would be helpful to know in what stage the vzmigrate-process was, when the task got stuck, eg. post it's stdout, logs.

check the harddisks/raid controller that have read/write activity during vzmigrating (smart-values, controller logs).

try if you can get a program that produces a lot of I/O (eg. iozone3 or tar) to get stuck as well.

it looks like you are migrating your VPS to 10.10.10.11 and when starting the container it is given the same ip address 10.10.10.11.
