Windows Server 2012 Hyper-V Replica general access denied error

Good morning:

I am seeing a "General access denied" error when attempting to replicate a VM from an on-site 2012 cluster to an off-site 2012 cluster.  Both clusters are Hyper-V 2012, each with their own Replica Broker configured.  Each broker configuration uses Kerberos, constrained delegation (configured to allow each locations hosts to be source and destination on the other), and a unique CSV storage path at each site.  When I right-click a VM and enable replication (from our primary site/cluster), I type the hostname of the replica broker for the destination site, ensure Kerberos port 80, compression enabled, select the VHDXs to replicate, use only the latest recovery point, begin immediately, send over network, and receive the following message:

Enabling replication failed.  Hyper-V failed to enable replication.  Hyper-V failed to enable replication for virtual machine 'virtual machine': General access denied error (0X80070005). (Virtual Machine ID unique ID).

What is very weird is that replication works in the opposite direction.  That is, from our secondary site to our primary site.  I can see the replication progress in Hyper-V Manager on that VM's host.

Hello. I have just enabled Hyper-V on my Windows 8.1 laptop.
Dell Latitude E7440 i7-4600U @ 2.10GHz
I can create a Virtual-Switch but I am unable to create a new Hard Disk or Virtual Machine within Hyper-V. I get the same error for both processes.

Error: The Virtual Machine Management Service encountered an error while configuring the hard disk on virtual machine New Virtual Machine.
Failed to create the virtual hard disk.
The system failed to create C:\Users\user\Documents\Test\New.vhdx .
Failed to create the virtual hard disk
The system failed to create C:\Users\user\Documents\Test\New.vhdx . A Virtual disk support provider for the specified file was not found. (0xC03A0014).
I have ran all Dell Client System updates and all of windows updates.
I have attempted to create a virtual machine on the current SSD and also an external drive. The same error appears.
I have also attempted to create a virtual hard disk via Hyper-v with a Base vhdx, still the same error occurs. I've tested the base image on other laptops of the same model and windows 8.1 without issue.
Any thoughts on how I can fix this?

Thank you,

Hello, here is my hardware for my Hyper-V host that will be running 4 VM's for 20 users and may max out at 30 - 35 users in the future:

PowerEdge R520
2 -Intel Xeon E5-2420 v2 2.20GHz (24 Total Cores)
64GB RDIMM, 1600MT/s, Low Volt, Dual Rank, x4 Data Width
300GB Raid 1 for the Hyper-V Host (2 -300GB 15k SAS Drives)
1.6TB Raid 5 for the VMs (4 - 600GB 15k SAS Drives)
4 - 1GB NICs (1 NIC for the Host and 3 Teamed NICs for the VMs)

The VM's I will be running (All will be running Windows 2012 R2 Standard GUI):

1 - Domain Controller (Active Directory, DNS, DHCP and File Sharing)
2 - Backup Domain Controller (Active Directory, DNS)
3 - Microsoft SQL 2012 Standard possably 2014 and Microsoft Dynamics GP
4 - Remote Desktop Server - 5 to 10 users (Running Office 2013, Microsoft Dynamics GP Client)

I know this is not an exact science but was looking for a safe configuration to start out with and will tweak once it is in production.  This was just a guess on how I was going to start out:

1 - Domain Controller
CPU 6 Cores
12GB Memory not Dynamic
60GB VHDX Fixed Size, I will also create VHDX Fixed Disk for my Data

2 - Backup Domain Controller
CPU 2 Cores
4GB Memory not Dynamic
60GB VHDX Fixed Size

3 - Microsoft SQL
CPU 8 Cores
32GB Memory not Dynamic
60GB VHDX Fixed Size, I will also create VHDX Fixed Disk for my SQL Data

4 - Remote Desktop Server
CPU 6 Cores
8GB Memory not Dynamic
120GB VHDX Fixed Size

Server 2012 VM stuck on "Please Wait" during boot up

I am running Server 2008 R2 with Hyper-V. All virtual machines are stored on an iSCSI SAN. I have three host servers in a failover cluster.

Yesterday, one of my host machines failed and shut down unexpectedly. Failover occured as expected but the machines which were on that host were shut down uncleanly. One of them was a VM running Server 2012 which runs SCCM 2012.

I got the failed host machine back online and spread my VMs out over the 3 servers again. At this point I had not started my 2012 VM back up.

I tried to boot my server 2012 VM today and it has been stuck on a dark blue server 2012 screen with Please Wait and a spinning circle for 45 minutes at the time of writing this post.

I don't know what's happened to this machine - or why it is stuck. It was shut down cleanly yesterday when the failure occurred. Is there anything I can do to get this VM up and running again?

Edit:

It finally finished booting so I could log on. It took an hour and 6 minutes to get to the login screen. If anyone has any ideas why this might have taken so long (all other VMs are fine and boot quickly) and how to prevent it from happening in the future, I'm all ears!

