I had to time to dig it, putting a network TAP on the wire. It seems to be a network issue because no ARP packet runs on the wire for eth1 (dedicated to iSCSI). So it's not a libvirtd problem, I think that this problem can be marked as solved. ARP works very well for the orther interface linked to a casual network. > What kind of iSCSI target is this?

Maybe there is a custom setting for MTU and this switch. > > Cheers, Thanks for your help Guido, Regards, > -- Guido > > - -- Nicolas Greneche - RSSI et Sysadmin Centre de Ressources Informatiques (CRI) Doctorant au sein du projet SDS - www.sds-project.fr Mail : nicolas.greneche_(at)_univ-orleans.fr GPG : http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x5FEBD0EF Universite d'Orleans Web : http://blog.garnett.fr Batiment 3IA - 2e etage Tel : 02 38 49 25 26 6 rue Leonard de Vinci BP 6102 45061 ORLEANS Cedex 2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkunlgMACgkQTx/Y+1/r0O8FyQCgn26RTA2bH8bbXEhYc9DBdMzz qsoAn2M6cOmdpv35XCiQuAhHS8wSh/G6 =8cwA -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
