[lxc-users] lxc move fails

[jjs - mainphrame]

I've been hoping for a return of live migration functionality as well.
I tried after today's lxc upgrades, but no joy:

root at olympia:~# lxc move kangal lxd1:
error: Error transferring container data: checkpoint failed:
(00.614250) Error (files-reg.c:683): Can't dump ghost file
/lib/x86_64-linux-gnu/libc-2.19.so of 1840928 size, increase limit
(00.614252) Error (cr-dump.c:1356): Dump mappings (pid: 3572) failed with -1
(00.617439) Error (cr-dump.c:1600): Dumping FAILED.
root at olympia:~#

Both hosts are ubuntu 16.04, up to date as of this message.

Shall I file a bug report?

Jake
