fail to boot with VT-x/AMD-V in 1.6

Hi,

I have an INTEL Core 2 DUO T9300 and using Mandriva 2008.0.

When I turn on VT-x/AMD-V and start the VM, the computer just freezes and I have to shut it down by pressing the power button for 5 seconds.

with PAE/NX, I'm a bit more lucky as it simply reboots

If any of you have activated KVM in your kernel config, then turn it back off. The two are incompatible and the check for KVM's presence is broken in 1.6.0.

You are right !!

I had the kvm and kvm_intel modules loaded. I removed them and now, my VM starts correctly with the VT-x/AMD-V option

Thanks a lot.

I have Ubuntu 7.10 Gutsy amd64, the VT-x/AMD-V does not work here on my AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ with no kvm module loaded.

no kvm modules loaded here and still have freezing of the virtualbox window. The way I get out of it is selecting to power off the machine from the menu at the top of the window. So the software virtualbox is not freezing just the machine running inside it. In case that helps defining symptoms.

I've fixed the AMD-V problem with VMs just sitting there with a black screen. The update can be found in SVN or wait a bit for the next release (due out very soon).

Good news !
What is "very soon" like ?
Will all the versions be released at the same time ?

I have the same issue with Virtualbox 1.6.0 in 32bit XP. Trying to run Fedora 9 in a VM with the AMD-V enabled and it does not boot. Solid black screen.

Same here:
AMD X2 6000+ Processor
2gb ram
opensuse 10.3 32bit with Vbox 1.6.0. (from Repos)
I get black screen with any VM Guest that I try (all guests are 32-bit)

How can we check? opensuse 10.3 running kernel-default 2.6.22.17-0.1

Confirming fixed with 1.6.2 running under Ubuntu Hardy host and various VB clients.

1.6.2 is working well for me also. Seems a bit snappier as well.
