答复: [Xen-devel] Xen Live Migration Fail
Did you modify the xend-config.sxp correctly? Those comments in the
discussion thread below, could be helpful for your question.

<<[Xen-devel] Xen Live Migration Fail
Dear all:
I am trying to migrate a WinXP HVM (64M memory) from a machine
(sender) to another machine (receiver) through AoE disk, however, there are
some errors when do the following command:
(My xen version is xen-4.0.1-rc5.hg, kernel 2.6.31.13, xen
xen-4.0.1-rc6-pre, Both sender and receiver are the same xen version)
xm migrate --live domain_id receiver_ip
===============================================
The error message at sender side is:
Error: timed out
Usage: xm migrate <Domain> <Host>
...
===============================================
Then, I read the xend.log (sender) and find this error message:
===============================================

===============================================
And the qemu-dm.log gives a "buffer overflow" message as following:
===============================================
...

===============================================
The logs are also attached. Any ideas or patches to fix this problem ?
Thanks!

Tang-Hsun Tu
