I have a client with 2 Dell T630 Servers (practically identical boxes purchased about 6 months apart). One runs Server 2012 R2 Standard, the other Server 2016 Standard. Both run Hyper-V. Each box hosts one VM (VHDX files).

I have multiple backups of the 2012 Server (Altaro VM backups, Macrium backups of the physical box, and I’d also make direct copies of the VHDX files as well before proceeding).

The 2016 box hosts a VM with Server 2016 Standard acting as a Domain Controller. The 2012 box hosts a VM running Server 2012 Standard joined to the domain. It is not a secondary DC, etc. – it is only a member Server that runs a database program that multiple users access.

Note - the host boxes are not joined to the Domain – just the VMs are Domain members.

The 2012 R2 box has a hardware RAID 1 array for the OS (Dell Perc H730p Controller). Storage Spaces handles the Hyper-V VM files. The Storage Pool was created as a mirror using 4 Samsung PM863a SSDs.

I needed to add space to the pool. Added 2 more PM863a drives to the Pool. The problem is that 2012 R2 Hyper-V cannot optimize the storage space used, so the 4 original drives are ‘full’ (i.e., they show as being 99% full) and the 2 new drives are practically empty. As I understand it, the 2 new drives will get allocated any new storage as needed.

I’d like to take advantage of the new features of 2016 Hyper-V (one of which is the ability to optimize the storage pool). My question is how to best accomplish the …

Hello, so my 4 drive hardware backplane or RAID card is experiencing a failure, two ports are malfunctioning which caused the RAID to go in degraded state and cause a passthrough disk to fail.  SeaTools didn't find anything wrong with the drive, so I narrowed it down to either the RAID card, the cables, or the backplane, so yeah, rather than spend a lot of time with trial and error, I thought it might be worthwhile to replace all 3 components and try a different setup.

My existing Hyper-V setup involves two RAID arrays on separate cards, a RAID-5 (Areca ARC-1210) and a RAID-1 (Areca ARC-1200).  Both arrays are using Seagate Constellation drives.  The hypervisor boot drive is a standalone disk.  The RAID-1 is used for boot VHDs and RAID-5 used for Data VHDs.  So what I am looking at is replacing my current Areca ARC-1210 with an ARC-1220 which would get me 8 ports.  This would be enough to setup two RAID-5 arrays on the card and then I could stripe them in Windows Disk Management for RAID50.  I already have the six hard drives needed for this.

Let me be clear this is not a production environment, this is just a home lab.  Are there any pitfalls to look out for using RAID-50 with VHDs besides losing two drives on one array?  I don't have enough slots in the case to do RAID-60 and RAID-10 would leave me short on disk space.

Hello Experts,

I have a Server 2016 Core virtual that resides on a Hyper-V 2012 server.  
I am trying to activate it and I keep getting a error and it won't activate it.  It says syntax error

I am using
slui /ipk LICENSE KEY HERE

Any suggestions, I am ready to pull my hair out.  

Thank you,

Karen

Hello Experts,

I am hoping someone can tell what is going on here. I built a new Hyper-V host and migrated a couple of VMs to it from another host. When I went to modify members in the protection group I already had setup for hosts, it only shows Host Component when trying to add the VMs. The other hosts show their VMs. I even created a new protection group, and reinstalled the protection agent. It still does not show the VMs.

Anyone no what's going on?

Thanks!

We used the MSVM Converter 3.0 to migrate a W7 guest from Vmware 5.5 ESXI to Hyper-V 2012 R2. The conversion went smoothly, the computer boots up, but no network connection. The Driver shows as Error 31 Device is not working properly because Windows cannot load the drivers required for this update.  Things I have tried:

1) Removing the NIC, shutting down the guest, removing and readding the NIC to the guest from Hyper-V Management console. I have tried legacy and standard NIC's connected to different networks, without any change in behaviour. Both the Intel 21140 based driver and the normal Hyper_V Nic driver show up as the same error.
2) Set non_present devices to visible in command prompt and removed everything except the Miniport and other built in NIC's No luck.
3) As soon as I uninstall the nic and scan, it detects the NIC and instantly fails to install it.
4) Removed the config key from the registry for the current control set
5) Installed Integration Services.

