Hyper-V replica for a Windows 8 VM possible?

Hi,
I plan to maybe run 2 VMs on Hyper-V. Windows Server 2012 R2 Essentials and Windows 8.1 Pro. I plan to use a second server with hyper-V free on it. We'll make replicas on it.
I know I can use Hyper-V Replica to make a replica of the Windows Server VM every 5 minutes on the second server. Can we do the same for the Windows 8.1 Pro VM?
Also Can we use the Hyper-V server included with Windows Server 2012 R2 Essentials to replicate on a Hyper-V free server? Are they compatible? Or should we use 2 Hyper-v free servers so they are more compatible?

Hi ,
" Can we do the same for the Windows 8.1 Pro VM? "
I think you can replica the client VM to another hyper-v host on technical level .
But it may involve a licensing issue , for this configuration please contact to MS activation center for further assistance :

Hyper v replica for multiple sites

Hi
I support 3 sites and would like two of them running hyper v to replicate back to the same replica site and server. Is this possible to have two hyper v sites replicate back to the same server based at another location or do they require their
own individual replica server?
Thanks in advance
Shane

Let us take 3 sites: A, B, C.
1) A -> C and B -> C: this is a supported scenario. C is the replica site for primary site A and primary site B. This is typically a hoster scenario, where C is the hoster with A and B being the customers replicating to the hoster.
This is supported in Windows Server 2012 and Windows Server 2012 R2.
2) A -> B -> C: this is also supported, and is called "Extended Replication". Both B and C are replica sites. This is supported only if B and C are on Windows Server 2012 R2 (site A can be on Windows Server 2012).

Does Lync Server 2013 support Hyper-V Replica

I can’t find a definitive answer on this. I plan on either having 2 Standard Edition Lync 2013 Servers, or use Hyper-V replica for disaster recovery.
I’m expecting some down time during the failover. Looking for the simplest and most cost effective solution.

Hi,
It is not supported. Here are similar cases:

Question for "Hyper-V replica" and "replica server"

On the replica server, is it possible to have and operate other VMs, that are not replicas to existing VMs ?

Hello DimiterS,
Yes, sure you can run VM workloads on both Hyper-V hosts which are participating in Hyper-V Replica and vice versa.
For example, you can have DC01 on HV01 and DC02 on HV02 and then replicate DC01 to HV02 and DC02 to HV01.
No, you cannot have replication from Hyper-V 2012 to Hyper-V 2012 R2, you need to maintain the same Windows Server version on the physical host.
One advise, I would strongly recommend you to exclude the Paging File disk from replication, you can change the location of the System Page File inside the Guest OS to another disk/volume and then exclude it during the replication wizard, this will help
to reduce the replicated traffic and I/O since the paging files are constantly changing. More information
here.
Hope this help.

Hyper-V Replica Capacity Planner stuck getting VM information

I'm trying to use the Capacity Planner for Hyper-V replica tool to estimate requirements for a replica site.
It keeps getting stuck "Getting the VM and VHD from primary site, this can take upto several minutes...". I've waited over an hour, and it still sits there.
The primary site is a 3 node Hyper-V 2012R2 cluster. I have installed and configured the Hyper-V Replication Broker role on the cluster. For now, it's set to use HTTP without any certificates.
I don't have a replica site yet, so I've selected "Skip tests involving Replica site". For the primary site, I've tried pointing it at both the replication broker, and at one of the individual nodes. It gets stuck in the same place.
Other things I've tried:
Disabled windows firewall on all 3 nodes
Running the tool from one of the nodes, logged in as a domain admin account
Moving all the VMs off of one node, and pointing the tool at that now empty node
Let it run for longer - left it alone overnight.
Downloaded the tool again in case it was corrupt
Rebooted my computer
In all cases, it gets stuck at the exact same spot.
Any idea how to figure out why it is freezing? Have I missed configuring something important for the tool to run?

