I worked with David off-list on this, and it eventually turned out that the problems were hardware-related. The cluster consisted of two Librebooted x200 machines. One that happened to support KVM, and one that did not. The Libreboot wiki entry on the x200 states that there is only one known microcode revision that works with KVM: https://libreboot.org/docs/hardware/x200.html#compatibility_noblobs Interestingly, the failing machine did have the mentioned 1067a microcode version, whereas the other (functioning) node had 10676. The problem with 1067a manifests with QEMU starting, but not loading the guest OS. Live migrating a running VM to the 1067a node *did* work, adding to the confusion. Just "offline migration" and starting new VMs did not. I'm happy to report that the cluster works fine after replacing the dysfunctional node. :-) --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEu7At3yzq9qgNHeZDoqBt8qM6VPoFAl+CLmIACgkQoqBt8qM6 VPo4eggAq5onCw9x03Jmzn60/GU7NQ+UiZMYwPhdBoHcnEk6ZfGVDB0JmkClajXH XFgdapwJRqRsca+jZ1zJ5xE0ddlnfQM5oeD5yCup5peugnowbXn85EDgRLROTZ4j rtejbs7cGRr4QgBrBE20GxStfrnaNeBOkJrMHB7ygbdCU1yPWaRsxaxA/+tXE4i1 0BbYtpQYizH1keDRh8Zvd75xvQmfmn4jjTW+55Hh3oO0X/aE2U4FS8DlNHu3rnFn uOYgNQvA/AVJj+6OORy3L05++tJ5a69E/qRACtAwtT+v+WD3sLOWiYaJM8PSGC+L yNRwULWb59RB4Lw98FcBDJFGYqFqhA== =vzlr -----END PGP SIGNATURE----- --=-=-=--
