swtpm emulated tpm) not found on Win 11 VM (KVM) after Syu 10 apr

Hi folks
I usually run a system update once a week (pacman -Syu)
Ran it today -- and I run some Windows 11 VM's which need a TPM - was using the swtpm package.

Working properly on 6 Apr

Windows 11  VM's  now reporting no TPM found after update (Pacman - not Windows) on 10 Apr

Not sure if it's possible to post image - but no errors reported on the system upgrade

in Windows 11 VM running  the command tpm.msc  normally shows details of teh tpm -- IBM etc. now it says No TPM module found.

I rolled back to 6 Apr where its OK -- then tested update again ignoring swtpm libvirt qemu

still didn't work

So back to Apr 6 -- I need these Windows 11 VM's so any ideas anybody.

(I'm running the wayland/Xorg plasma as GUI - KDE) on my arch system).

Thanks

Did you also ignore libtpms?

libvirt is the only package you ignored that had an update this week. The last update for qemu was in february, the swtpm/libtpms was in march.
It was only a rebuild of the same version, so it was unlikely to be the cause and you proved that.

Which packages were updated this time around according to your pacman log?

Compiling edk2 with -D TPM2_ENABLE -D TPM2_CONFIG_ENABLE fixed the issue for me so i'm guessing what broke with the update was that.
