  Add ‘Enable shared memory’ UI checkbox (Lin Ma)
  add UI preference to default to UEFI for new VMs (Charles Arnold)
  Add virtiofs filesystem driver UI option
  Fill in all –cputune, –cpu, –shmem, –input, and –boot suboptions (Hugues Fafard)
  virt-* mdev improvements (Shalini Chellathurai Saroja)

  Revive network portgroup UI
  enable a TPM by default when UEFI is used (Daniel P. Berrangé)
  Use cpu host-passthrough by default on qemu x86
  use virtio-gpu video for most modern distros
  Default to extra pcie root ports for q35
