[Solved] Guru meditation

[Linux_on_win10]

Hello,

Searches say it is a memory related issue. However, changing RAM allocation does not help.
The log says Guru meditation kicks after a patmR3HandleDirtyInstr line

Thank you.

Partial logs are not any help I'm afraid. We will need to see the full VBox.log file from the guest in question. zip the log file and post it.

Thank you.

Attached files:
File 1 is the log from the last run.
File 2 is the whole log from the opening post


Edit: The last log does not mention Guru meditation although Vbox threw one!

VirtualBox VM 5.1.26 r117224 win.amd64 (Jul 27 2017 12:32:13) release log

VirtualBox 5.1.26 is very old (almost at it's 2nd birthday). I would recommend upgrading to the latest 5.2.30 or 6.0.8 version.

You need to enable this in the motherboard / PC / laptop BIOS. Your Intel Pentium N3710 CPU supports it. See your PC's manufacturer help on how to do this. Also, make sure that nothing else has an exclusive hold on the VT-x.

Thank You. Enabling VT-x did the trick.
