Hi,
i plan to enable VM replication of this VM, but it stoped at initial replica, at last i canceled the initial replication.
but there are several checkpoints of initial replica left.i try to delete them, but there is no option, how can i delete these checkpoints of initial replica?

Need you help understanding how Hyper-V works...
There are 5 physical machines that are hosting Hyper-V, and each has 3 virtual environments running on them. The 5 machines are sitting within a Domain (Active Directory). So, as an administrator, if I want to access any virtual environment, is the login process described below correct?:
1. Input logon credentials on the physical host (authenticated by AD)
2. select virtual environment and then provide logon credentials (again authenticated by AD)
So, the questions here are:
1. Do the hosts inherit the password policies dictated by the Domain Controller (since they are within the Domain). Where am I able to see the settings that show Domain policies are being adopted?
2. Are the virtual environments also inheriting password policies dictated to them by the Domain Controller? Again, where am I able to see the settings that show Domain policies are being adopted?
I'm not a technical person, so please be kind!
Thanks for all your help...
The Copy Cluster Roles wizard did migrated the pass-through disks, Configuration files, CSV storage & VM to the target but fails to bring the VM configuration online/available at target cluster node (unable to power on the VM)

Hi all,
Having a bit of a nightmare with Hyper-V on my Windows 8 Pro laptop - Whenever I create a new VM and try to start it I receive the following error;
'Failed to start the virtual machine 'test' because one of the Hyper-V components is not running.'
I sometimes also receive an error saying something along the lines of 'Unable to change virtual machine state'
I have done a lot of searching a seen two common answers - The first is to try removing the Hyper-V role and re-adding it - I have tried this several times to no avail. (Intel VT and all virtualisation capabilities are enabled in BIOS). The second issue it would seem some people have had relates to editing the VMX configuration file and adding the linehypervisor.cpuid.v0 = "FALSE" - I thought VMX files were only present in VMware Virtual Machines...
Any help would be greatly appreciated.
Many thanks in advance.

Hi I have some dilemma whether it is a best practice or not to install Hyper-V role inside a physical domain controller and host virtual machines.
As well I am planning to host a two node SQL fail-over cluster in a virtual environment if it's a good practice to host a Hyper-V host in a domain controller MS2012R2 box.
Thank You
Hi,
we have setup a new server with Windows 2012 R2 and migrated our VM's over to it.
OS within the VM's are Windows 2008 Server, Windows 7 and Windows 2012.
Everything works fine. Integration Service Update was needed and I could install it on all VM's, except one, that also runs Exchange 2013 on a Windows 2012.
Once I install the Update of the Integration Service, the VM acts weird. It takes about 30 minutes until I could log in. (Probably network problem after the udpate). Once logged in, if I switch to desktop view, the task bar doesn't show items other than the clock, clicking it results in the question, if I want to end a hanging process no matter if I say yes/no no luck. Server Manager opens (very slow), but it doesn't load data (wanted to check nic).
CMD with ipconfig doesn't show a network adapter, just the tunneling-peudo-interface.
Load of the server doesn't show high CPU or Memory consumption, nor high disk i/o. Using Alt/TAB it shows a window called "Immersive Background" (tried to translate to english).
Starting the network manager via
control.exe /name Microsoft.NetworkAndSharingCenter
doesn't open it either. But I can open like Resourcemonitor, Powershell and quite some other programs.
So something is failing here after the update.
Does Exchange and the new Integration Service break each other?
I rolled back VM to an older snapshot and tried the same thing again, same result. On our Replication host, I did a Testfailover, with no network connectivity, everything fine, again, until new Integration service are installed/updated, the host seems broken.
So I have no clue what's happening here or where to start to search. The main problem is, that backups have to be done offline and not online until new integration services are up and running.
Any guess what to try or what breaks the new integration services? Or is it really in conjunction with Exchange?
We didn't upgrade the VM to 2012R2, just the root node.
Thanks

