Hey,

I have been playing around w/ Hyper V, etc, and I added a VM with Windows Server 2012.  I created an Virtual Network Switch (internal).  I am running a domain controller on the VM.  So, the host machine now has 2 LAN connections (1 Internet to my Wifi Router, and 1 Internal (mydomain.local).

It seems like ever since I added this 2nd intranet LAN on the host PC, my public internet browsing has slowed down.  For example, when the network adapter (vEthernet VLAN Internal) is enabled, my browsing to public internet sites (msdn, etc) is slower than when the vEthernet adapter is disabled.

Any ideas what this could be, and how to troubleshoot?

I am again going through learning curve with new server 2012 product line in my LAN. I want to test the Essential 2012 server and SBS 2011.

I have Dell R510 with 64 GB with Windows 2008 available. Lot of hard drive space and up to 6 NIC available. My ISP allows me 6 static IP addresses so not an issue there.

I want to have one external network through the host w2008 (96.x.y.10) logically link to a virtual LAN with one server and test workstation (192.168.10.x) and another full external access (96.x.y.11) with the other LAN (192.168.11.x).

The LANS will have nothing to do with each other, just testing server solutions. If I can get this working I may move my old SBS2008 over to a third connection.

Can anyone point me to a good leraning site or documentation on this? Thanks

Hi,

I have some VM images running on my Windows 8 laptop, I previously had these images running with Oracle VirtualBox (the drives are VHDs) and the internal network connected fine (VM images could talk to one another).

Now that I have moved the images into Hyper-V for Windows 8 and created a new network adapter, no server can talk to one another.

The Images/VHDs I have running are; Active Directory, Sharepoint and Lync.  I had created an internal network using 192.168.xxx.xxx addresses for all the machines.

Here is/are my question(s);

• What is the proper way to configure a Hyper-V Network to allow the images to talk to one another?
• What is the proper way to allow these images to communicate externally with the internet?  I have 1 NIC on my laptop and when HV took over the connection I could no longer access the internet from the host of my laptop.

Thanks - Greg.

Im setting up the following for a client

1 Dell R710

2 Dell 2950's

1 Dell MD3200 w/ 12 7200rpm Disks in RAID 10 and dual iSCSI Modules

1 iSCSI Dedicated Dell 5448 GB 48 Port Network Switch

I plan to cluster all 3 servers and install Hyper-V Clustered on Clustered Storage to a single LUN on the MD3200 (not including Witness LUN)

I would prefer the customer change the models to SAS but that might not be a possibility

I would like to know realistically how many VM's we can run on each server with 2 iSCSI connections to the MD3200 setup in Dynamic Least Queue Depth in MPIO (or suggest a better mode)

Each iSCSI connection will connect to a separate RAID Module on the MD3200 

I know you would like to know what the virtual machines will be doing but lets just assume for now they will be a mix of standard servers, Exchange, AD, DNS, DHCP, SQL etc... just picture a nice mixture of about 30 Virtual Machines with varying disk load, nothing too heavy.

I have 4 MD3200 at my full time day job and 2 are used in 2 node SQL clusters, 1 is used for 2 Linux Nodes running Oracle and the 4th is used in a Clustered VMWare configuration. The difference is all of ours are SAS and we use all 15k drives instead of 7.2k like my current client has. Our ESXi Cluster has 3 servers and 30+ Virtual Machines and barely breaks a sweat, once I add the 4th server I plan to load anoter 20+ VM's and see no issues in the foreseeable future. It also helps that all of our SQL traffic is piped out to two SQL clusters with their own MD3200's so nothing running on our cluster has heavy disk usage.

Now my current client on the other hand will be using iSCSI and Gigabit connections which in my experience can only handle a few virtual machines per GB connection, maybe 5 depending on what they will be doing. I think 10 VM's per server running over 2 iSCSI connections will be pushing it and thats an incredible waste for the R710 which I know I can run all 30 of our virtual machines on one of our R710's with 196GB of ram and the current top of line Xeons. I dont recall what is in my clients R710 but memory can be added and as long as it has dual quads it can easily run 20 virtual machines. 

