Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

We have 4 Hyper-V VM's and one of them gets the error, "one of the processes returned error code 14101".  I've rebooted and that didn't help.

How do I fix this?
Hi All,

I am currently in the process of building a new hyper v cluster so i can migrate from 2008R2 to 2012R2. On my 2008R2 cluster we have 1 single nic for live migration and 1 nic for the privacy cluster communication, i know i can now team the live migration, i would like to also team the privacy cluster nic so it has hardware redundancy across 2 nics. Would this have any negative impact on the cluster communication?

Thanks in advance

I have been tasked to migrate a Server 2012 R2 box running SCCM 2012 server to a new HyperV cluster\server in a different location.

Roles on this server:
System Center 2012 Configuration Manager
WDS - Windows Deployment Services.

I am planning to shutdown server and use AzCopy to migrate the VHD, power up and set new IP address and update DNS Records.

Im wondering if anyone has any advice on this?. As far as I can tell the SCCM only refers to Hostname\FQDN and no IP addresses exist in the config.

Does any one have any advice, things to check in advance, issues to watch out for during the migration.

Many thanks
Hi Guys

I'm thinking to buy AlienVault SIEM but is there any chance that I will be able to install it on HyperV.
If not could I install this software on Workstation instead on the server ?  

I am interested to buy heuristic network scan and SIEM  from AlienVault  anyone know the price ?


We received our new DL380 Gen9 HPe server, which we installed Windows 2012 R2 Server.  At the time of these installations, we only had one of the four NICs connected to our network and the same NIC when we created our Hyper-V environment.  Now we can add all four NICs to our network/switch.  
> The plan calls to have ONE of the four NICs dedicated to the business of the Server - A property management software application.
> ONE NIC, with possibility of a Dual-NIC teaming, for the Hyper-V Virtual Machine - there should be at total of 8 VMs once we are completed with the hardware to virtual machine migration.

What I need to do is change the current NIC that is being used by the Server functions and Hyper-V to one of the other NICs so that the Hyper-V network traffic and be isolated from the Server's traffic.
> I have done some extensive research and reading and have attempted to make some changes, but I have not been able to find a clear explanation of how to do this, or if it can even  be done.

Any one have a 'Best Practices' or a 'How To' papers on how to do this?

I have attached screen shots of the Hyper-V Networking and ipconfig /all

Hi All
Has anyone deployed this service to a hyper v machine using windows server 2012r2?if so does anyone have any good guides on how this done?
Thank you advance for your support
Many thanks
I have a server 2008 standard with exchange 2010 installed. I am having issues get it to virtualize using the p2v. The other server at the location had no issues when testing it.

Is there some special steps required with a server that has exchange installed. I am trying to move the server to hyper-V vm on a server 2012R2. The VM just sits at a black screen with a blinking white dot when i try to start it up on the Hyper-V.

I have tried to run a repair to see if i can repair the boot record with a server 2008 standard cd and a windows 7 pro cd both tell me it is not the correct operating system to be able to run a repair from.

If there is a better way to do this then p2v open to suggestions.

Thank you
We have a VM (Windows 7 Pro) in out Windows 10 Pro Hyper-V Manager and wanted to install Genymotion in it.

How can we do this?
We've got a 7+ year old Windows 2012 R2 server running Hypver-V.  One of the applications that runs in a Win 2012 R2 guest stores upwards of 15,000 files ranging between 4 and 10kb each in each of 6 folders.  This is on local storage using 7200rpm SAS drives, setup using RAID 10 (hardware RAID).

The application seems to be running relatively slow during nightly maintenance periods when each and every file is read in about 90,000 files (I can't change that process unfortunately).

One thing I noticed in testing is that copying one of the 15,000 file folders to the same disk shows a speed of only about 8MB/s which is pretty terrible.  If I copy a total of four 500MB files, it copies at about 125MB/s, very acceptable given the basis 7200rpm SAS drives being used.  

So the question becomes, any suggestions on how I can increase the read speed for these smaller files?

We are going to setup a Hyper-V machine on a Windows 2012 server. The VM will also be 2012. Is there anything special I need to do to make usb ports available to the VM? I ask this because several of our products use the USB key to activate over the network.
I had this question after viewing Hyper-V for small business, SAS or SSD?.

