About the Security groups

[leo79901]

I have installed an ACS with 'Core - Basic' zone. When I want to change the VM's name, display or other information, ACS tells me that I cannot change the security groups.
Is this correct?
Meanwhile, can't I change the security groups while the VMs are running? If this is true, I have to create a new security group for every VM.

@leo79901 You should be allowed to change or display the name on a running instance. This error seems to be a bug with the basic zone only or any instance with a security group. Do you mind creating an issue ticket?

You have to stop the instance to change the security group.
You can use one security group for many instances.

it looks like the restriction was added 8 years ago and it is still there

Thanks a lot. In order to provide more flexible security protection, before it possible to adjust the security groups when the machine is powered on, I will create a separate security group for each host.

@leo79901 if you do it from cmk/cloudmonkey does it work?

[leo79901]

Yes, i have do it again using CloudMonkey. The name was changed successfully.

in my opinion,

• the first issue is a bug. since security groups cannot be changed when vm is running, we should hide the field in the dialog.
• the second can be a improvement request: Update security group lists of a running vm