It's now taking a while to actually login, mind you... stuck on applying user settings... so presumably there's still a problem somewhere.

2 out of 3 nodes lost connectivity during backup, not all VMs restarted

we have DPM 2012 SP1 backup to VMs on a 3-node Windows Server 2012 R2 SP1 Hyper-V cluster directly to tape for so many months without issues.

However, this month we had a very sad scenario.

The backup starts at 12:00 AM, at around 3:30 AM VMs on two nodes out of 3 failed due to being unable to access storage.

We get events about virtual machine configuration not available for all VMs hosted on these two nodes. After less than two minutes we get events that the VM configuration is again accessible.

during the two minutes of failure, 5 VMs were reported in event viewer as degraded on both nodes. these 5 VMs stayed down after the configuration became accessible.

other VMs on both nodes restarted unexpectedly, however, one 2003 server VM showed Boot failure and another XP VM showed Blue Screen 0xF4

When we arrived on site at 5:00 AM, we started the 5 degraded VMs without issues, and resetting the 2003 and XP VMs worked also.

However, we found the CSV in redirected access for backup, and backup was still running. needless to say the VMs were very slow.

stopping the backup restored the CSV to the online state.

any insights about the cause of this trouble!

PS. we are planning to restart all the nodes and DPM server and try the backup again to see how it goes.

Hi I am trying to find the best way to migrate from ESXi to Hyper-V with Server 2003 DC with two hard drives. I know I should not snapshot the DC so I guess what's the best way to do this. Here is the one catch I only have on physical host. 

Should I uninstall the VMware tools, shutdown all my servers, export the vm to an OVF, uninstall ESXI, install HyperV, convert the OVF to use with HyperV, import the machine and than boot up?

BOOTING OPERATING SYSTEMS FROM VIRTUAL MASCHINES (WITH BCDEDIT.EXE)

HELLO MICRO SOFTY,

RECENTLY IN WINDOWS SERVER 2012 AND WINDOWS 8 MICROSOFT ADDED BETTER SUPPORT FOR VIRTUAL MACHINES.

NOW IT IS POSSIBLE TO BOOT THE COMPUTER INTO VIRTUAL MACHINE.

YOU SHOULD USE BCDEDIT TO EDIT BOOT STORE DATA CONFIGURATION, AND THAT IS IT.

BUT I HAVE A QUESTION.

THIS WORKS FOR A NEW OPERATING SYSTEMS.

I NOTICED THAT ALL BOOT ENTRIES HAS ITS PATH TO BOOT FILE. WINDOWS 5 (XP, SERVER 2003), HAS PATH C:\NTLDR, AND WINDOWS 6 (VISTA, SERVER 2008, SERVER 2012, 7 AND 8) HAS PATH C:\WINDOWS\SYSTEM32\WINLOAD.EXE.

I FIGURED OUT, IF I USE VIRTUAL MACHINE HARD DISK FILE, THAT I COULD JUST TYPE THE PATH TO THE OS LOADER, AND THAT IT WOULD WORK.

I TRIED THIS WITH MS-DOS 4 AND ITS OS LOADER IO.SYS.

BUT WINDOWS 8 BOOT MANAGER, WHEN I SELECT MS-DOS FROM BOOT MENU SAYS THAT IO.SYS IS MISSING.

BUT IO.SYS IS IN THE ROOT OF THE VIRTUAL MACHINE FILE, AND VIRTUAL MACHINE (HYPER-V) BOOTS INTO DOS NORMALY.

SO, WHAT IS WRONG WITH MY IDEA?

IS IT POSSIBLE TO BOOT PRE-VINDOWS SYSTEMS AT ALL USING WINDOWS 8 (ACCTUALLY WINDOWS 6) BOOT MANAGER, AND HOW TO CONFIGURE BOOT MANAGER TO USE IO.SYS AS A BOOTLOADER?

IS IT ENOUFF TO JUST COPY WINDOWS XP BOOT ENTRY AND EDIT ITS SETTINGS TO INCLUDE VHD FILE AND TYPE A PATH TO THE IO.SYS, OR, DO I NEED TO PERFORM ADDITIONAL CONFIGURATION?

IT WOULD BE COOL TO USE WINDOWS 8 BOOT MANAGER TO BOOT INTO DOS.

SUGGESTIONS?

THANXY. ;)

Hi All,

Does anyone know of any up to date guide for setting up a Hyper-V Home Lab? I intend on setting one up to do testing and development. It will need to run SharePoint 2013.

I want to quickly be able to use *.ps1 scripts to spin-up new SharePoint VMs for testing.

What I'm looking for is recommendations on hardware, configuration, etc. For example how many physical servers do I need?

Thanks!

