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

[tom]

can you start/create KVM guest on the commandline?

 

[Wayn0]

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

any hint in

# dmesg

 

[tom]

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).

 

[Wayn0]

Just done the bios update.

Sorted! :-D

Thanks

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...

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

 

[Behnoosh Nushi]

I have the same problem. CU does not support KVM. How can I use OpenVZ instead? Can you help me with that plz? I am new to that . thanks
