Grouping two server together on same Host.

$

0

In the Hyper configuration that is setup it has 7 hosts each with several guest servers.

I have two servers that I would like to keep together.  So if HYPERV-SRV01 is placed into maintenance mode I would like to have guest-server01 and guest-server02 move together to another Hyper-v host (HYPERV-SRV02).  All of these host are in the same blade server chasse.


Hyper-V - Replica - Initial replication stopping

$

Hi

i have setup 2 Hyper-V host's with local storage. 
network between the servers: 1gb (i monitor the traffic on the switches, and the 1gb connection is not fully utilized so bandwidth should not be a issue.)
storage 12x5tb  RAID6

host are in the same domain, and replication with Kerberos is enabled on the destination host.

I have setup replication of a big file server (18tb),  there is no changes on the file server during the initial replication.

i get these events on the source


on the destination host:

Hyper-V failed to apply changes on target for virtual machine 'SERVERA'. Possible reasons are loss of network connection with the primary, the replication was suspended or cancelled on the primary: An unexpected network error occurred. (0x8007003B). (Virtual machine ID 427D4FCC-FA8A-4245-8CCD-8CCB2FB4BE0F)

After this i have to resume replication, seems to work, but the replication have stopped 5 times, and i still have 9tb left to replicate.

Any ideas?






Cannot start imported Hyper-V VM: The Security ID structure is invalid (0x80070539).

I haven't seen any mention of this in any of the forums. I'm attempting to import a virtual machine to a Server 2012 R2 Hyper-V system. Normally this is fairly straight-forward. However, the imported virtual machine will not start. I'm getting the following error message:

[Window Title]
Hyper-V Manager

[Main Instruction]
An error occurred while attempting to start the selected virtual machine(s).

[Content]
'Unnamed VM' could not initialize.

An attempt to read or update virtual machine configuration failed.

I'm not familiar with what is going on here. Any ideas?

Thank you.

VMs network speed 2

Hello!

Consider the following testing environment: there're two host machines - HOST1 and HOST2 - (Core i5, 16Gb RAM, 3 Nics, one of the nics -HV - is used for test VMs) that host one VM each (now they are "DC" and "EXCH1"). These VMs are connected by the 5-port 1Gb switch UPVEIL.

All operating systems (both for host and virtual machines) are Windows Server 2012R2.



To make sure VM1 can communicate with VM2 I run on VM1 "ping VM2 -t" - there would be NO any packet loss however many minutes/hours thisping continues.

When any action starts that require a bit more network traffic to pass from VM1 to VM2 or vice versa (copying files, connecting to the other VM's Computer Management console...) the network communication stops after several seconds:

After some timeout it resumes and the process of stopping/resuming may be repeated several times or the operation may never be completed at all.

Exactly the same Nics and switch operate perfect when connecting HOSTs (NOT the VMs) - the problem arises ONLY between VMs (Hyper-V).

I did this test many times with different Nics and different switches - no problems exist until the Nics start to get used by Hyper-V.

???

Thank you in advance,

Michael


Hyper-V Replica in a workgroup environment

$

I'm trying to set up Hyper-V Replica between two Windows 2012 R2 hosts.   They are not part of a domain, but they do belong to the same workgroup.

On the secondary host, I enabled it as a Replica server and selected Kerberos for the authentication mode.  I also selected "Allow replication from any authenticated server".  I then ran the Enable Replication wizard on the primary server and went through the wizard.  After clicking Finish, I get a "Enabling replication failed" error dialog with this message:

     Hyper-V failed to enable replication.

     Hyper-V failed to authenticate using Kerberos authentication.

     Hyper-V failed to enable replication for virtual machine 'xxx': No credentials are available in the security package (0x8009030E).

    Hyper-V failed to authenticate the Replication server YYY using Kerberos authentication.  Error: No credentials are available in the security package (0x8009030E).

The one post I found that talked about this issue in a workgroup environment, http://www.chicagotech.net/win8&2012/replicaissue1.htm, suggested making sure that Everyone and Authenticated Users have permission to "Access this computer from the network" in local policies.  Did that on both machine and that didn't help.

Does anyone have any other suggestions?

Thanks,

Richard

Hi I have a strange error which I could do with some input on and wondered if anyone knew of this.

I have a HyperV 2012 R2 Server with an Guest VM running Windows 2003. Whenever I try to backup this VM I am seeing the following event in my Hyper V Server

Now the file mention doesnt exist, it doesnt have any snapshots. Other VMs are fine.  I have migrated the VM to another server - and get the same issue on that server.

The server works fine and starts up.  I have seen other reports mentioning check the permissions on the file/folder to make sure the Machine ID has permissions - it does.  I have changed the status of the Fsdepends registry key as i've also seen - makes no difference.  I just cannot get rid of this error.  I have opened the machine config XML file and there is no mention of it there.

