Self-service users cannot select VM Network after updating VMM to UR3

Since we updated VMM 2019 to UR3, self-service users are unable to select a VM Network - they click browse, select the VM network and when trying to confirm the change, they receive the following error: "Either Allowed VM Network or Native VM Network is not selected. Select Allowed VM Network and Native VM Network for Trunk Vlan, and then try the operation again"

We're not trying to use the new trunk mode that was added in UR3, just simply select a VM network for an adapter. A user with the full Administrator role can select the VM Network just fine (and also sees the "Enable Vlan" checkbox that the self-service user doesn't).

Is this some new bug introduced in UR3? Is there a way to work around it (under the self-service user context)?

I am also having the same problem.
In some cases, the vmm console crashes..

It might be a Microsoft bug but here is what I did to get around the error message. Check the box for Trunk mode and select the corresponding VM network. Select OK. Wait for VM to finish updating. Go right back into the properties of the VM / NIC and uncheck the Trunk Mode box and select OK again. Dumb workaround but it does work for me. BTW, I am also running UR3.

BensonDougJDPI, I tried your suggestion, but it does not work for me, I get the same error when I check the trunk mode and select any vm network.

Sorry my suggestion didn't work for you. My VM 2019 setup is a brand new installation on a new Windows 2019 server and I migrated my existing clusters over to it. I also found out that Windows Update doesn't update the server component of SCVMM, only the console. You have to manually update the server installation. You might have already done that but I am throwing out suggestions hoping one might be your issue. The only other thing I can suggest is to look in the console at Settings --> User Roles and compare an account that works to the account that doesn't work and check each box (one at a time) that is unchecked on the account that isn't working and test each change until it works. If that still leaves your issue unresolved then you probably need to open a ticket with Microsoft to troubleshoot your logs. Good luck!

It doesn't work for me either. When selecting trunk mode and specifying vlan, the network is connected, but I cannot access the VM property. A console crashes and closes unexpectedly.

So it seems the behavior is different for all three of us, for me, the console doesn't crash, but doesn't even allow the config change.

For reference, mine is VMM 2019 UR3 2-node cluster deployment on WS2019.

I can try to fiddle with role permissions, but there's not much that could be changed, without affecting what the role members should/shouldn't be able to do.

This is definitely a GUI bug in UR3! I was able to work around it and get the configuration applied simply by making edits to the Properties. But instead of clicking OK, click View Script, which outputs all changes to a temporary text file. Drop those cmdlets into PowerShell; it took them without complaint and the jobs ran. Closing and re-opening Designer confirmed the changes were applied to the Service Template.

I have scvmm 2019 too with ur3. When I added a new nic to a VM with some kind of vmnetwork I got this messege too, but when I added new nic notconnected "mode" --> OK, then reopened hw settings window and set VMnetwork separately, it worked. Good Luck!
