When I run "vzlist" command on Parallels Containers host I am getting the following errors:

C:\Users\parallels>vzlist -a

There is no Virtuzzo container installed.

User account which I use to log into the host has administrator rights.


The reason of the errors is enabled User Access Control (UAC) on the server. To avoid the issue it is necessary to disable UAC or run vzlist command using "run as" feature.
