Old Linux on Virtual Box 5.2.4 gets Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT)

[Dave Rivers]

Migrating a running (older) Linux guest from Mac OS hosted VirtualBox 5.2.3 to FreeBSD hosted VirtualBox 5.2.4.

Exported all the machines as an appliance from 5.2.3 and imported them to the 5.2.4.

All virtual machines operate correctly except a rather ancient Linux that fails to boot with a VCPU0: Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT)

I will attach the log files.

I should add, the very same virtual machine was running fine under VirtualBox 5.2.3 on the Mac OS host; it was simply exported and imported to VirtualBox 5.2.4.

However, the host CPU did change...

Some more info on this - sometimes the virtual machine simply crashes without entering the Guru; with this assertion found in VBox.log (slightly edited to fit into the WikiFormat box):

And - I have also demonstrated this problem on the RedHat Linux 6.2 installation CD; i have an ISO image of that if someone would like to reproduce this for themselves.

Simply create a new machine with a small hard disk, etc... and boot the ISO image; it will start up the LILO boot, but when the Linux kernel begins this assertion is triggered and the virtual machine aborts.
