Does free ESXi support multi-cpu?

I have an Intel Core 2 Duo box that I loaded ESXi on. No problem. When I applied the license file, it states that only 1 socket and 1 cpu is supported. Is this expected?

TIA

Unless you have 2 processors (multiple Core 2 Duo), you are setup correctly.

I setup the free version of ESXi on an IBM x440 (4 proc) yesterday, and all processors reported properly.

Keep in mind, that processors are recognized (at the licensing level) by the socket, and not the number of cores.

Yes, ESXi can be loaded on SMP hosts and can run vSMP guests (up to 4 vCPU)

In addition to what Jase says... when you apply for the free ESX3i version, one of the questions you need to fill in is on how many CPU's you are planning to install this.

The way I read it was as processors on the same motherboard, not as isolated installs. Besides what use is vSMP support if you have only one physical processor (even with 2 cores) ?

So the answer is YES, it supports multi-CPU, and you can specify details for what you need during the registration process.

In Inventory -->; Config, it shows the following under processor:

Model: Core 2 Duo

Processor Sockets: 1

Processor Cores per Socket: 1

Logical Processors: 1

Hyperthreading: Disabled (Not active)

Licensed Features --> ESX Server Edition, shows:

ESX Server Standalone

Up to 4-way virtual SMP

Licensed for 1 CPU

Doesn't seem right to me...

Not sure why it isn't seeing your other cores. But I haven't had the opportunity to install ESXi on a Core 2 Duo system as of yet.

I would think the Processor Cores per Socket would read 2 or 4, depending on your CPU. And I would assume the Logical Processors would be the same.

What type of box is it?

What's the specific processor model? I have a E6750 and it properly is shown with 1 socket / 2 cores / 2 logical.

Hello all,

I think i may be seeing a similar issue, like the one reported.

I'm using an Gigabyte EP45-DS3R + Intel E7400 running ESXi update4. I have all my VM's up and running but esx recognizez only 1 core, or at least, i think that is what it means.

here's what the report from esx says

General

Manufacturer:

Gigabyte Technology Co., Ltd.

Model:

EP45-DS3R

Processors:

1 CPU x 2,796 GHz

Processor Type:

Intel(R) Core(TM)2 Duo CPU E7400 @ 2.80GHz

Processor sockets: 1

Processor cores/socket: 1

Logical Processors: 2

Hyperthreading:Enabled

The summary screen displays the total amount of Mhz being just 2,8Ghz, and i'd be expecting it to tell me i have 5,6=2x2,8.

Can anyone shed some light on this confusion?

Thanks,

Ionut

I wonder if the BIOS is set to show a single logical CPU for some reason. I'd reset the BIOS to factory defaults and then ensure hardware virtualisation is enabled, for starters.

I think it sees 2 logical cpu's, but just 1 core...which is what i don't understand to begin with, i was expecting 2 cores to be visible, as i'm not sure what 2 logical cpu's means (thinking it may be related to HT?)

I checked the bios, there are no settings regarding virtualization enabling. The CPU does not have intel-vt, BUT as i understood it, that only means i can't use 64b OS's, which seems unrelated to the number of cores visible to me.

any other thoughts?

thanks,

ionut