Hyper-V 2012 R2 Gen 2 VM failed to boot from SCSI DVD drive using ISO image file

Hello:

I'm having a problem trying to install Windows 8.1 Professional on a new Gen 2 VM. I created a new Gen 2 VM using Hyper-V Manager running on Windows Server 2012 R2 and then told it to boot off DVD drive which pionts to the ISO file that I copied to the E: drive.  The ISO file mounted in the virtual DVD drive is the Windows 8.1 Professional x64 VL ISO that I downloaded off of TechNet. When I start up the VM to install the OS, I receive this error:

"Synthetic SCSI Controller (Instance ID 7512B228-F7BC-4DD8-B4F4-72A5B042C2E9): Failed to Power on with Error 'The file or directory is corrupted and unreadable.' (0x80070570). (Virtual machine ID 4195A398-3531-4A34-8588-D1FC3F3DD2D4)"

Basically the SCSI controller can't read the ISO file. However, the IDE controller on a Gen1 VM can read and boot from the ISO just fine. Has anyone else run into this problem? Is there a way to resolve this issue and allow me to boot the ISO from a SCSI controller?

Or is there a bug with the Hyper-V SCSI controller that makes it unable to boot from ISOs properly?

I've got two machines,

Windows Server 2008 R2 Enterprise

Windows Server 2012 R2 Datacenter

Assuming everything is correctly set up in terms of connectivity and the Hyper-V Management agent service, is there a known compatibility issue with remote management through Hyper-V Manager from 2008 R2 to 2012 R2?

2012 to 2012 R2 works correctly

2008 R2 to 2012 works correctly

But 2008 R2 to 2012 R2 on ANY 2012 R2 machines does not work correctly.

Anyone have any idea what's going on?

Packets from physical network not forwarded to Network Bridge (Hyper-V 3.0)

I am running a test lab on my Windows 8.1 using Hyper-V.

My problem is, that the virtual LAN has limited connectivity, when the external vSwitch is configured to use the wifi interface, instead of the cable interface. I am troubleshooting this issue for hours now and I reached the point where I believe the Network Bridge, that is created by the Hyper-V Virtual Switch Manager, is not forwarding packets.

Pings are delivered from 192.168.178.2 to 192.168.178.1 and back again.

Pings from 192.168.0.10 are delivered to 192.168.178.1, and the reply does reach the wifi interface …

== Trace on the WiFi interface ==
Here you see a log of the trace on the WiFi interface of the Hyper-V-Host,

Hyper-V. Resource aggregation. Resource pool.

Hello, everyone,

I have a question to Technet community. Hopefully, someone will be able to help.

We’re in the process of building a new Hyper-V environment, and the interesting question has arisen once again.

Is there any way to compartmentalize all resources in a host or a cluster? For instance, create resource aggregations as direct children of the host or cluster and configure them and then delegate control over these entities to other individuals or organizations?

VMware is using “resource pool” concept for the same purpose (illustrated above), but as far as I know Hyper-V “resource pools” aren’t the same, being used mostly for billing purposes.

Is the SCVMM with its “private cloud” mechanism the last resort? Or may be I’m looking in wrongdirection here? 

Kind regards, Leonardo.

[Forum FAQ] Receive Side Scaling and Virtual Machine Queues Quick Start

July 7, 2014, 8:43 am
$

Quick Review

  • RSS is Receive Side Scaling and is a commonly used technology to disperse network traffic among multiple CPU cores on a physical host to load balance processing.  Reliant on vendor implementation. RSS was first implemented with the scalable networking pack in 2003 SP2 and is still widely used today.
  • VMQ is Virtual Machine Queuing and is a commonly used technology to evenly disperse network traffic among multiple CPU cores on virtual machines on a Hyper-V host. Reliant on vendor implementation.
  • VRSS is VIRTUAL Receive Side Scaling and can be used to augment VMQ on VMs to increase throughput. VRSS is introduced in 2012 R2 and you must use 2012 R2 level OS for both the HOST and the VM.
  • VMQ Queues are maximum numbers of lanes (processor allocations) at a hardware level.
  • RSS Queues are maximum numbers of lanes (processor allocations) at a hardware level.
  • SR-IOV is another technology that can be paired with VMQ.

I have setup hyper-v server 2012 on my server. there is only 1 VM running with 4 GB ram & 1.5 TB expanding hard drive.

I have found error in guest os "disk 1 has been surprise removed"can any one tell me what is this error exactly.  after this error i have checked hyper-v manager & found machine is showing"Merge In Progress" 

i never saw "disk 1 has been surprise removed"error. is this error occur because of hyper-v server is not configured properly.

Also i have server 2008 R2 DC x64 which is working as hyper-v host. I have checked event logs of same and found following error."The disk signature of disk 2 is equal to the disk signature of disk 1."what is this.