My last resort is to create a new VM and use the same disks.

The only difference between this and other VMs on that server is that this is an old Legacy 2003 box.

I am stumped any ideas?  Thanks in advance

DC on a Hyper-V cluster

Hi there,

I have a 2 node Server 2012R2 Hyper-V cluster and a stand alone Hyper-V 2012R2 host. I have one virtualized DC on the standalone host and one on the cluster as a highly available VM. Can someone please advise if I need to assign static mac addresses to the nics on the virtualized DCs. Some people seem to say yes and other that there is no need to. If the answer is yes, then what would be the best way to go about it given that the DCs are already virtualized? My concern is that if the Mac address changes, will it affect AD in any way. 

Thanks very much,

Single license of WS 2012 OLP, then downgrade to WS2008 R2 with 2003 SP2 on hyper-V VM?

$

Hi,

I'm seeking an answer, that if I purchase WS 2012 Standard OLP. Then downgrade it to 2008R2 and install into a physical server. I understand that one WS2008 R2 is ok to have one VM running Hyper-V. In my case I would like to run 2003 SP2 on hyper-V which is using Virtual Key from this single license.

My question is, do I need two licenses? Or single license is enough?

My requirement initially is, there is one apps that still need to run on WS 2003, but Dell R730 does not support WS 2003 anymore. So Hyper-V is a plain solution that I can thinking off.

Hyper-V Network Configuration Problem - Virtual Switch

$

Hi guys,

I'm looking for some help with a Hyper-V Network issues. I have been handed over a project by a client that is not fully complete and the person who built it is not available at all. The setup is a HP C7000 blade chassis and a HP SAN.

The previous guy built a hyper-v cluster with 2 nodes; HV1 & HV2 - this works fine, I can live migrate etc and all is good.

This is how it was handed over to myself, my job is to add the third node to the cluster so I have installed the OS, drivers etc. Hyper-V role and clustering role. My problem arises with the Hyper-V switch configuration.

Points;

  • Each node has two NIC adapters, both of these network adapters are teamed
  • A virtual switch is created on each node using the aforementioned NIC Team
  • On the existing nodes I can see the management IP for the node is set on the virtual switch adapter
  • On the third node (HV3) I created NIC Team using both of the NIC's, I then created an external virtual switch using this teamed network adapter. However when I try to apply a management IP address to the virtual switch adapter it won't respond and I see a yellow triangle on the network adapter in the corner. When I remove the virtual switch and apply and IP address to the NIC Team the server is contactable and shows in the Cluster manager as up. However the problem then is I don't have a virtual switch.

If someone could help me with this that would be great - please tell me if you require further information.

Below is a screenshot of the adapter for HV1 (working fine) from failover cluster manager;

thank you advance :)

RDCMan VM console connect resolution?

I feel like I am missing some really small setting but I can't figure out how to configure connection screen size / resolution when using RDCMan 2.7 and VM Console Connect? If I use RDP connect it fills full window but if I use VM connect it is just 1024x768. If I use Hyper-V Manager to VM connect I can select size but that doesn't seem to affect RDCMan connection. Any hints on what I am missing?

Help needed setting up cluster communication network

$

Hi,

I need some help setting up a two node cluster communication network.

I have two virtual Servers each with four virtual nics.

I want to create a network for:

Management

Heartbeat

Live Migration

iSCSI

What type of switch would I need to create for each of them? (External/Internal/Private)

I presume that they would all have to be external as they will have to be able to communicate with the other host in the cluster through the physical network.

Would I need to configure VLANs on the physical switch to keep the traffic isolated? 

Thanks

Hyper-V Network NAT wired

Working with Hyper-V in Windows 8.1.  Configured the Network NAT using Ethernet (wired) is not working.  If I configured Ethernet NAT on my wireless card NAT works fine.

With both configuration, wired and wireless, do receive a 192.137.1.x IP address but the wired connection is not able to connect to anything.  

Server 2012 r2 Hyper-v guest network speed with 10 GB NIC's

$

Hi

Setting up a Server 2012 r2 Hyper-v host with an onboard 4 port 1 GB nic and a offboard dual port 10 GB nic. We are using the 1gb quad port for management. The 10 Gb we intend using for hyper-v guest use however we don't seem to be able to achieve very high speeds though the 10 GB adapter when assigned to a virtual switch. Testing the 10 Gb nic from the host confirms that we can transfer/get 10 GB speeds. When assigned to a virtual switch however the speed drops to about 1-2 Gbps. Has anybody seen anything like this ?. We've tried a variety of settings and i can confirm that the network traffic is using the 10 GB nic.

