Hyper V on Server 2008 R2 after using Ghost
Hey all...I have a problem I cannot seem to figure out. We are a training center and it is typical for me to build 1 image (lets just say SQL Server 2012. It is build on Server 2008 r2 and the virtuals are of course Hyper V and are prebuilt. I just have to run the import scripts and import them in. All works great. I clone that machine to my ghost server and deploy it out to lets say 15 other machines. This is the problem....the virtuals run just fine. However, if they try to get on the internet from the HOST machine, it takes FOREVER, if it makes it at all. Im assuming it has to do with the virtual switch using the same MAC address from the original machine it was built on, therefore causing a broadcast storm. But if I go into the Hyper V manager and change the MAC address to a static one and put unique numbers in it, nothing changes. I even tried to enable all protocols on the virtual switch, but still no go. Can you guys please tell me what Im doing wrong and how to correct it! Its a huge problem and as of now my only solution is to import the virtuals one by one on each machine, which takes 3 times as long as just ghosting the machine once.
Thanks for your help on this matter!

Unable to remove virtual D-Disk after removing replication
I am replicating servers from one cluster in one datacenter to a cluster in a second datacenter. One of te servers that I was replicating does no longer need to be replicated. What I did was to stop the replication of that server. Then I removed the server
form the target cluster. Then I removed the server from Hyper-V. I thought that the only thing I needed to do after these steps is to remove the files that are still on the SAN. I was able to remove the C-disk (vhdx file) but I was unable to remove the D-disk.
I don't have permission to delete that file. I am using Windows 2012R2.

Microsoft Network Adapter Multiplex Driver version
On a Windows 2012 R2 server I was looking at the property of Teamed Network adapter and noticed the Microsoft Network Adapter Multiplex Driver version in version 6.3.9600.16384 with Driver Date of 2006-Jun-21. File name NdislmPlatform.sys Is this the latest driver?

VM replication crashes on 10G network
Hi all
We have 2 HP servers (2012 R2 GEN1 VMs) on the same LAN running RAID 6 on a 10G network.
Live migration works perfectly at speeds of around 350M.
Hyper V replication runs a little slower and keeps crashing around the 600GB limit. We can resync again and eventually the replication finishes. Our VMs are 11TB in size.
Microsoft say it is a network issue, but my question is why should the replication fail when live migration doesn't? We have also set the resync option to happen immediately, but it never does.
We have tried this with compression and without, but the result is the same.
Thanks for your comments!

Hyper-v Failover cluster NIC configuration
Hi All,
we have production hyper-v cluster failover setup in windows 2012 R2 with two nodes.
Each node has 4 NICs of 1GB each.
1.Management
2.Cluster Heartbeat
3.Storage or livemigration
4.Production (virtual switch) -- trunk interface with network switch to allow multiple VLANs for virtual machines.
In hyper-v switch manager, we have configured Production NIC for virtual switch as indicated below and do not allow management traffic on this NIC selected.
So in each virtual machine, we are selecting Production virtual switch in NIC properties.
the problem is when I saw in the status of Production NIC (virtual switch NIC) in host, there is very high sent/received traffic.
it is 1GB NIC.
the traffic was around in bytes 5696296292 which shows around 5GB.
how it is affecting virtual machines? what is recommendation here? will addition of one NIC in teaming can solve problem?
thank you

Dynamic Expanding VHDs did not mount after host reboot
Windows 2008 R2 Hyper V.
Rebooted VM host, and none of the dynamically expanding mounted to their guests have the VM host reboot. We then manually mounted the drives, all contained no data, and the guest OS we requesting to initialize the drives for first use.
Has anyone seen this before.
We did install Symantec BU exec client on the host. Gracefully shutdown all the guests, and rebooted host, once up we noted the problems with dynamically expanding disks.
Anyone seen this before?
Thanks

many warnings : prevented from using mac address because it is pinned to port
Hi
I am seeing my system log flooded (several per second) with event 28 warnings such as :
Port 'SWITCHPORT-SM-DB9DCFC7-E98D-438C-8998-CC0D9C14ED2B-1-1' was prevented from using MAC address '00-15-5D-00-B2-05' because it is pinned to port 'A0724966-695B-4552-B'.
Source : VMSMP
The environment is 2 X hyper-v 2008 r2 hosts. both have 4 NICs, 3 nics are connected to virtual switches and management OS is not allowed to share the network adapter, and then 1 NIC is obviously used by the host/mgmt OS and no virtual switch connected to
it. I am seeing the warnings on both hosts.
No load balancing or NIC teaming.
All VM's have their MAC addresses assigned dynamically and I cannot see any conflicting MAC addresses.
The warnings are logged for all or most of the MAC addresses and alternate between different "SWITCHPORT-SM-etc,etc" names.
Performance doesn't seem to be degraded, I've run continuous pings for more than an hour with no packet loss, just a single packet spike every now and then. Network access seems fine, Backup Exec 2012 jobs are succeeding, albeit somewhat slower than what it was.
I don't know when it started, since these warnings have flooded out all else.
At first I thought it had something to do with a VM that I moved from one host to the other, where I copied the VHD accross and then created a new VM and assigned the original IP address to the new virtual NIC in the new VM. I then uninstalled the old hidden NIC and restarted the VM in question, but that didn't stop the warnings.
Any ideas what could be causing this, or any tips on where I should start looking to isolate the cause ?

