[Bug 1806040] Re: Nested VMX virtualization error on last Qemu versions

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  Nested VMX virtualization error on last Qemu versions

Status in QEMU:
  Incomplete

Bug description:
  Recently updated Qemu on a Sony VAIO sve14ag18m with Ubuntu Bionic
  4.15.0-38 from Git

  After launching a few VMs, noticed that i could not create Snapshot due to 
this error:
  "Nested VMX virtualization does not support live migration yet"

  I've created a new Windows 7 X64 machine with this compilation of Qemu
  and the problem persisted, so it's not because of the old machines.

  I launch Qemu with this params (I use them for malware analisys adn re...):
  qemu-system-x86_64 -monitor stdio -display none -m 4096 -smp cpus=4 
-usbdevice tablet -drive 
file=VM.img,index=0,media=disk,format=qcow2,cache=unsafe -net 
nic,macaddr="...." -net bridge,br=br0 -cpu host,-hypervisor,kvm=off -vnc 
127.0.0.1:0 -enable-kvm 

  
  Deleting the changes made on this commit solved the problem, but I dont have 
idea what is this for, so... xDD
