Enable Nested KVM - Nested Visualization

[unlandm]

Re-Installed VS -- > VS work.
Edit 01-module again. reboot . bingo

Confirm works on 4.3.4 .

Thank u

Hello wmarsch,

what did you change or insert in the 01-module file? Can't figure it out by myself...

Can you post the content of your working 01-module file here?

Thank You

This solution is working.
thank you very much.

all I have to do is adding "nested=1" at the file "01-Module"
I don't have to set VT-x in the BIOS.
at first it seems not working but after I change the CPU in VM from "i7" to "Core2" then it works.

Confirmed. "nested=1" at the file "01-Module" still works for 4.3.4.

I can confirm this works on TVS-463 (which is AMD cpu). VirtualizationStation 3 and firmware 4.3.4.0537

you just need to change this line instead:

elif [ $SVM_FEATURE -ne 0 ]; then
___load_module kvm-amd.ko nested=0

TO:

elif [ $SVM_FEATURE -ne 0 ]; then
___load_module kvm-amd.ko nested=1

Thanks to original poster

Thanks for this, has anyone managed to get Hyper-V working? I would like to enable RemoteFX for GPU accelerated VM's.

When trying to enable the Hypervisor in Windows 10 Pro I see: "Virtualisation support is disabled in the firmware"

....

I am running 4.3.4 and
I followed the VS3 instructions exactly :

For VS3:


Check KVM modules parameters after reboot

Code: Select all

 # cat /sys/module/kvm/parameters/ignore_msrs
Y

Code: Select all

# cat /sys/module/kvm_intel/parameters/{nested,ept}
Y
Y

I can confirm that I see "Y" as required after a reboot.

However in the 2016 instructions for an earlier firmware

You need to stop virtualization station from webui and ensure that kvm and kvm-intel modules are unloaded

lsmod | grep kvm

must return nothing

I do in fact still see the modules loaded:

kvm_intel 148558 6
kvm 420416 1 kvm_intel

Could this be my issue in 4.3.4 / VS3 or is it no longer relevant?

Another question - For those who installed ESXi6 - which "Guest OS" did you choose?

thanks for the help in advance.

[peelos]

I have checked and VT-x is enabled in Bios

Performed all instructions as above and see "Y" for KVM modules

>>>>

Those who say this works, what works exactly? What have you installed to confirm this works?

Has anyone got nested VM working or Hyper-V?

thanks

Hi Everyone,

I'm running a 3085u, I've followed the instructions as posted previously and am now able to boot up my 64-bit VM, however I get the follow pop up whenever I boot up my VM.

"Virtualized Intel VT-x/EPT is not supported on this platform. Continue without virtualizaed Intel VT-x/EPT?"

Am I supposed to receive this prompt? How can I verify on my QNAP that the VT-x option is enabled. Also note that on initial power up out of the box, my device was running the QES OS.

My model qnap didn't come with a built in video card so I'm not sure how I can access my BIOS to enable the option. Guidance would be appreciated.

Thank you.

Hello I used the 01-module change (kvm-intel.ko nested=1)

I get for two QNAP Systems different results.

KVM Hypervisor (Debian 9 with QEMU) is working fine on the TS-453 Pro but not on TDS-16489U.

The non working kvm is only possible if the nested mode is "0" on the TDS-16489U but it shows
# cat /sys/module/kvm_intel/parameters/{nested,ept}
Y
Y

I have no idea.

hi guys,
just want to share my experience. I have TS-453 mini (so it supports VT-x) with 8gb ram.
I have installed the eve-ng lab for networking on the Virtualization station 3 (3.1.729 (2018-09-10)). But I always got the error message when it started "warning neither intel vt-x or amd-v found"

just went with santiagax99 instructions and got all 3 checks as yes after reboot.

# cat /sys/module/kvm/parameters/ignore_msrs
Y
# cat /sys/module/kvm_intel/parameters/nested
Y
# cat /sys/module/kvm_intel/parameters/ept
Y

but still got the message.

1 more thing I needed to do is go to the QNAP Virtualization station in GUI and in the VM settings change processor type to "Passtrough" (as in attachment). then it worked for me
Haven`t seen people mentioning it here, so perhaps this will help someone

QTS 4.4.2.1270
Many thanks 5andman, this "Passtrough" CPU setting works for me with setting nested=1 in 01-module (described at viewtopic.php?f=318&t=118544#p571939 and below):

Code: Select all

/share/CACHEDEV1_DATA/.qpkg/QKVM/usr/etc/qvsd.d/44-preload/01-module
# 01-module
___load_module kvm-intel.ko nested=1