Integration Service Upgrade of 2012R2 breaks Windows 2012 VM
Hi,
we have setup a new server with Windows 2012 R2 and migrated our VM's over to it.
OS within the VM's are Windows 2008 Server, Windows 7 and Windows 2012.
Everything works fine. Integration Service Update was needed and I could install it on all VM's, except one, that also runs Exchange 2013 on a Windows 2012.
Once I install the Update of the Integration Service, the VM acts weird. It takes about 30 minutes until I could log in. (Probably network problem after the udpate). Once logged in, if I switch to desktop view, the task bar doesn't show items other than the clock, clicking it results in the question, if I want to end a hanging process no matter if I say yes/no no luck. Server Manager opens (very slow), but it doesn't load data (wanted to check nic).
CMD with ipconfig doesn't show a network adapter, just the tunneling-peudo-interface.
Load of the server doesn't show high CPU or Memory consumption, nor high disk i/o. Using Alt/TAB it shows a window called "Immersive Background" (tried to translate to english).
Starting the network manager via
control.exe /name Microsoft.NetworkAndSharingCenter
doesn't open it either. But I can open like Resourcemonitor, Powershell and quite some other programs.
So something is failing here after the update.
Does Exchange and the new Integration Service break each other?
I rolled back VM to an older snapshot and tried the same thing again, same result. On our Replication host, I did a Testfailover, with no network connectivity, everything fine, again, until new Integration service are installed/updated, the host seems broken.
So I have no clue what's happening here or where to start to search. The main problem is, that backups have to be done offline and not online until new integration services are up and running.
Any guess what to try or what breaks the new integration services? Or is it really in conjunction with Exchange?
We didn't upgrade the VM to 2012R2, just the root node.
Thanks

Hyper-V 2012 R2 VMQ live migrate (shared nothing) Blue Screen
Hello,
Have Windows Server 2012 R2 Hyper-V server, fully patched, new install. There are two intel Network cards ant there is configured NIC team of them (Windows NIC teaming). Also there is some "Virtual" NICS with assigned VLAN ID.
If I enable VMQ on these NICS and do shared nothing live migration of VM - host gets BSDO. What can be wrong?

how much Number of virtual processors for VMs
Hi,
there is lots more information about logical processors, cores and CPU and their definitions, on the internet. also here in this forum.
In order to make sure i am not lost on internet, it is better to take experts advice like you.
I have simple question read on:
I have a Hyper-v cluster host with 4 sockets (4 CPU's) with 6 cores each. so total are 24 cores.
I can see in hyper-v host Logical processors are 48. (which may be 1 proc = 12 logical processors, so 4 proc x 12 = 48 logical processors)
now how much virtual processors I can assign to each VM. I know I can assign more logical processor depending on application requirement. and it affects application performance. For each VM, it is showing maximum i can select 48 virtual processors.
is it true I can select any number of virtual processors in each VM? is there any limitation?
is it that if i have 8 VMs if i set virtual processors to 6 then it will occupy all logical processors (48 in my case) and i will not be able to allocate logical processor to new VMs?
is it that if i have 10 VMs and all set to 10 virtual processors?
thank you

Change the Network used by Hyper-V Replica
Hi Everyone,
So I just started setting up Hyper-V Replication between 2 failover clusters and have discovered a potential issue. When the replication occurs the primary cluster is using one of my ISCSI NICs to perform the replication. My ISCSI network at the primary site is a separate VLAN that's routed so we can access the SAN for management purposes. At the time this was setup the SAN did not have a dedicated management port. Since this VLAN can access my Replica Broker IP it's using my ISCSI NIC to do the replication. Is there any way to specify which network Hyper-V Replication should use? If not I guess I can disable the VLAN routing as a work around.
Thanks!

