[Xen-devel] linux 2.6.35.4 pvops failed to live migrate

[Vasiliy G Tolstov <v.tolstov@xxxxxxxxx>]

Hello. I'm try to live migrate bare linux 2.6.35.4 (pvops) from one host
to another. But migration stopped and in /var/log/xen/xend.log displays
message:


[2010-09-21 10:10:15 9569] ERROR (XendCheckpoint:188) Save failed on
domain testing (19) - resuming.

1459, in _domain_migrate
    dsterr = sock.recv(1024)

Why this happened? Do i need some patches to correct save/restore under
domU?