Hyperv networking nic teaming and vlans

$
0
0
I would like to bring up the topic of Hyper V networking and using nic teaming along with vlans via Windows Server 2012 R2.  I come from a Vmware shop one of our sister companies is going Hyper V so I decided to read up on it. From what I've read you have to configure vlan tags on each individual vm. So I would like to ask why can't I just create a nic team in windows than create sub teams off of that? After that go into the Hyper V switch manager and create a vswitch that's attached to the sub teams nic. That way an admin does not have to go into each vm to assign a tag to a  guest vm. I was reading that this is not recommended and you should tag each vm with the tag of your choice. I know that if you have a lot of vlans this would result in a lot of vswitches. However, if you are configuring management traffic or storage traffic than it's ok to use a sub team. So in short why is it not advised to use sub team interfaces with virtual switches?

Hyper-V 2012 R2 creating a new vhdx and copying from a source vhdx will physical file size reduce?

$
0

Hi,

I'm running Hyper-V 2012 R2 as part of Server 2012 Essentials.

As seems common from other threads I've read I have created an expanding VHDX with a maximum size too large (almost the same size as the physical disc it lives on). Although there is only around 350GB of data in the VHDX, the actual file size is approaching 900GB on the host.

I'm using the "Add New Virtual Disk" wizard to make a new VHDX to replace this massive file. I want the contents of the old VHDX to be copied to the new one so in the add disk wizard I selected the option to copy the contents of my new disk from the original.

So my question is: the source VHDX is 900GB, the data inside the is around 350GB. What size is my new VHDX likely to be? Is it likely to reduce to nearer the actual data size?

I'm asking because I'm currently running this operation to an external USB drive and it's painfully slow - going to take hours to complete. If the size isn't going to reduce I may as well cancel it and look for a better option.

Any comments appreciated.

Hyper-V Snapshot Issue on Exchange server

$
0
0

Hyper-v 2008 R2

I have a 2TB host in which I am running 2 VM's

Exchange was a 900gb Fixed disk VM

Terminal server 200gb Fixed.

I was working remotely on my iPhone on the Exchange server (I know, don't ask) when I think I accidentally hit the snapshot button inside of Hyperv Manager.

The user called and said the server stopped working and I quickly realized it unexpectedly rebooted and the Address Book service failed to start automatically. I was trying to navigate my way around on my phone and thats when I think I hit the snapshot button.

I didn't realize this until 2 days later when looking inside my VHDS folder that a new AVHD file was created that was 818gb and timestamped exactly when I was working on it remotely.

The original VHD file was dated 2 days earlier and 825gb

The snapshot is NOT showing up in Hyperv Manager at all so I'm not sure what the best next steps are.

I figured I would first take the VM offline and export it to a another location before doing anything to preserve the Exchange server. I am running a Barracuda so I'm not worried about losing any email as that will trap everything.

I noticed in the settings of Hyperv Manager for Exchange that it is using the AVHD file as the primary file.

Questions

1 - If I take it offline, shouldn't the 2 files merge without me doing anything else? I just wasn't sure since the Snapshot does not show up in SCVMM or Hyperv manager.

2 - I should be able to see this process in SCVMM?

3- How long will it take to merge 800gb? I've seen varying results depending on disk speed, etc.

With an exchange server, this obviously needs to be done delicately without data loss. I assume my statement about the original Exporting of the VM will cover my bases for that?

Thoughts on how to proceed?

Thanks!

Jim

I am attempting to build a lab using 1 physical server and multiple VMs. My goal is to simulate a domain with approx. 6 servers and 2 clients. Later I will advance to a Hybrid Cloud. I only have one 10 gig Nic. I would like to configure the physical server as both Domain Controller and VM host. What am I not thinking of? If necessary I can dual home the server with an additional Nic.

How to COPY/MOVE between 2 different W2K12 R2 FAILOVER CLUSTER

$
0
0

Hello,

I'll have to perform a migration from different Cluster (From Cluster A to Cluster B)

Both cluster are quite similar and Virtual Machine migration using  SCVMM is working. 

But  that migration is done through 2 different datacenters (WAN), and when migration is done we will have to virtual machines IP, etc... (but this is another battle)

The question is that we would like to perform a Virtual Machine "copy" instead of perform a Move, the reason is that we would like to have a quick way to perform a Rollback in case of problems.

Move with Move-SCVirtualMachine it's easy, but there is no 'Copy' function.

I may work using some export/import techniques and recreate the VM resource on the target Cluster, but it requires some time and specific scripting.

Does anybody have any idea suggestion about how to do it?

Thanks in advance.

ODX on Dell MD 3XXX Storage will corrupt the VHDX

$

I have found that the latest version of the Dell MD Storage has ODX on by default. When using the storage migration with this turned on the VHDX files transfer instantly between the LUN's but the VHDX is corrupt and causes the Virtual Server to blue screen and then to never boot again.  I have yet to find a way to recover any data. 

My current work around is to disable ODX on the array itself which means that the data is transferred by the hosts, but does not corrupt the VHDX files.

show storageArray odxsetting;

set storageArray odxEnabled=false;
