Is it possible to ask input of the user during deployment of the (linux) vm in scvmm?
In the guest OS profile, you can choose a new root password etc but i I want to add additional users to a linux vm during the deployment.

How to maximise screen (Windows 10 build 14352 hyper-v )
Hi,
I'm running the latest insider build of Windows 10, 14352 so this problem might be related to that.
The problem: I cant maximise or full-screen my vm. I'm running a lenovo laptop with 2540x1440 resolution (or something like that). When I start my Ubuntu 16.04 workstation, I expect to be able to maximise it so that I can actually see the letters on the screen. What happens is that the hyper-v "client" starts at around 1/4 of my screen estate (see pic), and no matter how many times I press the "maximise" button it doesn't scale beyond that. View--> Fullscreen just blacks out the rest of the screen, but the actual vm screen size is the same. There's no way for me in the VM display properties to change screen resolution either, since Hyper-V doesn't seem to report that to the VM.
I totally understand that Windows is the "priority one" OS for Hyper-V, but I was really hoping that Linux support was at least at level "useable".
What's the indended behavior here?

Move-VMStorage failing with error 0x80070005

PCI compliance: Audits
Hi,
I need to make an Hyper-v DSS PCI compliant, so I need to archive logs about any change or access to hyper-v from administrators. In Event logs I can find operations, but not the user that requested them (I think it's because a user asks for a change, then it's forwared to hyper-v from the parent partition, and the original user is lost). I tries an audit log to the VMs files, but it creates tons of logs from System user (replica updates, etc).
What is the right way to make Hyper-V DSS PCI compliant and retrieve rights audit logs?
thanks

Hyper-V with Simple Storage Space CSV
I'm looking for ways to improve the performance of our virtual machines, mainly through IO, because I believe that CPU, RAM and networking are pretty well taken care of. Ever since Server 2008 R2 with Hyper-V we've had issues with disk latency. Most of which was resolved by upgrading to 2012 R2 with the new CSV technology and SMB 3.0 backend. We're still seeing issues though, and I really need to track down what's causing it, because of VM performance isn't anywhere near where it should be.
We recently invested in a new SAN array, not just for virtualization, but it utilizes quad 8Gb controllers and currently has several shelves of disks (important to note they are all 7.2k, but striped heavily for increased read and write operations). I'm interested in testing this array to see how it compares, but I'm looking for suggestions on how to implement it properly. My main idea is to get several disks presented to our host nodes (most likely 2TB each), place them into a simple storage space (with no redundancy) and then use that storage space as a CSV for the Hyper-V cluster. I'm sure the SAN will allow the host to utilize all allocated space/IOPs for a specific LUN, but the host operating system will most likely not support channeling as many IOPs as we need into one LUN with FC overhead, processing power allocation to one LUN and so on. My feeling is this will help us by allowing the host to load balance the load across several disks, even if they are from the same array, hopefully helping it to utilize more available IOPs.
Any thoughts on this? Or even if it will work?

Hyper-V encountered an error while configuring network
Hey guys, a little help here
Hyper-V encountered an error trying to access an object on computer 'localhost' because the object was not found. The object might have been deleted, or you might not have the permission to perform the task. Verify that the Virtual Machine Management service on the computer is running. If the service is running, try to perform the task again by using Run as Administrator.
I checked and Hyper-V, VMMS is already running. Tried using both domain administrator and member server administrator account to create new virtual machine but still get the same error. Any idea what the problem may be?

Cannot add Intel Associated network card to virtual network
Hi,
The problem happens on Hyper-V installed on a Windows 2008 Datacenter Core installation.
This server has 2 NICs + 2 Dual Port NICs that are teamed 2 by 2 using Intel ProSet and drivers utilities (Switch Fault Tolerance).
Configuration is OK on the host and networks works fine.
The problem is that when I try to use the NIC associations in a virtual network I get the following errors :
Using Virtual Machine Manager :
Unknown error (0x8005)
Using Hyper-V Manager MMC Snap-in :
"Echec du commutateur d'installation. Le commutateur n'a pas pu se lier à ... car il est déjà lié à un autre commutateur."
(Switch installation failure. The switch cannot link to ... because it is already linked to another switch"
Note that there is no existing virtual network when I proceed ...
Must I anderstand that there is absolutly no way to get switch redondancy to work with Hyper-V ??

How to remove a VEthernet virtual switch from a NIC Team
Hi and thanks for reading. How do I remove or delete a vswitch from a team (not from a vm) or do I have to delete the Nic team?
I seem to only be able to find powershell cmds to delete or remove from a VMachine.
If you can help please can you post the actual cmd to delete\remove any of the vswitch as shown in the image.
Any help much appreciated.

Unfortunately, on the next start after a reboot I get an error:
We couldn't complete the features

Don't turn off your computer.
Any clue on how to get the Hyper-V removed?

