MVMC 3.0 - Retain Block Size?
I have an Exchange 2007 server (Windows Server 2008 R2) on ESXi. I need to convert it to Hyper-V 2012 R2, but retain the 512 byte block size. Can this be done with MVMC 3.0?
I tried 5nine Converter, and it converts the 512 byte vmx files to 4K vhd files, which Exchange does not support.

Hyper-V 2012 R2 Cluster Creation Fails
I am trying to create a 2 Node Hyper-v 2012 R2 Cluster. The Cluster Validation passes with no errors or warnings but the the cluster creation fails.
The error is similar to here .
In this case he solved it by joining the Nodes to a Windows 2012 Domain. We don't have that option in our environment.
In the System Logs Events 7024 The cluster service terminated... The cluster join operation failed, and 7031 Cluster Services Terminated unexpectedly.
Anyone have an idea?

Re-attaching VMs in Server 2012 R2 Hyper-V?
Is there a way to re-attach VMs to a Hyper-V server? My Server 2012 box died, but as my VMs were stored on another disk (D:\) I thaught I could quickly put this VM-disk in my 2012 R2-box and re-attach the VMs.
I know the proper way is exporting and importing, but I couldn't export the VMs properly so I choose to register the VM, and it comes with an error:
The wizard cannot import virtual hard disks from source folder 'D:\Vms\VM1\'
Failed to get the disk information.
Failed to open attachment 'D:\VMs\VM1\VM1.vhd". Error: 'The file cannot be accessed by the system.'.

Windows Server 2008 R2 hanging
Hello
We are running Windows Server 2008 R2 with Hyper-V and several VM's. Occasionally the server will gradually grind to a halt and when you try and logon it hangs at the welcome screen and all the VM's become unresponsive.
After physically powering down and rebooting there are no useful event errors and a debug log is not generated. It is a HP server and the logs do not indicate any hardware issues. Is anyone familiar with these symptoms or are you able to help me better diagnose the symptoms.
The virtual host and all of the virtual machines are domain members on a server 2003 schema domain. There are 5 VM's running the following roles:-Server 1 - Exchange Server 2010
Server 2 - File and print services
Server 3 - SQL/Database server
Server 4 - Navision Access Server
Server 5 - SQL/Database test server
All have sufficient resources. This is a small 40 x user environment.
Kind Regards

Why Hyper-V, images, and virtualization?
Good morning, TechNet.
I'm trying to understand and learn about virtualization, but most results on Google are on the "how's" and not on the "why's". From what I can gather:
- This is related to .iso images. Suppose I create a new VM with some OS. I can burn this onto a CD somehow using the "how's" as mentioned above.
- There is something called a snapshot which updates or patches these images.
- From these two points, I believe that an image is similar to a portable system: if I have an image of the OS on the CD, I can mount that onto another VM and it'll create another instance of the OS that is completely separate from the original, but holds the same settings, etc. (Please correct me if I'm wrong).
What I'm having difficulty understanding is: 1) If I am correct in the slightest way (my knowledge is so abstract that it might as well be a Picasso painting), 2) why is this necessary (is it to bypass the repeated need to install the OS on different VMs? And instead 'boot' it up from this image?), 3) how do these patches or snapshots get added to the .iso.
Edit: A few more questions and grammar fixes:
- If I mount the iso (if this is even correct), does the disk have to stay with the computer.
- What should be implemented by the time I create an .iso image? Should the system have updates, or should it be as fresh-out-of-the-box as possible?
I apologize for the wall of text, but thank you for your time.