Hello
Activated the measurement feature in the Host to verify resources of a VM.
However when trying to verify the recuros with the Measure command, an error occurs.
Does anyone know what can it be?
Erro:
Object reference not set to an instance objectMCP - MCTS - MCTS AD
This happens on two Windows Server 2012 Standard machines. When they are rebooted none of the Hyper-V based virtual machines start on their own despite being set to do so. All of them are set to auto start at boot and all of them have to be manually started when the host is rebooted.
I've looked through all other settings and cannot find another place to change startup settings.
Note that I've set a startup delay on all VM's but that didn't seem to do the trick.Hyper-V could not replicate changes for virtual machine 'XXXXXXX': The requested operation cannot be performed on a file with a user-mapped section open. (0x800704C8).
I have seen this error discussed at length and the common culprit seems to be A/V. This is not the case for me. I got this error when checking replication health on a VM that fails replication almost daily. I usually resume it and it syncs data and continues to successfully replicate to the DR site until it fails a day or two later. Now, it won't resume. There is no A/V to blame and I am at a loss. I have a 5 node cluster on a san for my primary and a 3 node cluster on a san for my secondary. I have 43 VMs that replicate normally with very few failures. Not sure if this is any help, but we run BizTalk on this VM.

I'm trying to use external media as the initial seed for a Hyper-V Replica (Out-Of-Band Initial Replication). The replica job is created successfully, but when I try to complete the process (after shipping the media) the job is failing with the following error message:
A server error occurred while attempting to import the initial copy.
Hyper-V failed to import initial Replica.
Replication operation for virtual machine 'VM name' failed. (VM ID...)
Hyper-V failed to import initial replica for virtual machine 'VM Name': Account restrictions are preventing this user from signing in. For example: blank passwords aren't allowed, sign in times are limited, or a policy restriction has been enforced. (0x8007052F)
I'm creating a replica job from one Failover cluster (Forest A), to another failover cluster (Forest B). The sites have a site 2 site VPN configured and a forest trust configured.
Any assistance would be greatly appreciated!
Hi,
I am facing a massive problem with a Windows 2008 SP1 32bit server Virtual Machine.
The host is running Hyper-V 2012 R2 server (the free host with no GUI) and managed to P2V an existing physical server running Windows 2008 SP1 32bit using Disk2VHD.
The physical server has a parallel Sentinel SuperPro hardware security key and in Hyper-V I do not believe you can pass through parallel ports.
I read you can with USB.
Now the virtual machine fires up fine, but the financial application complains that it cannot detect the sentinel key and therefore it does not run.
I tried to emulate the dongle by using one of the dongle services websites.
The software runs fine just for one user, but it will not allow me to run multi-user.
So I have gone back to the web and found there are parallel to USB adapters, but I am not sure if they would do the trick.
I tried to contact Rainbow Technologies (dongle makers) in regards to this issue, but have had no reply thus far.
Has anyone been successful with this?
If so can someone give me some direction?
Thanks in advance
Best regards

I have a server running Server 2012 R2 Datacenter, fully patched.
Yesterday and today when trying to apply this month's Windows Updates to some Hyper-V clients, it is very slow. Both Windows 8.1 and Windows 10 clients that had all previous patches are taking several hours to download the updates.
One of the Windows 8.1 clients took from 10:00 to 17:30. We are on 80Mbps broadband and there was no significant other traffic, or loading on the server.
The internal network is 1Gbps and copying a 2GB .iso image to the Windows 10 VM runs at about 60MBps.
Howdy,
We've had a few instances where a VM that is set for Dynamic Memory would end up maxed out. We had one that came up yesterday and when I looked in Failover Cluster Manager the VM showed Memory Demand 2 Gigs, Assigned Memory 2 Gigs, Available Memory 0 MB.
The VM is set with 512 MB minimum and 16 Gigs Maximum but it wasn't working.
I simply Live Migrated the VM from one host to another and everything reset once it got to the new one and started working fine. We've seen this happen a few times in the past and Live Migrating always forced it to resolve itself.
Has anyone else seen this or know what might cause this? The Hosts are running 2012 or 2012R2 and so are the guests.
Thanks.
Hi,
When using Hyper-V Manager on the Node 2 of the Hyper-V Server and connect to manage Node 1, received this error:
