VmDirectPath + vMotion in VCP410?

[threegloriousse]

Hello everyone,

perhaps this question has been already answered, but at the moment I'm unable to find it.

What would be the correct answer along the recent VCP410-Blueprint 1.9.2: Can a VM with VMDirectPath enabled be vMotioned or not?

Thanks inadvance for your answers.

Welcome to the community.

In vSphere 4, no a VM cannot be vMotioned if configured with a VMDirectPath I/O device.

Hello Scott,

thank you very much for your answer. I was a little bit confused about this question, because there are some bloggers who claimed that VMDirectPath and USB Passthrough are supported for vMotion since the release of vSphere 4.1

but I was unable to prove this in the official VMware documentation.

The VCP4 exam only contains items which apply equally to 4.0 and 4.1, so anything that is specific to 4.1 will not be included.

Hello Scott,

please forgive me, but that confuses me even more . If there is no exception to the rule you mentioned, than i.e. the answer to the following question must be always 'No'  or the question cannot be asked in the VCP410 at all: "Does vCenter Server 4.x require a 64-Bit operating system?"

That leads me  to another question: Why is the blueprint based on the 4.1 documentation? Again, if there is no exception to the rule you mentioned, than one has to check every feature and requirement in the most recent documentation if it is version agnostic. Am I right here or totally misled?

The exam items are all 4.x, neither specific to 4.0 or 4.1. You can technically study from the 4.0 or 4.1 documentation, but the blueprint was updated to refer to the 4.1 documents as it makes sense to study using the latest software and documentation. VMware could have updated the blueprint to include 4.1-specific features, but they never did.

You don't need to worry about what is different between 4.0 and 4.1, just study using whatever software and documentation you have, using the current blueprint as a guide to what you'll get tested on, and you'll be fine.