Well that's all of it. Let me know what you guys think about the iSCSI connections, any real world similar setups and experiences would be very much appreciated.

Hi,

I use HyperV manager on my Win7 laptop to manage varios HyperV host servers.

2 of these have since been changed and no longer exist.

But my HyperV Manager console still shows them down the left hand side with red X in obviously as it cant contact them.

If i hit Remove Server - they go away for that session but just return next time i fire up HVM!

How can i permanently remove old host machines from my HVM console please?

Thanks

I am looking to make the switch.. my questions today are:

1. Is all the HA with Hyper-V still dependent on failover clustering with CSV? I know we now have shared nothing LM but that seems to really only apply to proactive situation and not true HA. I assume this is also true with replicas? 

2. What types of storage are you all using? I assume something iSCSI based? Any vendor recommendations? I love how things are looking with SMB 3.0 and SOFS but that still of course requires a solid underlying shared storage.

3. How are people migrating VMs from VMware? Native tools or something 3rd party like VEEAM? We plan to depoly SCVMM, would that assist? 

I am looking at QNAP and SansDigital currently for Hyper-V 3.0, just curious what others are running and what their experiences are. Thanks!

On my freshly installed Server 2012 systems, I have have two 10Gbit nics. When I do a file copy between these two systems, I get up to 400MB/s, which is reasonable considering these are budget systems. These systems are pretty vanilla, no strange things done & nothing installed other than Mallanox drivers& roles/features/patches.

I have configured Hyper-V to use these nics by making sure the live migration goes over their IP subnet. (settings, live migrations, Use these IP addresses...).

When I do a live migration & start the resource manager to check performance, I see that indeed the traffic goes over the Mellanox Infinion 10Gbit nics, but is amazingly slow; it doesn't even get to 500Mbit/s. Theoretically I can throw out the 10Gbit nics, as 1Gbit/s is not even reached!

Has anyone experienced something similar? Any ideas what might be causing this or how to fix it?

thanks.

I have a brand new server asus rs700-x7/ps4

2 Xeon E-5-2609

32 gig of ram

2 hard drive in miror

when I boot on the installation CD of Microsoft Hyper-V Server 2012

after loading file 

there is a small blue windows logo then I have a sad face with the message:": ( Your PC ran into a problem and need to restart" for half a second and the server restart

and again -again...

Any idea?

All,

I was trying to move my Virtual Environment from Oracle Virtual Box to Hyper-V.  I have run into a stumbling box that I can't seem to get past.  One of my main uses of Virtual Environment is to use it to remote into my Work PC.  I work from home, so this VM I run quite a bit.  To connect to work I use Cisco AnyConnect.  I do want to use multiple monitors(4) to do my work and my current graphics card does not support grouping monitors into a single one(I'm looking at upgrading sometime).

So, here is my challenge, when I use connect, I'm able to connect to my work VPN.  But I have that  tiny Hyper-V window.

When I use Remote Desktop I can make the screen the size I want.  However, I can't connect to my VPN.  The error message is something about it can't connect from a remote desktop.  I have tried setting up two External Switches so that it has 2 connections two my PC.  However, when Cisco AnyConnect takes over, pinging both IPs become unresponsive.

So, how can I use multiple monitors with Hyper-V and get around this limitation?  

For now, I have had to uninstall hyper-v as installing it causes Oracle Virtualbox to not work at all. I am able to get this to work fine with Virtualbox running a Windows 7 environment.  

My OS is Windows 8 Professional

ok so i installed windwos 2012 std server and installed Hyper-V now i want to install guest OS - Windows 2008 R2 Servers so i installed 2 win2k8 R2 vm's and when i goto activiate i use the key thats given on they Server for Win 2012 std and the key doesnt work one of the characters in the key is " N " when i type that in i get error unacceptable character.

anyone know whats going on here? on the key code of server i have Windows Server 2012 Std 2 CPU/VM.

and now i m pulling my hair.

