RESOLUTION
As part of the Virtuozzo installation, the following registry key and values are set to point our servers where only approved Microsoft Updates are available:HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
"WUServer"="http://vzwinupdate.sw-soft.com"
"WUStatusServer"="http://vzwinupdate.sw-soft.com"
Starting from Parallels Virtuozzo Containers 4.0 it is possible to configure VUS ( Virtuozzo Update Service which provides with the same functionality as WSUS, but for Virtuozzo updates). The following registry key and values are configured in this case:
HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\VZUpdates\\DefaultURL
HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\VZUpdates\\URL
Note: In Parallels Virtuozzo Containers 4.0 , all these settings could be configured through GUI as well. To do that , please run Virtuozzo Update Wizard and go to Proxy Settings.
