Brand new install of 11.10 64-bit Ubuntu. While getting my conky script up and running I kept seeing the error Conky: attempting to use more CPUs than you have! and that was weird because Ive never seen that before with other distros on the same box which is definitely a dual-core CPU.

Doing some investigating it seems that Ubuntu is only recognizing 1 core on the CPU. I do have ACPI enabled in my BIOS. Im not sure if it matters but this is a guest VM installed in VirtualBox on a Windows7 64-bit host.

Here is the output of: lshw -class cpu

It sounds like your VM has been configured to provide a single virtual core given that dmesg output.

The following documentation might help you in reconfiguring your VM to provide multiple cores:
