Hyper-V / NVGRE Gateways / SCVMM 2012 R2

I am currently investigating the roll out of network virtualisation using Hyper-V, Windows Server gateway and SCVMM 2012 R2
I have tested deploying a single WSG in a single datacentre and I can get VMs working with Network Virtualisation.
I have a requirement to deploy network virtualisation in multiple datacentres so that I am able to amongst other things live migrate VMs between datacentres with next to no downtime.
My question is what do I need to deploy to make this work?
For example do I need a WSG in each datacentre and if so are they completely independent of one another or are they aware of one another?
I understand that each datacentre will have its own provider address space but I'm assuming the customer VM network will be the same at each datacentre - this would mean the customer VM network gateway IP would be in two locations but does this matter
if the provider addresses are different?
Is there anyone who has experience configuring WSG / NVGRE at multiple sites who could give some useful tips?
Thanks
John. 

Hi Kristian
Thanks for getting back to me.
BTW the NVGRE white paper is excellent so a big thank you!
To answer your points:
Will the PA network be routable - Yes, I'm assuming I would configure at least one routable PA network per Datacentre - I don't really want to be stretching networks across Datacentres?
Will the hosts in the other datacenter be able to reach the hosts in the primary datacenter where the WSG servers are running -
Yes
I have now destroyed my lab environment and this might seem like a stupid question but the PA gateway address is located on my router and not the NVGW?
Forgetting HA for a moment would you recommend deploying a NV Gateway per datacentre or is this over complicating things? For example if I live migrated a NV VM from DC1 to DC2 would it use DC2's NVGW for external access or will it still use
DC1's?
In my head it seems more straight forward to deploy a HA NVGW at one DC which is used by all other DCs and as you suggested use something like Hyper-V Replica. Do you know if this is supported
Many Thanks
John.

  • I can't find failover cluster management after creating hyper-v cluster on SCVMM 2012 R2

    I've created a hyper-v cluster on scvmm 2012 r2 but I can't find the failover cluster manager to move storage resources. all hosts are showing to have hyperv role and failover clustering feature installed. disk Witness in Quorum is good, same as for the
    other CSV lun. Please help me Microsoft. Thank you. 

    The management consoles are not getting installed while building the cluster through SCVMM. However, its not mandatory to have the management tools on the server. You can have it on a different machine with this management tools installed and connect to
    this cluster remotely.

  • Isolated Lab on Hyper-V (Prod) with SCVMM 2012 R2

    Hello,
    I currently would like to make littla test lab on my Hyper-V 2012 R2 with SCVMM 2012 R2 at work.
    Knowing that there is DC in prod on this Hyper-V, I would like to isolate the lab from the prod without loosing internet access.
    I did try with a server gateway but no connectivity and a lot of errors.
    It is so easy to do witout VMM that I can't understand why it is so difficult now.
    Please let me know.
    Ollie

    You should create a new virtual switch of the type "internal" where the VMs can communicate with the hosts through this switch, and vice versa. Then it will be isolated from the production DC.

