Microsoft Virtual Server

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Hi Guys,

We recently are going to migrate an old server to a new HP ML350 server installed with 2 SSD drives, 300GB each (RAID1), and 2 SAS Drives, 1 TB each (RAID1), there will be 2 virtual servers under Hyper-v.

if we install Hyper-V server on SSD drive, the free space for virtual servers will be limited, so we will probably install Hyper-v on HDD but place 2 VHD file on SSD. my concern here, is it going to compromise the virtual server performance if we install Hyper-V on HDD?

Thank you in advance!
Hi all. I have a best practice type question. I was recently advised that if I am moving a server payload from physical to virtual, not P2V but just spin up a 2012 virtual machine, install the apps, shut down physical in preference for virtual, that if the physical server has 4 CPUs you should factor a CPU increase in 1.5. So in my example I would produce the virtual box with 6 CPUs. My question is has anyone seen this documented anywhere. The advise comes from an extremely reliable source otherwise I wouldn't be looking into it. Any guidance or URL links verifying this would be much appreciated.
Thank you.
We are selling some clients out of our business and I need to transfer the data associated with the clients to the new owner. I have server 2012 standard edition running on a server and they want to clone it and then I remove the data I'm keeping from that clone. They want to boot the virtual copy and run the server in their office. I want to keep running my server so I was concerned about the licensing. They say they have data center windows 2012 and they can have unlimited clones. Is this true? Can they take a copy of my machine with my standard license and run a copy of it using their license? I always thought these licenses were tied to the hardware, and I didn't think you could simply switch licenses?
We have a tech that said it is not possible create a VM from a copy or duplicating and making act as one because they some sort of virtualization SAS also IAS.  We are not too knowledgeable on virtualization, but what exactly does this person means?
What is the ssafest way to test upgrading a production environment vcenter 5.0 and it's associated ESXi server to version 6.0?

I made a P2V copy of the vcenter machine, however the update requires a domain controller to run. A direct P2V of a production DC is a risky undertaking at best. There is one DC available that is virtual, would it be safe to make a copy of that?

Once I have virtual test machines, would building an isolated test network within the production environment be acceptable? Or better to find a test box someware and use Virtualbox or something?
system is a 2008 r2 sp1 server with 2 virtual servers.  host runs fine.  one virtual is the logon/active directory/dns server other is a virtual server running proprietary software that the users connect to and work on from workstations.  that software has been acting up and running slow so their tech support recommended host server run windows update to install security and performance updates (had not been done in quite a while).  even though program had been running perfectly fine on existing system but i agree updates are a necessary evil in our profession.

windows update would not run kept getting error to which kb947821 system update checker needed to be run.  finished after quite a while and rebooted system.  after this reboot my virtual AD server can not be connected to.

users can not ping it.  host can not ping AD virtual server.  the proprietary virtual server can not ping AD virtual server.  users can ping host and can ping the virtual server with the proprietary software.  host can ping virtual proprietary server as well.  

from within the AD virtual server can not ping host nor other virtual server.  no settings were changed, nothing showing in host event viewer other than there is no domain controller being it cant see it.

so weird that one virtual server completely lost connection and the other is perfectly fine.  not sure where to go to get it back connected therefore the post here.

here is our situation, like many companies we have many deployments of ESXi spread over the company [many singe node ESXi servers at smaller offices]

we are looking for an idea as to how to organize access to all ESXi servers  [for example a central web page / portal that our admins can go to]

any ideas would be appreciated or examples.  thx much
Here is my exact setup notes:

vcenter server - 5.0.0
2 esxi 5.0.0 host servers
12 windows production servers across the 2 hosts

All production servers show as orphaned on both hosts in vcenter server. And when I vsphere into each host there are no VM's listed at all. Yet I could RDP to all 12  windows production servers and they are up and running properly!

I attempted to use this as a solution:

Which explains how to migrate the vm from one host to another in vcenter server. This process was only able to add a new instance of the VM to the other host in inventory and it was in the powered off mode!

