Fedora - KVM - qemu - Windows 11 guest. error: swtpm at /usr/bin/swtpm does not support TPM 2

 you cannot create and execute VM: Windows 11 Guest in Fedora 40? 

it's SELINUX. you can disable SELINUX or create a rule to avoid the TPM problem. we choose the second one. 

check

• sudo ausearch -c 'virtqemud' --raw

or

• sudo ausearch -m avc -ts recent

if results appear, go on

solution:

• sudo ausearch -m avc -ts recent | grep virtqemud | sudo audit2allow -M local_virtqemud
• sudo semodule -i local_virtqemud.pp
• systemctl restart libvirtd
