≪ Previous: Differencing VHD Eating Disk Space

We have a customer that is currently running HyperV on an IBM x3850 M2 server. They would like to purchase a new x3650 M4 server and join them together to act as a single server pooling all of the resources to optimise their environment. This cannot be done on a hardware level for various reasons but can this be done with HyperV on a software layer taking into account that the hardware is different? We are just looking for a yes or no answer on this as previous research has not given us a definitive answer.

Hi there, am Dinesh here;

I have two Server 2008 R2 Hyper-V servers with several guest VM's . When ever i try to connect to Guest VM's through RSAT or Hyper-V Manager remotely, it asks authentication.

The Problem is:

1. Only Hyper-V Host Administrator account has the privilege to access the guest VM's

2. Even though i put the Correct Domain Admins credentials, i was unable to access the VM's and again prompt the authentication dialog box.

How can i allow domain accounts to access Guest VM's on Hyper-V remotely. (Thank you all Very much in advance for helping me).

Best Regards....

I have some queries for SCVMM:-

1) Is this require a separate machine or can be install on my windows serer 2012 RC machine?

2) Is there "exe" available for this , like I saw a combined package of windows serer 2008 with SCVMM?

3) Which SCVMM can work well (compatible) with Windows server 2012 RC (Hyer-V 3.0)

My host is having Windows Server2012 RC , I want to install SCVMM, please let me know from where I can download SCVMM compatible to Windows server 2012 RC.

It would be great help if I can get steps to install this.

install of SBS very fast, and after installing VM tools, extremly fast

I need one Com port for my fax modem on the SBS server.

So I set the com port on the VM to \\.\pipe\com1

Now I have to do the corresponding on the Host server.

I tried to use WINdbg with the code of windbg -b -k com Stick out tongue ipe,port=\\.\pipe\com_1,resets=0 ,

I did not work, which I expected, the problems is I can't find any relevant documentation on how to do this.

It would be extremly helpful if we would have a driver from MS for this, or is there one?

Many thanks

I want to install windows 7 enterprise as my host opp sys, then install windows server 2008 R2Sp1 on to it,

so i can create two virtual machines that will have windows 7 enterprise and windows xp installed .

Do I create one massive partitioned and formated physical drive to hold the entire system platform (the base operating system, server 2008R2Sp1 plus the virtual drives) or allocate as I create each drive from the physical external hard disk space available? How do I get it to boot into the host operating system?

Hi,

is it possible to hide the MAC address of the host NIC? In my environment MAC port security is enabled and when the system shows both MACs (the host's one and the VM's one) then the switch port gets blocked. I want only the VM's MAC to be shown.

Thanks in advance!

Hi,

I converted a server(2003 R2 SP2 terminal server) to a VM through P2V. My host machine is 2008 R2 SP1.

It was successful on the converion but with two warning messages.

Warning(13210) and Warning(13222). they both said that there are problems while trying to install VM intergation servies.

I went back to the VM and the i don't think the VHDs have any problem during the conversion. the only things it missed are drivers( NIC drivers are missed too).

I tried to install intergation service manually, but i got a error 1603.

I did some research, i tried the solution on the following post, but it didnt' work out for me.

≪ Previous: unable to install intergation service with error 1603 after P2V

I have checked some of the previous posts about this and I am still getting some mixed results. I have remote users connecting back to the company through RDP. The RDP server is Win2K8R2_SP1. This is a VM running on a Hyper-V R2 host. The physical server does not have a sound card but after a VoIP rollout I have several users using softphones. The softphones connect via the standard desktop (which has a sound card) but these users will remote in to run several apps that are not VPN or WAN friendly. Right now if these users get a voicemail they receive a copy as a .wav file in their email (Outlook in the RDP session), so the only way to hear these messages is to send the .wav file to an outside mail account (gmail/hotmail/yahoo) or to have a second Outlook session running on the regular desktop (typically using OWA).

I am looking for a virutal sound card that will work on a Server 2008 R2 virtual machine where the host server is running Hyper-V R2

Thanks,

Hi All!

This particular VM is in a HA Cluster, and I've had another guest server BSOD (same error code) on a different Hyper-V host (The different host had the same event log), but in the same HA cluster.

Just wondering if this Event means anything important? Couldn't find anything about it online. Could this message mean the VHD was removed from the virtual server?

