* Even i have updated rollback update 4 and 5 that is the latest update for SCVMM 2012 SP1.
Please Help in resolving this issue ..
Thanks you . .
Hi
I am getting this below error while removing one host for SCVMM 2012 SP1 .Please help in resoving this issue .
Error (1700)
The Virtual Machine Manager service on the IN-V-CLDVMM2012 server stopped while this job was running. This may have been caused by a system restart.Hello,
When we use use either Windows RE or a third party image based full system restore into a Guest VM, the data transfer speed is painfully slow. we're talking over an hour for 52GB when it should be around 10 minutes!
here is the setup:
Server 2008 R2 hyper-v
broadcom netextreme ll 1Gbps network adapter - this connects to an iSCSI target which holds the recovery images, the iSCSI target resides on a NAS which has several disks in RAID 0 and also has 1Gbps network adapter. the transfer speed achieved to and from the Host (local disks) and NAS is getting around 100MBps, approx 80-90% of the 1Gbps adapter. this is fairly decent performance for us. the disks in the server and NAS achieve much higher than 160MBps.
second broadcom netextreme ll 1Gbps network adapter which assigned to the virtual switch, and shared with the management adapter - again, transfer speeds using this adapter on the host to the NAS is the same as the other one. the virtual machine's OS VHD file exists on a seperate iSCSI target which is on a seperate physical NAS (performance from host to NAS is fine at around 100MBps)
i offline the iSCSI target so I can attach it to the SCSI controller of the VM guest, i start the guest and perform a recovery, the data transfer speed was around 5MBps regardless of restoring a windows image or a third party image, this is nowhere near what I am expecting.
i enabled flow control on both adapters and the performance has gone up to around 10-15MBps, sometimes spiking at about 20MBps, this is still a long way off what I am expecting.
I believe this has to do with the network adapter on the hyper-v host, there must be a setting which needs adjusting but I am unsure what. if I am looking at transfer speeds to all the locations involved, I am easily getting 80MBps -110MBps depending on what I am transferring to and from various locations, so I am expecting a recovery speed within the VM guest of going a minimum of 80MBps, preferably 100MBps really.
any ideas? many thanks

my Hyper V time leak keep change faster even after manual reset.
May i know why will become like this and any solution for this.
appreciated your help and advice. Thanks.
Hi,
We want to create one virtual environment in hyper-v. We have license for windows server 2012 data center edition. We will install hyper-v role in the server. So, please tell us that the data center license includes the hyper-v license?

So I got two new servers a Dell R620 and a R720 running Hyper-V on Windows 2012 R2 all clients on them are 2012 or 2012 R2.
All NICs are Broadcom NetXtreme, 2 quad port per server, I am currently running 15.6.0.10 drivers with 7.6.15 firmware on the R720 and 16.2.0.4 drivers and 7.8.16 firmware on the R620. No guest NICs are teamed.
In the last 2 weeks I had two guest NICs in hyper-v (with a few days between) on the R620 and 1 on the R720 fail to a point where the NIC cant communicate with the network, getting a 169.x.x.x IP address. I delete the NIC in the Virtual Switch Manager, re-add it and everything is fine again. I don't allow the managing OS to share the network adapter, for the most part, I use 1 NIC per VM.
I recall this happening back with Hyper-V 2008 R2 as well, but generally at the time of a driver update or some sort of change. These Hyper-V hosts have no received any drivers, firmware or Microsoft updates anywhere around the time of these failures.
Any ideas?
Hi there
I installed windows server 2012 r2 as my host windows and again installed windows swrver 2012 r2 on hyper-v in one system .
now when I go to file explorer > netwrok there is no computer name to share file or folder between them
How can join both windows to netwrok place in file explorer to share file and folder
before I try windows 8 as my host and server 2012 r2 as hyper and when I went to file explorer > network there were to pc's there . first windows 8 and second win server 2012
but when both windows are server there isn't and network pc's in network location on file explorer
please help me how can I bring them both server to file explorer > netwrok
Thanks