  • NVGRE Gateway Cluster Problem

    Hello
    We have following setup:
    Management Hyper-V hosts running WAP, SPF and SCVMM 2012 R2 components
    Gateway Hyper-V host: single node gateway hyper-v host, configured as a single node cluster to be able to join extra hardware in the future
    this Hyper-V host runs 2 Windows Server Gateway VMs,configured as a failover cluster.
    The following script is used to deploy these windows server gateway VMs as a high available NVGRE gateway service:
    http://www.hyper-v.nu/archives/mscholman/2015/01/hyper-v-nvgre-gateway-toolkit/
    two tenant Hyper-V hosts running VMs which are using network virtualization
    The setup is completed successfully and when creating a tenant in WAP and creating VM network for this tenant using NAT, the VMs of this tenant are accessible and can access Internet using the HA Gateway cluster.
    The Gateway Hyper-V host and NVGRE Gateway VMs are running in a DMZ zone, in a DMZ Active Directory Domain.
    Management and Tenant Hyper-V hosts, incl all Management VMs, are running in a dedicated internal Active Directory domain.
    Problems start when we failover the Windows Server Gateway service to the other VM node of the NVGRE Gateway cluster. We see in the lookup records on the Gateway Hyper-V host that the MAC address of the gateway record for tenants is updated with the new
    MAC address of the VM node running the gateway service.
    But in SCVMM, apparently, this record is not updated. The tenant hosts still use the old MAC address of the other Gateway VM node.
    When looking in the SCVMM database, we can also see that in the VMNetworkGateway table that the record representing the gateway of the tenant, still points to the MAC address of the PA network adapter of the other node of the NVGRE Gateway cluster, not to the
    new node on which the gateway service is running after initiating a failover.
    On the tenant hyper-v hosts, the lookup record for the gateway also points to the old node as well.
    When manually changing the record in the VMNetworkGateway table to the new MAC address, and refreshing the tenant hosts in SCVMM, all starts working again and the tenant VMs can access the gateway again.
    Anybody else facing this issue? Or is running a NVGRE Gateway cluster on a single Hyper-V node not supported?
    To be complete, the deployed VMs running the gateway service are not configured as HA VMs.
    Regards
    Stijn

    If i understand your post correctly you have a single Hyper-V Host running 2 GW VM's. I think the problem is that when you deploy a HA VM Gateway Cluster it wants to create a Cluster Resource (PA IP Address) on the Hyper-V host as well. So when you run 2
    hyper-v hosts and 2 gw vm's and you move the active role to another host it will move the Provider Address to the other Hyper-V host as well. I believe this is by design. You should ask yourself also the question why running 2 vm's in a cluster on the same
    node ;-)
    I would recommend to use 2 node Hyper-V Host Cluster (This is needed for the HA PA Address, And not necessary for your GW VM's )
    Then run the deployment toolkit again. Now when that's done again, take a close look on how the Active node on the Hyper-V host has the corresponding PA assiogned on that Hyper-V host. Then do a failover, refresh the cluster manager and take notice
    of the PA address that has moved along to the other Hyper-V host that is the active one. It is diffuclt to explain, in a couple of sentences but i hope you have the opportunity to build the 2nd Hyper-V host aswell and create a cluste.
    Side note: if you want to keep the excising VM Gateway cluster. remove all gateways from VM Networks and remove the Gateway service from VMM. Then provision the second Hyper-V Host, Configure Cluster, Live migrate 1 GW VM node to it. Reconfigure
    Shared VHDX for quorum and csv and  then add back the network service again. Don't try to leave it as a network service in VMM and move the VM to another node. It will not work when failover.

  • NVGRE Gateway Security and Firewalls?

    Hi,
    I am setting up a Hyper-v NVGRE gateway on Windows Server 2012 R2. Now from what I have read the gateways have 3 NICs and one interface dedicated to public IP addresses, I haven't been able to find any information about how the gateways are secured.
    Can they be protected behind hardware firewalls?
    Are they already secured at the time of install out of the box?
    Do we have to use and configure the windows firewall on the gateway for protection?
    Any best practice out there, real like experience / examples or some documentation on this subject as I am struggling?
    Many thanks in advance.
    Microsoft Partner

    Hi,
    i have created some blogs on hyper-v.nu about nvgre gateway.
    My recommendation:
    Put the gateway Hyper-V host and GW VM's in a separate domain.
    Connect the GW VM's directly to internet.
    Enable the Windows Firewall. look after the Network Connection Profile as there are different rule sets for Private, Public and Domain rules. Make sure the external interface is marked as public profile. If you use the toolkit i created for GW deployment
    its configured for you.
    if your company policy doesn't allow to directly connect to the internet put firewall in front, but transparently, or create a public subnet behind that firewall so your GW VM's have public ip's.
    Only use inspection on traffic (IDS), don't block it, if you really need to, create a common allow list for regular ports. Otherwise tenants need to open service requests at your helpdesk to open ports if they want to publish application via a NAT
    rule.
    since you put the hosts and GW VM's in a separate domain you managed to separate it from your management domain, what is in my sense the best practice.
    Use 3th party NVGRE vendors like Boudewijn mentioned as BIG IP F5.

