Host-only network with static IP address seems broken #4202

Open dragos-bth opened 2 years ago

dragos-bth commented 2 years ago

I have configured a Ubunt 22.04 Server VM (ARM64) with default settings on UTM 3.2.4 (58) under MacOS Monterey 12.4 (Apple Sillicon). The shared interface was changed to a host-only interface, where the subnet address and host address were specified as 192.168.168.0/24 and 192.168.168.11 (see below full QEMU command).

When starting the VM under UTM I receive the following error message: "qemu-aarch64-softmmu: -netdev vmnet-host,id=net0,net=192.168.168.0/24,host=192.168.168.11,hostname=192.168.168.11: Invalid parameter 'net'

If I change the network to "Shared network" I still receive the same error message. Only after clearing Guest Network and Host Address from the configuration is the VM able to boot without error messages.

The expected behavior was that the VM will assign 192.168.168.11/24 to its primary interface.

Were you ever able to find a workaround?

dragos-bth commented 2 years ago

No, I don't think there is a workaround other than using a shared network, which does not work for my use case.

The problem seems to be that qemu-7.0.0 lacks support for wmnet on MacOS. This is apparently fixed in qemu-7.1 so hopefully the next UTM release will support host-only networking.
