Correct way to move kvm vm?

I wonder if someone can give me a pointer on where in this seemingly straight forward process I’ve gone awry. I’ve taken a quick pointer from this brief Server Fault post.

But, on the two machines I’m moving I end up with:

error: Failed to define domain from Win7.xml
error: unsupported configuration: domain configuration does not support video model 'qxl'

EDIT: Oops, should have done more home work on that one, answered here a year ago…

And this one’s coming from a Debian (PureOS) based system - I wonder if binaries are in a different place or name? which qemu-system-x86_64 or qemu-system brings up nothing:

error: Failed to define domain from Android-x86-9.0.xml
error: Cannot check QEMU binary /usr/bin/qemu-system-x86_64: No such file or directory

Here’s the whole process:

I weep - what a absolute total flipping mess!
(I realise I’m late to the party - would have been sooner if RH hadn’t dropped hardware support in 9 for my old laptop pressed into service as server…)
After close to 20 years of Fedora I started looking for a bit more stability a couple of years ago and all I’ve found since is a mess…

Is the Jean-Marc Liger’s Paris City Uni copr repo the best answer atm?

EDIT:
dnf -y copr enable ligenix/enterprise-qemu-spice ; dnf update

[root@server ~]# virsh define Win7.xml
Domain 'Win7' defined from Win7.xml

[root@server ~]#

Hope so…

The binary seems to be: /usr/libexec/qemu-kvm in EL.

What I did was to first remove all QLX & spice devices from the VM in virt-manager that it could and switch graphics to “vnc” (and video to ‘virtio’). If something did block that, then virsh edit domain_name
to delete the offending bits. That is, convert away from QLX/sprice before the move.

Thanks @jlehtone - I actually installed the copr repo and that seems to doing the job while I scratch my head (again). It seems to be getting recent attention and updates.

I tracked down the binary too - it seems it moved from the bin to libexec location a few years back on rpm distros - but, there’s not much on that Android anyway and I might just reinstall it. Many thx, M
