[fedora-virt] Connection breaks for my macvtap

[Richa Marwaha]

Hi

I am trying to run some KVM fuzz testing where I have a tool called scapy
running on my host and guest which changes the data in the IP header of the
packages and send it out to the host and vice versa. I have macvtap setup
on my host (have tried both VEPA and Bridge mode).
My ssh connection to my guest breaks down after having send just 22 packets
and also the gnome crashes. I see the following message in the dmesg

dbus[545]: [system] Rejected send message, 2 matched rules;
type="method_return", sender=":1.0" (uid=0 pid=499
comm="/usr/lib/systemd/systemd-logind ") interface="(unset)"
member="(unset)" error name="(unset)" requested_reply="0"
destination=":1.17" (uid=42 pid=658 comm="/usr/bin/gnome-session -f
--debug
")

The connection to the guest restart but wanted to know what makes it
breakdown.
