Hello,

Im running Virtualbox 5.2.24 on Windows 7.
My Guest OS Windows 10 1809 freezes and virtuallbox exits when playing a youtube or any video in Chrome after 1/2 minutes.
I tried to install a 32bit version of Chrome but same problem happens.

It also occurs when i try this guest os on Ubuntu 18.04 same VB version.

On 5.2.24 there where no problems, i tried both extension packs - 5.2.2.22 and 5.2.24.

Logs are attached, thanks.
Kind regards Shaffy

You have assigned all of the physical cores of your CPU (the thing VirtualBox cares about) to the guest. This may lead to resource starvation on the host as ultimately, VirtualBox is an application running on the host. I would reduce the CPU count to 2 or 3.

I'm not sure what causes this but it probably warrants some further investigation as to your host.

Have you tried VirtualBox 6.0.2 (current as I type) to see if that is the same?

Hello Andy,

Thanks for replying!

I always assign 4 cores to my VB Images, it never caused any problem for doing my taskś on both Guest as Host machine.
Stuff like this is also reported in the logs created by my second Windows 10 1809 Enterprise image which runs fine without any crashes.
Both machines are identical in setup for software ect, except the other is LTSC.

I tried on Host Ubuntu 18.04 with Virtualbox 6.0.2 (Guest Windows 10 1809 Enterprise LTSC) but know after 5 seconds of a video play VB exits without any error/warning box..

Logs attached.
Kind regards Shaffy

I did disable Audio on the machine settings and video know keep playing in Chrome.

VB5.2.2.26 came out, same problem..
However i tried a few things which did result in no crash when playing/streaming videoś thru a browser:

Uncheck the audio box in machine settings, result in no audio at all

Check audio but uncheck audio output to host.

And instead of using Intels HD Audio choosing ICH AC97 from the dropdownbox.
A unknown audio device pops up from the devices menu with no driver.

Seems that 6305_vista_win7_pg537.zip does the job, and after a reboot sound is working and no crashes.

Why Intels HD Audio gives no problems on my other almost identical W10 versions seems to be a mystery, only LTSC does not play nice after the latest updates.

Kind regards Shaffy

hey folks, I had the same issue and as @shaffy89 said, the solution is to use 6305_vista_win7_pg537.zip. No crashes in my case too!
