The powerconnect 2848 has the following options for load-balance (layer 2, layer 3, and layer 2 and 3)
Microsoft has "Address Hash".
Of course they are using different language to do the same thing. I have yet to find a document that details this configuration. I am assuming I should set the power-connect to Layer 2 and 3, and Microsoft Nic Team to Static, and Address Hash.
Is this correct?
Additionally, is the Hyper-v Port load balancing option switch independent?
I would like wireless NIC support in Hyper-V so that I can experiment, and perhaps deploy, a virtual wireless router. E.g., dd-wrt x86 in a Hyper-V VM that has a virtual wireless NIC bound to a physical wireless NIC in the host computer. This would be an evolution of the existing facilities in Hyper-V under "Settings->Add Hardware->Network Adapter". (Aside: dd-wrt x86 must see a NIC that is Atheros-based, I have been told). What would it take to get this feature implemented?
Whenever I do Windows Updates inside of any VM, I am unable to connect to the VM during the update process. I get prompted for a reboot to do the updates so I do. The machine shows running and I can see the last saved thumbnail when I select the VM in HyperV manager. However, when I click to connect to the VM using Enhanced Session I get stuck at black screen saying Connecting to "VMNAME"...
I tried to connect without Enhanced Session and I get to the gray page showing the time and date. The time being displayed is not correct it seems like that was last thumbnail it saved which is being displayed. This happens to all my VMs when I try to do
an update and I am wondering if this is normal. I assume its probably at the stage of applying updates like when you update client versions of Windows but doesn't show it. I usually wait for some time then I am able to connect to the VM and updates are installed
fine. Is there anything to change this behavior or is something wrong?
I have a Windows 2012 Server with Hyper-V role installed. I created a Private virtual switch named "Private". I have only 3 VM's that are using this switch, but none of them are able to communicate with each other. I have network discovery and file and printer sharing turn on for all network profiles (Private, Guest or Public, Domain). They are all on the same network. Since this switch did not work, I created a new Private virtual switch named TEST. Without restarting any of the VM's I switched all 3 VM's from the "Private" switch to the "TEST" switch. All the VM's are now able to ping each other. If I switch back to the "Private" switch, all the VM's lose communication with each other. Anyone know what's going on?
I tried the Get-VMSwitch and other various cmdlets, but can't find why this is happening.
I have a server running Server 2012 R2 Datacenter, fully patched.
Yesterday and today when trying to apply this month's Windows Updates to some Hyper-V clients, it is very slow. Both Windows 8.1 and Windows 10 clients that had all previous patches are taking several hours to download the updates.
One of the Windows 8.1 clients took from 10:00 to 17:30. We are on 80Mbps broadband and there was no significant other traffic, or loading on the server.
The internal network is 1Gbps and copying a 2GB .iso image to the Windows 10 VM runs at about 60MBps.
I am running Hyper-V Server 2012 R2 (server core) and 3 VMs - Windows Server Essentials 2012 R2, Windows 10, and a Linux VM (Red Hat derivative). This had been working fine for many months.
I recently recofigured the hard drives on my Hyper-V server and then re-installed the 3 VMs. Since doing that I've found that my Hyper-V server hangs any time I try and reboot the system.
As far as I can tell all 3 VMs have shut down as none of them are responding to PINGs. After waiting for quite some time I eventually just power off the physical machine and then reboot.
This is not very convenient for remote management of the server. Plus I am concerned that a hard reboot like this will eventually corrupt something in one of my VMs.
So far I've not been able to locate any solution for this problem. My Hyper-V server has all the available maintenance installed (as well as all 3 VMs having all available maintenance installed).
Thanks for any assistance you can provide.

