In Hyper-V when we create virtual machine we can assign virtual switch to it.
Is it Possible to assign two virtual switch to Hyper-V? If so How?
If I understand correctly then we can create different type of virual switch.
Internal Network
Private Network
External Network.
I have three VM out of this One VM I want to assign External as well as Internal Network switch. So this VM expose to outside
network. Other two VM have only Internal network switch. So it does not expose to outside network.
Let me know your comment on suggestion.
I am using Windows 10 and Hyper-V.
I found it and hope that it will useful to community as well.
In Virtual Switch Manager Create all switch that you required.
After that go to your VM. ( Make sure that VM is not in running state).
In this Go to Settings.
In this Add Hardware and Select Network Adapter.
Select Switch that you have created.
By this way you can multiple network adapter to Virtual Machine in Hyper-V.

I have a Vm from Azure and in that vm I have another vm running in Hyper-v. That vm in Hyper-v is running a Ubuntu Linux (64 bit) guest operating system, with a virtual appliance. When I run it and it is finished booting, I'm given a IP address like this: "https://10.8.40.104/4442". The problem is I'm not able to access it from inside my 1 vm from Azure. I tried pulling up the browser and pasting the address, but nothing. I am quite new at this so its possible the solution is fairly simple.
Anyone have any idea how I can access that static IP address?
To install Hyper-V in Azure Nested Virtualization, you could follow steps in this blog:
There are (7) short steps that need to be completed to provision a
nested virtual machine inside Microsoft Azure:
Create an Azure VM capable of nesting (Windows Server 2016, etc)
Connect to the Azure VM
Install Hyper-V Feature inside the Azure VM
Create a NAT’ed vSwitch for outside connectivity
Create the guest virtual machine
Configure an IP Address on the nested guest virtual machine
Test Connectivity
For allowing connectivity to the nested virtual machine from outside, you need to create a new virtual switch that will be configured for NAT’ed access. The network flow will be like this: outside---host public IP---host private IP---NAT internal switch---Internal gateway---nested VM private IP.
Feel free to let me know if this helps or need further help.
I've just created a "new" virtual machine in Windows Azure. I say "new" because there is a "Virtual Machine (classic)" option.
The "new" virtual machine is not accesible by the "old" https://manage.windowsazure.com, it's only accesible by the "new" https://portal.azure.com
My problem is that I've expent a couple of days configuring the "new" Virtual Machine and now I want to open the port 80... but I don't find the "endpoint" configuration!!
I've been looking for it many hours :S
Any clues?
Azure Resource Managed VMs now use the concept of Network adapters, Virtual Networks and Security Groups to manage ingress, egress from a machine.
A virtual machine has a network adapter attached, the adapter is placed within a subnet within a virtual network. A security group can then be placed against the subnet and / or the network adapter.
The network adapter can optionally have a publically accessible address bound to it. Either dynamically or statically bound (i.e. if you take a fixed address, you will be charged for it for when the machine isn't running)
I'm not entirely sure its possible to create a security group via the portal (at least I couldn't find any option for it when I just (albeit briefly) looked.
However you can use New-AzureNetworkSecurityGroup to create a security group and then attach it to your Nic through the portal and also configure the security policy. Which you get to via -
Virtual machines -> VNMame-> Settings -> Network interfaces -> NicName -> Choose network security group
It is a little more complicated than the previous method, but once you're used to it it is a lot more flexible.
Edited to add
Depending on your config, you might need to a public IP address attaching also - use New-AzurePublicIpAddress
It's all good. The get-help wasn't up to date and optional params are actually needed. Just make sure to use all params
I have a VM which have a network adapter called 'Ethernet'.
When I create an image from this VM, any VM that I create from that image have only one network adapter named 'Ethernet 2'.
How can I force it have the same network adapter name?
Thank you very much for your help!
This is expected behavior. Network adapter would also change if your VM is healed (i.e. the underlying hardware fails and your image is re-instantiated on a new one). This will also happen if you scale the VM (change the VM size). Changing the name of the network adapter also would happen sometimes when you shutdown the VM (from the portal, which would also de-allocate resources).
Even if the above mentioned limitations are fixed (today, or in the future). I would not rely on using specific name for the adapter in my application.
Even with the recently added feature to have multiple NICs, as described here, you cannot influence the name of the NIC which the OS uses:
The interface name must be unique for the VM, but does not represent
the names of the NICs inside the VM.
It is important to know that the settings for the NIC you dictate from your Virtual Network setup (DNS, IP Address, Subnet Mask) are guaranteed to be taken by your VM. So why the need for specific network adapter name. Also, keep in mind that you should never manually change the network settings inside an Azure VM.
I was trying to change the network numbers address of my Virtual machine on Azure to be in same network rang as another Virtual machine on Azure pool, once I click save on network card, it freezes & became not accessible with Remote Desktop or any other way.
Please Help.
NEVER try to manually change the NIC. The NIC is still owned by the Windows Azure fabric and when you manually make changes, the fabric interprets it as an attempt to bypass its network security measure. You should be able to get access to the VM back by removing and re-adding the VM (when you remove it, be sure not to remove its disks then you can re-provision it from those same disks).
If you're trying to adjust network address spaces (subnets?), you may want to look at using an Azure virtual network to help group VMs together. While this still won't guarantee a fixed internal IP address, it will give you a degree of predictability.
In the new portal I created several new VM's.
During deployment I can get an option to create a stand alone machine or connect to another machine.
But whatever choice I make there is no connectivity between the machines.
Is is possible to connect them to the same VMnwetwork/VLAN?
I want to test two servers in a setup in which they communicate with each other.
Yes, you have 2 options here:
Create a Virtual Network
Add the VM in an existing Cloud Service (mainly used for load balancing)
Note that pinging might not work without opening a port on the Windows Firewall (source)
