Hi

We have configured Hyper-V 2012 R2 in cluster with minimum bandwidth in weight mode for the virtual switch. Withe the virtual switch DefaultFlowMinimumBandwidthWeight  is 1. Around 40 VMs are running on the cluster, do we need to configure weight on all virtual adapters (Ref: https://technet.microsoft.com/en-us/library/dn550728.aspx). All VMs are in production with same priority

When we check the Minimum Bandwidth weight with VMs it's empty as following "MinimumBandwidthWeight   : "

Thank You 

Hi

We are building HV 2012 R2 clusters for applications / web servers / DBs etc and looking for best practice on placing VHDX with CSV. All Hyper-V hosts are connected through Fiber Channel to SAN storage. Each VM might have 4-5 vhdx (for OS / Page file / application / DB), if we place each VHDX in each CSV then there requires a lot of LUNs, another option is to create LUN / CSV for each server and place all VHDX there. We failed find a doc on best practice on placing vhdx on CSVs. Also recommendation free space needed on CSVs when we consider backup and initial loading of VMs  

Thank You

I have a lite on 256 gig M2 SSd Stick ASMT 2115.

Where would I get the driver for it so that Windows 10 Recognises it.

Hi!

Best Regards,

Hi,

Our switch has been restarted yesterday due to over heat. After this incident our Hyper-V 2012 R2 host has been restarted automatically with minidunb error. we analyzed the BSOD error using WinDbg, kindly find the details below.

We have configured  NIC teaming with 2 physical 10G port, is the server restart with BSOD because of this, if yes, kindly let me know why its happened and how to prevent the same in future.

WS2012 HV host, WS2012 guests, 2 of which are Remote Desktop Session Hosts with User Profile Disks enabled.

RDSH's with UPD's require hotfix https://support.microsoft.com/en-us/kb/2861935, which excludes UPD mount points when enumerating devices for backup. Without that hotfix, backups of these guests have errors.

This hotfix was not included in the new Integration Components installed with the June 2016 Rollup,https://support.microsoft.com/en-us/kb/3161609.

If I save a copy of the VMGUEST.ISO that's patched with KB2861935 for use with future RDSH's, can I install the rollup and the new IC on the other VMs, but leave the RDSH's at the KB2861935 version? Or does everything need to match across the host and all guests?

I have server 2012 r2, running hyper-v role, i am trying to connect to it by hyper-v manager but error rpc service unavailable, i checked all services and all running good, i uninstalled the anti virus and disabled firewall but still same problem. any suggesting solution??

Hi

On my Hyper-V 2012R2 (all updates installed) I have Windows 10 VM.

There is a problem with VSS Integration Services.

Non-Recoverable Error

The protocol version of the component installed in the virtual machine does not match the version expected by the hosting system

I try to update Integration Services on this Windows 10 but system returned Information that "The computer is already the current version of integration services (10.0.10586.0)."

Due to this  I cannot make VM backup of thise machine using Veeam application. Backup job faild and in Hyper-V Integration log I get:

Hyper-V Volume Shadow Copy Requestor failed to connect to virtual machine 'W10-plwropc304' because the version does not match the version expected by Hyper-V (Virtual machine ID 68D49A55-89BE-403F-8CA7-89ABA1225FCE). Framework version: Negotiated (0.0) - Expected (3.0); Message version: Negotiated (0.0) - Expected (5.0). To fix this problem, you must upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.

How to solve this problem?

Kind Regards Tomasz

Hi

I have a new Dell server with 4 x 1GB NICs. The system also has 4 HDD, each is 2TB (7000RPM) configured in two groups of RAID1 for mirroring. 1 group is for the OS and the other is for data. The data raid group is setup to be accessed only by one VM. 

The problem that i am experiencing is that the copy speed from a shared network drive is 500K maximum. I had configured two of the cards to function as a team for fault tolerance, even then the maximum copy speed does not go above 500k with most copies actually taking place at a speed between 20k and 100k. 

To make things worse while experimenting with the different settings I had reset the NICs to default using "netsh winsock reset" and now I don't see the NICs as being part of the team and they are not available to be readded to a new team.

