Error is VCPU1: Guru Meditation -1149 (VERR_EM_INTERNAL_ERROR)
Hi - I'm trying to get GNS3 (Version 2.2.20) working on an Ubuntu 20.04 box with GNS3 VM (version 2.2.20) running inside Virtualbox (version 6.1.18 r142142 (Qt5.12.8)). The server has 24G RAM and I've allocated 10G to the GNS3 VM.
GS3 VM starts up ok controlled by GNS3 but as soon as I try to start a QEMU Device inside it, GNS3 VM crashes with the above error.
vbox.log and png are attached.
Thx for your attention

Thanks for reporting. This is a known, yet unsolved problem (e.g. 19824, A critical error has occurred. GNS3 and GNS3 VM).
Re: GNS3 VM on Ubuntu 20.04 Host crashed with Virtualbox error
I did find those before I posted but one is based on a Windows 10 host rather than my Ubuntu 20.04 host, and the other is a different error or doesn't that matter?
Thx

VERR_EM_INTERNAL_ERROR and VINF_EM_TRIPLE_FAULT are both triggered when the VMM is in an internal state from which no recovery is possible, and the internal state dumped in the log files look similar enough to me.

Fair enough - is there any indication of when this may be fixed, please? We have some training requirements for this box and it's not usable as is.
Thanks
Thanks

The developers never release timelines or roadmaps. So if you have a time-sensitive requirement, it is better to not wait on Virtualbox to fix this issue. Looks like you might have to run bare-metal instead of in a VM.

Please check if your issue is solved by VirtualBox 6.1.20 and report back.

Hi
Well, Virtualbox 6.1.20 now installed and all is well. The GNS3 VM no longer takes a nose dive when a QEMU device is started. That's great news for us.
Many thanks guys

Ah spoke too soon - seems the QEMU devices that we are using inside the GNS3 VM are running like a dog (technical term for running very slowly). I've tried tweaking settings but still very very slow.
Any thoughts please gents? Or is another Virtualbox version required?

You'd need a host CPU with Intel vPro, which provides the VMCS Shadowing capability. If you're interested in the gory details, please read Nested VT-x and VMCS Shadowing.