This did nothing but complicate things so I was able to migrate the vm back to its orginal host using the same process in vcenter server - this made it show up on the original host so I vsphered into that host and removed the new instance from the hosts inventory and now was back at square one.

I also followed this resolution:

to restart the management agents on each host but it still did not resolve the issue. both hosts servers are still showing NO vm's but yet the VM's are still up and running properly and they can be accessed via RDP.

Is there a non disruptive way to get them to re-register …
I have a customer that has about 8 check scanners for different banks.  Right now the check scanners are connected to certain employee's computers.  The issue we are having is that when we tried to add multiple scanners to one computer, they conflict with each other.  The bank tech support states that we should only have one scanner per computer.   Is there a way we can centralize all check scanners in one location using Hyper-V?  Can we assign a particular USB port to a particular VM?  My first idea was to order 8 Lenovo Tiny computers with a KVM switch but would consider Hyper-V.  Any thoughts?
i have to nodes in a cluster.
node 1 and node 2, they are used as a host to 10 VM's
node 1 has 8 VM's on it, and node 2 has 2 on it.

i looked at the physical memory used on both nodes , i thought it would be the same despite of the above.
one had 7GB available out of the 96GB, and the other had around 80GB availble of the 96GB.

my questions are as follows:

1- if there were really clustered, shouldn't the RAM looks the same on both nodes ?
2- isn't it better to move some VM's to node 2, so they will be balanced 5VM's on each.
3- how to move them ?
Conversion SummaryConversion ErrorHi,
 I tried to convert a physical Windows 10 PC to HyperV (Windows 2012 R2) Server, but ran into a problem.
                                                              Physical PC:                                              HyperV Server
Computer Name/ IP Address:          RTS /                                HyperV /

* both computers are not domain joined

1. Chose "Physical machine conversion".
2.  Under "Select a physical machine for conversion", I entered RTS in the address field and administrator's username and password.
3. I ran [Scan System] and it detected that OS is W10 Pro, Hard drive space ... NIC
4. I chose two volumes: System Reserved 100MB / 32.96MB  and  (C:) 73.99GB / 31.13GB and kept "Dynamic" as VHD Type.
5. Under "Specify the name, processors and memory for the new virtual machine", I entered. "RTSVM" and kept "1" as # of CPU, changed Memory to 2048MB
6. Under "Select a Hyper-V host as the destination for the vm", I entered "HyperV" in the address field. Entered "hyperv\administrator" and password. After "validating credentials ...", it moved to next section "Disk".
7. Under "Specify a path to store the converted virtual hard disks", I entered "\\hyperv\Downloads\ConvertedVM" in the Path field.
8. Under "Select a location on this machine (RTS) with enough free space for the converted virtual hard disks", I entered "E:\Converted" where  the drive letter "E" is …
Greetings!   I running Hyper-V 2012 R2 on a Lenovo SystemX Server.  16GB RAM, Xeon E3-1271 Process, RAID 10 Array.   I'm running Hyper-V Host Role with 2 Virtual Machines.   I'm using the on-board Broadcom NICs teamed for the Host and using a dual port Intel-I350 T2 NIC for the VMs.   VM Queues are disabled on everything and I'm still getting painfully slow network access.  One of the VMs is a DC that replaced an old physical 2003 DC and it took about 12 hours just to prep the forest when adding the ADDS role on the VM DC.   I went to go start file migration and had to stop because it was just too darn slow.     Anyone have any clue as to what may be going on?  Even when I browse to the old 2003 DC/File Server using a UNC path its slow to come up.  If I go to a client PC and browse to it it's normal.
Greetings I have a Hyper-V 2012 R2 server running a Hyper Host and 2 VMs (1 DC and 1 File Server).   I setup the VMs on an external switch and everything was working fine.   I updated the host NICs drivers and the server froze and crashed and came back up.  Since then the domain controller VM is not functioning properly.  I can ping the other VM (the file server) but can't ping anything else.  I recreated the external switch to no avail.  I'm at a loss.  I had just finished migrating from an old 2003 DC to this new VM DC and I'm kind of at a dead-end.  I already demoted the old server (I know, not smart) and now this.   The VMs are running of a 2 NIC team.   The file server VM I can ping external addresses like but of course have no DNS resolution because DNS is not working properly on the domain controller VM.

