[ovirt-users] ovirtmgmt network security

[Luca 'remix_tj' Lorenzetto]

Sorry,

But you didn't understood well what i've said.

If your host has no ip addresses on that network, you're not encountering
any risk because you've no access to that network at layer 3.

Removing ovirtmgmt is not possibile, that network is mandatory.

Hello,

I totally agree on the First part: IP set only on the VM.

For the ovirtmgmt access, if I understand correctly, I have to choose
between sécurity and ease of management of my VM but I can not have both.

Hello,

On the dmz Network you don't need any address configured on the host.

You set ip address only on the vm. If the vm gets compromised, its access
is limited only to DMZ Network.

 There is no way for the attacker to gain access to ovirtmgmt if vm is not
configured to use it.
