In versions of Windows higher than 7 and Server 2008R2, the Metro interface comes into play. For Windows 8 and Server 2012, start by hovering the mouse over the lower left corner until the Windows Charm bar appears, left click on the charm to open up the Windows Metro Interface. In Server 2012 R2, there is a little less coordination involved. Just simply left click on the Windows icon in the lower left corner:
Once Hyper-V Manager has loaded, if not already connected, you will need to connect to a host. In this example we will connect to our Hyper-V host TGLAB-HV01. To do this, simply click on the Action menu and click Connect to Server:

The Select Computer window will appear, there are two options. The first option, Local Computer, would be selected if Hyper-V Manager was opened up on the Hyper-V host itself and you wanted to connect to it. The second option, Another Computer, allows you to connect remotely to a host on the network. In our example, the host is on the network, so we will click Browse:
If the client that you are using with Hyper-V Manager is not joined to the same domain as the Hyper-V host, there will be issues connecting. There is a very useful PowerShell script, which can be downloaded here, that allows you to enable Hyper-V Manager access between any domain or workgroup-joined systems.
One great up and coming feature of the next release of Windows and Windows Server is that the Hyper-V Manager snap-in will give the option to connect as another user. This will allow Windows 10 and Server 2016 clients to easily connect to Server 2016 Hyper-V hosts regardless of being on the domain or not. Below is a screenshot of what the new window looks like:
For Windows 8 and Windows 8.1 the process will be similar to Windows 7, however the feature to install will be located in a different folder hierarchy in the windows features window. Instead, you will expand Hyper-V and check the box for Hyper-V GUI Management Tools:
If you need to reset the password to your Server 2012 R2 Hyper-v server, check out this guide we have on how to perform a reset. It should take less than 15 minutes: -v/reset-forgotten-hyper-v-admin-password-windows-cd/.
I created 2 vm's, both activated automatically but limited to 180 days (it is displayed on the screen). I would like to type the product key to convert the evaluation license into a permanent license.Problem: The license key used on the server not accepted.
I have two Win2k8R2 SP1 x64 hyper-v VM's
They reside on a dedicated physical server at a hosting company.
The hosting company provided the VHD files that I used to create the VM's years ago.
As the VM's are in production, I would like to download backups of the VHD files (there are no snapshots) and perform in-place upgrades to Server 2012 and then to 2016. Due to the complexity of what's on these VM's, migrating the content to a fresh OS is not an option.
The hosting company no longer supports Hyper-V, so they likely will not provide me with media to do the in-place upgrades. For clarity: The hosting company will allow me to use Hyper-V, but they won't provide support for it.
My goal is to perform the in-place upgrades and then stand up the upgraded VM's on a fresh dedicated Server Datacenter 2016 hypervisor back at the hosting company. As I understand it the hosting company's Datacenter volume license will cover the guest VM's.
I tried performing the 2008 to 2012 upgrade using a Server 2102 R2 Evaluation ISO from Microsoft but it resulted in an error. Apparently a licensed Win2k8R2 VM cannot be upgraded to Win2012R2 using an Evaluation ISO. I don't know if this is true.
My question is: How can I get the Server 2012R2 and 2016 media to perform the in-place upgrades? And what if anything do I need to know about licensing as it pertains to the above scenario?
For each VM I can set the number of "virtual processors". Can someone explain what a "virtual processor" means: a core, a thread, or something else? How much can I allocate if I have 14 cores and 2 vm's? 1 seems much too low: when fetching update, hyperv tells 3% cpu is used but inside vm, 99% cpu is used according to task manager.
I noticed that the IP range of the default switch is changing a lot without my doing. I installed Ubuntu set up static ip and set gateway manually, which worked perfectly. But then after some update the default network switch's ip range changed and so did the ip of my host computer + gateway's ip so nothing worked within Linux. I had to change everything again.
Windows Server 2019 / Hyper-V Server 2019 is ignoring the "Performance options" selection on hosts and using SMB regardless of any other administrative choice. This is using Kerberos authentication.
I originally assumed that I must have a config problem. I blew two hosts away, clean installs of 2019, no configuration scripts. Just the LBFO network config and a a converged fabric network design. Same problem.
