Windows 10 guest freezes intermittantly

[krixkrix]

Windows 10 guest freezes intermittently, but very frequent.
9 out of 10 times during guest boot. Guest display just stops updating and I am not able to shutdown the guest properly. Not even with ACPI shutdown.
Sometimes windows gets beyond user login, but soon after I have started using the system, it freezes.
I have tried a bunch of settings, played around with everything from 3D acceleration to memory and CPU cores. All in vain.

VirtualBox 5.1.26 incl Guest additions.
Host: Ubuntu 16.04, 64 bit, 16GB RAM
Guest: Windows 10, 64 bit, 6GB RAM

I have a linux guest also which shows no or few problems.

1. Please ZIP the logs before posting them. Helps save a (virtual) tree or two...
2. Please close the VM before taking the log. If you can't, just power it off. But don't copy the VBox.log while the VM process is active.
3. Playing around with the settings at random can have one and only one effect; screw up your VM. Big time. For example:

   00:00:00.618551   ICH9 <integer> = 0x0000000000000001 (1)

   Why did you feel the need to change the chipset to something "experimental and not recommended except for OSX guests"? Please change it back to the default PIIX3.
4. This is what the partial log end with abruptly:

   That tells me that there is a potential problem with the transactions in the host. Have you run 'fsck' lately?
5. Consolidating your snapshots might help you, because in order to get to the current HD state, you have to go through 3 snapshots, which increases the I/O on the host, which might be causing delays.
6. Under VM Settings » Storage » select each of the controllers and disable the "Use Host I/O Cache". See if that changes the situation.