I am sizing up a new Hyper-V server for a client. This is the first time I have done this so please feel free to treat me like a 3 year old.

I have attached my thoughts, does it look correct or am I way off?


I added 25 gig to an existing virtual drive.  When I select disk management and click on the drive to extend, the "extend volume" is not available.

How do I fix this?

Server is 2008 R2, Hyper-V
Dear Experts,

I have a scenario where in I need to deploy a firewall virtual appliance on HyperV as a Virtual Machine and I need to dedicated a physical port on HyperV host to that VM where the internet from ISP will land directly on the physical port which needs to be dedicated to the VM where Firewall is installed.

Agenda is Firewall will use this Physical port as a WAN port and should get access to all the public ip subnet and this firewall protects two other virtual machines and these VM's draw their internet from this Firewall virtual appliance

I am running System Center and tried to configure a logical network for this using VMM however with no luck as when I try to deploy a VM for firewall its give many errors. I am not sure how to achieve this.

I thought creating a logical network and assigning it to a physical network port on each HyperV host should give access to direct internet and also provide failover should the hardware of a host fail

Can someone please provide some kind of steps to achieve this

Thanks in advance

We have several Windows Server 2008R2 Hyper-V servers using Acronis Backup & Recovery 11 virtual edition.  When the Windows server is restarted, on the bottom right corner of the screen, we see a little red triangular icon with an exclamation mark, it says "Acronis Managed Machine Service is unavailable", while this icon is showing, we cannot start Acronis software.  In time ( 5-15 minutes, sometimes longer), the icon will disappear, and everything works again.  I noted the CPU usage at startup, it is always low.   Our RAID drives are SSD, so speed is not the problem.  All the servers are XEON based with lots of RAM.

What is causing the delay.
Can I have Vmotion and Management traffic on the same Vswitch?
If some one already did so how to fix without major impact?
I am looking to move a VM (the DC) to another drive on the server as I have a feeling there are issues with the drive it is currently sitting on (see my other open questions).

I have seen the whole export/import however given I am running a later version of Server 2012, I have been reading about the new "move" function which seems to move both its items and the actual virtual drive files.

Given the version I am currently running, what is everyone's thoughts? Do I need to do an export/import or will the move function work fine?

Please note: It is the same server and I would like to not be depending on the drive it currently sits on at all until I can work out the issue.

If I was running HyperV on Windows 2008R2, and wanted to move my virtual images (of servers) to another different physical server, with different hardware, how difficult is this?
I am mainly concerned about compatibility of the VM's with the new hardware, or does the virtual drivers installed on each VM make it easy to move them?

I've seen lots of documentation for converting VMs/VMDK/VHDX/whatever to physical, but I need some guidance on how to take either a VMDK or VHDX to provision physical hard drives.
Here's the catch; this needs to be burned onto DVDs because a) we can't move hard drives around, b) we can't import/export USB drives, c) these workstations will be on different networks.

My scenario: I have a Windows 10 reference image in MDT on a 2012 R2 VM in vCenter 5.1 (nested VMs, yay) that I need to be able to image workstations with because we can't be a 100% VDI environment. I have the VM running well as a VMDK in vSphere and as a VHDX in Hyper-V.

Thanks in advance!
I have a legacy application that won't run properly beyond SQL2008R2 SP3. Just laid down a W2012R2 server. Can I run SQL2008R2SP3 on that server or do I need to go the Hyper-V route with a guest 2008R2 O/S?
After power outage VM doesn't boot, gives the following error.

I know Dynamic Memory in Hyper-V is equivalent to memory ballooning in VMWare, but that does not provide me a way to measure ballooning activity on a Hyper-V host. I need the name of the correct performance counter in Windows Performance Monitor that can tell me if virtual machines are suffering because of ballooning.
