Hi, I am having an issue when I try to launch Rancher Desktop. I am running Ubuntu version 18.04.6 LTS. I have a suspicion the error is because I need a newer Ubuntu version but I am not sure. Also, my CPU has virtualization enabled (checked BIOS) so I am not sure why it is doing this.

Error: virtualization does not appear to be supported on your machine

It's hard to say what's causing that problem, except it's most likely coming from lima (the VM framework we use on Linux and macOS). I'm running Ubuntu 20.04.4 LTS with no problem, and would recommend upgrading.

I just did a Google search on your exact error message:

"virtualization does not appear to be supported on your machine"

, and your question on Stackoverflow is the only hit, so I'm wondering where the message comes from

I think its not useable with VM, so I installed it on windows. But now I am getting a new issue

Just to be sure, do you have the necessary permissions on

/dev/kvm

(when running on Ubuntu 18.04? IIRC some users had problems like this on Ubuntu 18.04. For more info see https://docs.rancherdesktop.io/getting-started/installation#ensuring-you-have-access-to-devkvm

Yeah, I did the

[ -r /dev/kvm ] && [ -w /dev/kvm ] || echo 'insufficient privileges'

command in cmd line

What is the result of

ls -l /dev/kvm

?

Nope. I was rebooting

Sorry, all of this pertains to your ubuntu installation

So on ubuntu, running

ls -l /dev/kvm

ls: cannot access '/dev/kvm': no such file or directory

Sounds like there is an issue with loading the kernel module. We're getting to the limits of my knowledge here. A couple things you could try: • run `sudo dmesg | grep kvm`; do you see any output? On my machine I have this line:

[   11.869780] kvm: Nested Virtualization enabled

• try running

find /lib/modules -name '*kvm*'

; is your output similar to the below? If not, you might need to install kernel modules to get KVM working

/lib/modules/5.16.19-76051619-generic/kernel/arch/x86/kvm
/lib/modules/5.16.19-76051619-generic/kernel/arch/x86/kvm/kvm-intel.ko

sudo dmesg | grep kvm

Running this in cmd, nothing happens

Yeah so you don't have the KVM kernel module loaded

Running

find /lib/modules -name '*kvm*'

Displays:

Seems like you have the needed modules there. Try loading the KVM kernel module?

What would be the command?

Not sure... it would be something like

modprobe kvm

, but check that before you do it

modprobe kvm not it seems

That looks like a good thing to try. The problem is definitely somewhere between the BIOS and the KVM kernel module. There has to be a reason why /dev/kvm isn't there

So it seems

That's interesting. And yet you enabled it in the BIOS

Yea, it is enabled in the BIOS

I suspect your BIOS. I don't know what WSL error code 4294967295 is, but for it to not work in a similar fashion on two different OS's seems to point to that

I will look again
