VMWare workstation freezing on the host.


I am having an issue with VMWare workstation 15.0.2 (build-10952284)

What happens is when I run guests sometimes the host freezes for 45 minutes - cant use the mouse or anything.

However the host machine can be pinged - so at some level it is responding.

After this time it comes back to life as if nothing happend after about 45 minutes.

My host is running the latest version of Windows 10 Pro and it has 64 GB of Ram.

I have checked that I am running the latest Windows 10 upadtes. BTW the freeze only happens when I am
running VMWare with guests running. If VMWare is not running then I have no machine issues.

Any suggestions on how to resolve.

when the issue occurs, immediately open Task Manager or better Resource Monitor to check CPU usage of all processors and processes, to determine if the VMWare related resources are occupying most of the processor time as well as computer memory.

please let us know how it goes. thanks.

Hi bbao.

Sorry I am not able to do that. I should of made my question a bit clearer. Even the mouse is frozen nothing responds. The mouse pointer is frozen. Ctrl-alt-delete does not work.

I have that running here and on my home machine no issue.

Uninstall VMware Workstation completely.


If your guests are 64-bit guests, make sure the BIOS VT-d virtualization setting has been enabled.

Download VMware Workstation again to make sure you have a good copy.

Install and test.

and what you don't mention IS HIGH LARGE ARE THE VMs!!!

does this host have SSD ?

Hi Andrew / John,

I have done the install and uninstall.

Thanks for your replies.

Good point did not think of that :)

Ok here the details of my hardware. Plus the size of the VM I am running below.


Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz, 3501 Mhz, 6 Core(s), 12 Logical Processor(s)

Video Card:


GA-X99-UD4 (rev. 1.0) rev. 1.1

Raid Card:

Adaptec RAID 7805
The PMC Adaptec 7805 SAS/SATA 6Gb/s PCIe Gen3 RAID
Raid 6 running on four Sata HDD.

Virtual Machine:

Windows Server 2008 R2 x64
Memory: 8 GB
Processors 2
Hard Disk (SCSI): 100 GB <- Split disk into multiple parts
CD/DVD: Auto detect
Network Adapter: NAT
USB Controller: Present
Sound Card: Auto detect
Printer: Present
Display: Auto detect

My virtual machine runs on this RAID card. So in general the I/O is not spectacular - which is what I expect. But most
of the time it does not freeze. More like it does it enough that it is frustrating and of course I cant predict when it is going to happen.

Maybe on the Host machine, update BIOS, Chipset and Video drivers to see if video is partly responsible

this does not help performance. why split?

A single 100GB disk performs faster than split.

Seems quite a low spec VM.

Do you have reserved memory for this in VMware Workstation options ?

e.g. reserved memory for 16GB ?

Hi Andrew,

Thanks for the response. Actually I must admit I just went with the defaults for creating the VMS. So did not think to put it in one file. Would rather save the space a bit.

I guess the performance does not worry me too much in general - but only the fact that it can freeze.

I have attached a screen shot of my reserved memory.

Reduce to 16GB

and select Fit all in RAM.
whorsfallAuthor Commented:

Thanks for that. Can you explain your reasoning a bit please so I can understand.


Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
1. Your VM is only 8GB.
2. You only have a single VM.
3. Therefore WHY allocate and reserve ALL (87%) your System Memory for VMware Workstation. Does not leave much for the Host!
4. Swapping virtual memory writes to OS disk.

I would try that and see if it's better.

If you want to allocate that much to VMware Workstation, you might as well use ESXi.
