tested on ubuntu
For the Cloud connection to work, make sure you’ve got a bridge already, in which eth0
is part of. Any bridge will do, it can be xenbr0
or virbr0
, and validate with a VPCS.
Here, when the Cloud connection was eth0
itself, the host was not reachable and strangely enough, it still did relay the traffic across the LAN, as the gateway was responding .o0O
For the NAT connection to work, make sure you’ve got the virbr0
bridge already in da place. See the KVM guide.
dpkg --add-architecture i386 add-apt-repository ppa:gns3/ppa apt install gns3-gui gns3-iou gns3-server non-root YES non-root capture YES
we’ve got an issue with dynamips/amd64, we need the i386 flavor. last available was for eoan (http://ppa.launchpad.net/gns3/ppa/ubuntu/pool/main/d/dynamips/)
dpkg -l | grep dynamips dpkg -r dynamips wget http://ppa.launchpad.net/gns3/ppa/ubuntu/pool/main/d/dynamips/dynamips_0.2.21-1~eoan1_i386.deb dpkg -i dynamips_0.2.21-1~eoan1_i386.deb apt-get -f install
make sure you’re compliant with all the KVM and Libvirt requirements (libvirt group and bridge-utils, for example)
and finally restart your user session for the group permissions to apply or hotfix as follows
newgrp wireshark
systemctl status gns3 systemctl restart gns3 systemctl enable gns3 netstat -lntup | grep 3080
as user
gns3
add the Libvirt bridge in da Cloud