I had Virtual PC when I was using Windows 7. When I upgraded my OS to Windows 8 and I installed Hyper-V. Now when I start my guest(Windows 7) machine it keeps running in loop(starts- stops more like reset).

I tried disabling AVX(intel feature known to cause issues with Hyper V)

My Laptop Details:

Make: Dell XPS L702x

CPU: i7 - 2630QM

RAM: 6GB

Graphic Card: Geforce 555m

I have installed Windows 2012 Hyper-V Server. The guest VM consists of a couple W2012 Servers simulating a Domain. The hardware is a Intel Intel S1200BTLR board (BIOS is up to date), a Xeon E3 1220Lv2 and a Intel I350 dualport NIC. The I350 support SR-IOV as well as the current driver (V. 17.4) does. The virtual switch is configured to support SR-IOV as well as the NIC in the VMs. However Network Status always shows:

Degraded (SR-IOV not operational)

VMQs are working. The command "(Get-VMHost).IovSupportReasons gives:

SR-IOV cannot be sued on this system as the PCI Express hardware does not support Access Control Services (ACS) at any root port. Contact your vendor for further information.

I really would like to get SR-IOV up and running. Does anybody know if the reason given is the "true" reason? Do I have to configure something (VT-x and VT-d is enabled)? 

I also would like to know if someone has gotten SR-IOV successfull running on stock hardware (like different Intel Server Board, for example one for the E5 processors with integrated i350 NIC).

I tried Intels Website to find some more informations regarding "this product is supported" or "this product will be support with the next driver version. But all it gives is some general information about SR-IOV and whitepapers.

Hello All,

I have a small Hyper-V private cloud running on server 2008 R2 server. How can we make a Hyper-v cloud Hybrid with other providers like Azure or Amazon. Is there a way to extend the Hyper-V enabled private cloud to Microsoft Azure cloud and building a connectivity them? so that we share the work load during peak times.

Thanks

Hi,

I have build a 2012 Server with a single NIC (Emergency replacement for another server that died).

I have installed HyperV.

Host server has a fixed IP Address

Guest OS can receive DHCP address but have set it to fixed.

Guest OS can ping all of network. It can access the internet using DNS Service on Host Server.

Host Server, Rest of network, cannot ping Guest Server or see any services on it.

Windows Firewall Switched off.

Plugged into unmanaged switch now (Cisco unit).

Any idea why this simple config won't work? I have added the guest OS as a domain member for example (which worked) but the host server cannot see the guest server at all. If ping is working traffic is obviously going from one to the other even if Ping does not work.

Server is HP MicroServer with Broadcom NIC

It seems to be the virtual switch that is blocking the traffic.

Hi, I have the following setup:

Host system:
Windows Server 2008 R2 x64, Hyper-V installed

Guest system:
Windows Server 2008 R2 x64
One virtual NIC

I want to install OpenVPN on the guest system. To do that, OpenVPN creates its own TAP adapter and requires a network bridge to an internet-facing NIC on the machine. This is what my network connections looks like:

The Network Bridge is just between the Hyper-V virtual "LAN Adapter" and the "OpenVPN Adapter". But with the bridge enabled, I have no network connectivity. That is, if I right-click and view "Status" of the bridge, it shows many packets sent, but zero received. After some experimentation, I've found:

1. With both LAN and OpenVPN adapters added to the bridge, I have no network connectivity.
2. With just the LAN adapter added to the bridge and the OpenVPN adapter disabled, still no network connectivity.
3. If I remove the LAN Adapter from the bridge or if I delete the bridge, the LAN Adapter itself then correctly connects and I have network connectivity.

Does anybody have any idea what's going on?
