Vitaliy, Thank you for your answer. I think i have made myself missunderstood. When I create a category and say that I want to work only with VMs on that category, there is a default group called UNCATEGORIZED. Than one holds all the vms published in the virtual infrastructure. To categorize the VMs i have to create some extra folders and assign the VMs to each folder. This way the VMs will be, lets say, removed from UNCATEGORIZED section and moved into the Folder i chose. The idea is that in the VM section -> Details i see only the VMs which have not been categorized, and this is ok. Here comes the tricky part. If I create a new categori, and I want to work also with VMs, I will have a new default group called UNCATEGORIZED. If I go to VM -> Details and try to assign a VM to a folder created in the second category, I will see that the VMs which have been assigned to the first category can be assigned to the second category as well, and if i create 10 categories, all of them will have a group called UNCATEGORIZED and for each VM I will still have 9 possibilities to assign that VM to another category (10 - 1, 1 is the group to which that Vm has ben assigned to). So what I want to do is:
1. Create a category (i did)
2. Create a group or more in a category (i did)
3. Assign to each group some VMs (i did)
4. Remove the VMs i do not need from the defaul group called UNCATEGORIZED (i do not want to see the VMs i do not need for that category in VM -> Details section, where I assign each VM to a group)
Do you understand me? I have tried to explai this as best as possible.
