If you don't have VMware Tools installed, you can still set the clock's option for internet time to sync with some NTP server. If you use an NTP client in the VM, VMware recommends disabling periodic clock synchronization, but not disabling VMware Tools altogether. If you have VMware Tools installed, then the taskbar's notification area (near the clock) has an icon for VMware Tools. If your time resolution requirements are greater than what the VMware Tools can provide, consider installing an NTP client into each VM. That resolution might not be enough for some computing requirements. That interval can be modified by adjusting the value in the VM's. inner working of QEMU and its interaction with KVM. When Erlang was designed, it was assumed that the wall clock time in the system showed a. mechanism to manipulate the virtual machine clock and hide the real I/O completion time. It only verifies its time against the local OS, and only once per minute by default. The runtime system works towards aligning the two system times. Without slew mode, this time difference will be stepped within 15 minutes. The VMware Tools' time resolution is fairly coarse. When migrating VMs, the VM is paused, not restarted, so there can be a time difference of several seconds or more when the VM resumes. VMX file to turn on this periodic tune up. Alternatively, you can set the tools.syncTime=true configuration file option in the VM's. Disable and enable the Time Synchronization option in the virtual machine settings (via the Hyper-V Manager console). Power off and power on the virtual machine. You can turn on periodic synchronization from within the VMware Tools control panel inside the guest OS. However, below are a few workarounds that you may try to sync the time: Pause and resume the virtual machine. You must have the VMware Tools installed into a guest OS to use its time synchronization service. Typically, you can synchronize time between VMware VMs and the real world either using the VMware Tools built-in synchronization service or through some kind of NTP client. If you are running VMware desktop virtualization products on a multiprocessor system in which the timestamp counters (TSCs) do not remain synchronized between all processors, the operating system clock in each virtual machine can perform unpredictably. VMs that don't receive attention from their hypervisor will eventually have their time skewed unless there's a mechanism in place to fix it. You should already know that time in VMs gets skewed because of virtualization effects.
