Before a running virtual machine can be migrated from one host to another there are some mandatory requirements that must first be met:
Hyper-V 2008 R2 must be deployed on both hosts. The first version of Hyper-V does not support live migration.
Source and destination Hyper-V hosts must be configured as a Failover cluster with shared storage enabled.
Source and destination systems must be using shared storage (i.e. via SAN or iSCSI configurations)
Source and destination systems must be running processors from the same manufacturer. It is not, for example, possible to migrate a virtual machine from an Intel based host to one containing an AMD CPU.
The virtual machine on which the migration is to be performed must be configured as Highly Available and to use Cluster Shared Volumes.
The virtual machine's Automatic Start Action setting must be set to do Nothing.
All Hyper-V hosts in the Failover cluster must be configured to boo…
This post is related to the issue what we faced today when we replaced the SSL certificates in our setup. When I launched the web-client and access the update manager tab, I get the message "interface
com.vmware.vim.binding.integrity.VcIntegrity is not visible from class
I started off by
restarting the VMWare vSphere Update Manager Service for the affected vCSA: 1. Log into vCenter
using the firstname.lastname@example.org account. 2. Home - System
Configuration - Services - Restart
This did not resolve
my issue... And we tried restarting all the services by SSH/Console into the
affected server and run the following commands: service-control
--start --all Still no luck. Make sure the certs are applied and it gets reflected in the config file. ( verify if the thumbprint matches) root@homelab71 [

The previous post talks about vSphere Integrated Containers and their benefits. The VIC offers a robust solution that enables the vSphere environment to quickly get containers up and running in their current vSphere infrastructure. This environment can be useful for migrating current apps to containers or for in-house development. Architecture
In a traditional container environment, containers run as threads within the container host. vSphere Integrated Containers leverage the native constructs of vSphere for provisioning container-based applications into its own container running its own very minimal Linux kernel with just enough code to run a Docker image, thus preventing any issue with containers being accessed from other containers by pushing isolation of the container down to the hypervisor layer that is much better at handling this type of isolation.
