Recreated the list with a better container :-/
#1 Bionic - as-is (libvirt 4.0 qemu 2.11) - Container -> Big List
#2 Bionic + Stein (libvirt 5.0 qemu 2.11) - Container ->
#3 Bionic + Train (libvirt 5.4 qemu 2.11) - Container ->
#4 Bionic + Focal-Binaries (libvirt 6.0 qemu 4.2) - Container ->
#5 Bionic - as-is (libvirt 4.0 qemu 2.11) - on Host -> Big List
#6 Focal - (libvirt 6.0 qemu 4.2) - Container - -> Big List
All confusion gone!
Ok that were a lot of checks to realize a simple truth.
The Eoan container I had initially thought I see your problem had no KVM as
well :-/
But that might still help us as now I know rather exactly what to ask for.
Maybe your system doesn't detect KVM or some cpu flags correctly.
1. please provide the output of
$ kvm-ok
2. please provide the output of
$ sudo qemu-system-x86_64 --enable-kvm --nographic --nodefaults -S
-qmp-pretty stdio
{"execute":"qmp_capabilities"}
{"execute":"query-cpu-definitions"}
In my systems case I can't select Skylake as well and the report tells me:
{
"name": "Skylake-Client-IBRS",
"typename": "Skylake-Client-IBRS-x86_64-cpu",
"unavailable-features": [
"hle",
"rtm"
],
"static": false,
"migration-safe": true
},
Which is a known limitation due to
https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-11135.html
As discussed in https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1853200
this is a Won't Fix at the moment. But we could bump that bug and report this
case "symptom" to reconsider adding e.g. a reduced Skylake type.
Waiting for your data first ...