Hyper-V Server VLAN Network Configuration

≫ Next: Need help with 2008r2 hyper-v two NICs with two different networks

≪ Previous: Hyper v host physical vs virtual

Hi,

I would like to deploy some new Hyper-V 2008 R2 hosts.

I read that was recommended to have a dedicated network interface for management.
What is exactly the problem to share a nework interface for both VMs and management?

I will use VLAN set on VMs network cards and a CISCO 3750 physical switch.
If I have a dedicated network interface for VMs, I should set it to TRUNK on CISCO switch and set VLAN on VMs.
Now if I share a single network interface for both management & VMs, what is the configuration on hyper-v and CISCO switch to have management and VM trafic on separated VLANs?

In which case set a vlan directly on the host's network card in the "virtual network manager menu"?

For example, If you create a new virtual switch through "virtual network manager" and set it to VLAN X, than you bind your VM to this switch and set the VM to VLAN Y, the physical switch port is trunked, what is the result for both HOST and VM traffic? Does the traffic is segmented on respective vlan?

Thanks a lot for your advice

Regards

Need help with 2008r2 hyper-v two NICs with two different networks

August 7, 2012, 8:15 pm

≫ Next: Hyper-v and very slow network

≪ Previous: Hyper-V Server VLAN Network Configuration

The server I have is a Dell 2900, dual 1 gbps broadcom NICs with the TCP offload feature.

What I am trying to do is use NIC1 as internal network traffic shared with the host OS - Allow management operating system to share this network adapter

NIC2 is an external network - AKA the internet

NIC1 works perfect, host communicates with the other devices on the network and the internet through the default gateway, as do the virtual machines.

NIC2 does not seem to pass traffic to the virtual machines. Static nor DHCP addresses.

Turning on Allow management to share, adds the virtual NIC, but still no traffic, removing the virtual network and giving control back to the host OS, gets an IP on the external network no problem.

I have searched, and most results state the recomended way to use hyper-v is with both NICs on the same network and one dedicated to the host. The other things I have found that seem relivant is to disable the offload, which I did, but no effect, and to update the broadcom drivers, which I did as well, but no change.

Virtual Networks:

Internal Network - Broadcom BCM5708C NetXtreme II GigE (NDIS VBD Client) #49 - Allow Mangement

External Network - Broadcom BCM5708C NetXtreme II GigE (NDIS VBD Client) #52

Internal works great, but I am not getting traffic from the External network.

What should I be looking for to get more infomation on what is going wrong or what further tests can I run?

Thank you very much your time,

Dear all,

I have a big problem with my hyper-v server and network card. I've found a lot of topic around this question but none of them helped me.

I have a Win 2008 R2 Server with only Hyper-V installed. I have 3 NIC , one is reserved to the host management and the others two are reserved for virtual machine .

All NIC are Intel, one is integrated on the Intel motherboard and the others are Intel Gigabit ET Dual port .

Before installing the role of Hyper-V all NIC worked perfectly with speed around 1Gb (file transfer average 90 MB/Sec, of course I have a Gigabit LAN) .

After Hyper-V install, the host system is going very slow and the network file transfer using the dedicated NIC is about ten time slower (9-10MB /sec) . Same problem with all VM off and also if I remove all VM !

I tried all of suggestion found in old post (disabling TCP checksum / offload ...) but nothing happens.

What is really strange is that by removing all network card all the Host operating system seems to improve the speed... but, of course, I can't use my LAN :(

I need help because every night I must make a full backup of Virtual hard disk from the host to a backup server in my lan.

My configuration:

- Server Win 2008 R2 SP1 with Hyper-V and no others role

- 2 Virtual Machine (one Win 2008 R2 and one Win 7 Ultimate)

- NAS Linux (access via SMB with no problem)

- Various Windows 7 Pro client

Thanks in advance to everybody,

After installing and setting up Hyper-V Server 2008 R2 on my testbox, I went about creating a VM to install Windows 7. I downloaded an ISO image for the Enterprise x86 and Home Premium x86 versions. I copied the ISO for the Enterprise version to a folder on the Hyper-V server and attached it to the VM optical drive. However after beginning the install process, I was confronted with this error:

"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now"

I couldn't browse anywhere on the VM to help out with this problem. I looked at the drive controllers setup on the VM and found nothing out of the ordinary. Thinking that something in the Enterprise install might have a problem with a VM, I detached that image and attached the image for the Home Premium ISO. Same problem occured.

Any thoughts?
