Hyper-V

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Free Tool: SSL Checker

Scans your site and returns information about your SSL implementation and certificate. Helpful for debugging and validating your SSL configuration.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

We are setting up our First Virtual enviroment in Hyper-v.

We want to know if its best practice to have the file server separate from the DC.

Or should we just create a C: drive and a separate Partition E: on the DC for the shared folders.

we do have enough licenses for 3 VM's.

Also we would like to know what is the difference between raid 5 and 10 for redundancy?

I have a VM that is quite large (2TB) that I need to
move from a physical server to another temporarly so that I can format the original server and re put back that VM there.

what is the safest way and the least disruptive ?
do I create a replica on the other server and once replication is done then i fail over ? or do I export and import the VM ?
Exporting  and importing will take around 20H which i could eventually find on a Sunday (no need for the VM to be up).
But replica is smoothier... and will not need the VM to stop but for few min..
My only concern is that once the replica is ON and the original server is back online can I again do the same ? replica from the replica to the main server ?

Kindly your experience ....

Thanks

Ultimate goal is to have RDS running on server 2016.  Per Experts advice, I have now re-created new physical server as Server 2016 standard running the Hyper-V role; created 1st vm as serverA running Server 2016 with roles of ADDC, DNS, DHCP; 2nd vm as serverB with Server 2016 and attempting to add RDS role quickstart deployment.  I see this server but it states that cannot deploy because "unable to connect to server by using Windows Powershell remoting".  Both servers are in same domain, can see one another, have only 1 user, administrator, so far, firewalls on both are turned off, tried Powershell Enable-psremoting -force on both.  I am new to virtualization and don't know if I have missed steps in the setup of these 2 servers that would cause this issue?  Are there networking issues I am missing?  Where do I go from here?  Any help is appreciated.

I have a 2012 Server R2 Standard Hyper-V VM (Server1) that has Remote desktop services with all the roles on it. This is for Published Apps. I setup a second Hyper v VM (Server2) to replace Server1. I access Server1 by going to http://rds.domain.com/rdweb and the cert is for rds.domain.com. I can access this fine and open the apps.  I access Server2 by going to http://access.domain.com:8443/rdweb and the cert is for access.domain.com this is a self signed cert for now. When i go to http://access.domain.com:8443/rdweb and login and run an app i get this error " Your Computer cant connect to the remote computer because the remote desktop Gateway server address requested and the certificate subject name do not match." If i select view certificate i see the Server1 cert rds.domain.com.

I think this has to do with port 3389 and that when i launch the app its pointing to the server1. Is there a way to change the port on Server2 if this is the issue?

Hello Experts
i need some advise on best way forward to setup a 3 node hyper v failover cluster using windows server 2016.
I got 3 Dell Servers all identical config,  and 1 dell SAN storage. 2 Dell iSCSI 10GB swithces,  2 Cisco c3750 switches, 1 dell server to act as standalone DC.

i have been doing 2 node clusters in past but never done a 3 node cluster. so need some advise on network config as in 2 node cluster i used to connect two servers via direct crossover cable for cluster heart beat etc and use cluster quorom disk .

so any tips will be much helpful.

thanks

Physical server died, it had 3 VM's running on it.   Physical server was a windows 2012 r2 standard
We were able to extract the manual copies of the vhds, snapshots, and the config files. some of the vm's had multiple snapshots.

we have a spare server that we loaded, also with windows 2012 r2 standard and installed hyper V on it.
What's the process of importing the VM's onto it (keeping in mind that they have snapshots, etc).

14 Hyper v hosts, managed via SCVMM running on a c7000 blade chassis with 10G interconnects - All intel CPU's, 192 GB RAM etc. Broadcom nics but vmq disabled.

Dell 10GB switch managing ISCSI to the chassis and SAN.

IBM v3700 with 2 expansion trays.
5x400GB SSD's in raid 10 for easy tier, 4 x raid raid 6 arrays of 10k disks. (lets call it 8 disks each array) 1 x large Raid 6 of Nearline drives.

The environment is well loaded and runs fine running a varying number of VM loads.

We monitor extensively all performance etc and know that there are no issues with CPU, memory or disk access etc UNTIL:

If a backup is misbehaving, someone is doing a high disk load activity or something like deploying a templated VM, all users across all VM's notice a slowdown or lockup.

DISK IO on the SAN is neligable, Ram usage, CPU Usage does not spike and there only a small increase in the amount of network traffic.

It seems like everything runs well, but just a small event can cause issues.

Looking for ideas, configuration changes or otherwise.

We have a two server boxes in a HA Cluster setup

When a node is shutdown, the VMs on that node are not appearing /migrating to the other node thats in the HA cluster.

When both nodes are on, VMs can happily migrate from node to node without a problem.

Why is this ?

I've got a Win 10 Pro laptop with 16 GB of ram. I've got Hyper V installed & another Win 10 VM running on it, for working with point of sale software.
In settings, I've specified 8 GB of ram, dynamic is enabled, 512MB min & 1048576 max (not sure where I came up with that).
System properties shows 7.91 GB installed & 1.88 available, which is about what task manager shows.
How can I increase this? Uncheck dynamic?
I'm in the middle of a project & didn't want to start tinkering with things, being wary of the Murphy's law thing...
Thanks!

Cloud Class® Course: C++ 11 Fundamentals

This course will introduce you to C++ 11 and teach you about syntax fundamentals.