Hi Grant,
Thanks for your reply.
The tool and documentation have been updated for Windows Server 2012 R2
and can be download from here:

Would you please update it and see if it helps.

Hyper-V Replica Doesn't Seem to Replicate Expanded VHDX File?

I'm running Microsoft Windows Server 2012 R2 Essentials as a VM on Microsoft Hyper-V Server 2012 R2 (Server Core). I am using Hyper-V replica and extended replication to copy the Essentials VM to two backup Hyper-V servers. This has been working
for months.
This evening my 2 Tb VHDX used by Essentials VM was nearly out of space. I took down the VM and expanded the VHDX to 4 Tb. Then I restarted Essentials and used Disk Manager to allocate the new 2 Tb to give me a 4 Tb of space for Essentials to use.
The primary VM seems to be working normally.
But Hyper-V replication doesn't seem to be functioning correctly. I'm wondering if I'll need to delete the replication and start over since the size of the VHDX increased compared to the original configuration?
When I try and get replication to resume (from primary to secondary) I am prompted to resync which I have attempted many times. The primary creates a snapshot and then after a few moments the snapshot is merged back into the primary VM. But the VHDX on the
secondary still shows it is 2 Tb in size. So the resynchronization doesn't seem to have completed correctly? Plus I have the option to "Resume Replication" from the primary which also implies the prior resyncrhonization failed.
I haven't found any error messages using Server Manager to explain why the resync seems to fail.
At one point I found I was able to resync from the secondary to the tertiary server. I don't know what that actually accomplished, but both still have a 2 Tb VHDX instead of the 4 Tb that should now be available.
Any ideas on how to get replica and extended replica to work without having to delete and start replication over from the beginning?
Thanks for any assistance.
Theokrat

There was an error message that I'd overlooked and unfortunately this tells me I'll have to delete and restart replication from the beginning.
Cannot perform operation for virtual machine 'Windows Essentials 2012 R2' as virtual size of one or more virtual hard disks are different between primary and Replica servers. Delete and re-enable replication. (Virtual machine ID xxxxxxx)

Hyper-V Live Migration Compatibility with Hyper-V Replica/Hyper-V Recovery Manager

Hi,
Is Hyper-V Live Migration compatible with Hyper-V Replica/Hyper-V Recovery
Manager?
I have 2 Hyper-V clusters in my datacenter - both using CSVs on Fibre Channel arrays. These clusters where created and are managed using the same "System Center 2012 R2 VMM" installation. My goal it to eventually move one of these clusters to a remote
DR site. Both sites are connected/will be connected to each other through dark fibre.
I manually configured Hyper-V Replica in the Fail Over Cluster Manager on both clusters and started replicating some VMs using Hyper-V
Replica.
Now every time I attempt to use SCVMM to do a Live Migration of a VM that is protected using Hyper-V Replica to
another host within the same cluster,
the Migration VM Wizard gives me the following "Rating Explanation" error:
"The virtual machine virtual machine name which
requires Hyper-V Recovery Manager protection is going to be moved using the type "Live". This could break the recovery protection status of the virtual machine.
When I ignore the error and do the Live Migration anyway, the Live migration completes successfully with the info above. There doesn't seem to be any impact on the VM or it's replication.
When a Host Shuts-down or is put into maintenance, the VM Migrates successfully, again, with no noticeable impact on users or replication.
When I stop replication of the VM, the error goes away.
Initially, I thought this error was because I attempted to manually configure
the replication between both clusters using Hyper-V Replica in Failover Cluster Manager (instead of using Hyper-V Recovery Manager).
However, even after configuring and using Hyper-V Recovery Manager, I still get the same error. This error does not seem to have any impact on the high-availability of
my VM or on Replication of this VM. Live migrations still occur successfully and replication seems to carry on without any issues.
However, it now has me concern that Live Migration may one day occur and break replication of my VMs between both clusters.
I have searched, and searched and searched, and I cannot find any mention in official or un-official Microsoft channels, on the compatibility of these two features.
I know vMware vSphere replication and vMotion are compatible with each otherhttp://pubs.vmware.com/vsphere-55/index.jsp?topic=%2Fcom.vmware.vsphere.replication_admin.doc%2FGUID-8006BF58-6FA8-4F02-AFB9-A6AC5CD73021.html.
Please confirm to me: Are Hyper-V Live Migration and Hyper-V Replica compatible
with each other?
If they are, any link to further documentation on configuring these services so that they work in a fully supported manner will be highly appreciated.
D

