How Many Logical networks supported
Hello, We are currently using oVirt for teaching and one of our requirements is for security such as IR PEN testing etc. We would like to create individual logical networks with a network profile that includes port mirroring, this is to reduce the amount of traffic they can see and the targets available. We are looking to to add VMs into Affinity Groups so they will run on the same host to make the port-mirror work but don't no if there is a limit on the number of logical networks that is allowed/practical. Thanks, Regards, Paul S.

But I ensure check if the boot and configuration times are acceptable, if many logical networks are used. I would be interested to know if using OVN via ovirt-provider-ovn is helping to speed up boot and configuration times. But I expect port-mirroring is more complex in OVN.
Thanks Dominik, I will check on the ORB configuration first, I know that different hardware switches have a maximum number of VLANs that can by active. I will also see if there's a limit in the linux-bridge or libvirt. I was going to look at ovirt-provider-ovn next but when I upgraded our engine it failed to configure it therefore I left it out since we weren't using it. Regards, Paul S. P.S. 0x000 and 0xFFF are reserved to the maximum is 4094 ________________________________________ From: Dominik Holler <dholler@redhat.com> Sent: 12 October 2018 09:00 To: Staniforth, Paul Cc: users@ovirt.org; Petr Horacek Subject: Re: [ovirt-users] How Many Logical networks supported On Thu, 11 Oct 2018 11:31:04 -0000 p.staniforth@leedsbeckett.ac.uk wrote:
