I am having an issue where when I power on a client, one of 3 things will happen :
1) Client starts normally
2) I get a VMware initializing screen, that will stay forever. All options to this client will be greyed out, this is the most common.
3) Black Screen, I can't see what is going on, but inputs are available, rare
In 2) & 3), if I try to close the VMWare workstation window from taskbar, I get a "Virtual Machine is busy" message
If I kill the VM workstation from task manager, it will be killed and when I restart the VM workstation, I will see that client already powered on and running normal.
There is no time from the kill to restart of VM workstation for the client to have reached that stage of startup,
so the only conclusion is that the client runs fine when I initially power on, but the workstation GUI failed to connect to it properly.
Once the VM workstation GUI connects to the VM clients, it works fine even I reboot the client multiple times.
Host OS is responsive throughout.
Any idea what might be causing the issue ?
My host is Windows 10 Pro 1703, with 24GB ram.
VM Workstation Pro version is 12.5.6 build 5528349
Clients include windows 7 SP1, 10 1703, Server 2012 R2 and CentOS 7
