I've been having random VirtualBox 6.1 crashes, which I'd assumed were due to lack of ram / ram issues.
I've now upgraded to more ram and I'm still seeing them, so investigated the latest Guru Meditation and I'm seeing this error:
00:44:26.495323 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
00:44:26.495324 !!
00:44:26.495325 !! VCPU0: Guru Meditation -5300 (VERR_IEM_INSTR_NOT_IMPLEMENTED)
00:44:26.496473 !!
Google doesn't seem to provide any further information, any suggestions what I can do or if there is something I can tweak to work around this. Having my VM stop working at random is a pita! I've attached the full log too.
I'm running windows 10 64 bit host, and Ubuntu 20.04.2 LTS 64-bit guest
Thank you.

Re: VirtualBox 6.1 Guru Meditation error (VERR_IEM_INSTR_NOT_IMPLEMENTED)
Try disabling Hyper-v.
I would also reduce CPU cores to 2. More cores never necessarily makes any PC faster, but in the case of a VM unused cores will definitely make it slower.
See FAQ: HMR3Init: Attempting fall back to NEM (Hyper-V is active)00:00:03.529890 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:03.552818 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

Thank you!
I actually do code development in my VM which is heavily multi-threaded, so more CPU cores does help me quite a bit.
I've removed hyper-v following the instructions you linked (I thought I already had, I experimented with WSL2 to replace the VM a month or so back but it wasn't good enough performance wise).
Time will tell if this helps, it used to blow up every 2-3 days so I should know by early next week.
