[SOLVED] VirtualBox-4.3 64?

kb2tfa · 04-13-2015, 11:13 AM

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.

Code:

uname -a
Linux ron-Vostro-200 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Tnx

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?

jefro · 04-15-2015, 02:54 PM

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:

Code:

cat /proc/cpuinfo

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.

ok I'll give it a shot and post results. thank you
