VirtualBox-4.3 64?
I'm confused if I have a 64 bit pc or not. I am running 64bit linux mint 17, with virtualbox-4.3
The only 32 bit options in VirtualBox. I read that there might be a bios setting keeping it from reading the processor, but I have looked inside and out in the bios. Don't see anything. Here is my lscpu.
Code:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 2
On-line CPU(s) list: 0,1
Thread(s) per core: 1
Core(s) per socket: 2
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 15
Stepping: 13
CPU MHz: 1200.000
BogoMIPS: 3591.10
L1d cache: 32K
L1i cache: 32K
L2 cache: 1024K
NUMA node0 CPU(s): 0,1

The ouput of command 'uname -a' may show it. If output shows x86_64 then it is 64 bit else 32 bit.
Also checking intel or wikipedia for you make/model of cpu would help. Get cpu info with 'cat /proc/cpuinfo' command.

Bios, cpu and chipset all need to support virtual technologies. Some bios entries are cryptic. Owners manual may help. It may not say exact enable VT-x.
However I think this is backwards from your issue. (could be that I'm backwards)
What I think is if you create a vm with a name and 64 in it the vm will create a 64 bit client.

The uname output shows that it is a 64 bit pc. If you ran uname in host then it's 64 bit or in a guest under VM then it's 64 bit .

It works fine on my linux laptop, but not on my desktop. I thought I would give it a shot to fix it, but I can work off the laptop.

I suspect that you are not creating 64 bit clients.

I am working on material for Linux+ LPIC and It would be nice if I could have a centos and ubuntu virtual clients to goof-up. I can accomplish this on my laptop. I would have liked my desktop to have the same capabilities. Not being able to recognize 64 bit doesn't hurt me so much with ubuntu, but centos 7 as we know is 64 bit only. If I could've found a fix, it would be nice, but not a deal breaker.
edit:
I think most of what I'm doing can be accomplished with centos 6.6. If I am correct, systemd is the difference with centos 7, right?

More than that.
I think you may not be understanding us. We believe you should easily be able to create 64 bit clients on a 64 bit OS host.

Yeah I'm missing something. From what I get, my processor is 64. Installing virtualbox via the repos ends in a virtualbox that allows only 32 bit option. Downloading 64 bit from their site, installs with the same results. Unless I should overlook the 32 option and try to install 64 bit?
Edit
I'll try it and report back.

UPDATE
I tried to install CentOS 7 with the 64 bit hardware and the 32 bit recognition VirtualBox. It was a no go. No errors, just wouldn't install. The best I can do on this machine is 6.6

The best way to determine architecture is to run:
Look for the "lm" in the output it should be in the flags.
If the "lm" flag is present the CPU is 64-bit.
uname-m is not reliable.