This can be considered as a minor GUI bug.
Let me explain. Live Migration and Hyper-V Replica is supported on both Windows Server 2012 and 2012 R2 Hyper-V.
This is because we have the Hyper-V Replica Broker Role (in a cluster) that is able to detect, receive and keep track of the VMs and the synchronizations. The configuration related to VMs enabled with replications follows the VMs itself.
If you try to live migrate a VM within Failover Cluster Manager, you will not get any message at all. But VMM will (as you can see), give you an
error but it should rather be an informative message instead.
Intelligent placement (in VMM) is responsible for putting everything in your environment together to give you tips about where the VM best possible can run, and that is why we are seeing this message here.
I have personally reported this as a bug. I will check on this one and get back to this thread.
Update: just spoke to one of the PMs of HRM and they can confirm that live migration is supported - and should work in this context.
Please see this thread as well: http://social.msdn.microsoft.com/Forums/windowsazure/en-US/29163570-22a6-4da4-b309-21878aeb8ff8/hyperv-live-migration-compatibility-with-hyperv-replicahyperv-recovery-manager?forum=hypervrecovmgr

Server 2012: Enabling Hyper-V Replica Site to Site Failure

We recently installed Server 2012 Data Center with Hyper-V on a two servers at two different sites: Main Site and DR Site.
Hyper-V is enabled and working great at both sites on these servers and now trying to configure Hyper-V replica gets us this result:
Some of the items we made sure to verify:
Enabled Firewall rules for inbound rules on Port 80. (Hyper-V Replica HTTP Listener) (Both Sites)
Modified ASA Firewall for HTTP port 80 and can run a packet trace from site to site.
Ping works fine in communication between servers
Both are in the same domain
Within the same Trust Group
Same default storage location and can view the folder from each location
So I am not sure what we are missing, but is there another port that needs to be open if we are going through HTTP because after starting to configuring the replica another message shows that "Could not get the configuration details of the specified server."
Searching around on TechNet didn't show any resolution for this, but if anyone would have some additional tips to try to troubleshoot that would be greatly appreciated!
Thank you!

Hi All,
I am facing the same issue, Please let me the solution... I have given permission to user account at Local Groups in both nodes of Primary Site and DR Site.. and Windows Firewall is also off, IP Subnet is Different at both End...
Brief Description of Infrastructure.
We have Setup Windows Cluster 2012 Failover Cluster in Both Sites ( primary and DR) with the help of mentioned links.
http://www.thomasmaurer.ch/2012/07/hyper-v-replica-the-game-changer/
http://kristiannese.blogspot.in/2012/03/hyper-v-replica-by-example-part-one.html
Now, We want to cross-check Hyper-V Replica functionality but it is saying that Port 80 is not opened, Need Suggestion on same.
Windows Firewall inbound rules is already set as per above links.
Question: From where to where we need to open port 80 means which nodes/cluster/Hyper-V Broker ? As per mentioned cases.
Like,
Case 1. From Hyper-V broker of Primary Site to Hyper-V Broker of DR Site
Case 2: From Physical IP Address of Both Servers at Primary Site to Physical IP of Both Server at DR Site.
Case 3: From Cluster IP Address of Primary Site to Cluster IP of DR Site.
Case 4. From Physical IP Address of Primary Site to Hyper-v Replica Broker of DR Site.
Case 5. Port 80 need to open between Both End for Physical IP’s, Hyper-V Replica Broker and Cluster IP.
Kindly suggest on urgent basis.
Note: It is working fine in same IP Subnet, only change with different Subnet.
Please suggest from which IP to which IP , port 80 Need to be open in Mentioned scenerio.
Primary Site.
Host 1 IP address : 10.25.135.25
Host 2 IP address : 10.25.135.26
Cluster IP Address : 10.25.135.27

