Please keep the list in the loop, though! I've re-added it.

This only proves that you've installed it, not that it works.
And as I said, the modified binary probably works fine on its own but
libvirt might not be able to drive it, at least without tweaks.

Just for the record, you're not supposed to modify files in
/etc/libvirt/qemu directly; use virsh instead.

If you run
$ virt-manager --debug
from the command line you will get a lot of output, including the
XML that's passed to libvirt. Please attempt the installation again,
capture that output in a plain text file and send it to the list as
an attachment.
Also run
$ /usr/local/bin/qemu-system-x86_64 -machine help
and attach the output of that command, too.
That should help us figure out what's wrong.

[libvirt-users] Internal error reported by libvirt while creating a VM
by Ajay Kumar
Hi, am Ajay Kumar.
I am trying to create a virtual machine on the remote host (where libvirt
5.8.0) was installed using a virtual machine manager which are running on
the local ubuntu machine.
*The specification of my remote host are:*
*Hypervisor: *KVM
*QEMU version:* QEMU emulator version 2.4.0.1, Copyright (c) 2003-2008
Fabrice Bellard
The below error is propagating when I am trying to install KVM-VMI (
https://github.com/KVM-VMI/kvm-vmi/tree/kvmi) with modified QEMU, and there
is a modified QEMU involved, in /usr/local/bin/qemu-system-x86_64.
The below particular error propagating when I am trying to create a virtual
machine using VMM gui (virt-manager).
Unable to complete install: 'internal error: process exited while
