Hi,
I'm new to Virtual machines.
Once the snapshots have been deleted and merged in HyperV they free up free up disk space and all other snapshots are now in a single compact VHD, and the performance increases. Does that mean this single snapshot will build up again in the future and cause the system to slow down?
Thank you,

HI guys
I have a windows server 2012 r2 with hyper-v
i have removed the GUI after configuring the server to my needs
i have followed a few guides online to setup so i can remotely manage this server
i can MMC to the server from windows 7 and 8 to everything except for hyper-v which fails to connect on win7 and 8 and 8-1
any one has an idea of what could be done here started to pull my hair out
thanks
I need to modify the Host (NOT the VM's) VMSwitch VLAN settings via Powershell for automation purposes.
In Server 2012 (NOT R2), this can be done via modifying MSVM_VLANEndPointSettingData
However, it seems in Server 2012 R2, that class is gone. I've manually searched through the MSVM classes, and it seems that the Host VMSWitch VLAN settings are stored in MSVM_EthernetSwitchPortVlanSettingData. Unfortunately, I have no way of tying that class to a specific VMSwitch.
Any know how to do this on Server 2012 R2?
Hi,
On school we are making an environment that has the following:
-2 Hyper-V servers running server 2012 datacenter (one server is running virtual in vmware)
-1 AD server (2012 server)
-Openfiler for storage of hosts
We get the following error everytime we want to run the tests on our cluster:
VPD error: failed to get scsi 83h VPD descriptors
We have configured ISCSI with openfiler, the servers are both connected with the target aswell, we can see the disks in disk management. But it seems something is wrong with ISCSI and we have no idea what we are doing wrong.
I saw that for 2008 server there was a hotfix, but there doesn't seem to be one for 2012 server...
I hope someone knows the solution to this problem.
Regards,
Jorik
I have a 3 node Server 2012R2 Hyper-V failover cluster with 18 guests. Today, I migrated a guest from VMWare using my normal method to one of the nodes in the cluster. Upon completion I added a role to the cluster, the guest appeared in the list of available Virtual Machines and completed successfully. However, I cannot locate the guest on the list of roles within the cluster.
If I connect to the individual node that I know the guest is on, using Hyper-V Manager, I can see the guest, but Failover Cluster Manager refuses to see it.
I have tried this on several workstations, no success.
Any ideas? I have used this same technique for all of the hosted guests without issue until now.
Thanks

Hi,
I'm trying to run the HyperV replica Capacity planner against the HyperV Cluster on the production environment. The cluster consists of 5 Windows 2012 Datacenter hyperV hosts. I downloaded the capacity planner from the following URL.
http://www.microsoft.com/en-au/download/details.aspx?id=39057
Execute it on the SCVMM server (SCVMM 2012 R2 on Windows 2012 R2). Took the default value for Duration for Metric (30 Minutes) and specified the HyperV replica Broker name for the Primary site details. Skipped
the replica site details. However, it doesn't go beyond the following screen. Kept it running for 8 hours with n luck
If I click next i get the following screen,
How can I troubleshoot this issue?
Anyone have any idea what causes this message and how I can go about resolving it? I have two hyper-v servers one gets literally thousands of these warnings every day from pretty much all users while the other gets absolutely none so I assume it is a configuration issue but I have no idea what configuration it could be.

Hello, I have a Windows server 2008 on which I have setup a linux machine as a Hyper-v guest to use as a PBX machine. I need to install a WAN PIPE USB FXO card which is attached as a USB device. I've read some of the posts about pass through disks, but the device is not getting listed in the disk management because its not basically a disk, its more like a driver.Please help asap.
Thank you

