..
does that mean virtualbox emulates or simulates(dont know the difference between emulate and simulate) a 32 bit processor??
also i want to know whether it will work on my laptop.. i got intel core 2 duo t6400.

thanks in advance

Hi your hardware is 32bit but you have 64bit operating system, we cant install 64bit os in 32bit hardware but we can install 32bit and 64bit os in 64bit compatible hardware

i have read from the given thread that if flag contains lm then it said to be 64 bit

That is an even more certain way to know your CPU is 64

That line tells you it is 64 bit. Notice the lm (meaning "long mode") that I highlighted.

That line also tells you your cpu is 64 bit.

All 32 bit x86 cpu's have 32 bit virtual addressing. All current x86-64 cpus have 48 bit virtual addressing. Future 64 bit cpus are expected to have more than 48 bit addressing.

The physical address size is more varied by CPU model. A 32 bit cpu could have 36 bit physical addresses. Apparently a 64 bit cpu also can have 36 bit physical addresses (I think typical 64 bit cpus have 38 or more bits physical address).

Did you select "Fedora 64 bit" in Operating System type? You can't install with "Fedora".

Just in case you didn't know, Fedora 14 is the latest version. Version 11 is probably way out of date.
