I have a virtualization question
I have a Dell Vostro 200 desktop with Fedora 22. It's a rather old machine. It's 64 bit, however the processor does not support VT. If I install VirtualBox, it will only display 32 bit options, and installs of those are hit and miss.
I have a headless centos 7 that is my sandbox to play with, is there any way of running some sort of VT on that machine, to create an Ubuntu or CentOS instance? I get no response when checking for vmx flags, but I do get this for svm Code:
[root@headlesscentos7 ron]# cat /proc/cpuinfo | grep svm If I can't do it, it's not a deal breaker, just curious. |
Virtualisation is hardware technology, so your CPU either supports it or not, I'm afraid.
|
Even if the CPU supports VT/AMD-V there's still vendors who block enabling those features in the BIOS. Sony are especially known for this sort of thing.
BTW, did you try to enable virtualization extensions in the BIOS? |
For the Desktop, I updated the bios, but after a post on this site, I found the cpu does not support VT. I'm not trying to get VT working on the desktop, that's not possible with the current hardware. What I would like to know is, can I setup any type of VT to use on my headless CentOS 7? The processor on my headless supports svm, so I'm assuming that it's VT compatible right? I see things like kvm. Would kvm be a solution? Basically I'm looking to see if I can setup virtualization on the headless centos not the desktop. I just provide the desktop info to show where I was coming from, but I now see the desktop info is really just confusing the issues. So forget I mentioned the desktop not supporting vt.

Yes, as you see by the link I posted svm is the AMD equivalent so it should allow any virtual machine software to take advantage of that including things like running a 64 bit guest OS in VirtualBox (which, I think, requires a 64 bit host OS).
AS long as you don't want any kind of hardware acceleration* (such that it is in VMs anyhow) I think, judging by this, that you can use VirtualBox headless and connect to the client GUIs using RDP. Something I really must try when I get chance. *Should have said "graphics acceleration" - other hardware may or may not provide acceleration. |
Thank you

you can definitely use kvm with a CPU that supports nx and svm. however, you need to make sure AMD-V is enabled in BIOS, the cpuinfo output shows capabilities, not whether it is enabled

I setup kvm, and it works.
