CRIU team,

I watched the cool CRIU video on youtube and presentation:

I'm using vnc4server with a shell and a UI app running like this:

 1770 pts/2    S      0:04 Xvnc4 :2 -desktop ip-16-118-238-44:2 (ubuntu)
-auth /
 1776 pts/2    S      0:00 vncconfig -iconic
 1777 pts/2    S      0:00 xterm -class UXTerm -title uxterm -u8 -geometry
80x24
 1784 pts/3    Ss     0:00  \_ -bash
 2119 pts/3    Sl+    1:51      \_ /mnt/mydata/MYAPP

I then do a dump on "1770", but get an error:

Error (parasite-syscall.c:387): si_code=1 si_pid=2328 si_status=0
Error (parasite-syscall.c:387): si_code=1 si_pid=2330 si_status=0
Error (cr-dump.c:386): Task 1770 with SysVIPC shmem map @7f3a4de0b000
doesn't live in IPC ns
Error (cr-dump.c:1588): Dump mappings (pid: 1770) failed with -1
Error (cr-dump.c:1870): Dumping FAILED.

I can post the -v4 log, but wanted to check if my fundamental setup is
correct or if there are any limitations. I'm open to any kind of vncserver,
window manager, etc.
