Hello everyone!
I try to run virtual box inside VM, but when I run vm inside virtual box it freezes.
How it looks:
https://gyazo.com/d837355d90eef7f8715b5a8914c61712
I still see virtual box start screen, F12 button not working.
But I can reset /poweroff this VM and virtualbox GIU working, I dont understand what hapening.
I check my PVE, nested virtualization enabled, my CPU support it, inside guest VM (centos 7, where installed Virtual box ) I run:
Code:
Select all

and see virtualisation is activated.
I check another VM with same qemu settings, with windows guest and Hyper V in it. Everything is working I can run 64bit VM, also I try VMware ESXI, it also works. I dont understand why Virtual box not run VM.
My proxmox VM config:
Code:

Also I try to run vm via terminal command, no errors in output:
Code:
Select all
[root@localhost ~]# VBoxManage startvm 4
Waiting for VM "4" to power on...
VM "4" has been successfully started.
I try to Enable/Disable CPU acceleration, PAE, Nested Paging, add vCPU/RAM - nothing helps.
Please help me run Virtual box correctly =)
I need it for internal testing (vbox + vagrant tests)
Sorry I can not post links =(
Please attach the images locally in your response (see the "Upload attachment" tab below the reply form). Not a lot of people will go to 3rd party sites. Plus, it's more convenient if the image goes along with the message, same with the log. Oh, and you should
ZIP
your logs. It helps you, it helps us, it helps the server, it helps save a (virtual) tree or two...
Nested virtualisation problem (Virtual box inside KVM)
For the moment the only supported configuration is VirtualBox inside VirtualBox, nothing else. I'm afraid I'm going to have to mark this as [NotSupported].
I understand this is unsupported configuration, I just think maybe some one have same issue and solve it =)
Or you can tell some VitualBox tweaks or troubleshoot guide.

If I knew anything I would have already told you in my previous answer.
I just got VirtualBox-on-VirtualBox myself working. How about trying yourself that too first?
