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 Thanks, Lavi

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

Hi Arik, I'm using this tool to pin the VM cpu's: olvm-vmcontrol -m <ENGINE> -u api_cpu_pin@internal -v <VM> -c setvcpu -s 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55 -e Thanks, Lavi

So there's probably a bug in that olvm-vmcontrol thingie, I don't know how it generates the pinning string You can write your own script to generate a shorter one :) or update to 4.4 and use the auto-pinning feature

Hi Arik, You are right. I tried this syntax and it worked: olvm-vmcontrol -m <ENGINE> -u api_cpu_pin@internal -v <VM> -c setvcpu -s 0-19,40-59 -e (Pinning to 40 Physical cpus). Will see how to convert a long list of digits to the shorten syntax... Thanks, Lavi
