The 2nd link is pretty interesting if your HW/OS supports VF and it does
contain the note about making MacVTap work. If you're concerned about the risk
warning you can get it via web archives here (though it may take a while to
load) :

NB. virt-manager is only a gui/tool for managing VMs under qemu/kvm (linux
host as a type 1 hypervisor effectively) whereas VirtualBox is a type 2
hypervisor (running under the host) and gui in one .. so most of your issues
with virtualisation are going to be qemu/kvm related rather than virt-manager
related. You do get near native performance in your VMs with qemu/kvm though.
There are other tools for managing your qemu/kvm VMs - see

H, thanks for the tips.
It is a simple selection/option in VirtualBox, a nobrainer selection.I'll read
the first link, bur the second gives a security warning, so I'll skip.
I wish there is a simple choice in virt-manager UI too.
Best Regards.

Not sure this is a virt-manager question: probably more of a general virtual
networking question.
Curious: Did you have this in VirtualBox ?
Anyway, I'd look at MacVTap - Linux Virtualization Wiki

- " Typically, this is used to make both the guest and the host show up
directly on the switch that the host is connected to."
.... I tried it in RHEL 8.4 (at the time) but had unworkable performance issues
but later found a note about "intel_iommu=pt" at
https://www.linuxsecrets.com/3417-creating-kvm-virtual-passthrough which might
address that. ( the VF stuff there not supported in RHEL last I looked )
Currently I use PCI passthru to use a 2nd host NIC directly in a VM but then
that only works for 1 VM so if you have an unspecified number of VMs that's not
gonna work for you.
Sorry can't be of more help.

Hi,
I've switched from VirtualBox to Virt Manager and I need to have virtual
machines in the same subnet as the host.How could I achieve that? I've spent
all day looking at various articles on how to do that, but I could not manage
to achieve it.Is there a reliable step by step procedure?I use a Gentoo
derivative.
Thank you,
Mihai Sorin Dobrescu