"we couldn't complete the features undoing changes" on activating Hyper-V
I've been looking for this error all over the internet, and I can't find any solution.
So I have a Asus N750JK with Windows 8.1 64 bits Pro installed.
I have SLAT feature (I downloaded a small application to check and it says I have it all) , I also have activated Intel Virtualization in the BIOS. When I go to Control Panel -> Programs -> Enable or disable Windows Features, I go to Hyper V and check"Hyper V Platform" , it applies the updates, asks to restart computer, and it does, then it goes normally, starts to update, restarts the windows and it goes up to 100% and in the end it says: "We couldn't complete the features undoing changes" and restarts my windows once again and says: "we couldn't complete the updates undoing changes"
I have tried:
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
but nothing changed.
What do I have to do to fix this?
Thanks.

We have configured Hyper V clustering with Windows 2012 R2 DC. All the disks are configured as CSV, later installed guest OS and applications and everything is working fine as of now. Now most of teh CSV are showing the information Chkdsk scan needed. We are looking for a solution to correct this / run Chkdsk on CSVs and if required how frequently do we need to run chkdsk on CSVs

Cannot connect to virtual machine
I am running a Server 2008 R2 as a host server for Server 2008 R2 virtual machine. I have the following error in the Hyper-v Worker event log: failure in machine remoting system. Error: 'Unspecified error' (0x80004005). If I open the Hyper-V manager, I get the following message:Cannot connect to virtual machine.
Most of the research I have seen, it says that there is a certificate expired problem, but the certificate in question does not expire until July 28 2016. I remember getting a warning last year that the certificate was going to expire, but it renewed automatically. Any answers to this problem.

I'm facing a issue with the Hyper-V Virtual Machine Connection running on Windows 10 Enterprise version 1511.
When I switch windows from a full screen virtual machine connection to another application, the virtual machine window resizes and exits the full screen mode. The resolution is not affected though.
Is there a way to change this back?

Server OS: Windows Server 2012 R2
I have a VM Gen2 with following settings:
I can boot fine from the same .iso from a Gen1 VM so the .iso is bootable.
I know that the Gen2 VM uses SCSI instead of IDE, but I have no clue regarding how to boot from the .iso..

vmconnect.exe FROM Windows 7 TO Hyper-V 2012 R2?
Hi,
I am trying to remotely administrate a Hyper-V Core 2012 R2 Server using a Windows 7 client.
As I understand it, this is not possible using the Hyper-V Manager because the Server and client versions are incomaptible?
However, I'd like to know if I should be able to connect to a guest-VM on said Hyper-V Server from my Windows 7 client using the "vmconnect.exe"?
Or is this also not possible due to the different Versions?
Thanks in advance for the info!

Problem communicating over vNICs
I am implementing a Hyper-V converged network (4 cluster nodes), however having an communications issue on the vNICs connected to my management switch.
The same issue on all 4 nodes. If anyone has any suggestions, I would appreciate it.
Each host has the following
- 8 physical NICS (NIC1-NIC8)
- NIC1 –a temporary management of IP of vLAN151
- NIC4 - spare
2 Teams (Configuration below)
- ManagementTeam – NIC6/7
- VirtualMachineTeam – NIC2/3/5/8
2 Virtual Switches
- Management Switch – 3 virtual NICs created for Management (vLAN151), Live Migration (vLAN152) & CSV traffic (vLAN153)
- Virtual Team Switch – no virtual NICs
1 Physical Switch Stack
- NICs 6/7 – ports trunked, vLAN 151, 152, 153 permitted
- NICs 2/3/5/8 – ports trunked, vLAN 400, 800, 71 permitted
I ran the following attached PS commands (without any errors) to create & configure Teams, Virtual Switches, Virtual NICs – per host.

Get-NetAdapter -Name "vEthernet (LM)" | New-NetIPAddress -IPAddress 172.16.152.5 -Prefixlength 24
Note - Cluster Node 1 has following IPs presented to the ManagementOS

"vEthernet (Management)" - 172.16.151.5/24 -Defaultgateway 172.16.151.1
"vEthernet (CSV)" - 172.16.153.5/24
"vEthernet (LM)" - 172.16.152.5/24
Some of the testing results:
Ping 172.16.151.1 – Works Fine – Note, the system using the temp management IP 172.16.151.55 as the source
Ping 172.16.151.5 –S 172.16.151.5 – works fine
Ping 172.16.152.5 –S 172.16.152.5 – works fine
Ping 172.16.153.5 –S 172.16.153.5 – works fine
Ping 172.16.151.1 –S 172.16.151.5 – FAILS - so unable to ping the Default Gateway using
"vEthernet (Management)" as source IP.
Conclusion
Therefore it seems I can’t pass any traffic via the Virtual NICS & Management Virtual Switch. The physical Network Teams look ok. All the ports on the physical switch stack are UP.
Phyiscal ports are trunked and required vLANs permitted
