Bug description:
  While using VMM to create a new VM with TPM and UEFI boot, I am unable
  to create that VM.

  Symptoms:
  * While creating a VM with TPM, I get the following error:

  Unable to complete install: 'Cannot recv data: Connection reset by
  peer'

  Traceback (most recent call last):

  Other VMM VM creation details: all I have tried trigger it but try
  Jammy Desktop ISO, memory 8192, CPUs 2, accept other defaults,
  customize installation, firmware secboot, add hardware -> TPM with
  defaults, begin installation
