Description
Description
The guest fails late in the kernel guest boot when a TPM_CC_SelfTest is issued by the kernel. Since we are booting with multiple vcpus, I suppose the SVSM VTPM_REQUEST handler is not multi-thread safe.
This does not happen on every boot, but happened on 2/5 boots.
The guest boots fine with only 1 vcpu.
How to reproduce it:
Build the svsm.bin from either the dbuono-allocator-fix or svsm-vtpm-preview branches:
make FEATURES=verbose
Follow the README.md to build the other dependencies (make sure VTPM=1 is provided) and run the guest:
sudo ./launch-qemu.sh -smp 4 -hda ccguest.qcow2 -svsm ../svsm.bin -sev-snp -svsmcrb -allow-debug -ssh-forward
