Virtual Box multiple monitor issue

Hi All, this is issue is regarding moving virtual monitors to a specific host monitor. There are 3 host and 2 vm monitors but the virtual monitors refuse to move to 1 (main) specific host monitor in Full Screen mode. it is fine in scaled mode.

I suspect because it needs enough graphics memory to run the host screen. My only suggestion would be to install a second graphics card. I would also see if the same issue happens in virthmanager, much better all round than virtual-box.

Thanks for the reply. It was working fine for a year using 2 out of 3 screens. It only became an issue after the last VB update. All 3 monitors are listed as available but "monitor 2", I cannot move a virtual screen to it.

I will try virt-manager.

A few questions for virt-manager:

  • how do you create a network bridge?
  • how do import vms?

thanks!

I don't use network bridge. The VM's effectively use a passthrough to the host machine's Network card using virtio with NAT.
It's been a while since I imported a .vhd to become a .qcow2 image. You can't import a .vdi. I only ever created .vhd's in Virtual Box.

Thanks for your quick reply. I will give it a test run. Funny, now that I look into virt-manager, vbox issue has resolved itself.

If you have two monitors with host desktop on one and VM on the other the mouse can move across from one screen to the other seamlessly. Forgot to mention you need to logout and back in again before you can run virt-manager for the first time. I had some issues recently where some VM's needed removal of NIC then adding back before VM would run. To resolve this:

sudo virsh net-autostart default

If you need a bridge:
