we have a little strange behaviour on our platform, which might be an configuration issue but we dont know. The behaviour is as follows: We recently integrated a new ESXi Host into our existing vSphere 6.5 VCSA Cluster. Whenever we power on a virtual machine it is being started on exactly this new ESXi-Host. Of course when recently intergrated ressources where free, but now the RAM is 99% and vSphere still decides to power-on a new virtual machine on that host, but there are others with less overall CPU, RAM usage.
This is how we have setup DRS:
Maybe someone has an idea where our configuration fault is, we currently did a manual load-balance by migrating virtual machines and turned DRS Automation to Manual, so virtual machines keep where they where last booted.
Thanks for your help in advance!
had the same problem some month ago (after upgrading to 6.5)
Was able to fix it by changing the advacnced cluster settings.
Take a look in the discussion below:

Please try the steps provided in below discussion:
n the web client, Configure tab, Services, vSphere DRS: In the Advanced Options / Configuration Parameters section, add these two parameters.
Change is immediate, no further action required.
