Is new Player version v14 compatible with Intel Core i5 2400 Sandy Bridge?

As far as I have read the new Player version v14 has some more requirements for the used CPU.

Does that mean that an Intel core i5-2400 Sandy bridge does not work with v14?

That would mean VmWare player v12.5.7 is the last version for this kind of CPU.

I experienced difficulties when installing the new v14.

If v14 does not work I would have expected a warning popup: "CPU not supported for this Player version"

... but no warning appeared

Processor requirements are located at: Processor Requirements for Host Systems

It appears that the processor you have is not supported in v14.

Sandy Bridge supports VT-x with Extended Page Tables, so it is supported.

Hi,


The installer is currently not aware of the CPU requirements by Workstation 14.

Your CPU is from 2011 and that makes me think it does not have support for the VMX Unrestricted Guest feature.

Unfortunately intel's CPU feature pages do not mention if the CPU does or does not support it.

I wrote a small .iso that you can burn to a CD and boot your host from to see if it supports Unrestricted Guest.

See this post of mine:

Re: @VMware Workstation Product manager : please publish the necessary vmx-file hacks that are requi...

Intel EPT support and VT-x is indeed also required, but without UG support that still isn't sufficient.

edit: some more technical details

VMware Workstation 14 and Fusion 10 have new CPU requirements, one of these requirements is Unrestricted Guest Mode.

In an earlier post user bluefirestorm pointed out correctly that you can see in the vmware.log of a VM running under any earlier but recent Workstation if a CPU supports Unrestricted Guest Mode, see his post here: Re: Read Me if you have a Intel Xeon CPU


quote from that post:

The Intel ARK site does not have an option in the Advanced Search to look for processors "Unrestricted Guest" feature.

But from what I can see in the Intel Developer Guide, the Unrestricted Guest feature is identified by MSR 485 bit 5 set to 1.

2017-07-25T04:58:26.927+02:00| vmx| I125: Common: MSR       0x485 =             0x401c5 

If we take this example and look at the last two bytes in hexadecimal then we have: Hex:

C5 

which is in binary:

11000101 
bit 7  6  5  4  3  2  1  0
     1  1  0  0  0  1  0  1
             ^
             |

So in this case, the bit 5 is 0 so the Unrestricted Guest feature is not available.

On linux one can use the following command line to quickly extract those two bytes:

 cat vmware.log | grep "MSR\s*0x485" | awk '{print $NF}' | sed 's/^.*\(.\{2\}\)$/\1/' 

Shows last 2 characters

There's also a little .iso file I authored that you can burn to a CD and boot your physical machine from to test if your CPU has unrestricted guest support. See: https://communities.vmware.com/message/2709089#2709089

Granted, wikipedia isn't necessarily the final say on matters, but check out x86 virtualization - Wikipedia .  VMX Unrestricted Mode was introduced in Westmere, the generation preceding Sandy Bridge.  I can't say if Intel included that functionality on every I5 model, but I haven't been able to find anything that indicates that they did not.

Hi Jadams100,

Right.. the VMware specifications page has been updated to say 2011 processors and newer (I might misremember 2012)

Windows VM | VMware Workstation Pro

Still not sure on if his processor supports it though, it's a bit of an edge case and as Intel isn't really listing this feature for their processors at the Ark site, your guess is certainly as good as mine.

Which is why I pointed to a few ways on figuring out if the processor actually supports this or not.

This whole "we changed the CPU requirements for VMware desktop products is frankly a bit of a mess" to say it mildly.

TS: Can you clarify what actually was the problem when you state:

I experienced difficulties when installing the new v14.

Hello,

I have the same processor.

Did it work with Workstation 14 or not ?

You said you had problems, but then said it installed with no complaints ?

Is that correct ?
