Package: kvm
Version: 84+dfsg-2
Severity: normal
Hello,
Testing kvm84 from experimental (I use libvirt) I have problems with my
bridged network.
With kvm 72+dfsg-5 everything is fine, I can ping host from the guest
and vice-versa.
Just upgrading kvm to version 84 makes it not working:

When I ping the guest from the host here is what tcpdump in the guest show:
