Hello, some days ago I followed these instructions https://sigs.centos.org/virt/tdx/host/ and after enabling the repo I installed the tdx necessary bits as indicated, with the command

dnf install kernel-tdx qemu-kvm-tdx libvirt-tdx

This gave me:

libvirt 9.5.0-1.el9s qemu-kvm 8.0.0-15.el9s kernel 5.14.0-395.el9s

But now if I run a usual "dnf update" I'm proposed "standard" libvirt and qemu-kvm sw stack, I think because of their version apparently greater (10 vs 9.5 and 8.2 vs 8.0):

What is the best option to blacklist the packages in appstream and prioritize the tdx ones?

I tried adding priority=1 to the tdx repo file, but now I get this when running "dnf update": Error: Problem: package python3-libvirt-10.0.0-1.el9.x86_64 from appstream requires libvirt.so.0(LIBVIRT_9.7.0)(64bit), but none of the providers can be installed - cannot install both libvirt-libs-10.0.0-2.el9.x86_64 from appstream and libvirt-libs-9.5.0-1.el9s.x86_64 from @System - cannot install both libvirt-libs-10.0.0-3.el9.x86_64 from appstream and libvirt-libs-9.5.0-1.el9s.x86_64 from @System - cannot install both libvirt-libs-10.0.0-4.el9.x86_64 from appstream and libvirt-libs-9.5.0-1.el9s.x86_64 from @System - cannot install both libvirt-libs-9.10.0-1.el9.x86_64 from appstream and libvirt-libs-9.5.0-1.el9s.x86_64 from @System - cannot install both libvirt-libs-9.9.0-1.el9.x86_64 from appstream and libvirt-libs-9.5.0-1.el9s.x86_64 from @System - cannot install the best update candidate for package python3-libvirt-9.3.0-1.el9.x86_64 - cannot install the best update candidate for package libvirt-libs-9.5.0-1.el9s.x86_64 (try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) #

Currently I have python3-libvirt-9.3.0-1.el9.x86_64 installed. Thanks for any advise
