I'm migrating a kvm virtual machine from an old host (both hardware and OS) to a new one.
For networking, virt-manager proposed me a new option: macvtap. This looked a good alternative to setting up a bridge on eth0.
So now the guest boots just fine, gets an IP from my local network DHCP server, can reach the internet. The guest also sees other machines on the local network, I can ssh them, etc.
The problem is that the host and the guest do not see each other. I cannot reach the guest from the host using the guest IP, neither can I reach the host from the guest using the host IP. No ping, ssh, http, nothing.
Here is the
route -n command from the host:
$ /sbin/route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
(same output from the guest).
I could probably set up a new tun/tap interface dedicated to communication between host and guest but it looks a little bit overkill. Is there a way to make host and guest communicate?
