Virtuozzo VZPP and Plesk services not available in Node- Resolutions

There are several reasons for VZPP and Plesk service failing on Node

Here are a list of resolutions which might help us

1) If this is for an Individual container (Apply commands for containers):
vzctl set CTID --offline_management no --save

vzctl set CTID --offline_management yes --save

2) If VZPP and Plesk services does not work for all containers:

Try restarting ServiceCT - (vzctl restart 1)

Try restarting vzoap service-

net stop vzoap

net start vzoap

Finally try recreating ServiceCT by following the procedure:

Check if unrequired Microsoft security updates are installed on the Node:Like update KB938464

Uninstall the update and install if any new Virtuozzo auto updates are available

Reboot the node

After reboot, stop Service Ct for recreation

vzctl stop 1

Destroy Service Ct -> vzctl destroy 1

Recreate ServceCT-> vzsveinstall -s IPADDRESS -w -f

Apply the commands for all containers

vzctl set CTID --offline_management no --save

vzctl set CTID --offline_management yes --save

After applying the commands VZPP and Plesk services should work fine
