Performance - Dual Boot to VM running Server and running multiple Hyper-V VMs on that server?

October 9, 2016, 11:07 am

You'll understand why I'm posting this to Hyper-V instead of Windows Server 2012 R2 Installation category as you read the post.

Introduction & Purpose:
I want the capability to dual-boot to either Windows 10 Pro or Windows Server 2012 R2. I want to create various labs using Hyper-V running on Windows Server 2012 R2. (I realize that I can create and run Hyper-V VMs from within Windows 10 Pro but I want to run them under Windows Server 2012 R2.) The labs will include small networks consisting of Windows Server 2008 R2, Windows Server 2012 R2, Windows 7, Windows 8.1, Windows 10, and perhaps a Linux OS. The servers roles will include ADDS, DNS, DHCP and other common server roles. I plan on using these labs for learning purposes with a focus on learning how to upgrade, configure and administer Windows server and client operating systems and improving my PowerShell skills.

MEMORY (RAM): 32GB

STORAGE
I have the following storage available:

  1. 500GB Western Digital Black SATA disk drive with 310GB free space. (Used for Windows 10 OS and Apps)
  2. 1TB Western Digital Black SATA disk drives, 3 of which are new and unused and the 4th drive has 391GB free space.
  3. 2TB Western Digital Black SATA disk drives which is new and unused.
  4. (OS resides on disk C:) or I can boot to a Windows Server 2012 R2 VHD (which is installed to boot from VHD).

I am considering the following options for the dual-boot setup: (Windows 10 Pro is already installed.)

  1. Create a 2nd (3rd really) partition on my existing C: drive and install Windows Server 2012 in that partition.
  2. Install Windows Server 2012 R2 as a VHD(x) and configure the system to boot to the VHD when I select the Server 2012 R2 boot option.

My concern with Option 2 is this: Will the Hyper-V VMs that I create in the virtualized instance of Windows Server 2012 R2 (Option 2) perform as well as Hyper-V VMs that I create in the non-virtualized Windows Server 2012 R2 installation (Option 1)?

My knowledge of Hyper-V and virtualization in general is very limited. But doesn't Option 2 create conditions in which "a hypervisor is using another hypervisor" which will result in sub-optimal performance?

I truly hope my post makes sense. If you have any questions, please don't hesitate to ask. I seek assistance because my goal is to set the environment up right the first time and obtain the best performance possible given my hardware.

Hyper V Containers

So i am trying to understand containers in server 2016 (tp). The articles i have read talk about "applications" running in the container. Server OS could be an "application" and hyper-v could be an "application". We are a services company and offer some services to clients (like system monitoring). What really interests me is the isolation but i am thinking in the realm of malware/hacks. If a VM running in a container gets hacked or infected with malware that spreads to the network and other PC's/servers/VM's then running in a container will prevent the spread? I'm trying to decide if VM/OS containers will benefit our business.

hyper-v external switch disabled anyconnect vpn

From my hyper-v host (windows 10), I was running anyconnect vpn.

The vpn was operational after I started a hyper-v client (linux) when following a docker for windows tutorial.

The vpn stopped working after I started a hyper-v 'external network switch', as per this link in the docker website: https://docs.docker.com/machine/drivers/hyper-v/

I doubt my IT department can help me restore the anyconnect vpn.

I'm looking for a starting point on how to isolate the problem and restore the vpn, myself.

My skill level: long time linux based software developer, with moderate understanding of IP networking.  No experience with windows admin, or networking.

Can any reader direct me, please?

Thanks

Hello,

We are about to buy a new host server to replicate with our existing 2012 R2 server.   We don't have the budget to buy 2016 for our existing host.   Anyone know if you can replicate from a 2016 server to a 2012 R2 server?

Thanks

Access Denied Moving VM Storage in Failover Cluster

October 10, 2016, 4:32 pm

Looking for some ideas on how to fix the Access Denied issue.  VM is running, but feel performance is slow as a result of the security issues.

I am unable to move a VM storage using Failover Cluster Manager and our backups continue to fail on this specific volume.  I have Veeam backup and a Nimble SAN is the CSV provider.  VSSAdmin shows the Microsoft Writer with an error.  I have communicated with both Veeam and Nimble and they have tried many different fixes with no luck. I have tried just about every possible solution on the internet with no luck.  Here are the steps I have tried and the results:

1. Ran the icacls command to set the hidden VM permissions on the volume and the subforlders and received Access Denied.  Still get Access Denied in FCM Move utility.

2. Shutdown the VM and tried to run the icacls command to set the permissions and received Access Denied.

3. Took ownership of the CSV volume and rebooted the Host and still get the Access Denied.  Applied hidden permissions using icacls and still get Access Denied.  Tried to move the VM storage with same result.

4. Created a new volume and copied all files from old volume to new volume and tried to apply the hidden permissions.  Still no love!!

5. Removed the Hyper-v role in Failover Cluster Mgr and tried to move the storage using Hyper-V Manager.  Still no love!

6. I added the Hyper-V role back in Failover Cluster Mgr and attempted to move the VM again with the thought that adding the role would reset the permissions, but still not love!

Here are links that I have used for reference:

Hyper-V Cluster (Disk Overwrite)

Hello all,

I've created a cluster that consists of two nodes. We've created some VMs and everything was great. By Mistake, one of my colleague destroyed the cluster. We did not have a cluster for awhile since the hyper-v servers were not production yet. Now we're planning to create the cluster again.

