Does your last sentence mean "CT can be in running and suspended state" 
i.e. 'vzctl status' has to show 'exist mounted running suspended'?
I've just tried to reproduce that state following [1] guide. So I did:
$ vzctl create 103 --ostemplate centos-5-x86
Creating container private area (centos-5-x86)
Performing postcreate actions
Container private area was created

$ vzctl start 103
Starting container ...
Container is mounted
Setting CPU units: 1000
Container start in progress...

$ vzlist
       CTID      NPROC STATUS    IP_ADDR         HOSTNAME
        103          6 running   -               -

$ vzctl chkpnt 103 --suspend
Setting up checkpoint...
         suspend...
         get context...
Checkpointing completed succesfully

$ vzctl status 103
CTID 103 exist mounted running

$ vzlist
       CTID      NPROC STATUS    IP_ADDR         HOSTNAME
        103         12 running   -               -

$vzctl chkpnt 103 --dump --dumpfile /vz/dump/dump.103
Setting up checkpoint...
         join context..
         dump...
Checkpointing completed succesfully

$ vzlist
       CTID      NPROC STATUS    IP_ADDR         HOSTNAME
        103         12 running   -               -

$ vzctl status 103
CTID 103 exist mounted running

As one can see 'vzctl status' doesn't show running CT as suspended. So 
what is the proper way to detect that state (running and suspended CT)?

Software versions used:

$ rpm -q vzctl
vzctl-3.0.26.3-1

$ uname -rsvpi
Linux 2.6.18-238.9.1.el5.028stab089.1 #1 SMP Thu Apr 14 14:34:26 MSD 
2011 i686 i386
