Hi experts
1. can anyone explain me memory ballooning and swap file.
What is baloon driver
2. Resource Pool- what i understand it is a container or folder consists of groups of VM. Do we reserve physical memory and CPU to resource pool?
3. can we vmotion vAPPS
forgot you other two questions, You can reserve memory and CPU for Resource pool to guarantee memory, CPU to VMs from this resource pool.
You can migrate VMs from vAPPs but not the vAPP.

Hi,
Memory Ballooning is a memory reclamation technique used when and ESXi host is running low on memory. If you have enough memory on ESXi host, you will not see ballooning happening.
Swap - In the cases where ballooning, transparent page sharing, and memory compression are not sufficient to reclaim memory, ESXi employs hypervisor swapping to reclaim memory.
Please read below document for detailed information about VMware Memory management.
Note, Guest OS memory swapping is different than Hypervisor/Vm swapping.

In resource pools do this reservation happens from physical CPU and RAM
Yes. You reserve amount of physical RAM, CPU for that particular Resource pool.
Note, you can also set RAM, CPU reservation for specific Virtual Machine.
