This is a display error in esxtop. The vm-vmm group's swap values should be rolled up into the VM group's swap values.
This issue is resolved in VMware ESXi 5.1, Patch Release ESXi510-201310001 (2053402). Other methods of checking per VM swap via the API, CLI or GUI are still available and are not affected by this display issue. To check per VM swapping on the ESXi console, you can use memstats. To map the VMX Cartel ID to the virtual machine's display name or .vmx path, you can use esxcli vm process list . ~ # memstats -r vm-stats -s name:b:memSize:max:swapTgt:swapped -u mb -v VIRTUAL MACHINE STATS --------------------- Start Group ID : 0 No. of levels : 12 Unit : MB Selected columns : name:b:memSize:max:swapTgt:swapped ------------------------------------------------------------- name b memSize max swapTgt swapped ------------------------------------------------------------- vm.22799 y 2048 512 451 457 vm.52303 y 1024 -1 0 0 ------------------------------------------------------------- Total 3072 451 457 ------------------------------------------------------------- Description of report header labels: name: Virtual machine name b: Is balloon driver active? memSize: Guest physical memory size max: Configured host physical memory limit for guest swapTgt: Host swap target swapped: Amount swapped by host ~ # esxcli vm process list | grep -A3 22799 VMX Cartel ID: 22799 UUID: 42 30 b6 27 ac d0 c0 63-f2 02 c9 85 73 5c 7d ad Display Name: WindowsServer2012GA Config File: /vmfs/volumes/50754a72-c3572cc0-2f5e-002522e84d6a/WindowsServer2012GA/WindowsServer2012GA.vmx
