ESXi 5.5 the fault tolerance configuration of entity has an issue: The virtual machine has more than one CPU.

I am having trouble to resolve HA error, when I am configuring virtual machine fault tolerance, I get error " The fault tolerance configuration of entity has as issue : The Virtual machine has more than one CPU."

I am using ESXi 5.5 with vCenter 5.5.

In ESXi 5.5, fault tolerance is only available for uniprocessor VMs.  Fault tolerance for SMP VMs (with up to four processors) is supported in ESXi 6.0.

Thank you for quick answer.

It is enable on some virtual machine in same cluster and now I craeted new machine and has this yellow triangle on it, i am trying to resolve it, i do not wanted to clear warning message , but wanted to resolve issue. so in future, I don't get issue, when I am updating host. how to resolve it. or how do I find out about processor.

check your guest configuration, it might have 1 vCPU with multiple cores, it needs to be 1 and 1
