otHello

I've installed EVE-NG (Unetlab) on unraid, when I'm logged into the console I see the warning message :neither Intel VT-x or AMD-V not found

 

I can not load ASAv

 

I've tried the command

modprobe kvm_intel nested=1

 

with no luck

 

anyone out there get this working?

I have been wanting to do this myself. I took your info to google and found:

 

https://fedoraproject.org/wiki/How_to_enable_nested_virtualization_in_KVM

 

There, I found the following, which is step #1

 

Quote

 

$ cat /sys/module/kvm_intel/parameters/nested

N

 

Should respond 'Y' if it is working and 'N' if not  available/enabled.

 

Of course if no, like mine, you next enter:

 

Quote

$ modprobe kvm_intel nested=1

 

Then you are supposed to reboot and check again.

 

So, to summarize:

 

1. Did you reboot? If not, do that.

2. After reboot, re-run the 'cat /sys/module/kvm_intel/parameters/nested'. If it is still showing N, my guess is next to check around your BIOS to make sure all is enabled.

 

I am about to test this myself here.

 

Edit: OK - that didn't work for me... After a reboot still shows:

 

$ cat /sys/module/kvm_intel/parameters/nested

N

 

 

Going to poke around the bios to make sure but I could swear I had enabled all those functions before...

Unraid is loaded into ram at boot, so whatever commands you run before you reboot will not stick. So forget about the rebooting.

Fix:

 From the article: enable it by booting with kvm-intel.nested=1 argument on the kernel command line and check it again

Modify the syslinux.cfg file to add this kernel argument.

 

1. Log in as root to your host OS (unraid) and edit syslinux.cfg.
 

     $ vi /boot/syslinux/syslinux.cfg

2. Modification is below in bold.

    default /syslinux/menu.c32                                                         
    menu title Lime Technology, Inc.                                                   
    prompt 0                                                                           
    timeout 50                                                                         
    label unRAID OS                                                                    
      menu default                                                                     
      kernel /bzimage                                                                  
      append initrd=/bzroot kvm-intel.nested=1 

 

3. Save, exit, reboot.

 

Ok thats the first part done for me, I'll come back later to finish this up (or maybe someone else can).

 

In the meantime if you have not already, make that change and reboot.

I did the command : Output from last post

 

$ cat /sys/module/kvm_intel/parameters/nested

Y

 

 

~~~~~~~~~~~~~~~

and its WORKING!!

I was able to load ASAv on my lab!

 

 

thank you slushieken

 Thanks for coming back to let me know! I have not yet had the time to actually test this at the VM level for passthrough.

 

Are there any more steps to get it going beyond that? RE: special configuration options for the VM definition?

 

It would sure help  me out, and anyone else when they come back across this if so.
