I see that there have been a number of folks that have this error and adjusting the memory reservation for the VIM under System Resources has fixed this problem, but not for me. My reservation setting in the VIM process is '0'. Vitals:
Dell T110 II Server
4GB RAM
Intel Xeon CPU E31220 @ 3.10GHz
4 CPU Cores
500 GB hard drive
ESXi version 5.1
One Linux VM with 4GB RAM allocation, 2 CPU cores and 45 GB of storage.
Error I get upon attempted start:
Failed to power on VM.
Could not power on VM: Admission check failed for memory resource See the VMware ESX Resource management Guide for information management settings.
Group vm.4757: Invalid memory allocation parameters for VM vmm0:Mitel_Applications_Suite. (min: 524288, max: -1, minLimit: -1, shares: -4, units: pages)
Group vm.4757: Cannot admint VM: Memory admission failed. requested reservation: 536579 pages
I have changed the VM memory all the way down to 1GB, no change.
I have played around with the VIM memory allocation, no change.
One interesting fact is that the Resource Allocation for the host tab shows memory @ 1747MB Capacity, Reserved Capacity @ 0MB and Available Capacity @ 1747MB, but I have 4GB of RAM and the vSphere Client does show that under the Configuration tab.