I had suspected the problem could be because of the RAID card is not the top of the line, but these issues happen with only myself logged on to the server (with only 1 VM running). The same files copied between a Windows XP machine and a windows 10 is 3Mbps. It is still not fast, but way better than the windows 2012. The issue is the same regardless of whether i am copying from the VM or the physical server.

Can any one explain to me what I am doing wrong. First I would like to fix the teaming issue. The individual cards are accessible.

Hi,

I virtualized Windows server 2003 R2 by disk2vhd. On windows 10 I created first generation Virtual Machine and connected vhdx drive.

Windows can only start in safe mode. I uninstalled every program from HP ( was on HP gen 5 ).

In normal mode immadently restart and back to selecting operating system.

I tried this: https://support.microsoft.com/en-us/kb/555996 but nothing change.

Hello,

I want to know if is it possibile to access on a VM running by Hyper-V on Windows Server 2012 R2 using VNC client instead of RDP client.

The reason is because on this VM client (Windows 7 Prof. or higher, it's same) we need to install Check Point VPN-1 SecureClient to connect remotely on other PC client: the problem is that when we are connected, the secure profile, disconnect all active VM network connection. Now we use this VM client on VMWare server and want to migrate (or recreate, it's same) to Hyper-V Manager on Windows Server 2012 R2.

Thanks in advance,

Fabio

Dear All,

Hope are you fine and doing well.

I want to disable taking a checkpoint/snapshot for a specific VM, how can I do that?

Thanks

Hi Guys

I have Hyper V on 2012 R2. I have a virtual machine with ISCSI attached disk. Its configured strictly using ISCSI and NOT as a pass-through. How can I convert this disk to VHDX???

Hi,

We have installed windows 2012 R2 Hyper-V on CISCO UCS blade b200 M4. On top of this Hyper-V, we have created multiple windows 2012 R2 Virtual Machine and trying to allocate the storage LUN directly to this VM through Hyper-V Virtual Fiber Channel. However, when we generate virtual WWN on Hyper-V, it is not visible on both of the storage fabric. out of two address set A and B, only address set A is visible in virtual machine and on storage fabric.

is this expected behavior or we should see both the address set WWP Number in VM and storage end?

Regards,

Hi,

Hi, have created some VMs fine on 2008R2 and 2012 Hyper-V but now onto 2012 R2, am using the Gen 2 VM and hitting install error when booting them from the 2012R2 RTM .ISO (downloaded straight from Technet) loaded into virtual DVD:

I see from http://social.technet.microsoft.com/Forums/windowsserver/en-US/53f901e4-5bd0-4e13-80a2-bca2f57b15e9/hyperv-unable-to-boot-from-cd-or-iso-in-vm-machine?forum=winserverhyperv that Hyper-V seems unable to boot from a synthetic SCSI until guest OS actually installed - so Catch-22! But I can't add an IDE Controller because it's not on the list:

I tried the Integration Services and it seems fine on the Settings (including ticking the only one unticked - Guest Services) although if you need to run them from the DVD, it has the same problem - you can see them loaded (or the Win2012R2 ISO) in the DVD Media but you can't make them run through booting on SCSI!

The physical drives are SATA not SCSI but presumably no matter as Hyper-V runs SCSI virtually, but why does Hyper-V default to SCSI and how do I get the DVD to run off an IDE instead if that is the way to install a base OS from .ISO? Or is there an easier way than all this?

TIA, Phil.

WS2012 HV host, WS2012R2 guest. Have installed KB3161609 v2, including its new VMGUEST.ISO.

I can install the new ICs on the 2012 guests, but on 2012R2, I get "This computer is already running the current version of integration services  (version 6.3.9600.16384)."

Am I supposed to upgrade the IC on 2012R2 guests of a 2012 host? If so, how?

TIA

Hi, i am new on hyper-V and veeam, i have created 2 VM with the different VHD on each VM, when i add hyper-V server on veeam, the 1st VM is easy to add and connected. But the other one is failed to connect to host "invalid namespace" Possible Reasons is invalid credentials and specified host is not a Hyper-V Server.

The problem is, i can easy ping or connecting via Remote Desktop on 2 VM. is there any services or anything must be installed? Please help.

Thank you.

Regards,
