Hello all, I have ubuntu 9.10 64-bit on a Acer Aspire 4530, and if I enable AMD-V in VirtualBox and run it it completely freezes the system and I have to do a cold restart. It works fine if I turn it off. I have done some research, and tried adding nohz=off to the end of my kernel list in menu.lst, and it still freezes. Please help!

Hi! I am having the same problem on an Acer aspire 5517! Is there any way to run a 64 bit guest system or should I just run it 32 and use the software virtualization?

On my install Ubuntu freezes if I enable software virtualization regardless of whether the guest is 32-bit or 64-bit. The weird thing though is it only does it with certain guests. For example, Vista freezes it, but Windows server 2008 R2 Standard does not. Also I am running the latest version and it still does it.

This is no longer Virtualbox, but also with VmWare. It seems no matter wha it freezes.

Did you find a solution for virtualbox?

It seems I have the same problem, every 10 seconds or so, the guest freezes and then gets back to normal. Impossible to work like that...

I am having the same problem with vmware :(

Nope, I have yet to find a solution. Hope it will be fixed in Lucid, or a new version of Virtualbox.

Currently running 2.6.31-20 going to upgrade to 2.6.31-21, would custom compiling 2.6.33.1 fix it?

I had a PAE kernel in the host, and had a lot of problems. I changed the PAE by the generic kernel and all my problems were gone.

Why don't you then try the PAE kernel? It might work for you...

Ok, I'll let you know whether it works.
