Known Issues

• Virtual machines running Linux kernel version 4.7 or above may crash or hang on hosts with Intel CPUs

  Virtual Machines running Linux kernel version 4.7 or above may crash during installation or during power-on with a crash in the intel_powerclamp driver. This issue has been reported with Ubuntu 16.10, but it is a generic Linux kernel issue.

  Workaround: VMware is working with the OS vendors to have them fix their respective kernels. Until a fix is available, you can blacklist the intel_powerclamp driver so that the buggy code doesn't get loaded.

  To blacklist the driver:

  Add the kernel command-line option modprobe.blacklist=intel_powerclamp to the guest OS's default grub configuration or add it directly at the grub menu during boot.

• Some driver files are not deleted after uninstalling VMware Workstation Player from a Windows host operating system

  After VMware Workstation Player is uninstalled, the following driver-related files remain on the Windows host operating system:
  In C:\Windows\System32\drivers:
  hcmon.sys
vmci.sys
vmx86.sys
vmkbd.sys in case Enhanced Keyboard Driver was installed.
  

  Workaround: Navigate to C:\Windows\System32\drivers and delete hcmon.sys, vmci.sys, vmx86.sys, and vmkbd.sys.

Resolved Issues

• VMware VIX API files installed to the incorrect location

  When you install the VMware VIX API files, some files install to C:\, even when you select the default install path of C:\Program Files (x86)\VMware\VMware VIX.

  This issue is resolved.

• vmrun commands fail on RHEL 6.8 and CentOS 6.8 hosts

  Trying to execute vmrun commands on a RHEL 6.8 or CentOS 6.8 host machine, results in errors.

  This issue is resolved.

• Some driver files are not deleted after uninstalling VMware Workstation Player from a Windows host operating system

  After VMware Workstation Player is uninstalled, the following driver-related files remain on the Windows host operating system:
