Re: [Xen-users] Problems starting xfrd to migrate a domain

[Miguel Gómez <elmiguelonmakinon@xxxxxxxxx>]

Ok, things seem to get better. I was using the pre-built Xen
installation. When I compiled the source  distribution,
save/restore problem disappeared. But I can not still migrate domains.
When I have a ttylinux domain like this:

XENslave:/xen# xm list
Name             
Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0          
0       26    0 
r----    107.3
ttylinux2        
11        7   
0  -b---      0.3    9611

I try to migrate it with:

XENslave:/xen# xm migrate ttylinux2 192.168.50.194

And look what I get in the destiny machine /var/log/xfrd.log:

It looks good!!!, but when I do a "xm list" in the destiny machine:
XENmaster:/etc# xm list
Name             
Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0          
0       26    0 
r----     76.7

Something is wrong, do you know what I can do? Where can I search for the problem? 

Thank you, everybody, for your help and have a nice weekend!!!!