Disk Configuration Question for Performance
Hi,
I am looking for some advice on what the best way to configure my disk system is for performance when using Hyper-V. Currently I have two midline 7.2k SATA disks used for the hyper-V OS in RAID 1, and then 14 x 10k 600GB SAS enterprise disks in RAID 10. The RAID 10 is where all my VM’s exist on, but not directly on the physical disk, I use a product called StarWind which consumes almost all of the physical disk space, this is a virtual SAN and I use this for my CSV in the cluster, the VM’s all exist on this starwind disk, there is a tiny amount of overhead but I don’t think that’s really where my problem lies. We have 12 Virtual machines, so there is 1 spindle per VM, however it’s in RAID 10 so does this actually mean I have 7 spindles for 12 VMs?
The entire system almost grinds to a halt whenever I am copying new VM’s onto this host. I can’t use any other RAID type except for RAID 1 or 10. I know RAID 0 would give me better performance but we are not willing to take the risk. Now, it is my understanding that RAID 1 and 10 are essentially the same with the same performance and capacity, because of this I chose RAID 10 so I can take advantage of the combined capacity, but I am wondering if this is the best configuration.
I can think of a few other variations:
- A single RAID 10 with one large partition but multiple CSV’s instead of one large one
- A single RAID 10 with multiple partitions and a CSV on each partition
- Multiple RAID 1, each having a single partition and a single CSV
Reading this site, there are a few pointers I have taken away regarding disk performance, a couple below I have questions about.
http://www.altaro.com/hyper-v/23-best-practices-improve-hyper-v-vm-performance/
Point 6 says “Use separate volumes for each VM. Since the administrative tasks of a virtual machine are controlled by its own process (VMWP.exe), keeping several virtual machines on a single volume will cause more Disk I/O operations from each worker process. Hence, it is recommended to use separate volumes for storing virtual machine files (VHD, VHDx, checkpoints, and XML).”
Does this mean the arrangement I propose in my second point above – multiple partitions and a CSV on each partition? The term “Volume” seems to be a bit ambiguous depending on where you read
I believe point 14 to be incorrect though. “De-fragment Hyper-V Server regularly or before creating a virtual hard disk. It is advisable to defrag Hyper-V Server disks where the VHD and virtual machine configuration files are stored regularly or before creating a large virtual hard disk file.”
It is my understanding that defrag only tends to work well if there are many files on the disk, on the physical disk in my case there is one massive starwind file so I don’t think defrag on the physical will do anything, defrag in the starwind disk might help but it is mostly large VHDX files – will defrag really make much difference?
Additionally, I don’t have any generation 2 VM’s and there’s nothing I can do about this right now, all data disks use SCSI channels on the VMs, all VHDX are fixed size.
Also, a slight side question but kind of related – I have both an exchange server and SQL server running as VM’s (the log files already exist on separate VHDs, but on the same physical RAID 10 disk), does my physical disks used for log files need to match those used for the DB, or can they be slower lower class disks… for example, if I place a 7.2K disk in with a RAID made up of 10K disks, it is my understanding that the entire RAID will lower its performance of the slowest member – is this true with log files and databases, if the log files are on slow disks will the database also go slower to match the pace of log files being written?
many thanks
Steve

cannot delete a checkpoint HV 2012 R2
Hi,
I have a non critical VM (W7) with a problem related to a checkpoint. Would like to resolve it.
I did a revert. It worked fine. When click Delete a checkpoint/or tree I get an error (see screenshot). Event viewer is clean.
When click revert again it shuts down the machine. The machine is functional.
Found the same issue on web but no resolution...
Any tip on how to tackle this?
thanks.

Virtual Machine Could Not Initialize
I have been stuck troubleshooting this problem for over a week with hyper v. It is for any kind of VM I am trying to start, I get 'virtual machine name' could not initialize and that is all that is stated in the event logs. I am running windows server
2012 R2 and have never got hyper v to ever work. I made sure to configure the bios correctly and power flushed the server after and recreated the VMs and still nothing. I have tried assigning the maximum amount of resources and still nothing and I am not sure
what else to try... any ideas?

R710 VM's and Hard Drives
R710
Quad Core 2.26GHz Intel Xeon E5520 8MB Cache
24GB DDR3 1066MHz (6 x 4GB 1066MHz Modules)
Running
(2) Windows Server 2012 R2 Standard
Windows Server 2012 R2 Hyper-V Host
VM-1 = AD DS, DNS, DHCP
VM-2 = Peach Tree/Sage 50 with 4 users connected
VM-3 = Time Clock Plus software connected to 5 Users
VM-4 = File Storage Service and Print Services for 25 Users
Does this make sense?
What HDD configurations should be considered?
Example:With 8 Bay server
(2) 128GB HDD - Raid 1 - HOST
(4) 300GB HDD - Raid 10 - Partitioned into volumes for each VM
Volume 1: VM1 - 100GB for AD DS, DNS, DHCP - 100GB
Volume 2: VM2 - 100GB for Peach Tree/Sage 50
Volume 3: VM3 -100GB for Time Clock Plus
Volume 4: VM4 -100GB for File Storage Service and Print Services for 25 Users
(2) 2TB SATA - Raid 1 - File Storage
Eventually I'll go with ISCSI-NAS for user file storage but right now I can't. What are your thoughts?