Add-VMNetworkAdapterExtendedAcl and a subnet as a RemoteIPAddress parameter
Hello,
I get some strange results using an Add-VMNetworkAdapterExtendedAcl cmdlet.
If I provide a subnet address as a RemoteIPAddress parameter - the Add-VMNetworkAdapterExtendedAcl cmdlet doesn't work as expected,
-RemoteIPAddress <any subnet address> works exactly as -RemoteIPAddress ANY.
But according to the documentation here http://technet.microsoft.com/en-us/library/dn464289.aspx
and here http://technet.microsoft.com/en-us/library/dn375962.aspx#bkmk_detailed
it's possible to use a subnet address with RemoteIPAddress.
My environment (Steps to reproduce):
1) I have a physical server with a Windows Server 2012 R2 with kb2919355 and hyper-v role installed and a VM with a public IP-address and guest OS Windows Server 2008 R2 SP1.
Hyper-V switch which is used by the VM configured as follows:
PS C:\> Get-VMSwitch External | fl AllowManagementOS
AllowManagementOS : False
No any VMNetworkAdapterAcl or VMNetworkAdapterExtendedAcls configured for the VM.
2) ping <VM IP-address> -t from outside networks works.
3) ping google.com (or something pingable) -t from VM OS works.
4) I run a following command on the hyper-v host:
Add-VMNetworkAdapterExtendedAcl -VMName test -Action Deny -Direction Outbound -Protocol "1" -Weight 11 -RemoteIPAddress 10.0.0.0/24
Both ping commands started to return "Request timed out" at once,
despite the fact that there are no hosts from 10.0.0.0/24 subnet in the test environment.
Here is the VMNetworkAdapterExtendedAclconfig:
ParentAdapter : Microsoft.HyperV.PowerShell.VMNetworkAdapter
Direction : Outbound
Action : Deny
LocalIPAddress : ANY
RemoteIPAddress : 10.0.0.0/24
LocalPort : ANY
RemotePort : ANY
Protocol : 1
Weight : 11
Stateful : False
IdleSessionTimeout : 0
IsolationID : 0
ToRemove : False
5) Running Get-VMNetworkAdapterExtendedAcl -VMName test | Remove-VMNetworkAdapterExtendedAcl restores ping replies.
I guess I can use any valid IPv4 network address instead of 10.0.0.0/24 and I will get the same result (I've already tried 123.0.0.0/8 and so on)
Using a single IP-address instead of subnet works without any problem.
So, is that a bug?

Hyper V Configuration
Hello,
I have purchased a new server with Windows Server 2012 R2 Standard on it. From my understanding, I can run two servers on this one physical server via utilizing Hyper-V. Is this correct? If so, are there any tools or articles that can assist with Virtualizing these two domains on this one physical server?

csr1000v routers depoyed on hyper-v eating up all memory
Hi, I have HP server with 12GB physical memory with WS2012 R2 with hyper-v running.
I am deploying about 4-5 CSR1000v routers which by spec requires creating VM with 4GB fixed minimum memory each. However I can not start more than 2 of them at a time because more than that, it complains there is not enough memory. I also tried to set them to dynamic memory and also tried reducing one of them to 1GB to see if it starts but no avail. I also increased the virtual memory to insane amount of 64GB-128GB using one of the available local hard disk but no help either.
Previously I used vmware esxi on same server and were able to run any number of VMs with no problem. I am pretty sure cumulative memory of the running VMs were more than physically available and i think somehow ESXi manages it.
However I think this is not happening on hyper-v by default, so i am wondering if there is any trick in doing it??
Thanks!

2012 R2 Hyper-V VM Disk 2 has been surprise removed | An error was detected on device \Device\Harddisk2\DR2 during a paging operation
I have been scouring the internet for over a week now, and I cannot figure this one out. Some background... I am retiring an old physical file share server, and I am creating a new 2012 R2 VM on a 2012R2 DataCenter Core Hyper-V host. Creating the VM went without issue. It is configured as follows:
8GB RAM
4 CPU Cores
72GB system drive (C:\)
2TB data drive (D:\)
12GB page file drive (Z:\)
I have about 1.8TB of data to copy over from a physical box, so I am using RoboCopy. I have gotten about 1.5TB of data over, then the new VM's data drive (D:\) disappears and the copy fails. The disk no longer appears in Windows Explorer or diskmgmt.msc. The even log shows many event IDs 153 (The IO operation at logical block address 0x*** for Disk 2 was retried) and event IDs 51 (An error was detected on device \Device\Harddisk2\DR2 during a paging operation, and the last event when the drive disappears is a single Event ID 157 (Disk 2 has been surprise removed).
After racking my head over this for several days, I deleted the VHDX for the 2TB data drive, created a new one, and started the data copy all over... same issue. I completely deleted the VM and all files, reinstalled on new VHDX drives... same issue.
This leads me to think it is an issue with the Hyper-V host, but there are no event IDs pertaining to this, and the other 53VMs are running without issue.
I would SINCERELY appreciate any help with this.
Sorry for huge post, but thank you in advance!
