[libvirt-users] virDomainMigrate() leads to SASL error

Hello, I'm trying to use virDomainMigrate() function through libvirt-php but I have this error coming from libvirt (this is an error raised by virDomainMigrate(), not by php binding) : Failed to step SASL negotiation: -7 (SASL(-7): invalid parameter supplied: Unexpectedly missing a prompt result) My two connections are over TCP with login/password provided (URL is qemu+tcp://X.X.X.X/system) Connection to both hosts independently is working (listing domains, etc.) Migration through virsh is working too ! On destination host, I have this in log file : 2012-08-09 14:29:23.628+0000: 17179: error : virNetSocketReadWire:1003 : End of file while reading data: Input/output error Can someone tell me if I'm doing anything wrong ? Thanks ! Olivier
