This CPU does not support KVM virtual machines (no Intel VT / AMD-V support)

can you start/create KVM guest on the commandline?
 
Actually this is strange...

I am able to start the kvm from command line but /dev/kvm has not been created so I guess it's just running the qemu machine without kvm extenstion?
Can create and start from the command line, start and stop from the frontend but no create

Thanks

:-)

Code: 
proxmox-1:~# lsmod | grep kvm
kvm                   213288  0 
proxmox-1:~# ls /dev/kvm
ls: cannot access /dev/kvm: No such file or directory
proxmox-1:~# qm start 109
open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support
proxmox-1:~# qm start 109
VM 109 already running - start failed
proxmox-1:~#

Code: 
proxmox-1:~# qm create 100 --memory 256 --kvm yes --ide0 4 --vlan0 e1000

just to add my experience here: in 99 % of all my support cases its solved by a bios upgrade, enabling VT in the bios and by powering off the server (not just reboot).
 
I'm using 2 x Intel E5405 on Intel S5000VSA board with 8GB of memory. I have configured two VM @1 socket, 2 cores, 2GB memory and Windows 2003 Server Enterprise Edition as Guest OS. But sometimes Proxmox VE hang suddenly with CPU synchronization error.
 
I know this thread originated quite some time ago, but I am getting a similar issue also.

I install proxmox on my server (bare metal). Worked fine.

Then removed the boot disk. Added a new clean disk. Installed OS and then installed proxmox as a vm using Vmware.
Still worked just fine, except in the vm I get this msg, "This CPU does not support KVM virtual machines (no Intel VT / AMD-V support)"

Same physical machine. One was bare metal install and one was as a vm.

Any ideas?

Yup... your VM does not export the Intel-VT or AMD-V part of the CPU... I don't think that's possible in any VM system. So it'll never work like that.

Ok, thanks for the info. Then I won't spend any more time trying to make it work. At least the OpenVZ works...:D

JFI, If you are using Vmware ESX5 or workstation 8 then you can pass VTx or AMDx through to the VM that you created.


My problem is that I cant get Proxmox to do this on an Intel processor