  • SCVMM 2012 R2 HyperV host not pulling PA (Provider Address) when running NVGRE enabled VMs

    Hello,
    I have a SCVMM 2012 R2 NVGRE enabled environment that I setup according to Kristian Nese's "Hybrid Cloud with NVGRE" guide. 
    I have a "Compute" host group setup in SCVMM that is using a Failover Cluster of two WS2012R2 servers that have a iSCSI LUN for VM storage. The cluster itself working fine.
    There is a "Gateway" host group that has one server in it being used for the NVGRE Gateway. 
    The problem I am having is that any VMs I deploy on a VM network that has network virtualization enabled on the PA Network cannot access the internet. The NVGRE Gateway can access the internet just fine. The VMs pull PA addresses and CA addresses correctly.
    The NVGRE gateway host pulls a PA address fine. The only thing that I can tell that is not working correctly is that when I run "get-netvirtualizationprovideraddress" on a hyperv host that has VMs that are using a network with virtualzation enabled,
    it doesn't return any output. Also, when I run "get-netvirtualizationlookuprecord" on the NVGRE host, it does not list the two hyperv "Compute" nodes at all. So, as far as I can tell, the two VM host servers are not pulling a Provider Address.
    But, I have read that they are supposed to automatically pull a PA address as soon as a VM using network virtualization is deployed and running.
    I've been working on this for the last week, and I'm at a complete loss. I have no idea where to go from here. Any help would be much appreciated.
    Thanks!

    Also, I have tried to redeploy other test VM networks, VMs, and the PA Network itself and it still doesn't work. 
    Any ideas?

  • Installing SCVMM 2012 r2 in a VM on Hyper-V 2012 and windows failover cluseter

    Hi,
    I am planning to configure scvmm 2012 r2 that will be managing 30 hyper-v host servers, please guide me will it be ok if i install and configure both scvmm 2012 r2 and sql server 2012 on same VM running on Hyper-V Failover Cluster ?
    Regards,

    Hi,
    Like most of the time, there is a lot of possible topology to achieve your design.
    Installing VMM and the database in a virtual machine on the same cluster that it manage is a supported scenario. 
    The first question you have to ask is : What is the availability level i need for my VMM infrastructure ?If
    you shutdown the SCVMM instance for patching, you are not able to deploy new VM from template, and not able to create and manage Virtual Networks. It don't affect existing VM or Virtual Networks. Does this break your SLA ?
    Most of the time, VMM don't need a guest cluster (unless you are a hosting provider with provisionning portal
    available 24/24 7/7).
    The main advice i will give you is :
    Keep it simple as possible !
    Don't build complex infrastructure if you don't need to achieve a very hight level of availability.
    Availability, complexity and management cost have a exponential relation. 
    For large deployment, you can use a dedicated Hyper-V cluster to deploy System Center and infrastructures services (SCVMM, SCOM etc...) But there is nothing wrong in deploying VMM in the same cluster as the VM it manage. The design you have to achieve should
    be thinking in terms of availability and serviceability.
    I don't think that 30 Hyper-V hosts need a dedicated SQL Guest Cluster.
    If you install VMM on one VM and SQL on another, you will not achieve more performances, but your VMM instance
    will be less "portable".
    Cheer.
    Cedric.

