Qemu-KVM. Host and guest do not see each other through macvtap(VEPA), why?

Question

linux

Hello.
Faced strange behavior.
There is a host 14.04 desktop.
Network network 172.20.5.0/24 DHCP details.
The host hypervisor receives the props and successfully goes online, all neighbors are available in the eth domain.
I create a guest (it doesn't matter what OS, I checked it on ubuntu 16 & win 7).
I create a network connection eth0:macvtap(VEPA (although everything is the same with the bridge))

And so I start the VM, the interface successfully rises on the hypervisor host The macvtap0
guest receives the details, can go to the Internet and pings any host in the eth domain 172.20. -hypervisor.
But for each other (host and guest) they are not available. Not even ARPs. although the MAC macvtap0corresponds to the guest interface, and the entire network of the guest works.
Plus some strange behavior in virsh:

virsh # list
 ID    Имя                         Статус
----------------------------------------------------

virsh # domstate win7
выключен

those. domain list not showing...

Answer 1

This is normal behavior for macvtap and is described in the first Google results. For example, here
A list of all (including disabled) domains is displayed in virsh list --all, and this is also described in the documentation .
