Hi,<br />
My guess is that is does not change the MAC address but just to be safe:<br />
Can someone confirm me that doing a VMotion on a virutalisated Windows server do not change it's MAC address?<br />
<br />
One of my server is a FlexLM server and as you know, FlexLM licensing requires/incorporate the MAC address of the server. So, on a physical server, every time I would want to install FlexLM to another server I would need to re-register it with them. And if the network card fails on a physical server, I would also need to re-register. <br />
But with visualization, if I need to do a maintenance on the blade that holds my visualized windows server, I do a vmotion and move all vm running on that blade to other blades and that must not impact FlexLM.<br />
tx!

VMWare VMotion: do doing a VMotion on a virtualised Windows server changes it's MAC address?

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