  • VLAN trunking on Hyper-V from SCVMM 2012 R2

    hi All, 
    I have a multiple Hyper-V host, each hyper-V host have 2 physical NIC, 1 Physical NIC connected to Management Network, and the other 1 Physical NIC connected to Production LAN.
    We have 5 VLAN ID in Production LAN,
    based on my experience we can set VLANID's on Network Adapter in VM level, and also we can set VLAINID's on Virtual Switch but only for single VLAN not multiple VLAN.
    The question are as following:
    1. Can we set Trunk on Virtual Switch from SCVMM 2012 R2 console? On this article http://technet.microsoft.com/en-us/library/hh848475.aspx, we can set Trunk for VM by using Set-VMNetworkAdapterVlan, not for virtual switch.
    2. In SCVMM, we can create Logical Network put the VLAN and subnet, create Logical Switch, port profile, port classification,  and associate the Logical Switch to Logical Network. Then we need to add the Logical Network to Hyper-V host. is it means
    that the logical switch become Trunk mode?

    Hi Lopez, 
    Ya, just create vswitch without vlanid, then add vlan id on VM network adapter, and config the switch port behind the server. It's just work.
    thanks

    Hi Guillaume Pincon,
    Please first update both server to latest update and turn off the Windows firewall for narrow down this issue then try build the cluster again, one of the cluster create condition is all the servers should have the same software updates (patches) and service
    packs. If all above steps not work please post the second validation error information.

  • BUG? when Using SCVMM 2012 R2 SP1 RU2 to move a vm and change vlan setting,vlan setting on hyper-v was not changed

    1. when i use scvmm 2012 r2 sp1 ru2 to move a vm to another host(with no vlan trunk ) and change vlan 2 to vlan disabled. the network of vm was lost,when i check the network property on hyper-v management console ,i saw the vlan still the original setting,
    but when i check the network propery on scvmm ,the vlan setting shows disabled,then i refresh the vm on scvmm console,the vlan setting shows vlan 2.
    image 1, move a vm and change vlan settings to be disabled.
    image 2. after vm was moved to another host ,the vm vlan settings shows on hyper-v console

  • Hyper-V 2012 VM Placement by SCVMM 2012 SP1

    Hi,
    I'd like to understand the logic behind VM placement in SCVMM 2012 SP1 and a 8 Node Hyper-v 2012 cluster. Each Node has 32GB RAM and each is a completely identical HP DL360.
    Here is the current placement as performed by SCVMM
    Node 1: 1 VM
    Node 2: 2 VM's
    Node 3: 6 VM's
    Node 4: 1 VM
    Node 5: 2 VM's
    Node 6: 7 VM's
    Node 7: 1 VM
    Node 8: 1 VM
    There are 2 x 16GB VM's, the rest of between 2GB and 8GB. Each of the overloaded hosts has a 16GB VM running on it.
    I have a cluster reserve set to 1 Node failure. Why has it decided to favour Node 3 and 6? I appreciate the Maths to work out Node suitability are very complex but this seems rather odd.
    Thanks in advance.

    Hi,
    Please check “Preferred Owners” settings for each clustered resource.
    There are some scenarios to help you understand failover process:
    Scenario 1: If a node or resource fails and the Preferred Owner List has been defined, the Cluster Service fails the Group to the next available node in the Node List. The Node List is composed of the Preferred Owners List followed by the remaining nodes
    arranged by their Node ID. The Node ID is defined when a node is joined to a cluster or if a node is evicted or and re-added.
    Scenario 2A: If a resource fails and the Preferred Owner List is not set, the Group follows a Node List much like it did in Scenario 1. The Node List is built only from the Node ID. Upon a node or resource failure, resources follow a downward path failing
    to the subsequent node in the Node List. When it reaches the last listed node in the Node List, it starts with the first node in the Node List.
    Scenario 2B: If a node fails and the Preferred Owner List is not set for a group on that node, then an available node will be selected randomly for the group to be moved to. This will distribute the groups among the available nodes.
    Scenario 3: If a Cluster administrator manually chooses Move group and selects Best Possible and the Preferred Owner List is configured, the Group will always start at the top of the Node List. As in Scenario 1, the Node List is composed of the Preferred
    Owner List and the installation order.
    Scenario 4: If, as Cluster administrator, you manually choose Move group and you select Best Possible and the Preferred Owner List is not configured, an active node is chosen randomly to host the group. Without the Preferred Owner List configured, it is
    possible that a Group may move to a Node that is already running several other Groups.
    We recommend that you configure the Preferred Owner list on a large node cluster if the load between nodes is significantly different or if the nodes are not homogeneous.

