2: The VMotion failed because the ESX hosts were not able to connect over the VMotion network. No reason was given as to what caused this in the first place. If you have properly setup and configure the share storage for your vCenter/ESX hosts, vMotion just move a VM from one host to another, when the process fails, the VM should be fine without any problem and it should remain where it was on its source host. Most of the tests for vSphere 5. Encrypted vSphere vMotion supports all variants of vSphere vMotion for unencrypted virtual machines, including migration across vCenter Server systems. Key Features. For more information, see VMware VMotion fails if target host does not meet reservation requirements (1003791). You can use vMotion to migrate virtual machines to a different host and datastore simultaneously. A vMotion request is first sent to the vCenter, which then co-ordinates between the source and target ESXi hosts to complete the vMotion. VMware VMotion enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. Host vMotion fails with "source detected that destination failed to resume" I have searched the internet high and low for some information on this error, the virtual machine fails at 82% during host migration.

If you have a environment where you have 2 or more dedicated uplinks reserved for vMotion you can double the total bandwidth available by using this option. If vMotion would pump the entire disk hierarchy across the vMotion network it would steal bandwidth from the I/O mirror process and this will hurt the performance of the virtual machine. The successfully vMotioned VMs can have more/less CPU, RAM, storage than the failed VMs. Which is weird and something I’ve never seen before. This utility allows users to easily migrate virtual machines in bulk from a graphical user interface between vCenter servers using the Cross-vCenter vMotion feature.