I'm getting ready to build out the hardware for our next server and would like some input on hardware choices and configuration. I'm planning a Hyper-V setup, and I've read several helpful guides by Lee and Philip.

Usage & background info:
I need to spin up a SQL box asap for our database application. Ideally, I can buy a box and add memory/hdds in a year when we move from SBS2011+premium addon (separate box) to Hyper-V+4 (DC/Exchange/LoB data/SQL). So, in choosing the hardware, I'd like to get enough CPU and a RAID controller to support that. I'll break down the use cases for the immediate and the future.

IMMEDIATE SQL need: It's going to be set up to replicate with a cloud-based server. Having a copy of the DB on the LAN just makes it so much faster. It's a church management suite....probably 8-10GB in size and growing by a couple gigs a year. There q43 10-20 concurrent users, all working through an endpoint client (kiosk check-in app or database front-end app). Right now, the replication is running on SQL Express 2005 (or 2008?), and we'd like to move to SQL 2012/2014.
    - Initial thoughts: lots of memory and SSD-based storage

FUTURE use: We have about 30 users, 20 full-time. 4-5 printers, no faxing through the network (a stand-alone unit to handle the occasional fax). We have …
I was told trunk mode is recommended for ESXi uplink. But how about for the hyper-V? Shall I use trunk mode or access mode for hyper-V virtual switches? Currently my command is:

 spanning-tree portfast
I am running Hyper V as a host.  The server is a Lenovo 340 server.  On the host machine [hyper V] I can set the display resolution at1920 x 1080.  The OS is server 2012 r2.

On both virtual machines, I can only run 1024 x  768 on the local monitor.  the video driver in the virtual machines is the standard Microsoft driver.  I can adjust the resolution to a higher value on the monitor at the server, but it exceeds the boundaries on the monitor so is not freindly to use.  When I remote in, I use a VPN tunnel and usually remote to the host, then choose whichever virtual machine I wish to work on.  From the remote location, I can go to 1920 x 1080, and that is fine for the session.  I must revert back t the smaller screen size if I need to work on site.

Is there a better way to access the virtual machines?

Is there a method to set the virtual machines to 192 x 1080 and have them display properly at the monitor that is connected to the host, and displays the host normally at 192 x 1080
I had this question after viewing Some Hyper-V Hardware and Software Best Practices.

We are looking at a new server to replace our aging SBS2011 box. I'm going Hyper-V, but I really don't know if it's worth going to a cluster based on our budget and use. Maybe 1 live + 1 replica. The boxes we will probably buy have 8-10 hot plug. Does it make sense to go with 3 eSSDs (costs have really come down!) in Raid 5 for the host OS + DC/Exchange/LoB Apps (sql, WSUS, SEPM) VMs and put the LoB data on 5-7 10k-15k SAS? I know the newer RAID controllers support this.
We have a VM running a Windows Server 2008 operating system.  Within this VM, can one activate the Hyper-V and create more Virtual Machines within this Virtual machine?
We did successfully create three virtual switches (TEAM1 - 3) on each of our two 2012 r2 hyper-v hosts last year. (Again we did that last year and we were able to at that time.) Each host still has plenty of physical nic ports. So we teamed up two ports on each host connecting to a DMZ subnet. Then in Hyper-V Manager we used the teamed adapter to create a virtual switch -- only to find we were not able to. The identical error occurred on both hosts. Here is the error: (as attached)

Error applying Virtual Switch Properties changes.
Failed while adding virtual Ethernet switch connections.
External Ethernet adapter "Microsoft Network Adapter Multiplexor Driver #4" is already bound to the Microsoft Virtual Switch protocol.

I did try disabling/re-enabling both physical adapters and teamed adapter, deleting the team and recreating, and also rebooting the host, etc, to no avail. The hosts are in most recent Windows update. If I change the virtual adapter to use other physical adapter, it will let me create a virtual switch without a problem -- just not those adapters I teamed up.
This error is confusing since the TEAM4 is the one I just newly created, and pretty sure has not bound but why it says already bound....
Have been stuck here for hours. Can you shed some light please?
Hi all, I am setting up a new 6 node cluster as pictured below and plan on enabling replication between SAN1 & SAN2 (the SANs are a single Dell equallogic group). The cluster is split between two rooms and I am having trouble figuring out what would happen if one room lost power or a one of switches fail as its quite easy to see a situation where 3 of the nodes either side can still see the SAN due to the replication. Can anyone shed some light on whether this setup looks particularly prone to split brain? Thanks in advance
Can I use server essentials 2012r2 DVD to setup a physical Hyper-V install and then setup server essentials 2012r2 as a VM on Hyper-V?
Hi Friends,

I have this Dell PowerEdge T310 server running server 2012 r2 Hyper v roles.

