Right now to get around the problem I returned to the official stretch
packages, and I'm using the Opteron_G1 / kvm64 / qemu64 cpu. I have no
errors in the guest machine, while on the host machine this message
appears when the guest machine is booted:
kvm [61880]: vcpu2, guest rIP: 0xffffffbb8595c2 unhandled rdmsr: 0xc0011029
this error appears during the loading of the kernel
Guest debian stretch 4.9.0-6-amd64
I tried to go back to version 4.9.0-4-amd64 and this error does not
appear because?
Should I report only this last in the kernel section?
Thank you

After a bit of high load, I immediately notice the dumps on both the
guest and the host machine:

and now I can confirm that if in the host system if the CPU is
configured "copy host CPU configuration" the system now recognizes
the EPYC cpu (but if I look in the list the EPYC model from libvirt
is not displayed, it does not matter).
Then, with the guest system started, the EPYC CPU model is displayed,

There remains only a defect on the host machine that once started
appears this error, can you help me to understand what could be?
HOST DMESG

However, in the future this solution may not work because the gap
between the buster and the stretch may be wider, so the dependency
chain may break.

I agree that the change should be made for both libvirt and qemu, in
fact I know that this escalation was made.

I could use the emulation of another cpu to remedy the problem, but
instead of having a supercpu without introducing transcoding of the
processor I would have very degraded performance.
Another solution would be that as you mentioned to use buster
packages, I try to install the new packages and I hope I do not run
into an endless series of installs for library dependencies.
In the meantime, I thank you for your time and I will keep you updated.

As far as I read this it's not related to the problem you're seeing and
if we add this qemu woul need support as well:
https://bugzilla.redhat.com/show_bug.cgi?id=1445834
but is should work without it nevertheless using another CPU model.
This:
kernel: [ 2.623548] kvm: no hardware support
means likely that virtualization is not enabled on your machine. Can
you run accelerated VMs using only qemu but not libvirt? Does it work
with debian buster?
