You mention that this is hosted on an Altra but it looks like you're running the TCG backend, if there's some reason to expect that qemu might be unstable when hosted on that platform it's probably worth looping the qemu people in. --yRsqSy0P+bXdS5Uu Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmNzY5gACgkQJNaLcl1U h9CQzAf+IcSnHQ+8izD9i0xRCF2SV8pNK6d/Qa4aZblAfooRyn4EKZg+BuCepH1y siNIaqR6hKO8q1yqnrjSEDAfyYJVw3Gr9KEdmY2VvccFWeudquYSD4+QnmgvgJbz sLNHVCvirGKzvno1B1spCosYwFmElA74AfcbIrPBFhlwPQj8akU8ydB0tCy5lCLb eCS/NhD44VnQzJIQGHeJhFj4JsgqqlnF9WCl+QX7qkMKvtrMui97yOzom4ZAvpaU Adqtuecvus1r47qlYahceVJGsbWmFjYs+WIMEICyXNNrkzDgYRoGnm2kWibEWWTT 201nrRDJM/MK5QH/lK/NljHBDS+Mww== =myaL -----END PGP SIGNATURE----- --yRsqSy0P+bXdS5Uu--
