Just wondering what the significant differences were between doing
vzctl stop
vzctl start

and

vzctl restart

On a server when i do the initial two it has no issues:

[root@node0 ~]# service vz stop
Shutting down VE 101
Bringing down interface venet0: [ OK ]
Stopping OpenVZ: [ OK ]
[root@node0 ~]# service vz start
Starting OpenVZ: [ OK ]
Bringing up interface venet0: [ OK ]
Configuring interface venet0: [ OK ]
Starting VE 101: [ OK ]
[root@node0 ~]#


But when doing a vzctl restart:

[root@node0 ~]# service vz restart
Shutting down VE 101
Bringing down interface venet0: [ OK ]
Stopping OpenVZ: [ OK ]
/etc/init.d/vz: line 200: echo: write error: Broken pipe
/etc/init.d/vz: line 200: echo: write error: Broken pipe
Starting OpenVZ: [ OK ]
Bringing up interface venet0: [ OK ]
Configuring interface venet0: [ OK ]
Starting VE 101: [ OK ]
[root@node0 ~]#


Are these 'Broken pipe' errors anything to worry about?

197 conf="`zcat /proc/config.gz 2>/dev/null | grep -E -v '^#|^$'`"
198
199 for opt in $opt_must; do
200 if ! echo "$conf" | grep -q "$opt="; then
201 echo "ERROR: Missing kernel config option: CONFIG_$opt"
202 err=1
203 fi
204 done

As it doesnt actually echo any missing kernel config options so bit unsure as if restart is having an issue or not.