Could not connect to VM from RDWeb that is created from 2008R2 then migrated to Hyper-V 3.0
I have a VM created in 2008R2. For some reason, I could not recreate the VM because its installed with an application that only vendor can install. So my only way to migrate the VM to 2012R2 is copy the VHD.
I created unmanaged collection on 2012R2, created a new VM and attached the VHD. Add the new VM to unmanage pool. Everything works well. I could run the VM from Hyper-V except I could not connect to it from RDWeb. I followed the instructions from http://blogs.crayon.com/2014/07/04/migrated-vdi-virtual-machines-hangs-in-the-loading-the-virtual-machine-state/ because I have very similar problem but no avail.
Is there anyway I could make it work?

Server 2012 R2 w HyperV Role - Guest NICs disconnecting during backup Event ID 12598
Hello, we are seeing Guest VM's disconnect from the network in the event logs during our backup window. We are using CommVault 10 SP8 on Hyper-V 2012 R2 with Hyper-V role, we are fully patched and using the current Integration Services. We see this on both stand alone Hyper-V servers and clusters. The servers are being backed up with VSS and are not going into a saved state as far as I can tell, they are being hot backed up.
We are seeing event ID 12598 network adaptor disconnected from virtual network on the host logs under Hyper-V-SynthNic. I would like to try and stop this from happening so monitoring software will stop marking servers offline. Any ideas?

How to convert offline ESXi 5.5U1 virtual machines to Hyper-V?
Following on from my earlier question, I am having trouble working out how to convert my ESXi VMs to Hyper-V. Am I doing something really unusual?
I have a ESXi 5.5U1 server at home for my home test lab. I want to convert this to Hyper-V Core 2012 R2. Target storage layout will look like this:
Currently under ESXi 5.5, I don't have the C drive (using a USB flash to boot), and the RAID-5 and RAID-0 arrays are two separate VMFS volumes.I don't have swing kit to migrate, I have to repurpose existing hardware. I do have my Windows 8.1 workstation but that only has 900 GB free space.Some of my VMs have vmdks greater than 2TB.
My plan was to
- In ESXi before rebuilding, move my VMs from the RAID-5 vol to the RAID-0 vol and then delete anything that wouldn't fit that's not strictly necessary from the RAID-5 volume.
- Shutdown ESXi and remove the USB flash drive.
- Install Hyper-V onto the System disk as C drive.
- Format the RAID-5 volume as NTFS (64k) and create a mount point into the C drive as C:\RAID-5. Put my VM disks in C:\RAID-5\VirtualDisks and the VMs in C:\RAID-5\VirtualMachines.
- Somehow convert the VMs from the RAID-0 VMFS volume to Hyper-V VMs on the RAID-5 NTFS volume.
My confidence is low because I have tried to convert a new test machine created in ESXi 5.5 to a spare test Hyper-V 2012 R2 with the MVMC 3.1 converter and it failed. I also tried with the free 5nine converter and that failed too. I tried with and without the Guest Additions installed. Both conversions failed. I should mention I am in a workgroup, not a windows domain.
Please help!

configuring for Dynamic optimization - a dummies guide?
I am new to HyperV 2012 R2 and SCVMM.
Looking for a recipe that will allow me to cause VMs to live migrate between hosts in a cluster, via the SCVMM DO feature. I have a 3 host cluster with requirements (common network names, CSV-based shared storage, compliant Host servers) for live migration.
I can live/quick migrate VMs between the hosts in the cluster, but am stuck trying to configure the host reserves and VMs and ???, so they (VMs) will migrate via SCVMM and DO?
Assume all of the VMs were created before SCVMM was installed, and only a cluster existed.
thx!

Creating a VM?
Hello Community
In WS2012 you install Hype-V.
To create a Virtual disk (VHD) you can go into Disk Management,
right click and chose create VHD.
But a VM/Virtual Machine uses the VHD to store data, etc on.
That leaves the question of how to create the (VM)/Virtual Machine
that will use the VHD to store its data on?
Thank you

Virtual Desktop Collection Provisioning - Issue with Naming
Hi all,
I have created a Virtual Desktop (Pooled) Collection using Hyper-V in 2012 and an RD Connection Broker.
My question is pretty straight forward, though I cant seem to find an answer anywhere. If I add a machine to the Virtual Desktop Pool using Tasks > Add Virtual Desktop, and the job subsequently fails, I cant see an obvious way to clear/retry the job.
If I use a naming convention like RDP00, RDP01, RDP02 etc I have found that on subsequent jobs, the next computer name in the sequence (that would have been created in the previous failed job) is skipped, causing me to have machines that are not sequentially named.
This is kindve annoying, and I was hoping that there would be some way to delete/retry the job to add a Virtual Desktop.
Input would be much appreciated - It's very possible that I have simply missed something.
Thanks, and Merry Christmas!
Tom
