Hello,

I'm trying to migrate a container to another hardware node but without success after few tries.

The message I get is:

Setting CPU limit: 400
Setting CPU units: 1000
Setting CPUs: 4
Error: undump failed: Too many open files
Restoring failed:
Error: can't open file pipe:[76632562]
Error: rst_file: -24 3985376
Error: rst_files: -24
Error: make_baby: -24
Error: rst_clone_children
Stopping container ...
Container start failed
Container was stopped
Container is unmounted

Command used to migrate is: vzmigrate -r no --keep-dst --online -v HN CTID

- kernel version is: 2.6.18-274.7.1.el5.028stab095.1 on both hardware nodes.

Also if you think I should try to migrate with container stopped please tell if this are the correct steppes:

- rsync -vlHogDtpr --delete --numeric-ids /vz/private/CTID root@HD2:/vz/private/
- vzctl stop CTID
- vzmigrate -r no --keep-dst -v HN CTID

Because downtime is important I'd like to migrate with online method but maybe offline is the only way Sad
