I'm having an issue bringing a previously working vagrant box up.
When I run the up command with the line box.vm.network "private_network", ip: "10.0.0.10" in it, I get the error:
The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.
Bridged Network Address: '10.0.0.0'
Host-only Network 'en0: Wi-Fi (Wireless)': '10.0.0.0'
But when I change that same line to box.vm.network "private_network", ip: "10.0.1.10" it works fine (change number after 3rd period 1 from 0).
In my VirtualBox Host Network Manager, I've got
vboxnet1 with the IPv4 Address/Mask 10.0.0.1/24 and vboxnet2 with 10.0.1.1/24. Can anyone give me some help as to why I only seem to be able to use the second? I have no other virtual machines running right now.
Has your network configuration changed recently on the host? Maybe a wifi router, LAN adapter, bridge, VPN tunnel, etc is using 10.0.0.x address space. Typing ifconfig in a Terminal window will reveal all your network interfaces and their IP allocations.

I've run into an issue while using Vagrant.
I have to boxes and I've configured them to be part of different virtualbox internal networks (relevant config below):
Dataplane port
vsrx1.vm.network 'private_network', auto_config: false, nic_type: '82540EM', virtualbox__intnet: **"seg1"**
end
Dataplane port
vsrx3.vm.network 'private_network', auto_config: false, nic_type: '82540EM', virtualbox__intnet: **"seg2"**
end
However, the hosts are able to communicate with one another (they have IPs from the same subnet), although they belong to different private networks.
Does anyone know why?
Thanks,
Cristian
From the vagrant book
NAT Requirement As the First Network Interface
With VirtualBox,
Vagrant requires the first network device attached to the virtual
machine to be a NAT device. The NAT device is used for port
forwarding, which is how Vagrant gets SSH access to the virtual
machine.
Therefore, any host-only or bridged networks will be added as
additional network devices and exposed to the virtual machine as
“eth1,” “eth2,” and so on. “eth0” or “en0” is generally always the NAT
device.
It isn’t currently possible to override this requirement, but it is
important to understand that it is in place.
this first network interface is not set from Vagrantfile, if you ssh into the VM and check the network of the VM, you will see this first network interface used by the host to communicate with the VM (so you can ssh)
I'm trying to set up a personal cloud server on a Surface Pro, but I'm running into a networking issue that has me completely stumped.
My setup looks like this: I've installed a Nextcloud server on a VMWare virtual machine that's running Ubuntu 16.04, and I have it configured to use NAT so the virtual machine shares a fixed ip address with the host machine. I've forwarded ports 80, 443, etc. on the host machine's NAT device so requests go to the virtual machine. Additionally I've configured my router to have a static ip address, and I've forwarded all the relevant ports to the Surface Pro on my router.
So the trouble is that I can't connect to my server from my browser. HOWEVER, I am able to ping my server, I can SSH in to both the virtual machine and the host machine from the internet, and I am able to access the server in my browser from any computer that's connected to LAN, no problem.
This all sounds like it could be a firewall issue to me (maybe port 80 is blocked on the host machine for some reason??) but the fact that I have no trouble accessing the server from LAN is confusing the issue, and also deactivating the firewall on the host machine doesn't solve the issue.
Any thoughts?
I solved the problem! It turns out the NAT device was improperly configured to use its own DHCP service rather than using the local DHCP service. Basically it was assigning a LAN IP address 169.254.72.176 to the virtual machine, while everything else was configured to expect that the virtual machine's IP address was fixed at 192.168.34.43.
I configured 2 guest OS (CentOS & Windows10) in virtual box and the base machine running on windows 10. both guest OS are configured with 2 network cards one is on NAT and other one is Bridged. My problem is only one guest machine is taking IP from my org dhcp and other one is not. please suggest. I tried configuring manual IP but, its not pining.
NAT wont take IP address, it will create internal network and communicate via hosts network IP address.
I was given a large Vagrantfile as part of an inherited project and on doing vagrant up, I get the following error:
The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.
I have made sure no other VMs are running by checking output of vagrant global-status.
I am not on VPN and
I have restarted my machine (Mac laptop).
Yet the error persists.
What to do?
I cannot share the large Vagrantfile but still need to get past this error.
My machine is connected to the Internet using Wi-Fi only, no cable connection.
I am also not very familiar with network-debugging commands.
You need to change the IP you assigned to the VM. If the IP collapses with a network range you should change it.
For example, you might be safe using an IP from range 192.0.2.0/24
If the 192.168.0.0/16 range does not work, you can completely switch to one of the following range
10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
Choosing one or the other will depend of the network configuration of your office.
I've been searching around and found no similar issues have been asked.
My desktop (windows 7) is in LAN, has IP (192.168.3.121).
I installed vmware (windows 7), using NAT connection (172.168.174.128). The guest is able to access internet without problem.
In guest, if I "ping 192.168.3.121", this will be ok.
If I "ping 192.168.3.xxx", will also be ok.
If I "ping 192.168.174.2" (DNS), this will be ok.
If I "ping 192.168.174.1", can't ping.
Note my host Vmnet8's ip is indeed 192.168.174.1. Ping from host also doesn't work.
From host:
"ping 192.168.174.128" (guest IP), does not work
"ping 192.168.174.2", does not work
Both host/guest windows are installed without any other "security/defender/firewall" related softwares.
Anywhere can go wrong?
Thanks.
If you configured your vmware VM to run in a virtualized NAT network, then you will not be able to access/ping your VM from the Host, or anywhere else for that matter, without configuring port forwarding for that virtual NAT network.
If you would like to be able to access your VM from your host you can either:
A) Change the mode of the network adapter for the VM to a bridged adapter. This will make the VM act as if it is just another computer on the same network your Desktop is and will be accessible at an IP such as 192.168.3.122
or
B) Add a Host-Only network adapter to the VM. This second NIC will be connected to a network that has no internet access, but is connected to the host and any other VMs on the same host-only network
Also, check the firewall settings to allow inbound ICMP inside the VM.
You mean that you cannot ping to the VMnet8 interface of your physical PC.
Maybe it is not activated.
It should be activated first by issuing the command at the cmd prompt with the admin's privilege.
C:\Windows\system32>netsh interface set interface name="VMware Network Adapter V
Mnet8" admin=ENABLED
I have seen this issue with two different windows 10 machine & two different version of vmware workstation ( 15 & 16).
One way it works is I start the wireshark & under capture options I select on VMWARE8(default for workstation/need to adjust according to your NAT Interface) & than start ping from My Local Machine to NAT IP of the VM .
It takes time but it works. I do not what triggers this .
My initial thought was it's one of the Windows 10 upgrade but with two different version of windows 10 & this old issue resurfaced.
Navigate to "Control Panel\Network and Internet\Network Connections".
Disable and Enable the VMware Network Adapter VMnet8 and try again.
I was having same problem after the latest release of VirtualBox-6.1.6-137129-Win update. "NAT Network" on any of the guest machine was not working. So i downgraded my virtual box version to 6 and works fine with all my VMs but problem remains in Kali Linux.
NAT Network was successful in giving IP to kali machine but Internet was not working. Problem i found was somehow gateway of kali wasn't set. Then i configured both Gateway and DNS manually and it worked for me.
Make sure that you Uncheck the option "Use this Connection only for resources on this network."
Kali manual configuration for IP, DNS and Gateway
