How do I replicate to a server that already has a copy of the VM Guests?

Hello,

I have two servers at two different locations.   The internet speed would have taken forever to do an initial sync of all the VMS.   I have the VHDX files and VMs on both the production and the replica server.    I have no idea
how to do a sync if the data is already on the second server - just a day apart.

hyper-v windows 2012 R2 – Move VM from one drive to another drive on the same Hyper-v server questions?

Dears,

I have two Hyper-V servers windows 2012 R2 (one is primary & other is Secondary)

- on primary hyperv- i have two virtual machines -a) DC server, b) SQL server

- Replication enabled for only one Virtual machine i.e."SQL server" between two hyperv server (primary & secondary)

- disk space becoming full on VM - SQL server, so we are adding more sas drives with new raid-5 configure

- After add disk i want to move this VM -SQL server to this new disk so will have more space.

- Need to know the correct procedure/steps for move this VM -"SQL server" & if need to take any precaution if it fails because     this SQL server is my business production server.

- Do I need to make any folder as share on new disk?, Do i need to have enough on the existing disk (my SQL server is around 400 GB but I have left space only 60GB free)?,

I want to take full precaution because as i said this is my production server.

- In my knowledge first I would need to pause replication, than stop virtual machine, detach any scsi drives from VM (i have external hdd attached for regular backup), then use MOVE command for Hyperv manager.

What is this bitmap image on my desktop and why did it appear the first time I logged in with hyper v enabled?

I am running a w10 pro, I have every setting turned on in windows features that mention hyper v, I also have ‘guarded host’ set to on. I have Virtualization Technology, Virtualization Direct I/O  and the (VMM) container image manager in the bios,
the TPM enabled and the disk is encrypted with bitlocker. The Nic with pxe is on but the pxe is disabled presently, When I boot the machine it has a bitmap image on the desktop and the display resolution is set to 640×480. I have to reset it each time! What
gives? Are the hyper v and the bitmap image related somehow? I tried to put it in the recycle bin several times but it always snaps back into place. Currently the one drive has sucked it up and made a digital copy of it. Is this some sort of virus? Is there
some way I can delete it and/ or should I?

AD dependency of Hyper-V 2016 Cluster

Hi!

We currently have multiple Hyper-V 2016 clusters running in our company, all with SAN luns connected.

This morning it seems we have had a technical issue on storage level which still has to be figured out.

From 6:37:29 till 6:37:35 all our luns, on all our clusters and nodes reported following event (5120):

Cluster Shared Volume 'LUNNAME' ('LUNNAME') has entered a paused state because of

'STATUS_CONNECTION_DISCONNECTED(c000020c)'. All I/O will temporarily be queued until a path to the volume is reestablished.

After the connection to every lun was lost, we received the following critical event (1135), again from every node. 

Cluster node '99-001-203-s052' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node

having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network

adapters on this node. Also check for failures in any other network components to which the node is connected

such as hubs, switches, or bridges.

And finally - logically - followed by (1177):

The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the

cluster, or a failover of the witness disk. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network

adapter. Also check for failures in any other network components to which the node is connected

such as hubs, switches, or bridges.

However, since no network related events were found I do not understand why the cluster nodes went down after losing their storage. The only possible explanation for this behavior is a loss of authentication towards the domain controllers.

We have 2 physical and 2 virtual DC’s, so this would mean that at this point all of the Hyper-V Hosts (32 hosts spread over 5 clusters) were authenticated to the virtual DC’s and did not manage to re-authenticate to a physical one in a timely manner.

Moreover, it was in my understanding that combined use of  Network Service & CLIUSR account drastically reduced (negated?) the necessity of available DC’s to stay online in case of emergency

Can anybody shed some light on this situation?

Cannot Delete Checkpoint

My Hyper-V host is Server 2012 R2.  I have a virtual machine (Server 2012 R2) that has a checkpoint.  When I right-click the checkpoint, there is not the option "Delete checkpoint…".  I need to delete this checkpoint so that
it merges with the parent VHDX.  What is the best method for doing this?  I’ve researched and found where people have exported the checkpoint so that it merges disks, exports the entire VM, and then you import as a new VM.  I don’t like this
option since I will be creating a new VM and I don’t know how the applications on the server will react to that because I’ve read that the VM will see it as a hardware change.  I’ve also read about doing a manual merge of the disks by clicking on the
‘Edit Disk’ button in Hyper-V Manager.  But this has been under the condition of creating another VM.  Is it possible to merge disks while still connected to a VM?

Is it possible to move VMRS files to a different drive?

We built a Windows 2016 Hyper-V host with 150GB spaces on C drive. Now, it is low spaces. Is it possible to move VMRS files to a different drive?

Hyper-V on VPS with one NIC – Help with setup due to nothing working

Hello, This might seem like a noob-ish question to many of you but here goes anyway.

Over the past week i have been trying to setup hyper-v on my VPS. It has one Static IP and one NIC.

I seem to be unable to actually link the internet connection from my NIC to my VM environment.

Is someone able to shed some light onto this for me as i have exhausted all ideas and every link on google now.

EDIT: Further information that might help you help me: 
I have tried sharing the internet connection from my NIC to an internal switch, Sharing via Hyper-V to a physical adaptor. So i have tried an internal and physical/external adaptor.

I am on windows server 2016

Kind regards

Titch