Guest1: Data server, server 2012 r2
Guest two : Win 7 machine

All of a sudden users started complaing that the file server is extremely slow, I looked at the server and 100 percent high cpu with no apparent cause or processes. Same with Win 7 machine. No applications running. After hours no users logged on but still high CPU usage.

Hyper V host was a bit slow as well but not too hgh cpu.

Checked through dell open manage and no issues with disk or raid. Rebooted entire host - Same issue.

Increased virtual processor in win 7 machine from 1 to 2 to see if that will help but same issue.

I found 1 snap shot of each guest OS which I deleted but still same issue.

How to go about finding the root cause and fixing this issue ?

Thank you in advance.
I have tried to convert a physical server a few times now the Microsoft Virtual machine converter.  All checks of access pass during the wizard.  The login gains access to the physical server, scans with wmi correctly, access to the hyper-v host passes.  The conversion completes converting the disk, fix up disk, copy disk and then fails on provision hyper-v guest with 'Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))'  I have checked dcomcnfg and the login has  remote access, remote launch, and remote activation.  As well as DCOM Config, find "Windows Management Instrumentation", and the user has Remote Launch and Remote Activation.  Does anyone have ideas what the issue may be?  Thanks
I have acquired a client who had a new Hyper-V host and server done. Needless to say the let that guy go because it was way over kill and improperly configured. So with that being said. I have finally gotten the go ahead to redo the Domain. So I have moved all their VM's including the DC to a temp Hyper-v Host. The problem was I was not able to migrate it due to missing drives and tons of errors. Most of the other VM's migrated with no issues. I tried copying all the files and importing which worked on most of the other problem vm's. The DC would not. So I created a new VM with the drives from the DC. It all works except for the login services. I power down the secondary DC and if I try and login to a machine says "No Logon servers Available" even though the DC is up and working well on the file/print side. I ran the DCDIAG and DCDIAG /Fix and below is the output. I am wondering if there is any thing I can do or if there is a way to re promo that server so I can take down the original host without disruption to the domain.

I have a lenovo server running hyper V with two virtual machines [server2 and exch2] installed

There are two 1 TB drives mirrored for the operating systems.  The two mirrored drives are partitioned with 3 partitions  at approximately 300 MB each to allow the operating systems for the hyperV2, server2 and exch2.

There are four two TB drives that are configured raid 10 to give a total of 3723 GB of space which is partitioned at two  1861 MB partitions for a data drive for server2 and exch2 on hyperV2.

The partitioning was done from computer management on HyperV2.

The virtual drives were created in settings in HyperV2 for server2 and exch2.  The operating systems were installed on the respective drives.

In a similar manner, the four terabyte drives were configured as raid 10.  Then in computer management of hyperV2, the disc1[total size of 3812 GB partitioned into a 2836 GB and a 887 GB partition].  The 2836 GB partition is S2DATA.  It is showing as only having 36% free space or that 1807 GB are used [see attachment computer management hyperV2]
The virtual drive DATA(F) was created in the hyper V manager and was given a location to be S2DATA. The actual data on the drive is 280 GB.
It would appear that by initializing the drive from the hyperV2 location and partitioning the drive, then creating a virtual drive from within the Hyper V manager, that I have doubled up on using the space.

How can I fix this?
We have a Windows 10 HyperV VM with a entire installations apps and are trying to transfer that VM to a window server.  Please advice how-to.
We have a server that fails miserably during updates which has a Broadcom NIC. This is not an unknown issue with Server 2012R2 and the havoc placed on the VM's.

1. what Intel NIC do you recommend.
2. any consideration during installation we should be aware of. For example binding in DNS, DHCP, etc.

Thank you.
