Hi,
I'm trying to rename a VM, and I've succeeded in all Fields, except on the name in the summary of the failover cluster (Zsap03 is the name I want and that is appearing in the menu and everywhere, and it is appearing Zsap03V1 on the virtual machine summary)
How is it possible to change it?
Note: I've changed on the Hyper-V Manager, on the failover cluster properties of that VM and also on the settings. I can't find anything else to find.
I'm in the process of building out a new application, and I'm wondering if there's any performance difference between using single VHDX per VM vs multiple VHDXs.
Here's the basic idea:
The application in question recommends hosting your MSMQ data and logs on a separate disk from the OS. Assuming the base aggregate can handle the IO, is there any performance difference between putting the OS on one VHDX, and the MSMQ on a second VHDX, versus using a single VHDX for all of it, if it's all stored on the same CSV anyway?
Thanks!
Dear all,
I have windows server 2012 R2 , I have created the cluster of two nodes. I have only one drive in cluster.When I create one folder in that drive & trying to share that folder, I am getting the error as in the screen shot . Although the resource is online on the same node. I have also failover the disk on another node & tried to share from there, but it doesn't work.
Please help.

Hi All,
Currently have 10 Hyper-V Hosts, all running on Cisco C220-M3 server. Virtual Machines running Server 2008R2/2012 on traditional layer 2 network are having high TCP retransmission rates between VMs across the hosts. (Keep in mind their is no
Layer 3 involved here). Switching fabric is a Nexus 7k, each host having 2 x 10G uplinks for VM traffic, and 2 x 10Gbps for SMB traffic. We are currently experiencing excessive TCP retransmission at the VM Guest layer, Most testing has been
around the Server 2008R2 SP1 VM's. vSwitch is configured for switch independent mode. Things to note is, that its not related to high throughput on the interface, in fact its quite low approx. 10Mbps average.
Wondering if anyone else is having any experience like this in their environment around TCP retransmissions. Adapters do have Absolute Bandwidth control with upper level set to 1Gbps.
Hello team,
I've been experienced an issue that is affected the performance of my environment. I have the following scenario:
1 - Server Dell R720
1 - SAN DELL MD3220i
1 - Switch Cisco 3750G
As the picture shows, I just have a switch, I'm pretty know that the recommended setting is with two switches, however I just have one of them. A personal of Cisco has configured this device with different vlan's so that means that the connection between the storage and the host works so nice.
The problem is the latency that the virtual machines are experiencing. I have Windows Server 2012 and I'm using Hyper-v to virtualize my virtual machines.
Does anyone know which parameters May I need to modify, enable or disable on Windows Server 2012 - Hyper V to work fine?
I would appreciate your help in this regard!
Thank you in advance!
Regards,
Paul Mendoza.
This is happening every time any VM is loaded. The server was rebuilt with Server 2012 R2 Datacenter edition.
VMs are using Generation 1 .vhdx disks. This issue occurs with IDE and SCSI controllers.
Task sequence starts but when attempting to format the disk, the disk returns 0 bytes free. This happens 100% of the time. Attempting to use diskpart to create a partition and format is about 40% successful. When it fails several errors could be returned, sometimes it seems to be losing contact with the virtual disk controller.
This is our lab server and worked great previously with Windows 2012 Standard Edition. Any help/pointers would be helpful, I'm completely lost as to why this would happen.
There is a tool that can recover logical problems in the VHD structure?
A friend called me and told me that his VS R2 Enterprise with 4 VMs suffered a power falure and after that, one of the VMs does not startup anymore. The erros is the same as using VHDMOUNT, something similar: "VHD file could not be mounted"
There is a CHKDSK for VHD files?
How to "rebuild" a corrupetd VHD file? How to analyze logical structure of a offline VHD file?
Hello,
I really cannot find anything that talks about presenting both Iscsi and fibre (fcoe) LUNs to 1 hyper-v host. I doubt that it is very wise to mix fibre and iscsi storage on 1 hyper-v host.
Hi,
Just built a Server 2012 R2 Hyper-V failover cluster connected to Equallogic 4110 storage arrays with latest firmware and HIT kits.
When creating a clone or vm from a template we see that the cluster loses access to the storage csv volume that is hosted on the equallogic storage with the following errors:
Cluster Shared Volume 'Volume1' ('CSV Disk1') has entered a paused state because of '(c0000435)'. All I/O will temporarily be queued until a path to the volume is reestablished.
Can anyone shed any light onto this issue?

