kvm problems.

[Drone4four]

I'm using these two guides to get kvm to work:

http://ubuntu-tutorials.com/2007/07/04/setting-up-qemu-kqemu-on-ubuntu-704-feisty/

https://help.ubuntu.com/community/KVM

I get stuck here:drone4four@kubuntu:~$ sudo modprobe kvm-amd
FATAL: Error inserting kvm_amd (/lib/modules/2.6.20-16-generic/kernel/drivers/kvm/kvm-amd.ko): Operation not supportedHere is dmsg:

What exactly is my dmsg saying and what can I do to proceed with the kvm guides?

Should I try posting this thread in a different forum?

I asked a question about vmware in the Ubuntu hardware forum:
http://ubuntuforums.org/showthread.php?t=522801
It hasn't received the attention it should. I haven't got a single response there. Where should I have really posted it?

Probably here......vmware is software, not hardware. I don't know anything about it though, so I'm afraid I can't help you:(

Maybe if you request here... or in your linked thread that bohdi or another moderator kindly move it into this subforum, it will get the attention you think it should get.

Ask them to, to remove this thread if you like. Good luck with your vmware problem.

Hmm, I have installed VMware Server several times on Redhat and Mandriva. I just follow the instructions on the VMware web site. It works every time.

For VMware Player, ensure that Ubuntu is *fully* updated and happy, then use Synaptic to install it - nothing to it - clicketyclick done.

Note that you cannot have both on the same machine. In fact, you can have only ONE kind of virtualization on one machine. If you wish to change to a different virtualization solution, then you have to re-install Linux.

Hope that helps!

@ Drone4four: I merged the initial thread in here, as you had answers about it, and renamed the thread. Please check the thread title and tell me if it's OK with you :)

It looks like your hardware is not supported by kvm, probably bacause your AMD CPU doesn't support SVM.

You could try QEMU + KQEMU for the hw virtualization.

*** EDIT ***

As you can see SVM is required:

I have a similar problem.

>sudo modprobe kvm-amd
FATAL: Error inserting kvm_amd (/lib/modules/2.6.22-14-rt/kernel/drivers/kvm/kvm-amd.ko): Operation not supported

I have run
egrep '^flags.*(vmx|svm)' /proc/cpuinfo
as suggested by the kvm package. I recieved a whole bunch of flags as a response:
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8legacy 3dnowprefetch ts fid vid ttp tm stc 100mhzsteps

As far as I can tell my CPU supports SVM virtualization.
My CPU is the AMD Athlon X2 BE-2400 Brisbane 2.3GHz Socket AM2 45W Dual-Core Processor.

I thought kvm was different from VMware. Am I right?

I think my CPU supports SVM, it's just that either: (a) I haven't enabled SVM in my BIOS or (b)I haven't ompiled a kernel which includes support for SVM or (c) maybe I need to do both. My questions, therefore, are: (1) what should I look for and where in my BIOS to enable SVM, and (2) where in the kernel do I enable SVM?

Here are my CPU specifications: drone4four@ubuntu:~$ cat /proc/cpuinfo

And my AMD processor is an Opteron 175 2200 MHz 2×1024 KiB 1000 MHz 11x1.35/1.3V 110W Socket 939 OSA175DAA6CD "Denmark" (90 nm)

I am running 32bit Gutsy now. Before I was running 32 bit Fiesty.

in the kvm official documentation, this question is answered: How can I tell if I have Intel VT or AMD-V? http://kvm.qumranet.com/kvmwiki/FAQ#head-a78f5f083749cb9c2e57d7d4efaf2ecf25b9db60

The answer is input this command: egrep '^flags.*(vmx|svm)' /proc/cpuinfo The outup on my end is: drone4four@ubuntu:/usr/src/kvm-61/kernel$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo
drone4four@ubuntu:/usr/src/kvm-61/kernel$ I think this means I can't use kvm. Although, what if I changed some settings in my BIOS? Then would that command produce different results?
