Hi,

When trying to pin a VM CPU's to Physical CPU's, I'm getting this error in case the number of physical CPU slots are > 35 (e.g. 40):

Error attempting to pin CPUs.
Full error: Fault reason is "Operation Failed". Fault detail is "[size must be between 0 and 4000, Attribute: vmStatic.cpuPinning]". HTTP response code is "400". HTTP response message is "Bad Request".

It is working for me up to 35 physical CPU's. but above it, I get that error.

Can you please tell what this error means and how to overcome it?
Version we are using is: 4.3.6.6-1.0.9.el7

You've specified a pinning-string that is longer than 4K characters - the pinning string shouldn't be that long..

Thanks,
Lavi