I have Server01 & SAN01 connected via ISCSI and 10 Virtual Machines running via Hyper-V
I have Server02 & SAN02 connected via ISCSI and 8 Virtual Machines running via Hyper-V
If I do any type of exports or disc expansions related to a Hyper-V machine the system in question becomes so slow that it almost comes to a stand still.
What could be causing the issue ?
I have a four node cluster running W2012 Datacenter edition on each. All systems have Emulex HBA compatible with Hyper-V and Virtual SAN technology. The hosts are connected to a Brocade SAN Switch with NPIV Enabled. I've created a Virtual SAN on each host. The vSAN is connected to 2 physical HBA. Each HBA is connected to a different physical SAN Switch.
I have some questions about the best practice of the whole system.
1. Do I have to create a vSAN per physical HBA ? Or create one vSAN that include 2 HBA ?
2. Add 2 virtual HBA per VM to have fault tolerance ? Or one virtual HBA that is connected to a vSAN with 2 HBAs ?
3. Do I have to create a virtual port for each VM on the HBA Gui (OCManager) ?
Any best pratice or advice ?
Thanks
Hi,
I have windows 2012 r2 intalled in my laptop (has Hyper-V role installed) and I want to setup a couple of VMs for lab purposes. The VMs will have AD and some of them I want to configured them as clusters for demonstration. I try to use the "Enable virtual hard disk sharing" but I get an error saying that the storage is not supported.
Does anyone has a link or tutorial how to configure this?
PS: I have a clean SSD drive dedicated for the VMs in the laptop.
Thank you.
I'm trying to enable Hyper-V Replication from a 2012 Hyper-V core to a 2012 R2 Hyper-V core. This is going across different domains through a WAN connection. I created and successfully enabled certificates on both servers.
Disabled windows firewall on both servers with "Set-NetFirewallProfile -Profile Domain,Private,Public -Enabled False". Replica server is configured with a static public IP. I can establish a connection on 443 from primary server to replica server and view the connection with netstat.
However, I get the "Could not get configuration details of the specified server" from the replication wizard. If I continue through the wizard I eventually end up withEnabling replication failed. Connection with the server was terminated abnormally (0x00002EFE). It fails to establish a connect with the replication server.
The odd thing is that if I run netstat on the primary server during the replication wizard I see no traffic leaving the primary server. Nor do I see traffic leaving the Hyper-V manager computer, which happens to be a vm on the primary server. I do however
see traffic between manager computer and primary server during the replication wizard process.
It looks like the primary server never attempts to reach the replication server.
I checked the security logs of primary server and see 4634 Logoff,5058 Other System Events, and 5061 System Integrity entries. There are also 4776, 4624, and 4672 entries. Administrative Events display29310 and 32000 errors from Hyper-V-VMMS.
I'm stuck. I'm tempted to take the replica server and connect it to the same LAN as the primary server and live migrate (shared nothing) the VMs so that I can have both hosts on 2012 R2. But this may not be a solution.
Can anyone clue me in to what I'm missing??

My home network crashes every time I try to start up a virtual machine in Hyper-V and also when I'm doing configuration of the network adaptors. Since my Television is IP based it also crashes at the same time. The tech support for my internet suggested that the Virtual machine in HyperV was "crashing the DNS pool" but I have no clue what that means. Does anyone know of what might cause this or possibly how to fix it?
Thanks

I am having some problems performing a Network Installation. I don't have this issue with VM Workstation or with any physical desktops when I network book and connect to my WDS. I have a two physical socket 8 core processor with a secondary NIC. I created a virtual switch pointing to one of my NICs and when I start the PXE Boot it would load the WIM file at a slow rate and when it starts to boot up I get BSOD with a error of BAD_SYSTEM_CONFIG_INFO. I have been struggling on this for a few weeks and running out of ideas. Thanks.
Hi,
I installed 3 VM from W2012 Server eval. ISO
1.DC
2.W2012Node1
3.W2012Node2
created domain, added machine to domain,added failover cluster future and created cluster with W2012Node1 and W2012Node2
to facillated future VM creattion I build VM "templlate" = VM_template
on VM_tempalte I installed W2012 Server eval. then in "add futures" added failover cluser, and net 3.5 support(needed for installation of SQL2012)
then used SYSPREP to created clear clone of VM and saved.
created 2 copy of VM_template file and created 2 more VM, W2012Node3 and W2012Node4 and added then to domain.
on W2012Node3 I choose ..create new cluster browse ...
In available machines can see only
DC,
W2012Node1
W2012Node2
W2012Node3
W2012Node4 is not availabe!
I tried to create new cluster from W2012Node4 and got same result ,W2012Node4 is not visible
in DC -->active directories I can see all the computers including W2012Node4
Why W2012Node4 is not visibible from for cluster?
Can I modify some setting on W2012Node4 to make it visible for cluster ?

HyperV 2008 R2 Cluster with 2 nodes.
Host to Host traffic is as expected at 75-100MB/s. Inter VM traffic even when on the same host was at 5-6MB/s.
I installed latest firmware/drivers for all host nics. Disabled TCP Connection Offload, large send offload, RSS and Chimney globally using netsh, and Virtual Machine Queues. The speed improved to 20MB/s but this is still drastically slow.
We are also experiencing this on other 08 R2 cluster's.
Has anyone experienced this and found a solid solution? I have followed a lot of the other threads but no one seems to have a definitive answer/solution for this?
