Workstation 12 + AVG = lag in VM
« on: December 13, 2016, 07:43:57 PM »
Hi!

I had this issue with Avast newest beta and today I decided to give AVG a try. However, the issue is the same:
With AVG installed on HOST PC, my VMware 12.5.2 build-4638234 virtual Windows 8.1 x64 is stuttering everywhere. Host Windows 8.1 itself is fine.

Does not matter if I open a program or simple Explorer on VM W8.1, still there's noticeable stutter in the process.
See video example: https://dl.dropboxusercontent.com/u/19324974/2016-12-13_20-39-17.mp4
Disabling AVG on HOST does not help - still having this lag. Almost looks like FPS is capped.

Uninstalling AVG/Avast beta solves the issue for me + I do not experience it with latest Avast stable release. So it's definitely the beta software that is causing this.

If it matters, I have Glasswall + Zemana AntiLogger latest versions on Host machine. i5-750, 12GB RAM (VM has 2 cores and 2GB RAM).

EDITED.
HOST = My PC/actual Windows.
VM = Virtual machine set up in VMware.

I was testing AVG in VMWare today and it worked fine. Though I have 4x 4.5GHz cores and 4GB of RAM dedicated to VM machine running on Samsung 850 Pro SSD so maybe that's not exactly a benchmark. Oh and I was running Windows 10 instead of 8.1.

I'm sorry if I did not express myself clearly ;)

I have lag problem when Avg or Avast beta is installed in Host. In VM both run fine.

Host: AVG or Avast BETA =
VM: lags

2Gb ram is not enough to run a OS in a VM decently, unless you run Windows 95,98, XP.

I know. I will reconfigure it. But this is unrelated to the problem. It's not the Ram that is causing the lag. Avg and Avast are. I've done reinstall of both but without luck. As soon as I change to some other AV on host pc, everything is OK in the VM.

Hi, nested virtualization is implemented in this build. We should enable nested virtualization only for fast enough CPUs in future releases. For now, please disable virtualization in troubleshooting settings and reboot.

Sorry for that, it's a GUI bug  :-[. It should be present there. Please use notepad.exe to add following line into [Common] section of c:\ProgramData\AVAST Software\Avast\avast5.ini (settings.ini in case of AVG)
VirtualizationMechanisms=0

Then reboot.

It is in the above instructions the bracketed text relates to the AVG beta (settings.ini in case of AVG), the remainder is for avast.

Sorry, but I did not understand.
C:\ProgramData\AVAST Software\Avast

avast5.ini does not contain anything related to "virtualization".

The VirtualizationMechanisms key is not present in file, you have to add it under [Common]

Thank you! Seems like it fixed the stuttering :)!

Do I loose some protection by disabling it?

Virtualization is used by CyberCapture, SelfProtection, Antirootkit; so yes, there is some impact
