Hello list !
I got a problem concerning migration of domUs.
After starting migration with ''xm migrate domdirectinstall
xxx.xxx.xxx.xxx'' domU appears at xm top as
''migrating-domdirectinstall'' (Source) and as
''domdirectinstall'' (Target).
But then nothing happens. It seems that the command hangs up. So logging up on
the consol with ''xm console migrating-domdirectinstall'' (Host)
I got the following output on the console.
talaos:~ # xm console migrating-domdirectinstall
Setting mem allocation to 131072 kiB

Host is a P4 and target is pretty old Athlon at 1GHz, but architecture should be
the same (x86) or am I wrong at that point.
