I am running ESXI 6.5 and have a PCI USB3 card enabled for pass-through to a VM I use to run Veeam backup. The VM has all it's memory reserved because of the pass-through. I'm constantly getting Virtual machine memory usage alarms for this VM. It isn't heavily using the memory though. Any suggestions?
I ran into a similar issue where quite a few VMs started barking about memory usage. I ended up upgrading the virtual hardware and VMware Tools. That seemed to resolve the issue.
Unfortunately I've already done that and the issue persists.