I´m doing backup using a simple script in my WIn2012R2
A batch file is combined with a simple set of commands in a diskshadow.txt file (see below)
There´s NO snapshots created (ever) and in the log file The robocopy part of the script) it appears:

I've got a hyperV 2012 system with several VM's. One of the VM's has thrown a BSOD a couple of times in the last month and I was wondering if the procedure for figuring out the cause is a little different under hyperV.
The BSOD I'm getting is a memory management bugcheck 1a. The crash dumps don't show any "smoking guns":

Googling around for this issue points to memory HW problems in the computer but being a hyperV system with many other VM's active I don't see how that could be it. The VM in question is a server 2008R2 in "terminal server" mode, fully patched. Nothing of note in the event logs and nothing (other than updates last month) was done on the server lately.
Any ideas on how I could proceed to track this down? Thanks.

Hi,
We are looking to move from physical fileserver to Hyper-v Virtual file server.
we will use SAN storage to store VM's .
Existing data size is around 5TB and expected to be in next 2 years is 10TB.
It is recommended to Go for Hyper-V virtual file server?
what are the best practices for this?

What is cluster and how configure setup cluster between virtual machine (with in Hyper V and between Hyper V servers). how to test cluster is working in both scenarios
Hi,
I have standalone hyper-V server 2012 R2 media for installation and a server which can be configured to boot from SCSI (No local HDD) from BIOS.
I have done the configuration for BIOS to boot from SCSI, I put the installation media for hyper-V and it starts loading but in the installation it is not able to detect the SCSI volume (HDD)..this is the problem.
I followed the same with win server 2008, it works fine. But with hyper-V it is not working....please give me a solution as what to do.
Hi,
I have Failover Cluster running Windows 2012. This cluster is hosting an Exchange 2010, a Virtual Domain Controller (not my choice) and a VM running McAfee ePO. Theses VMs represents 1 TB of data.
Requirement:
I need to design and implement a backup routine for these VMs.
Help, please. I need some advice based on best practices. I have 7 TB of space for the backup. I am planning to deploy Altaro Hyper-V Backup v5 o Veeam v8.
How many “full backup” do I need to keep for Exchange 2010 and for how long?
How many “incremental backup” do I need to take?
The same applies for the Virtual DC and the VM running McAfee ePO.
Thanks in advanced.
I'm trying to import Hyper-V 2008 (without R2) VM to Hyper-V 2012 R2 host.
This error occured:
"Hyper-V encountered an error during the import operation.
'VM' failed to realize.
Failed to upgrade the VM version of the virtual machine 'VM'.
The VM version is not supported"
Dear All,
We have 4 Hyper V VM installations on 2 HP DL 380 G8 servers and have they are connected to HP NSA 2040 SAN Storage through 6 Gbps Fibre channel. The physical machines are clustered.
Out of the 4, 2 are Clustered Hyper V's running Microsoft Dynamics AX 2012 R3 and we have 2 Clustered Hyper V for Database server running MS SQL 2012 R2.
The issue here is that the APP servers are slow in communicating with the DB server. The Hyper V's have a dedicated 4 * 1Gbps interface cards teamed and the packets are getting timed out. But from any other machine in the subnet the communications are proper.
When ever i try to copy a file from the DB server to the APP server using SMB share it kills my network, the copy will happen but after the copy is completed the network comes backup.
Its strange scenario. APP server 2 APP server smb copy is fine, and from DB to DB smb copy is fine but cannot copy between them.
Can anyone please help?
Thanks,
Sriram A Das
Hi
Setting up a Server 2012 r2 Hyper-v host with an onboard 4 port 1 GB nic and a offboard dual port 10 GB nic. We are using the 1gb quad port for management. The 10 Gb we intend using for hyper-v guest use however we don't seem to be able to achieve very high speeds though the 10 GB adapter when assigned to a virtual switch. Testing the 10 Gb nic from the host confirms that we can transfer/get 10 GB speeds. When assigned to a virtual switch however the speed drops to about 1-2 Gbps. Has anybody seen anything like this ?. We've tried a variety of settings and i can confirm that the network traffic is using the 10 GB nic.