There is Hyper-V cluster with 2 nodes. Windows Server 2012 R2 is used as operating system.
Trying to live migrate test VM from node 1 to node 2 and get error 21502:
Live migration of 'Virtual Machine test' failed.
'Virtual Machine test' failed to fixup network settings. Verify VM settings and update them as necessary.
VM has Network Adapter connected to Virtual switch. This vSwitch has Private network as connection type.
If I set virtual switch property to "Not connected" in Network Adapter settings of VM I get successful migration.
All VM's that are not connected to any private networks (virtual switches with private network connection type) can be live migrated without any issues.
Is there any official reference related to Hyper-V live migration of VM's that have "private network" connection type?
Hi,
I am looking for the preferred NIC assignments for the following setup:
- 1 NIC with 4 x 1GB ports
- The virtual servers need access to the trusted and DMZ LAN. As the VMs are internet facing, most customer traffic will go to DMZ
- There will be other Hyper-V servers, but fail-over clustering is not activated on them. I will use replica's and would like to be able to do live migrations.
My first idea was to team two ports for trusted, and two ports for DMZ. But when I assigned the virtual switch to the trusted network I lost network and realized that this may not be the best idea. I probably need at least one NIC for the management. New idea is to assign two NICs on trusted: one for management to the trusted network with jumbo frames enabled (for live migrations), one for the virtual switch on the trusted network and then a teamed NIC connected to a DMZ virtual switch.
Is this a better setup? Or would you suggest other assignments.
Hi ,
I configure the replication with compression but the network utilization of the initial replica about 25% of 1Gb/s . , it takes about 11 min for 33GB VHD size
I want To fasten the initial replica what are your recommendation to speed it up?
Q: There are some VMs with different subnets in the Hyper-V host, we want to make the VMs communicate with each other. Then, how to achieve this?
A: To achieve this, we need install and configure RRAS role on the Hyper-V Host, and here is the guide.
Lab Environment
Note: if you use external virtual switches, then you need to create router for different subnet externally.
1. Configure IP address for each virtual switch
Figure 1: IP configuration of Internal virtual switch 1
Figure 2: IP configuration of Internal virtual switch 2
2. Configure IP Address, Gateway for Virtual Machines
If VMs want to access each other, we need to configure gateway for Server2012test1 and Server2012test2.
Figure 3: IP Configuration of Server2012test1
Figure 4: IP Configuration of Server2012test2
3. Install RRAS on the Hyper-V Host
Open server manager and choose Add Roles and Features. Select the role “Remote Access”, then select “Routing” of “Role Services” tab and finish the wizard. (Figure 5, 6 and 7)
Figure 5: Install RRAS-1
Figure 6: Install RRAS-2
Figure 7: Install RRAS-3
4. Configure routing on RRAS
1) Click the “routing and remote access” in “tools” of “server manager” (Figure 8)
Figure 8: Configure routing-1
2) In the pop-up window, Right Click “your hostname”, choose “configure and enable routing and remote access” (Figure 9)
Figure 9: Configure routing-2
3) In the wizard, select “secure connection between two private networks” and click “next”. (Figure 10)
Figure 10: Configure routing-3
4) Then choose “no” in Demand-Dial connections to finish it. (Figure 11)
Figure 11: Configure routing-4
Now, Server2012test1 and Server2012test2 can communicate with each other.
In addition, you can setup a VM and configure RRAS on it.

I have A Windows 2012 (Non R2) Standard edition server with one virtual machine. I could not activate the virtual machine with the same serial number on the server sticker. I get the error that the license is in use. Used slui option 4 and still no effect.
Is there anything else I can try? What is the number for a license specialist so I can activate my machine?
Appreciate any assistance.
Windows 2012 and the new VHDX format are stated to have full support for native 4k sector drives.
However if I create a VHDX file on hyper-v 2012 with native 4k (logical + physical sector sizes set to 4k), a windows 2012 Standard guest OS will not install, it gives the error:
Windows cannot be installed to this disk.
This computer's hardware may not support booting to this disk.
Ensure that the disk controller is enabled in the computer's BIOS menu.
however if I set it to a 512e VHDX where the logical sector size is 512k but the physical is 4k then it works fine.
... is the issue that the IDE controller in hyper-v 2012 doesn't support 4k sector drives?
I have read there is a negative performance impact when using 512e so I was hoping to take full advantage of Windows 2012 and native 4k sector drives.
thanks
My SBS2011 DC is running on a 2012R2 Host that's was a member server
I've run into an issue with replication because I needed to reboot the host and of course the host comes up before the DC so I've removed the host from the domain so it's now a standalone Workgroup box
My trouble is the virtual network adapter won't install on the DC VM, keeps telling me 'Microsoft Virtual Adapter is not configured correctly'
I've unzipped the CAB file from the IC disk and tried to manually install the driver for the adapter but no
I assumed an upgrade of the intergrated components would fix it but it reports the components are up to date.
Help please?
Thanks

when researching a computer chess project I discovered a server that supports 1.5 TB of RAM
the motherboard is a 4 socket job with a lot of RAM slots, all in a 1U box, so they fit 20 in a rack with 35 kW per rack
32 GB DDR3 for servers is about $500 a stick right now, so its expensive but lots of them are sold
Hyper-V can cope with this much server?
I could envision a lot of enterprise ideas with this much RAM on a server.

Hi everyone , this is my first time posting here so please be gentle.
I am looking at building an new 2012 R2 with Hyper V setup , everything has to be HP hardware .
2x HyperV 2012 R2 servers running 20-30 VMs . These will be dual 6 core xeons with 128gb of ram
2x 2012 R2 back end storage servers running SMB 3.0 shares , connected to the front end VM servers with multiple 10gb ethernet connections. Not sure on the hardware requirements for these servers so advice helpful .
2x SAS 6gb external enclosure for each storage server . Probably HP d2600 enclosures
A couple of questions :
What is the best way to achieve high availability and redundancy in this setup ? Should I use replica's or a HV cluster ?
What is the best way to ensure redundancy of the storage back ends ? File share clustering?
Would the performance of the SAS enclosure be fast enough ? What kind of drives would be suitable for this? Would 7.2k SAS drives be enough or would we need faster ? What would be the best raid setup ? Initially there would be 12 drives expanding to 24 .
Would a mix of fast SAS or SSD and SATA be more efficient ?
thanks in advance , any help appreciated
