Config setup? - TD Quote from host is failing inside SVSM

[oriordain-s]

Hi folks,

I have followed directions for ingredient building as per documentation in:
https://github.com/intel-staging/td-partitioning-svsm/blob/svsm-tdp-vtpm/Documentation/TDP-VTPM.md
and
https://github.com/intel-staging/td-partitioning-svsm/blob/svsm-tdp-patches/INSTALLATION_GUIDE.md

See txt file attached for output from running the launch script from the host (Ubuntu 24.04).

Launch script used is quite similar to:
https://github.com/intel-staging/td-partitioning-svsm/blob/svsm-tdp-patches/INSTALLATION_GUIDE.md#sample-tdp-guest-launch-script

From a tad further debug, it's running into failure after call to:
generate_vtpm_certificates: quote_generation: get_quote_from_host: tdvmcall_get_quote
Is this a known issue? If not, would appreciate pointers to possible fix.

Many thanks.

Ok, folks, this issue can be closed - the quote tdvmcall was not getting caught by qgsd daemon on the host.
Need the correct qemu setup parameters when launching.

-machine q35,accel=kvm,kernel-irqchip=on,hpet=off,pic=off,pit=off,sata=off,l2bios=${L2BIOS},confidential-guest-support=tdx0 \
