  "message": "pc: Disable vmdesc submission for old machines\n\nOlder PC machine types might by accident be backwards live migration compatible,\nbut with the new vmdesc self-describing blob in our live migration stream we\nwould break that compatibility.\n\nAlso users wouldn\u0027t expect massive behaviorial differences when updating to a\nnew version of QEMU while retaining their old machine type, especially not\npotential breakage in tooling around live migration.\n\nSo disable vmdesc submission for old PC machine types.\n\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\nReviewed-by: Dr. David Alan Gilbert \u003cdgilbert@redhat.com\u003e\nSigned-off-by: Juan Quintela \u003cquintela@redhat.com\u003e\n",
