Guest CentOS Stream8 crashes when CPU# is increased

Post by Alexander_LRF »

On a recent DELL Server with i5-8500 CPU under WIndows 10 Enterprise LTSC, I tried to run CentOS 8 stream as guest under recent Virtualbox 7.04.
It is a DELL Precision 3930 Rack with 16 GB RAM.

If I allow only one CPU, the CentOS8 runs.
If I allow 4 cores, it may crash after some time
If I allow 6 CPU cores, then it crashes predictably with a Guru.

This happened before with Virtualbox 6.1.40, too.
Actually, we have 2 similar computers, DELL 3930 and on both this problems happens.
The problem does not happen with Computers with "older" i5 or i7 CPU, when using the same virtual machines.

The VBOX is 648 kB, which is above the limit, thus it is posted as zip file.

Best wishes,

Alexander

Host Hyper-V is enabled. Try 2 processors.

And even earlier: Google site:forums.virtualbox.org "VERR_NEM_IPE_3". ;)
