I have created a VM on Hyper-V with 2 Network Adapters.
NAT switch for static ip
External Switch (for access internet)
From my command line I was able to connect to the VM with the Nat Switch IP
but from WSL Bash I was not able to connect with IP NatSwitch, but able to connect with ExternalSwitch IP.
Why?
Unfortunately this is the expected behavior. (As of 29/01/2021)
WSL2 uses Hyper-V Virtual Switch, vEthernet (WSL) virtual network adapter, that is providing internal type Hyper-V network that is only accessible from the VM and the Host. The Hyper-V machine has a different virtual network adapter e.g. vEthernet (Default Switch). If that is set to internal that is a different NAT-ed network (subnet) not connected to the WSL one. It is like the Host having 3 NICs and one cable (Cable 1) going to WSL on a subnet that only exists on that adapter/cable and another cable (Cable2) going to Hyper-V guest with a very different subnet on that NIC.
On the other scenario the Hyper-V guest shares the subnet with the Host machine ("Same subnet as the 3rd cable/NIC.") so it is routed back to the VM. See red labels.
There is a workaround in this GitHub issue using port forwarding to Guest VM from WSL.

I have a server running on my windows machine and a hyper-v ubuntu VM
I am trying to test the frontend from my VM but I want to make requests to windows 10
host, how can I get the host's IP?
Go to Wired Connected -> Wired Settings and just copy the DNS IP
I want to be able to SSH into a VM Guest of Virtualbox where the guests are sharing a NAT Network.
LocalNat Portforwarding (See https://www.pythian.com/blog/test-lab-using-virtualbox-nat-networking/ Set Up Portforwarding) is inconvenient vs. having an IP address on the NAT for the host.
Port forwarding requires me to keep specifying the port, e.g. in scp -P 2222 from-file localhost: and it messes with SSH keys as localhost now has two host identities, my laptop and the VM's ssh-rsa key.
Rather than port-forward, is there not a way of just adding another IP for my Virtualbox host?
Thanks, Martin.
You can set up a host-only network in addition to the NAT network. A host-only network is a local network which can connect to both the host and to individual VMs. The host and the VMs can communicate with each other through it.
Using the virtualbox GUI, go to Virtualbox manager > File > Preferences > Network and set up a host-only network. Enable the DHCP server. You could use these settings:
host adapter address is 192.168.56.1
DHCP server address is 192.168.56.100
Both masks are 255.255.255.0
The server address range is 192.168.56.101-192.168.56.254
This gives you the addresses from ...56.2 through ...56.99 to use as static addresses. You can manually assign them to VM interfaces if you like.
After setting up this network, you should see a virtual interface on your host system with the correct IP address (the one assigned to the adapter).
Now, go to network settings for the VM. Add a new network adapter. Set "attached to" to the "host-only adapter", and the name to the host-only network that you set up earlier.
Start the VM. It should see the host-only adapter in addition to whatever adapters it was using before. If it's a modern operating system, it'll probably query the DHCP server and set up the interface on its own. Alternately, from inside the VM OS, you could manually assign static addresses to these interfaces.
You can assign a host-only adapter to a VM in addition to its existing NAT adapter. In the past I've had a windows VM and an Ubuntu Linux VM set up this way. Both VMs and the host had no trouble communicating with each other as well as the Internet.
I have a windows 7 host, on which I am also running a windows 7 virtual machine, essentially I'm trying to setup buildbot, the host runs the build master while the vmware virtual machine will run the build worker. The virtual machine network adapter is configured to host only. The virtual machine It has an ip address of 192.168.1.12, while the host has an ip address of 192.168.1.92. Both addresses are static IPs there's no DHCP involved
I can ping the host from the virtual machine, and I can ping the virtual machine from the host.
But when I try to get both the build master(host) and the build worker(vm) to communicate, nothing seems to happen. Looking at the twisted log in the vm I can see error messages along the lines of
"TCP connection failed to connect to host on ip 192.168.1.92:8999"
Note the buildbot.tac on the build worker(vm) has the ip address of the host (192.168.1.92) and the port on which to connect 8999
I have tried netstat -ano on both the host and the vm and I cannot see any connection between the two.
I have tried turning off the firewall inside the virtual machine, just in case, but no success there either
Any suggestions.
I am new to esxi.I have installed centos vm on esxi.esxi is connected to network.I have set the static ip to centos.Problem is when i try to ping esxi from the guest vm, its not pinging.I tried google it but i didnt get the info about ip configuration of guestvm(cent os).what should be the proper configuration to connect it to the network
Can you describe you configuration and task more detailed? In general, after ESXi install in Configuration -> Networking you'll see Standard Switch with vmkernel port "Management network" with ESXi IP and portgroup "Vm Network". If you have no VLANs and one subnet, you need to set VLAN ID on both vmkernel and portgroup to "None (0)", and made same subnet/gateway settings on vmkernel and inside guest. At last, you need to set in VM Settings - Hardware -> Network Adapter 1 -> Network Label to "Vm Network". It's difficult to advise more without info.
I have hosted a VM (Red Hat Linux) named test-vm on my Desktop machine (Windows) with a static IP address but I don't have any DNS entry for this static IP address.
Without having an entry in the client's host file, to my wonder the ping test-vm responds. How is this possible? How test-vm is resolved at other machines on our LAN Network without having a DNS entry for test-vm?

I guess you are using vmware client in your windows desktop. In this case, the hostname is associated to your vmware virtual DNS. With a ping of broadcast in your network, your vmware virtual DNS is forwarding the ping to your VM Client.
