Update vzkernel newbie

Update only vzkernel on Centos.

Check the bootlist:

cat  /boot/grub/grub.conf

Proceed with update:

yum update vzkernel

Check the bootlis again and note that new kernel appeare to load at the next boot:

cat  /boot/grub/grub.conf

For any case count how much active vps now:

vzlist | wc -l

You may save the output in order to be able to compare it with the same command output after reboot/all vm start

vzlist | wc -l >/tmp/vzlist.txt
vzlist >>/tmp/vzlist.txt 

Reboot:

reboot

Once reboot finished take a look into /var/log/vzctl.log and /var/log/messages you may do it in two separte ssh sessions with tail -f command.

update vzctl vzquota ploop for better workaround.
