I have an virtualized ubuntu server 16.04.4 instance (from osboxes.org
) that I run with virtual box.
It runs smoothly with a single core, but as soon as I add another cpu it won't start up: The exact point when the system freezes (like shown in the screenshot above) changes from one start to another.
I tried different numbers of cpus. IO-APIC is active as found on other sources. Nothing changed here. Thanks for your help
Update
- I'm running this on my laptop, HyperV is enabled.
- Processor is Intel i7-4700MQ (4 cores, 8 threads)
I have 16gb of ddr3 ram
I have installed the current stable version of Virtual Box, 5.2.8
