can't force local IP

[UriZafrir]

Hi all I am having the same issue as #33 but the solution offered isn't working for me. this is my vagrantfile: but the vms get the ip 127.0.0.1 when booting, 10.0.2.15 when typing ifconfig. I had to change the ssh port. Can anyone please assist?

Vagrant.configure("2") do |config|
  config.vm.provision "shell", inline: "echo Hello"

  config.vm.define "controlplane" do |cp|
    cp.vm.box = "perk/ubuntu-2204-arm64"
    cp.vm.hostname = "controlplane"
    #cp.vm.network :private_network, type: "dhcp", ip: "192.168.51.10"
    cp.vm.provider "qemu" do |qe|
      qe.memory = "2G"
      qe.ssh_port = "50022"
      qe.extra_netdev_args = "net=192.168.51.0/24,dhcpstart=192.168.51.10"
    end
  end

  config.vm.define "worker1" do |w1|
    w1.vm.box = "perk/ubuntu-2204-arm64"
    w1.vm.hostname = "worker1"
    #w1.vm.network :private_network, type: "dhcp", ip: "192.168.51.11"
    w1.vm.provider "qemu" do |qe|
      qe.memory = "2G"
      qe.ssh_port = "50023"
      qe.extra_netdev_args = "net=192.168.51.0/24,dhcpstart=192.168.51.11"
    end
  end
end

I tried with your config, it works with the correct ip.

You can you ps -ef|grep qemu to confirm that the network setting is in the command line of qemu, for example:

... /opt/homebrew/bin/qemu-system-aarch64 ... -netdev user,id=net0,hostfwd=tcp::50024-:22,net=192.168.51.0/24,dhcpstart=192.168.51.10 -drive if=virtio,format=qcow2 ...

I seem to encounter a similar issue 👀

I am using this example block from the README:

Vagrant.configure("2") do |config|
  config.vm.box = "perk/ubuntu-20.04-arm64" # README uses debian/bullseye64

  config.vm.provider "qemu" do |qe|
    qe.extra_netdev_args = "net=192.168.51.0/24,dhcpstart=192.168.51.10"
  end
end

However if I try to ping or SSH into it, it does not work:

ping and ssh

``` > ping 192.168.51.10 PING 192.168.51.10 (192.168.51.10): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 [...] > ssh -o ConnectTimeout=5 -o ConnectionAttempts=1 vagrant@192.168.51.10 ssh: connect to host 192.168.51.10 port 22: Operation timed out ```

vagrant ssh works fine and ifconfig shows the correct ip address

vagrant ssh and ifconfig

``` > vagrant ssh Welcome to Ubuntu 20.04.5 LTS (GNU/Linux 5.4.0-137-generic aarch64) [...] # inside the VM > ifconfig eth0: flags=4163 mtu 1500 inet 192.168.51.10 netmask 255.255.255.0 broadcast 192.168.51.255 [...] ```

Also the running qemu proccess looks fine to me:

