Memory size issues

[nore]

Greetings to all,

I have been using my Vbox for a while with 2.8 G of memory. I tried to increase its size many times in vain / Guru meditation error / since i am using only a quarter of all my host memory /8Go/

Is there anyway to use more memory please, I would like to allocate half of my Host memory to the VB if possible ?

The other problem I am ecountring is that when I run some simulations on my linux VB it takes too much time, the same simulations are extremely fast on a machine with linux dualboot. Is there a way to improve the performance on the VB please?

Thank you in advance for your attention and answers.

Best regards,

Nore

We can't answer that question with the information given. We need to know how much memory is actually available on your host; knowing how much is installed tells us nothing really.

Also, if your host RAM is fragmented then this can make it difficult to allocate one big contiguous chunk for a VM.

Thank you for you answer. In fact, I mentioned in my previous post that the host memory is 8 Go.

I will check the fragmentation issue and let you know later. If it is, is there any chance to overcome this problem?

Thank you again.

Thank you for you answer. In fact, I mentioned in my previous post that the host memory is 8 Go.

I suggest that you read my previous reply a little more carefully.

Sorry, the available ram is 5.5 Go.
As for fragmentation I do not think so, I don t know where to check that. Could you tell me where i can check that please? Sorry if it sounds evident but I don t know how.

I think I'll need to see the log file for a failed session. Post it as a .zip attachment please.

I don't of a way to detect memory fragmentation, except that if you try to allocate a large amount of memory in one chunk, and it fails, then that may be the reason. The only cure would be to try a smaller chunk or add more RAM to the host.
