1. The VM time seriously deviates from the DDC time. As a result, the VM leaves the domain and cannot be logged in.
2. The VM runs a Java virtual machine (JVM) to obtain more precise clock resolution and frequently invokes SetTimerResolution. As a result, the time of the Windows VM lags behind the standard time.
To check if a VM runs a JVM, right-click the taskbar and choose Task Manager. In Windows Task Manager, click the Processes tab and check the Description column for each process. Figure 1 shows that the VM runs a JVM.

Currently, the most commonly used JVMs are server BMC remote consoles that are accessed through browsers.
