Nested Virtualization with Virtualization Station on TS-x51+

[cnemcse]

Upon searching for this, I've seen this asked a number of times, but not effectively or concisely answered, so here goes:

The following instructions were tested successfully on a QNAP TS-451+ with QTS 4.2.3

It *IS* possible to get nested virtualization working!

First, stop all running VM's and close out of Virtualization Station
Log in to shell as 'admin' using an SSH utility like Putty
Edit the file /KVM/modules/Insmod.sh with vim

search for all instances of kvm-intel.ko and append the following parameters: nested=y ept=y
i.e. /sbin/insmod ${KERNEL_MODULES}/kvm-intel.ko nested=y ept=y

save and exit vim

power off and reboot the QNAP

Once the system reloads, all VM's will have access to VT-x hardware virtualization, so for example, you could run ESXi or Ovirt as a guest.

I have a Qnap TVS-473 but the directory /KVM/modules doesn't exist.
/sbin does not sure which directory or file i have to edit in their to do this.

[ddbyam]

I found the directory
/sys/module/kvm
/sys/module/kvm_amd

But no insmod.sh in any of those directories

[ddbyam]

I think I figured it out.
The file that needs to be edited in /lib/modules/kvm and lvm_amd
The issue is that qnap is using x86 instead of x64 arch
It does support nested vm's just x86.
I hope they work on getting x64 nested vm's working.
Would be nice to us vs3 as a VM lab

Sorry, I can't speak to other models. On my TS-451+ the file paths mentioned above in my original post are correct, and x64 nested virtualization is supported...

BTW, /KVM only exists *AFTER* you install 'Virtualization Station"

Hi,

Nested on QNAP , it doesn't run !
See my post below :

Are you now able to use nexted virtualization after upgrading to QTS 4.3.x with virtualization station V 3.0 ?

[pungpond]

First, stop all running VM's and close out of Virtualization Station
Log in to shell as 'admin' using an SSH utility like Putty
Edit the file /KVM/modules/Insmod.sh with vim

search for all instances of kvm-intel.ko and append the following parameters: nested=y ept=y
i.e. /sbin/insmod ${KERNEL_MODULES}/kvm-intel.ko nested=y ept=y

save and exit vim

power off and reboot the QNAP

It work !!!!
thank you very much .
PS. I cannot see the file Insmod.sh so I modify Insmod_ko.sh instead.

TS-451+

Sorry for a dumb question...

Is this for Linux hypervisor only or can hyper-v or VMware hyporvisors run nested? I am trying to get 1. ESXi running on V.S and also 2. Hyper-v to host some VMs. I am trying to do some testing of both in QNAP V.S lab.

Blimey, how slow's that going to be, hypervisor in hypervisor! Good luck there.

yeah.. that will be "blazingly" fast on a x51+ processor ... ouch.

I'm sorry to bring up a similar thing again and first of all, thanks for going out there and finding all this stuff out for us all. My end goal is to run an instance of eve-ng.

I'm on a TS-451+ on 4.3.3.0262 Build 27th July, I have Virt Stn installed and have a couple of VM's on there and they run OK. I'm intrigued to taking advantage of VT-x on my NAS as an added feature on top of all the other crazy stuff it does for me already. I realise my firmware version is newer than the original poster and appreciate the differences that can some about.

So, after looking from the start of the thread, as well as some other threads, I'm struggling to even put several of these instructions together, so would like to seek some advice.

So, I'm getting stuck at the first hurdle, where is /KVM and I wonder if that's what I'm even looking for?

As I've just picked up a new job with a lot more linux than what I'm used to as a home user, I'd be greatly indebted to any knowledge shown my way, please .

Hi All,

I have a TVS-682 with QTS 4.3.3.0404 and VS 3.0.2836

I have followed this guideline:
viewtopic.php?f=199&t=118544&p=650329#p627698

from "santiagax99," please refer to his entry at Sun Jul 23, 2017 9:30 pm "For VS3:"

I have installed VMware ESXI 6.5 in Virtualisation station, and have now running a 64bit Unix Image (which was not able to start before).

Many thanks
Tiscy
