I'm learning Azure and I'm trying to connect a load balancer to the virtual machine instances I have created that are using the same resource group and within the same availability set but the target virtual machine options within the dialog are not available. Am I missing something perhaps? This is a free trial account.
Is there something I've missed perhaps?
Many thanks,
Basic VMs are not eligible for load balancing. You need to use Standard VMs.

I created two VMs. I did not created Availability Set for them because I did not know I will need it. I do not want to re-create those VMs, since I needed one month to configure and install everything on them.
Now I created LB but I can see that I can associate it only to one VM or to Availability Set which will contain multiple VMs (which is as I stated not possible because it can be configured only during the creation of VM).
I try to associate LB to VM but I can see that I can select only one VM.
I cannot believe that I cannot select at least two VMs for LB??? Is this really working in this way?? This is really surprising for me and very disappointing.
Please suggest me if there is some quick work around how to associate Load Balancer with same resource group and virtual network to multiple VMs.
Please!
Is there really not any kind of work around for this? I checked this and it was not mentioned how to associate multiple VMs.
Azure load balancer with single VM
You can use a standard load balancer (you would need to attach standard public ips to the vms). The only way to make it work without Availability Set. Thats how it is in Azure, sadly.

I created a Scale Set (using a template) with an existing virtual network.
This existing virtual network has already a Load Balancer (with a public IP) with specific VMs.
Now, I can't connect to the VMs in the scale set, There's no option to add the scale set to the Load Balancer or to add the scale set's VMs to the Load Balancer. Creating a new Load Balancer doesn't help.
It seems that the only option for adding a backend pool is using an availability set or a single VM (which is not in the Scale Set).
Is there any way to solve this? to somehow add the Scale Set to the Load Balancer or to connect to it?
The goal was to create the scale set to be in the existing Load Balancer (in the network with the other VMs), but unfortunately it didn't work.
It is not posible to add vms in different availability sets to the same lb. VMSS has its own availability set (by desing). so this is not possible.

You can work around by creating vm in the network that will act as a load balancer, but that's obviously not a PAAS solution

Balancer (in the network with the other VMs), but unfortunately it

It is not possible and no need. Please refer to this official document. Azure VMSS instances are behind a load balancer. Also VMSS's intance could not add to a existing load balancer.
Now, I can't connect to the VMs in the scale set.
Do you create inbound NAT rules for your instance? Also, you could create a jump VM in the same VNet to login one instance. See this question.
If you could not login your VM from a jump VM, it is not a VMSS issue. You should check your instance. If you don't do any change for your instances. You could create a ticket to Azure to solve this issue.
I am trying to create virtual machine (VM) in Azure using ARM templates. In classical model of IAAS, we can create a virtual machine without virtual network in cloud service. Similar to classical model i don't want to put VM in virtual network.
Does anyone tried to create vm without virtual network in Azure resource manager.
Thanks in advance.
V2Vms, i.e. Resource manager VMs have a dependency on a network card, which has a dependency on a subnet.
A VNet is used to provide DHCP and Security Group services to the VM. Without it a VM couldn't obtain an IP Address.
It is not possible to create an Azure VM without a vnet, in the same way that it was not possible to create a V1Vm without a cloud service.

Can I add existing virtual machine to virtual network?
I have seen this link
http://blogs.msdn.com/b/walterm/archive/2013/05/29/moving-a-virtual-machine-from-one-virtual-network-to-another.aspx
and it asks to unattach disk and delete and then create new virtual machine.
Which is impossible in production environment vm.
Any other way to do it?
No, no other option for time being (2014-09-05).
As already suggested, you may try with opening a support ticket, but I doubt that would also help. Before all, Virtual Networks are associated with Affinity Groups. An absolute requirement is that the VHD for the VM uses storage account in the same Affinity Group as the Virtual Network, as well as the Cloud Service that hosts the VM should be also in the same Affinity Group.
To conclude, you have slight chance to solve the issue with support ticket if your new VM and its VHDs are in the same Affinity Group as the Virtual Network. If they are not (either the VM or the VHDs), then your only option is delete and recreate.
First I've captured image of my Azure windows virtual machine see, then I created two new virtual machines(VM1, VM2) from this captured image. Now I want to do load balancing with these 2 virtual machines see. But the "LOAD-BALANCE TRAFFIC ON AN EXISTING ENDPOINT" option is disabled (I added the endpoint in VM1) also my availability set is not showing under "AVAILABILITY SET" option in VM2.
If I do the same process by creating virtual machine from the Gallery, and follow the steps from here, it worked for me.
Is there any power shell command or other way to load balance?
Please help me.
Thanks

You need both the virtual machines to be under the same cloud service. Only then you get the option to load balance them. There is no way add existing VMs to the same network. there are operations in the Service management API (usable through powershell) to create a new VM. You can use that to create a fresh VM from your existing image and connect it to the same service as your first VM. Then you'llhave the necessary options enabled for load balancing.
