This status shows the amount of Oracle VM or SQL Server VM memory that is currently claimed by the VMware balloon driver. It may or may not indicate a performance problem.
Definition
VM memory ballooning is not necessarily a VMware performance issue; rather it represents the host starting to distribute memory from underutilized SQL Server or Oracle VMs to those with large amounts of active memory.
Solutions
If high amounts of VM memory ballooning are occurring in Oracle or SQL Server VMs, check for high Memory Swap In/Out Rates.They may be indicative of performance problems and should be addressed immediately.
