moved vm from esx 5.1 to 5.5 unable to have more then 8 cpu cores

Jump to solution

Hi all

I had a VM on esx 5.1 that had 8 vcpu cores.

I moved it to a new host with esx 5.5. The new host has 16 physical cores so I want my VM to have access to all of them.

I fixed the license so now my VM should be getting all 16 of them. I can successfully create a new VM that has access to all the processor cores and power it on.

But when I tried to change my VM settings I am still  getting the same number of cores: 8. 

I don't have vCenter. The move was accomplished by copying the vmx and vmdk file over to the new host and right clicking on the .vmx and selecting "add to inventory".

has anyone seen this before?

Thanks

OK

so upgrade your hardware at lest to version 9 (vmx-09).

If you create snapshot before upgrade you can revert all changes if you want so I would try to go for HW version 10.

When you edit your VM what is selected for OS under Options tab ->General Options?

Hi TPT,

which license of an ESXi server are you using?

For FREE Hypervisor you can have max. 8 vCPU per VM.

OK, just for check:

- which hardware version you have on this VM?

- which operating system is installed inside?

- which OS is selected under General Options for that VM?

Thanks

1. hardware version is 7, i do not want to upgrade to 10 because I don't have a vcenter. Can I upgrade to only say 8 or 9?

2. OS is SUSE 11 SP1, 64 bit.

3. unknown, I did not create this VM.

The OS listed is SUSE10 64bit, i will now change that to 11 since this obviously do not match what is really on there.

do you have your host properly licensed/ ie. properly assigned license?

What you see in host Configuration tab -> Software under Licensed Features?

Did you try changing the number of vCPUs by connecting to the ESXi host directly?

Download VMware vCenter Converter Standalone for P2V Conversion
