By default Microsoft updates installed on Virtuozzo host are applied in containers during next containers start.
If auto applying Microsoft updates in containers is unnecessary option it is possible to configure containers to not install updates even if its are on Virtuozzo host.
The following example shows how to disable this auto applying option for container 100:
vzcfgt set 100 DisableWindowsUpdates 1
If this option is set to “1” no more windows updates will be applied to the container 100.
But you can still manually install or remove windows updates to this container by using Container Update Manager.
To find Container Update Manager click Start button on the node and go to All Programs, Parallels, Parallels Virtuozzo Containers.
The command below enables auto applying option for container 100:
vzcfgt set 100 DisableWindowsUpdates 0
Also it’s possible to disable auto applying option for all newly created containers on a node:
vzcfgt set 0 DisableWindowsUpdates 1
Note: If it’s necessary to enable the auto installation of windows updates back in containers you should re-configure each container separately.
