[Users] Live Migration Fails

[Kirill Korotaev]

Can you post output of dmesg here plz?
Looks like your installation somehow broken.
I can hardly imagine why sed should normally  catch SIGSEGV.
Maybe it is compiled for some more modern CPU than you use on destinaton machine?
Or vice versa - maybe you use ancient distribution in VE?

So plz provide more info like what OS distribution is running inside VE,
dmesg output, and what other error you experienced during online migration
after fixed vzmigrate as Thorsten suggested?