Hi.
I have problem with create vmswitch on hyper-V on windows 10.
I have novirtualswitches
When i try create new one using hyper-v manager (i try run as normal, and run as administrator), or powershell ( New-VMSwitch -Name "vNIC1" -AllowManagementOS $true -NetAdapterName"Wi-Fi")I getting an error :
New-VMSwitch : Failed while creating virtual Ethernet switch.
Switch create failed, name = '97B3FECD-1405-473A-A1F3-B47EAC2E3C4C', friendly name = 'vNIC355': I
nvalid handle (0x80070006).
I've triedto reinstall network drivers, reinstal hyper-v role, use wire, and wireless NIC, create external, private or internal vswitch. All times i got this error or sometimes i got :
New-VMSwitch : Failed while creating virtual Ethernet switch.
Switch create failed, name = '1EB12E39-3D11-46C2-97BF-D6B504BE83D1', friendly name = 'vNIC1': Illegal operation attempted on a registry key that has been marked for deletion. (0x800703FA).
Ifsomeone isable tohelpme?
We recently built a new server that runs Hyper-V 2012R2 with 2 VMs. the 2 VMS being a DC and a SQL Server 2014. The server has two nics so it made sense to use the built in tools for NIC Teaming. Everything appears to be running great, however clients report connection loss intermittently to the SQL Server (runs a small ERP package), which kicks them off the system.
This was really never an issue on the older server, which has me to believe it's not the core network, but rather the server itself.
The settings for the Team were initially: Active/Active, Dynamic, Switch Independent (Standard options). I tried making the Active/Active team to go into Active/Standy... no luck. I also removed NIC02 from the Team which only left NIC01 in the team... no luck. I then even disabled NIC02...no luck.
I'm wondering if there is a design flaw in the server build or if this is a know problem for NIC teaming in software? I'm really at a loss on this one since it's so intermittent, but happens about every 1 or 2 hours for everyone.
I have performed a few steps below and it seems like the .vhd file is corrupted.
May I know if Microsoft provides any support for this? and what normally is the root cause?
Thank you.
There is a tool that can recover logical problems in the VHD structure?
A friend called me and told me that his VS R2 Enterprise with 4 VMs suffered a power falure and after that, one of the VMs does not startup anymore. The erros is the same as using VHDMOUNT, something similar: "VHD file could not be mounted"
There is a CHKDSK for VHD files?
How to "rebuild" a corrupetd VHD file? How to analyze logical structure of a offline VHD file?
Hello! Have a big issue with my dedicated server.
VM sometimes going down.
Server SuperMicro with Raid SSD + HDD, 128GB Ram, Xeon E2650 v3 2 CPU
https://www.supermicro.com/products/motherboard/xeon/c600/x10drl-i.cfm
2 network adapters
Intel l210 Gigabit
Memory check
This is memory dump :
DUMP_CLASS: 1Need some assistance. I have several VMs where the time is ahead 2 hours. When I go in and manually change the time it will revert back.
I noticed that the Hyper-V Time Synchronization service is stopped, when I start it I get the message that it started and stopped again, so something is broken. Ideas?
I am using Hyper-V for a training class on a Windows 10 Enterprise 10240 build. In one lab, I have a newtwork share setup to copy items from Host to VM and VM to Host since copy an paste doesn't work. BUT... One student was able to copy and paste from host to VM and VM to host without having to use a network share. Another student with the exact same setup was not. why? Although network sharing works, copy and paste would be much better.

Ack. A user is suddenly unable to access his virtual machine. I dig around a bit. I cannot access the machine through Remote Desktop or through the Hyper-V console. And then lo and behold I discover that the machine has no IP address!
To determine that, I ran the following command in Powershell:
get-vm -name xxxxxxxx | select -ExpandProperty networkadapters
Name IsManagementOs VMName SwitchName MacAddress Status IPAddresses
Networkadapter False xxxxxxxxx Virtual Switch blahblah {ok} {}
(Note the empty brackets under IP address.)
So how do I access this machine so that I can fix whatever's up with its IP address?

Hi,
I had users started calling in that they cannot remote to their personal VMs. I checked all the IPs were changed to 169.254.x.x when they are suppose to start with 172.18.x.x.

Hi
I run a clustered Hyper-V setup, with an replica broker setup and is working.
It is setup to use Certificates. We have now added 2 new nodes, and I have created and installed the certificates correct.
When editing settings for the Replication broker, I can select the certificate, but I can't select apply, as the certificate is the same.
I have tried to remove the checkmark, apply, add the checkmark again, but the new nodes still don't show the certificate, and the replication does not work from these nodes.
What have I done wrong?
Regards Lars.
