Getting failure to connect to VNC on my VM.

Try the following:

 

Stop the VM and go to edit mode

Apply settings without modifications

Start the VM and test VNC

Stopped the VM and removed all the modifications from syslinux config but now I get 

 

internal error: qemu unexpectedly closed the monitor: 2019-12-11T18:50:02.481030Z qemu-system-x86_64: -device vfio-pci,host=0000:09:00.0,id=hostdev0,bus=pci.1,addr=0x0: vfio 0000:09:00.0: failed to setup container for group 9: Failed to set iommu for container: Operation not permitted

 

I used the mods to get Pfsense running and it worked before the upgrade but not since.

Your description says you have an issue with VNC, it is unclear to me why you made modifications to syslinux.

 

It seems you have now a mismatch between XML settings and hardware passthru. Easiest would be to restore your syslinux as before.

 

By opening and saving the VM editor, you force the re-assignment VNC ports. I expect this to solve your VNC issue(s).

 

Thanks for the advice.

 

I will give It a try and post the outcome.

 

Good news. I can now reahc my VM's.

 

Thank you for all the help.