Hyper-V replica vs Shared Nothing Live Migration

Shared Nothing Live Migration allows to transport your VM over the WAN without shutting it down (how much time it takes on io intensive vm is another story)
  Hyper-V replica does not allow to perform the DR switch without shutdown operation on primary site VM !
why can't it take the VM live to the DR ?
that's because if we use Shared Nothing across the WAN, we don't use the data that Hyper-V replica can and then it also breaks everything hyper-V replica does.
Point is: how to take the VM to DR in running state, what is the best way to do that ?
Shahid Roofi

Hi Shahid,
Hyper-V Replica is designed as a DR technology, not as a technique to move VMs. It assumes that should you require it, the source VM would probably be offline and therefore you would be powering up the passive copy from a previous point in time
as its not a true synchronous replica copy. It does give you the added benefit to be able to run a planned failover which as you say, powers of the VM first, runs a final Sync then powers the new VM up. Obviously you cant have the duplicate copy of this VM
running all the time at the remote site, otherwise you would have a split brain situation for network traffic.
Like the live migration the shared nothing live migration is a technology aimed at moving a VM, but as you know offers the ability to do this without having shared storage and only requires a network connection. When initiated moves the whole
VM, well copies the virtual drive and memory before sending machine writes to both, then only to the new VM when they both match. With regards to the speed, I assume you have the SNLM setup to compress data before sending across the wire?
If you want a true live migration between remote sites, one way would be to have a SAN array between both sites synchronously replicating data, then stretch the Hyper-V cluster across both sites. Obviously this is a very expensive solution but perhaps
the perfect scenario.
Kind Regards

How to manage a Hyper-V 2012R2 Host from Windows 7?

AFAIK This is the official Hyper-V Manager for Windows 7: http://www.microsoft.com/en-us/download/details.aspx?id=7887 it explicitly lists Hyper-V versions up to 2008R2,
there is no mention of 2012 or 2012R2, and from trying to connect to my new Hyper-V 2012R2 I can confirm that it doesn't want to work.
From reading the docs on Hyper-V 2012/2012R2 remote management I've come to the conclusion that its only possible with Windows 8+ or Server 2012+ , but it cannot be used to manage Hyper-V 2008/2008R2...
Someone please tell me that this is just one big mistake on my part and that the product owner for Hyper-V at Microsoft is not this stupid...

Hi,
On Windows7 platform you can manage Hyper-V server under the 2008r2 versions.

Hyper-V replica over WAN

Hi,
Is there any formula/app for working out how many Hyper-V VM's can be replicated over a WAN connection.
I guess you need to take in to account:
WAN speed
Number of VM's to be replicated
Size of VMS
Number of replicas of each Server
Ect.
Cheers

Unplanned automatic failover using Hyper-v Replica , why don't the VMs start up automatically on the replica server?

Hi,
We have cluster with two hosts (Host01 , host02) replicated to another server (Replica01)
in order to test automatic failover to the replica server (Replica01) We unplugged the power cables from Host01 and Host 02
now the VMs on the replica server is still off , why don't the VMs start up automatically on the replica server?
Ramy Shaker

overall there is no automatic failover in Hyper-V
Of course there is. It's enabled by Failover Clustering. This is a totally separate technology from Hyper-V Replica.
There is no automatic start up in Hyper-V Replica because it is not designed to detect a split-brain condition where the same virtual machine is running in multiple locations simultaneously. The replica site has no way to know why it can't reach the primary
system anymore. It might just be because someone unplugged a network cable. If the primary's virtual machines are still running and the replica decides to spin up its copies, you will have many troubles.
