You’re saying one VM was cloned from the other. I could imagine a DHCP client saving leases to disk (they can have pretty long validity periods), and if the box was assigned the .106 address at any point and then cloned, the cloned machine would probably try to take that address, in other words ARP the address to determine if it’s taken, and if so, fall back to some other thing. I would have expected an APIPA address but 172.x.y.z is not out of the question depending on config.
Also, if your bridge has an interface connected to e.g. another ISP-provided router then it would expose any DHCP server running behind that interface to your VMs, creating a race.










For how long? This isn’t mask ROM, the cartridges will lose their data.