Next I assumed it had to be networking. So drop the teaming, drop the config scripts, drop the VLAN configs, drop the LAGs. 1 physical NIC with access to domain controllers for non-migration traffic. Another single physical NIC - on a crossover cable - for live migration. Same problem.
After this, I have tried clean installs with all group policy being blocked from application on the hypervisors. I've tried clean installs with Microsoft Intel NIC drivers and Intel's v23 and v24 release NIC drivers. Same problem. I've tried the June 2019 re-release of Hyper-V Server 2019 and even a direct from DVD install (no language packs etc), so a 100% vanilla source.
Live Migration: Kerberos & Compression
A test VM with a VHDX with a couple of GB of junk data in it to push back and forwards
All configs are verified
Windows Firewall modes are domain/private - and it makes no difference if Windows Firewall is off
Windows Defender is uninstalled and no other software (let alone security software) is installed, period. These are fresh installs
The ONLY live migration network in the Incoming Live Migration networks list is 10.0.1.1/32 on HV1 and 10.0.1.2/32 on HV2
Using Packet Capture on the 10.0.1.0/24 migration LAN there is plenty of chatter to/from TCP 6600. You can see the VMCX configuration state being transmitted in XML over TCP 6600 and lots of successful back and forth activity for 0.35 seconds. Then traffic on TCP 6600 stops.
Traffic now starts up on the non-Migration network, the 192.168.1.0 network - that is NOT in the Migration networks list. A large block transfer occurs. Packet monitoring this connection shows an SMB transfer occurring. This block transfer is of course, the VHDX file.
Re-doing the transfer now uses the correct 10.0.1.0 network. You can clearly see the VMCX transfer over TCP 6600, then a SMB 2.0 session is established using the value from the hosts file between source and destination over 10.0.1.0. An SMB transfer of the VHDX occurs on the forced 10.0.1.0 network before finally the process is concluded via traffic on TCP 6600 (still on the 10.0.1.0 network) and the transfer completes successfully.
Without the Hosts file entries, Hyper-V seems to be using NetBIOS to find the migration target, it can't so it defaults to whatever network it can find a SMB connection on. However, I say again, the 192.168.1.0 network is not in the Live Migration networks list - Hyper-V should be failing the transfer, not unilaterally deciding to "use any available network for live migration". PowerShell on both hosts confirm that this is correctly configured:
....
MaximumStorageMigrations : 2
MaximumVirtualMachineMigrations : 2
UseAnyNetworkForMigration : False
VirtualMachineMigrationAuthenticationType : Kerberos
VirtualMachineMigrationEnabled : True
VirtualMachineMigrationPerformanceOption : Compression
...
Something is causing it to ignore the Compression setting, but only for VHDX transfers. Other VM data is being sent correctly over TCP 6600. As the 10.0.1.0 network isn't registered in DNS, Hyper-V isn't "aware" that it can find the destination host over that link. Of course, in this test I do not want it to use SMB to perform this transfer, so it should not be using SMB in the first place. What I want is migration traffic to occur over a private 9K Jumbo Frame network - as I've always used - and not bother the 1.5K frame management network.
* win updates tries to install KB 4507459, runs until 99% (3 hours, and at 99% after reboot tells in startup blue screen "impossible de terminer les mises jours, annulation des modifications") (means impossible to finish installing updates, rolling back updates). Retried several times, same failure each time. Why why why? How can I see what's wrong?
HyperV production checkpoint creation failing if VSS service is running, host OS is windows server 2016 STD with 2 Windows 2016 STD VMs on it. one of the VMs checkpoint creation is success (production and standard), where as the other is failing, but able to create the standard check point.
My problem is that none of the hyper-v on the FakeInternet can ping another machine. I did set static IPs so they are on the same subnet. Did i miss something ? Tell me if you need further informations, thanks for your help.
Since Windows 8 supports the installation of the Hyper-V feature, it's also possible to activate its management tools.
To do this, open the control panel and click on "Programs: Uninstall a program".
If you want to fully manage your server remotely and not just Hyper-V, you will need Remote Server Administration Tools (RSAT).
These tools are available in the form of a Windows update (KB2693643 in the case of Windows 8) and that obviously varies depending on your version of Windows.
You will probably receive an error.
However, this is completely normal since you have just changed the network configuration of your Hyper-V server.
In addition, the Hyper-V Manager had warned you previously. 152ee80cbc
