Constant crashes on booting

[Blox]

What can I say....
The virtual machine fails to power up.
I've reboot the host several times but no luck.

I've enclosed a log file and screen shot.

Thanks in advance

Low memory error...

I'm using PrimoCache to speed up diskacces. Configured something wrong and it ate all my RAM
I fixed it and things got better but still unstable.
I now removed PrimoCache and all works fine.

Is there a known incompatiblity with disk caching software?

I haven't heard of such software mentioned on the forum. Anything besides the host OS itself involving itself in RAM may get in the way.

Do you have any host benchmarks showing that this software makes your host PC substantially faster?

Frankly, it sounds like Primo snake oil. Totally not necessary on a modern PC.

And of course instability is to be expected when you allocate 11GB on a PC that only has 7.5GB left.

I'm not at home now. I'll run some benchmarks on Monday.
I can say it doesn't make a diffrence for large file transfers, but it seems to do for 4K blocks.
You can test it 30 days for free.

That was a configuration error. Starting from my second post I had >32GB free.
But there's a big difference between the crashes.
With low memory the VirtualBox didn't even load (obviously)
With lots of memory it's instable.
With PrimoCache removed no crashes sofar.

I used to run the another welknown virtual solution (being cryptic because I don't know it's against forum policy to mention it). Never had crash with it.
In fact craches have been extremely rare for years in general.

You must know two things, English isn't my first language so I may come across a bit blunt at some times.
For years I used a AMD x370 motherboard. Last week I upgraded to a x470 motherboard. Also a new CPU. Rest of the hardware is the same.
I'm telling you this because the curlpit may be a incompatibilty issue between my new hardware and PrimoCache, VirtulBox, something else, or a combination.
So that's why I asked it's a know thing. But from the answers I understand the answer is "totally unknown"

Nope, we mention VMWare all the time. The only prohibition we have is against selling it here or having a support thread here. Note however that VMWare and VirtualBox don't share any code, so comparisons between them such as you drew are relatively meaningless.
