Freezing VB

Postby momceras » 1. Aug 2019, 19:20

Hi,
Sory for my english, but I will try to explain my problem.

VB started to hang after start any guest (even new ones).
My guest's are windows, ubuntu and debian, so it should be a host side problem.

Since the hosts are hanging, I can´t give a real clean log from the machine. I have to kill VB to get access again.
There is one sample with a windows 7 guest machine.

Steps to try to fix:
-Unintalled and reinstalled VB
-Installed an upgraded VB after Uninstalled
-Create a new VB guest


Any hint would be preciated

The last line of the posted log is:
00:00:10.621612 VMMDev: Guest Log: BIOS: Booting from Hard Disk...


Do all of the guest logs end like this?

This is also in the log:
00:00:05.714728 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:05.979968 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...


This is a sign that you may see the green turtle icon Image in the guest task bar, instead of the normal blue square V Image, indicating that your guest is booting but is going to be mind-numbingly slow doing it.

This slowness is due to Hyper-V hogging the VT-x capabilities of the host. See I have a 64bit host, but can't install 64bit guests Carefully go through each command in the 2nd & 3rd posts.

I'm attaching another VM. This time is a live cd based on a 32 bits setup. Same problem occurs.

It seems is't fixed by removing VirtualMachinePlatform
I have used
Disable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform
using powershell

Still the same problem:
00:00:26.438170 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:26.465790 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...


What made you settle on just that one powershell command? Interestingly it is not mentioned in the tutorial linked above, which has always fixed this problem for those who actually follow the tutorial....

"Virtual Machine Platform" is one of the things to check for. Now... how do you remove it? There are many ways to skin a cat, a specific PowerShell command can be one of them.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

How true! (You should have seen the look I got from a guy when I said that to him once. Like I was about to start an animal sacrifice or something... :shock: )

I had gotten the impression that OP hadn't actually read the 64-bit tutorial, but yes I see now the "Virtual Machine Platform" in the list of things to check off.
