Hi,

I have 8 gb ram on my machine. I am not able to buy more RAM. I need to add more than 8 GB to my guest OS. Virtualbox does not allow me to add more than 8 for guest OS.

Which is possible:

1- It is possible to add more RAM memory if I increase the swap space on my host machine?

2- I will not give 8 gb to guest. But I will run the guest OS and I will set inside VM 8 gb swap space. So this swap space will be use as RAM. But I am not usre about this...

* I am not able to buy more ram on my laptop. I need RAM for guest, even I accept that it will work slower...

* VMWare allows to give RAM more than ram plus swap space of the host machine.

Thanks in advance

You can't do it. VirtualBox need actual, physical, free, available RAM.

In fact the max amount of you can allocate to a guest will be substantially less then 8GB, since I assume the host will need a large chunk of that.

The second thing that I write, should work?! I mean I will give to guest VM 10 gb more as hard drive. And than I will set inside guest OS 10 gb swap space. And how it will not work. It will work very slow, but it should work. right?

Those are guest questions which have nothing to do with VirtualBox, or the "Linux Hosts" forum in fact. Yes, most modern OS's can swap RAM in and out to disk, whether they run in a VM or not. Yes, excessive use of paged RAM will be slower, though an SSD would help there. Without the SSD the lag can be excruciating (and perhaps even with the SSD).
