*2 To change the thresholds of disk free space and disk usage rate, modify the registry:
Key: HKEY_LOCAL_MACHINE\SOFTWARE\NEC\PVM\Provider\VM\HyperV\
▪ Disk free space
Value (Type): FreeSpaceThreshold (REG_DWORD)
Default Value: 2048 (MB)

*3 Virtual machines go into the Paused-Critical state if the free space of CSV falls below
200MB. CSV[Critical] event is notified when a virtual machine is in the Paused-Critical
state.
CSV[NonCritical] event is notified when the capacity monitoring detects the free space
of CSV exceeds 200MB, which does not automatically recover virtual machines from its
Paused-Critical state. Those virtual machines need to be manually started after verifying
that there is sufficient free space.
