kvm groupadd GID already exists

[pcrutcher]

My KVM GID is 104, which apparently conflicts with an existing group within the container(?):

I added "-o" to the groupadd command in DockerFile and it seems to be working. Not sure if there are side effects, but the build completed and the IDE launched successfully.
