here is example from my test node,
uname inside fedora-27 -based container was adjusted based on content of osrelease.conf

[root at vvs-ovz6 ~]# uname -a
Linux vvs-ovz6.sw.ru 2.6.32-042stab132.1.vvs.psbm87155v12 #1 SMP Mon Aug 13 19:28:24 MSK 2018 x86_64 x86_64 x86_64 GNU/Linux

[root at vvs-ovz6 ~]# grep TEMPLATE /etc/vz/conf/177.conf 
OSTEMPLATE="fedora-27-x86_64-20171116"

[root at vvs-ovz6 ~]# grep fedora-27 /etc/vz/osrelease.conf 
fedora-27       4.14.0

[root at vvs-ovz6 ~]# vzctl exec 177 uname -a
Linux vvs-ovz6.sw.ru 4.14.0-042stab132.1.vvs.psbm87155v12 #1 SMP Mon Aug 13 19:28:24 MSK 2018 x86_64 x86_64 x86_64 GNU/Linux
