Hi - After upgrading my host to ESXi 6.5 and VCSA to 6.5 I have found that one of my VM's shows all memory being utilized in the summary screen and when checking the performance chart for percentage used it displays 100% (This is not the case when checking task manager in Windows)
Consequently the vSphere web client complains about memory usage for this VM.
I have 20+ other VM's on 2012 R2 that are not experiencing this problem. The only difference I can see is that this particular VM has passthrough enabled for the LSI card.
The VM has no reservation set and the limit is set to 'unlimited'. If I set a reservation to match the total memory size the problem still occurs.
The VM in question runs Server 2012 R2 with an LSI 9260-8i passthrough.
Latest VMware Tools is installed.
I have rebooted the VCSA, the host and the VM.
This issue was not present on ESXi 6.
