Hello everybody. Thanks to this forum's people I could successfully migrate my Via EPIA server into a wonderful VPS. It works like a charm and I'm able to offline migrate it between my desktop (amd64) and my laptop (i386) in few minutes.
Now I'll put back a small OpenVZ minimal system on the Epia, ready to be pushed back.
I have one problem with online migration... here's the result:
root@desktop:~# vzmigrate -r no --keep-dst --online -v 192.168.5.146 2000
OPT:-r
OPT:--keep-dst
OPT:--online
OPT:-v
OPT:192.168.5.146

-.-.-.-.-.
The warnings I think are folded to different archs (amd64 and i386) between desktop and laptop. But...what does it happen? Why does it fail?
Google didn't help... thank you!

inside this VE and on HN?
Thanks,