IPCONFIG and NCPA.CPL show now network configuration.

The vmware tools appear to have been sucessfully removed during the migration (The machine was on during the migration).

There are other guests on this host which work fine that were also converted. They are using either the legacy or standard hyper-v nic connected to the same network without issue.

Because I can't get connected to the internet, getting updated drivers is difficult, however, given it doesn't appear to even be trying …

I've got several VMs on a Hypervisor that are being backed up with Backup Exec. My understanding is that on the VM recovery checkpoints are created, the VHDX is copied to tape and then the checkpoint is deleted. My issue seems to be that, with two of my VMs, those recovery checkpoints are not deleting. If I right-click the checkpoints none of them give me the option to delete them so it needs to be done manually. If I neglect to do this I eventually reach the 50 checkpoint limit and the whole VM will fail to backup.

Hi,
Firstly, I have to say the quality of answers from EE members has been EXCELLENT.
I am fairly new to server virtualization so excuse my ignorance.

 I virtualize a physical server that has C, D, E, F drives and the conversion creates one VHDX that has all the drives within it. I create my new Hyper-V virtual server using this VHDX and it has the C, D, E, F drives displayed but they're virtual drives with the ONE VHDX file.
But that doesn't seem to have the same redundancy as the separate physical drives on the original server.
Is it possible to virtualise the server and have  separate physical drives for the C, D, E, F drives?
How would the VHDX file recognize the  separate physical drives
I am not using a SAN. I have a server with lots of disk space

Please tell me what is the major difference between VHD/VHDX file which is created by Hyper-V and WindowsImageBackup.

Thanks

Hi,

I have inherited a Windows 2012 R2 Server running Hyper-V.  Currently, there is only one VM, for simplicity I'll call this VM1.  The former tech set up VM1 with AD and also has up to 10 users remotely log into that VM to work remotely using remote desktop services port forwarding 3389.  Besides the obvious security concerns of port 3389 open to the server--shouldn't separate VMs be set up?  Am I right that it's a security concern to have Remote Desktop Services and AD running on the same server or is that old school thinking?  I'm thinking that they should have a VM that does RDS and another VM that is their AD server.  They're running several SQL databases on this VM as well.  There's 40 GB RAM allocated for this VM.  Please let me know the security concerns and also performance concerns with this setup?  Thanks!

I am trying to get promiscuous mode working in a clustered Hyper-V environment.  The host server is running Windows 2012 Server R2.  Below I have the PowerShell command and the results that I get back.


Command:

$portFeature=Get-VMSystemSwitchExtensionPortFeature -FeatureName "Port Mirroring" 
$portFeature.SettingsData.MonitorMode = 2 Add-VMSwitchExtensionPortFeature -ExternalPort -SwitchName "MySwitch" -VMSwitchExtensionFeature $portFeature

Select all Open in new window

Results:

Get-VMSystemSwitchExtensionPortFeature : A positional parameter cannot be found that accepts argument '$null'.
At line:1 char:14
+ $portFeature=Get-VMSystemSwitchExtensionPortFeature -FeatureName "Port Mirroring ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.HyperV.PowerShell.Commands.GetVMSystemSwitchExtens
   ionPortFeatureCommand

Select all Open in new window

Can anyone tell me what I am doing wrong with my command?  The ultimate goal is to enable promiscuous mode on a single NIC so it can be used for Network monitoring.  I will then map that single NIC to a virtual machine.

I have server 2012, and the processor has 4 cores. I have a single virtual machine running server 2012 as well. I have an access database that all of the users are connecting to. About 15 users total. When I look at the CPU usage from the virtual server, it is only about 8%. When I look at the Virtual Machine's CPU it's maxed out constantly. I see I have only one core (Virtual Processor) allocated to that machine. How many can I dedicate to that machine if I have 4? I need that machine to run as smooth as possible!

I learned about the Cores here CORES

We have a Windows Server 2012 R2 STD running Hyper-V hosting some VMs. One of these VMs is our File server, also running Windows Server 2012 STD R2.  
The D: drive keeps getting near to full and I have increased the size a few times.
At 5TB there is only 61GB free again.

I ran a file size scan and it only show 2.6TB of files.
What can be taking up all the other space? Can I defrag a Virtual drive?
