let me check, hmm ...
0.30.214 released September 2007
0.30.215 released March 2008,
2.6.32 kernel, released December 2009

so yes, you need to update util-vserver and no
neither 0.30.214 nor 0.30.215 will work with
a kernel newer than 2.6.22 mainly because the
namespaces were not part of the kernel back
then ...