The question is would the cluster manager overwrite the contents of the shared disk?

BTW, number of VMs were created on the shared disk after the cluster was destroyed.

Regards.

SMB3-Hyper-V: Generell Access Denied Error

HI,

iam currently stucked with a problem. I have a test setup with 2 Server 2012R2 Core Machines, clustered and managed by a SCVMM 2012R2 installation.

The VM hard disks and configuration files are stored in an SMB3 file share. Everything works fine when i do a roll out via the scvmm console. But a soon as i start deploying a new VM via the Failover Cluster/Hyper-V Manager console i get an "general access denied error"

Also when i try to change the default path for vhds and configuration files within the Hyper-V Manager i get access denied errors. I checked the security settings at the share and i don't see something missing.

Thanks for any tips that would lead me to a solution :)

Adicionar um novo domínio a uma floresta existente

Boa tarde!

Na nossa organização temos dois dominios: dominio-A e dominio-B. Para acabar com os dois dominios e criar um unico dominio de gestão, pretendo criar um novo dominio-C. 

Gostava de saber quais as implicações que tem nas aplicações existentes, Emails, etc.

Pretendo seguir os seguintes passos:

-criar um novo domain controller com um novo dominio dominio-C

-para os novos pcs e servidores que se criem, adicionar ao novo dominio-C

-os pcs antigos ir mudando gradualmente para o novo dominio-C.


O nome do dominio que quero criar vai ter o mesmo nome que tem actualmente o do email xxx@dominio-C.

O facto de criar um dominio com o mesmo nome que é usado nos emails traz algum problema para os emails? Não sei se expliquei bem o que pretendo...

VMs Very slow on 2012 R2 Server - Teaming Done

i am not sure what i am missing but we tried all combinations, changing hardware etc but VMs on these heavy servers are very slow. I just moved few Vms from my other infra to these HP DL 380 G7 servers with 128Gb RAM .. configured in two node cluster windows 2012 R2... but now when i give a ping to the VMs in the LAN .. the time ranges from 100+ms to 200ms which should be less then 1Ms...

VMs takes ages to start... it looses connection to storage ... cluster looses connection to nodes.. ufff.. loads of stupid things happening and i am really not sure whats the cause.. also to let you know ... this is not the first time i am working on clusters so i have quick good knowledge on clusters but this is really eating my head...

I have done teaming with Cisco on other side... 2/4 lan card but both cases ping is horrible... its dynamic config for teaming so i have not not configured anything on switch side.

Any guidance will be much appreciated. please.


Thanks, Happiness Always

2 node Server 2012 R2 Cluster
~40 VMs on cluster

Trying to live migrate VM from CLUSTER-NODE1 TO NODE2

Tried both VMM and Failover cluster manager.

VMM gives this error
Error (10698)
The virtual machine could not be live migrated to the virtual machine host using this cluster configuration.

Recommended Action
Check the cluster configuration and then try the operation again.

Event log on CLUSTER-NODE1. Nothing logged on destination host

I have migrated this machine before between the nodes and I can still migrate the other 39 machines between nodes. I have rebooted this VM, but no change. No checkpoints on the VM. 

In my search for an answer, it seems that the error message is incomplete. I have found other posts with the error "Virtual machine migration operation for 'VMNAME' failed at migration source" but they always have an additional piece of the message, like authentication failure etc. This error does not give any indication of the cause.

Replica between Server 2012 (non-R2) and Server 2016

Hi guys,

I'm kind of in a pinch here so any help would be appreciated.

So, my company is helping set up Hyper-V Replica for a client for their new DR site. The thing is their production/primary servers are running Server 2012 (not R2) but the servers on the DR site might come with Server 2016.

I know replication can't be done from 2012 R2 back to 2012 so I'm assuming replication is also not going to work from 2016 to 2012. Am I right to assume this?

I did read that when you import/move a VM from 2012 R2 to 2016, it will not be automatically updated so you can move it back to 2012 R2, but again, our client is using the non-R2 2012. So my question is, does this also apply to 2012?

Thanks in advance.

I've installed Hyper-V Core 2016. When I RDP into the machine I get a warning message "Remote Desktop licensing mode is not configured - Remote Desktop Services might stop working in 120 days". I never got this message on Hyper-V Core 2012 R2.

So is Hyper-V Core 2016 still free like 2012 was? If so how can I fix this licensing mode?

To Jumbo Frame or not to Jumbo Frame - That the question..

Hi everyone,

Currently on Windows 2012 R2 Hyper-V servers.

Network infrastructure switches and NIC is all on the SAN and LAN configured to handle Jumbo Frames.

on the management, SAN and Live Migration Network in Hyper-V we have configured Jumbo Frames. I can test with "ping -l 8960 -f IP" and see that I get ping reply.

Currently the VM switch is also configured to Jumbo Frames. I'm 100% sure that 99% of all the Guest VM's which normally is Windows OS is not configured to handle Jumbo Frames. What is best practice to do?

If Jumbo Frames is configured all Places on Hyper-V host and Guest OS, will it make performance worse if it is a Remote Desktop servers which internally LAN communication can use Jumbo Frames, but when "talking" to the Default Gateway always need to use 1500 bytes packets..
