I have one trusty machine that is working and another that is not.
The problem seems to be in the machine name handed to qemu

qemu-systemx86_64 is passed -machine trusty on broken machine instead of -machine pc-i440fx-trusty

[Serge Hallyn (serge-hallyn)]

On the broken machine, please make sure to stop and undefine the
not-working vm, then

sudo stop libvirt-bin
sudo start libvirtbin

(make sure that you are on at least libvirt-bin version 1.2.2-0ubuntu11
and qemu-system-x86 2.0.0~rc1+dfsg-0ubuntu2 on that machine)

[Kent Stanwood Gordon (kent-gordon)]

starting/stopping libvirt-bin solved the problem
thank you for the help.

[Serge Hallyn (serge-hallyn)]

Thanks Kent.

It might be worthwhile to add 'trusty' as an alias for the new machine type, though not many people will created such a machine in the brief time that type existed.

[Waldek (rifster)]

Hi All,
I have similar issue to Kent's. Not much is on Google and I did all according to your posts and VMM still does not want to add a VM machine. I'm a linux newbie and there is definitely something I have missed. Please help. Thanks!

Hi,

It appears that your virt-manager is trying to create a pc-i440fx-2.1 machine type,
but your qemu version is 2.0, which only supports up to pc-i440fx-2.0. You should
be able to work around this by manually selecting the pc-i440fx-2.0 or
pc-i440fx-trusty machine type.

The default in virt-manager (we just tested) is pc-i440fx-trusty, so I'm curious
how precisely you created this VM? Did you simply choose all the defaults
when creating a new vm?

[Serge Hallyn (serge-hallyn)]

Hold on, I see:

> pc-i440fx-2.1 Standard PC (i440FX + PIIX, 1996) (default)

This suggests that you have a custom built qemu in your PATH
which is not in libvirt's PATH. What does

which qemu-system-x86_64

and

/usr/bin/qemu-system-x86_64 -M ?

show?

My guess is that virt-manager uses qemu 2.1 from your path to
detect machine types, chooses the newest available, then asks
libvirt to start that VM, but libvirt runs the 2.0 qemu which
can't start that newer machine type.

[Waldek (rifster)]

Hi Serge,
Before I saw your reply I manage to fix it by removing qemu from all location on my PC and reinstalling it again. Now it's working. You're probably right with two different paths. I compiled and installed qemu 2.1.2 and then also installed the package with 2.0. Thanks for your insight and have a good one!