qemu-system proccess

``` # On host system > ps -ef | grep qemu-system /opt/homebrew/bin/qemu-system-aarch64 -machine virt,accel=hvf,highmem=on -cpu host -smp 2 -m 4G -device virtio-net-device,netdev=net0 -netdev user,id=net0,hostfwd=tcp::50022-:22,net=192.168.51.0/24,dhcpstart=192.168.51.10 -drive if=virtio,format=qcow2 [...] ```

System information

Machine: Mac M1 Pro OS: Ventura 13.3 Vagrant version: Vagrant 2.3.4

Happy to provide additional infomation 😃

[ppggff]

This is the expected behavior.

The ip address in the configuration file (192.168.51.10) is the internal address of the virtual machine. It's works like behind a NAT network. The port 22 is mapped as 50022 on the host (qe.ssh_port = "50022"), so vagrant ssh works.

To get more information about network of qemu, https://wiki.qemu.org/Documentation/Networking, we use user network by default.

Currently, this plugin doesn't support complex network config with vagrant gramma, but you can append qemu config to achieve same effect. What's your requirement? Maybe I could add more example or figure out new feature for that.

[benjaminfayaz]

Oh, thank you for clarifying. What I am trying to achieve is making the VM run on a specific IP within my private network so I can access it by connecting to that IP from my host machine. Is that somehow possible?

EDIT: When using the virtualbox provider, I was able to achieve this by setting

config.vm.network "private_network", ip: "192.168.51.10"

However with this provider I discarded this due to the following warning during the startup log:

==> default: Warning! The QEMU provider doesn't support any of the Vagrant
==> default: high-level network configurations (`config.vm.network`). They
==> default: will be silently ignored.

[UriZafrir]

Hi I am also on Mac M1. I am trying to bootstrap a Kubernetes cluster with one control plane and one worker node. @benjaminfayaz is getting the correct ip in the ifconfig command but I am not. could someone kindly explain what I am missing?

this is the output of ps aux | grep qemu. it seems the net=192.168.51.0/24,dhcpstart=192.168.51.10 part is not there for some reason.

[UriZafrir]

As I see from my previous comment for some reason qemu won't accept the arguments for the private IP. Any ideas please?

[ppggff]

@UriZafrir What version of the plugin do you use? And please try a full restart?

[UriZafrir]

@ppggff found I was using 0.19. updated to 0.3.4. now working! thanks so much :))

[UriZafrir]

another question please. As I understand as long as I don't use tap networking or socket I can't make the two communicate (Except port forwarding which I think is not the solution I am looking for) for example this: https://github.com/ppggff/vagrant-qemu/issues/33

So now I am trying to create a TAP network:

Vagrant.configure("2") do |config|
    (2..3).each do |i|
        config.vm.define "vm-#{i}" do |web|
        web.vm.box = "perk/ubuntu-2204-arm64"
        if i==2
            web.vm.hostname = "master-node"  
        end
        if i==3
            web.vm.hostname = "worker1"
        end
        web.vm.network "private_network", type: "dhcp", ip: "192.168.51.#{i}"
        web.vm.provider "qemu" do |qe|
            qe.memory = "2G"
            qe.net_device = "e1000"
            qe.drive_interface = "ide"
            qe.extra_netdev_args = "net=192.168.51.0/24,dhcpstart=192.168.51.#{i}"
        end
    end
end
end

I would appreciate your assistance.

this is the error I am getting:

see #40 for future develop of private network

@ppggff Is there is way to have two network card's configured on the vm.

• eth0: standard with 10.x.x.x series for internet
• eth1: local network of 192.168.x.x for communication within VMs created via vagrant qemu.

Whenever I try to add a network via vagrant file, it overrides the eth0 and configures the 192.168.x.x range.

nodes = [
    { 
        :hostname => 'root',
        :net => '192.168.51.0/24',
        :dhcp => '192.168.51.10',
        :mem => '2G',
        :cpus => '2'
    },
]

Vagrant.configure(2) do |config|
    nodes.each do |node|
        config.vm.define node[:hostname] do |nodeconfig|
            nodeconfig.vm.box_check_update = false
            # nodeconfig.vm.synced_folder '.', '/vagrant', disabled: true
            nodeconfig.vm.synced_folder ".", "/vagrant", type: "smb", smb_host: '192.168.34.10', smb_username: "xxx@xxx", smb_password: "xxxx"
            nodeconfig.vm.box = 'ppggff/centos-7-aarch64-2009-4K'
            nodeconfig.vm.hostname = node[:hostname] + ".example.com"
            # nodeconfig.vm.provision :shell, :path => "bootstrap.sh"
            nodeconfig.vm.provider :qemu do |qe|
                qe.memory = node[:mem]
                qe.smp = "cores=#{node[:cpus]}"
                qe.qe.net_device = "virtio-net-device,netdev=net1"
                qe.extra_netdev_args = "id=net1,net=#{node[:net]},dhcpstart=#{node[:dhcp]}"
            end
        end
    end
end

Also, if you notice the SMB configuration also doesn't work and results in the permission denied error [1].

I think the thread is here for this conversation - https://github.com/ppggff/vagrant-qemu/issues/40

[ppggff]

@smitjainsj yes, you can:

• use extra_qemu_args to add new configs for the second network card
• set net_device to nil to disable the default first network card (if you want)

Some notes about network in qemu:

• the default user mode network doesn't support communication between VMs, their are some info in #30
• there is no easy way to control the order of network cards in the VM's OS, you may need to config the box with one network card first

For the vmnet config #40, I will try to give a workable vagrant config with extra_qemu_args soon.

About the SMB error, please try the vagrant doc https://developer.hashicorp.com/vagrant/docs/synced-folders/smb
