Hi,

I tried to look for similar problem description from other people, but couldn't find anything matching. My problem is that I cannot use more than 2GB (2048MB) of memory with my Ubuntu 32b 10.04 guest running on Windows 7 64b. Everything works fine until I change the memory of guest to anything more than 2048MB (2047MB works, 2049MB or above does not).

It fails with Guru Meditation failure and the virtual box log contains the following at the end:

When I installed Ubuntu on the guest system, I had 2GB memory in use. It seems that I can at least boot the Ubuntu 10.04 installation CD with more than 2048MBs (tried with 3072MB) and run Ubuntu from there. I tried to turn on and off options like PAE/NX and VT-x/AMD-V. I also tried to change network adapter to something else than default PCnet-PCI II, because someone reported similar problem and the solution was to change network adapter (a little bit far fetched, but...).

My system:
64 bit Windows 7 host
32 bit Ubuntu 10.04
4GB of total system RAM
64MB of RAM assigned to video on guest

Running VirtualBox version 3.2.4 r62467 (guest image was created using 3.2.2)

Because Ubuntu runs fine from installation CD, this could be Ubuntu configuration related problem. However, I have no clue what should be changed in the Ubuntu config. Any ideas?

Cannot reproduce. Windows 7 / 64-bit host, Ubuntu 10.04 i386 guest, 12GB host memory, 4GB guest memory, guest boots fine. Please attach the complete VBox.log file of your VM session (use the attach function please).

Actually I can reproduce this Guru meditation if I boot with VT-x disabled.

Found and fixed the problem. Fix will be included in the upcoming 3.2.6 release.

In case you're still interested, please find the log file attached. I hope you fixed the same problem I have

Anyway, thanks for the fast reply/fix! Do you have any estimate about the publishing schedule of the next version?

Thanks but just try it out, 3.2.6 was released last Friday

Excellent, it works with the new version!
