Additional info: 1)after migrate finish.the src spice client is normal ,can see the screen again 2)test this with windown2008,also have the same problem 3)use vnc to test the src client work well. do the same test on rhel6.3 host ,not hit the issue.the src spice client work well.

Hi, you mean that the client is closed everytime migration occurs? Please provide the qemu logs for both the migration src and the migration destination. Also provide the spice client log (under ~/.spicec/spicec.log). The destination is rhel5 as well? The issue to be investigated here is the client being disconnected from the src. The black screen upon reconnection to the src during migration is not surprising, since in Rhel5 spice blocks new connection once migration has started. Thanks, Yonit.

Hi, I think your migration cmd line is incomplete. In rhel5, in order to include spice in the migration, the cmd line should be: migrate -d tcp:<dst-host>:<dst-port>,spiceport=<dst-spice-port>,spicehost=<dst-host> Please let me know if now it works.
hi!Yonit you are right.use cmd line "migrate -d tcp:<dst-host>:<dst-port>,spiceport=<dst-spice-port>,spicehost=<dst-host>",it work now.not show dark screen.thanks a lot.