  • Errors Performing V2V Conversions from ESX 5.5 to Hyper-V 2012 R2 using SCVMM 2012 R2

    I've successfully added my vSphere server and 2 ESXi 5.5 hosts to my SCVMM 2012 R2 server.
    I have also added my 2 Hyper-V 2012 R2 hosts as well.
    When I attempt to do a V2V conversion of a VM from 1 of my ESX hosts to Hyper-V, I receive - "Error (2901) The operation did not complete successfully because of a parameter or call sequence that is not valid. The parameter is incorrect."
    When I go into the details of the job in VMM it shows "1.4 Convert VMDK to virtual hard disk - Failed" and "1.4.1 Deploy file (using HTTP) - Failed"
    Any help resolving this would be appreciated.
    Also, I can do V2V conversions using the same ESX and Hyper-V hosts without any issues using Microsoft Virtual Machine Converter 2.0, but my manager wants me to use VMM.
    Thanks!

    Quite honestly, building fresh on the platform and migrating the apps / services is always the best way to go
    PlateSpin was the last product I knew that had a Linux conversion utility.   Even found this:
    http://blogs.technet.com/b/enterprise_admin/archive/2010/04/26/hyper-v-linux-p2v-with-platespin.aspx
    No idea the current status of PlateSpin.  They were the gold standard back in 2008.
    But honestly, it can be painful.  It all depends on the hardware now.
    With Hyper-V the end boot device is IDE - so if the machine now runs on SCSI, the boot loader pointers need to be modified (if you can find a tool to bring the disk forward).
    Now, that said.  Hyper-V can convert a physical disk to VHD.  That is a stealth feature that has been there from the beginning.  I can't recall if it is block by block, or if the file system must be known for the copy to succeed.
    You mount the disk on the Hyper-V Server and create a new VHD from a physical disk.
    The biggest issue with the conversion utilities is that Windows does not know the Linux file systems.  So you need some Linux tool to do it.
    I know that VMware had a converter that handled Linux - but again, you have to manually fixup the hardware in the boot menu.

  • Deploy VMs with SCVMM 2012 R2 with Internet connection

    Hello everyone,
    I am trying to use SCVMM 2012 R2 to create a network that will eventually hold 2 clouds, but for the moment I can't seem to create the network and connect the VMs to the Internet.
    My lab is this (all hosts are in a LAN, 192.168.0.0/24, gateway 192.168.0.1, and ONLY ONE NIC per HOST ):
    1 host DC, DNS, SQL, SCVMM 2012 R2 (IP 192.168.0.8)
    2 hosts with Hyper-V (IP 192.168.0.9 and 192.168.0.10)
    I'm also planning to create some "virtual" networks for clustering and live migration, which will use the same physical NICs as the management network (since I have only one physical NIC per host).
    Could you please give me a quick guide of how to set this up with SCVMM 2012 R2, so that I can take advantage of the new features (network virtualization, logical networks, logical switch) and for the VMs to be able to reach the Internet?!
    Thank you so much.  

    Thanks for the reply.
    My network architecture is exactly like the one described on your paper, with 2 differences:
    1. I only have one host in the Production group and one host in the Gateway group
    2. The first host has one physical NIC, the second host has 2 NICs, one internal and one with an Internet (routable) IP
    After applying the logical switches on the hosts, I lost Internet connectivity on the gateway host (I have no idea why there is no logical Gateway Switch !!!). VMM completed the jobs with no error.
    Any thoughts?