Server 2016 Standard with two running Hyper-V VM's. One running as the PDC and the other as the Exchange server. Months ago we had to turn off the original Exchange server because it was having problems and Dell didn't ship the operating system. To get exchange up and running  we installed a third VM using a trial version of Server 2016 Standard. This configuration has been running for months without any errors. To clarify VM's; 1. PDC, 2 Exchange (original), 3. Exchange2 (2016 trial version).

The VM running the trial version of Server 2016 (Exchange2) we want to power down and migrate the exchange server, or EDB to the original Exchange VM.

What is the best way to move the exchange server from one VM to the other? Ideally with the least or no downtime to end users? Is this possible?

As of now I've copied the EDB from Exchange2 and am thinking of using a tool to migrate this from EDB directly into the new server.

I keep getting the following error when creating a cluster on Hyper V

An error occured while creating the cluster and the nodes will be cleaned up.
Please wait...

There was an error cleaning up the cluster nodes. Use Clear-ClusterNode to manually clean up the nodes.

An error occurred creating cluster XXX-XXX-XX Cluster.


Patch levels and networking are all sound.

Hi guys,

We implement Skype for Business Cloud Connector on-premise  VMs on Hyper-V. (Building 1)
Also take a SIP Trunk from our ITSP in Building 2. There is some questions as below:
1-      Is it possible to forwarding SIP port from IP static in building 1 to IP static in Building2?
2-      How should I edit configuration.ini file? Specific in voice gateway section… put IP static that related to building 2 or what?
3-      Where should I use my SBC IP & IP address which I take with SIP Trunk modem
PS: Network structure and Configuration file is attached. Please help us in this regards ….
Thank you

Using Server 2016 Hyper-V, I'm comparing Dynamic vs. Fixed Disks using 10,000 RPM SAS drives and a Dell PERC H730.  
I have currently set all four partitions on the two VM's to dynamic disks but wondering if it is worth the effort to convert them all to fixed disks.
The partitions are all using VHDX files (two partitions for each VM--operating system and data for each).   According to this web page, dynamic disks are actually faster in "overwriting" than fixed disks so perhaps I should keep the disks to dynamic:

When trying to connect to a VM through Hyper V manager getting an error "An authentication error has occured (Code: 0x8009030e). Remote Computer : Server1.domain.local" and another error right after "Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator. Would you like to try connecting again?"
I can remote into the VM through RDP and i can connect to the host through another Hyper V manager and connect to the VM. Seems to be a UA issue on the host of that Vm. Any ideas?

Hi,

I am  new in SCVMM  ( hyper-v ) and comes from VMware background. i have  recently been tasked  to create to development server from critical running VM's  in cluster environment.  i have looked into this but cannot find snapshot operation the reason we are using System Centre 2012 Virtual machine manager where it only gives option for checkpoint.
 My question is  checkpoint is similar to snapshot and how  I can safely  create two development server using   Two live production VM's ,.
Please can any one expert on hyper-v en light  best way to achive this.


thanks

I have converted 3 Physical servers (server 2012 R2) to VMs using P2V program. I have now got all 3 VMs up and running in hyper-v (server 2016). I have created a virtual switch and  attached the VMs to it. It is configured as an external virtual switch so that the VMs can communicate with the rest of the network.

The problem is I cant ping anything. I cant even ping the hyerp-v hosts ip address?

I have created a fresh virtual switch and still nothing,

All the VMs are configured with static ip addresses.

Any ideas?

Azure has a changed a lot since it was originally introduce by adding new services and features. Do you know everything you need to about Azure? This course will teach you about the Azure App Service, monitoring and application insights, DevOps, and Team Services.

I have converted a server 2012 r2 device using Disk2VHD. The server had a c and a d drive so I converted them seperately.

I have now used the c drive vhd in hyper-v and it has booted up fine. However when I attach the d drive as a scsi hard drive to the vm, in blue screens during boot up.

Any suggesions on how to get this virtual server woking with a c and d drive?

We are assessing a server that has two virtual servers (SBS and a remote desktop server).  The host is running Win2008 R2 standard.  In the Hyper-V setup, there are two virtual switch.  One for each virtual server, SBS and the Remote desktop server.  Is this necessary or a misconfigurations?  From my understanding, we just need one virtual switch to accommodate both VMs correct?

Ideal small-business virtual environment.
Hello All. I was wondering if you guys could possibly tell me what the typical set of virtual servers you would expect to see on a well-implemented server 2016 Hyper-V host.
I can imagine that it would contain at least 1 DC/DNS server, a web server and an SQL server but what else should it contain?
 Should I have a file server?
Is there a backup appliance that will also handle the Android and IOS devices as well as the host?
I ave access to a copy of System Center- should I install a trial?
I plan on having a Plex and an Owncloud appliance.
Anything else?

Hi

I have a Server 2008 R2 guest running on a Server 2012R2 host.

I cannot get the integration services updated to the latest version which is causing me issues with my backup software.

The Hyper V manager is reporting "Integration Services: Update Required"

If i attach the integration services to the server and then install i get the following msg

1.JPG
If i upgrade it goes through successfully but after a reboot it still says that it needs an update and reports the same version if i try and install again.

All my other guest servers and up to date, however this is the only 2008R2 server all the others are 2012R2 or newer.

thanks
