"Insufficient Resource" error configuring a VM's virtual pmem device capacity equal to the available host pmem
Symptoms
When configuring a VM with virtual
PMem, the size of the virtual pmem device cannot be as large as the
remaining pmem capacity on the host itself, due to overhead requirements
for pmem virtualization. You will receive an "Insufficient Resource"
error if you exceed the maximum virtual pmem device size.
Cause
Due to virtualization of PMem
management overhead, a virtual pmem device cannot be configured to
consume the entirety of the available pmem on the host.
Resolution
To resolve this issue, configure the size of the virtual pmem device to be less than the available physical pmem on the host.
The overhead for a virtual pmem device varies based on the configured size, but should be around 1.5 - 3 percent of the virtual device size.
