Move VDC 2012 R2 to different Hyper V Host

0
0

Hi,

I prepared one virtualized DC 2012 R2 on HV host 1.

I now want to move (not clone) that VM to HV host 2.

I understand that Export etc. is not recommended by MS due to USN rollback etc.

Can anyone advise about the recommended method of moving a VDC? (Live Migration is not possible)

Thanks

Hyper-V Setup, Novice question.

0
0

Setting up my new server here is my setup

A - Raid1 (2) 1TB drives / Sata

B - Raid 10 with hot spare 5 (600GB) drives / SAS

C -Raid 1 (3) 2TB drives one pulled out / Sata

This is what I want to achieve Hypervisor on A on a 200 GB partition, the remaining 800 used for junk storage for one of the VM

Virtual machines on B possible 2 -3 machines,  one of the Virtual machines will use (A) the remaining 800GB as junk storage.

Another Virtual machine will use C as the Backup to Disk, then I hot swap this with the 3rd drive I have one a week. 

When I installed the 2012 server hypervisor on A it was installed on a 200GB partition, 

When I installed my first Vm copied the iso to the 200Gb partition on A, from there I went to install the VM and the only drive option i see is the 200Gb on A.

When I attempt to add more drives through the New / hard disk I see my partitions, but I see the option of copying my virtual machine to the partition, I though I could initialize them right now it's creating a new virtual hard disk which is taking some time, based on my desired setup above is this possible for what i want to achieve?

vhdx file - free space at the end. How to decrease the physical size

0
0

Hi,

A vhdx file was splited to tree logical disk in the past:
c: <-- approximately 80GB
d: <-- approximately 250GB
e: <-- approximately 250GB
and the total physical size is 537GB

Than the logical disk e: was deleted ("delete logical drive" in disk management).

How to decrease the physical size of the vhdx file ?

Is it possible ?

We have a requirement to query all diskcontrollers in Hyper V using WMI(C#).Also it is necessary to query the Disk information along with its partitions data . We also requires the disk volume informations along with its partitions.

Nic Teaming Server 2012 R2 How do I use nic teaming and assign my NIC resources to the VM's

0
0

I just created a 2012 R2 Datacenter server on a Dell T110 II,  I have the 1 internal nic and a 4 port network card. So I created  team1 of the 4 ports from the card. When I create new VM's do I point them to the Nic Teaming (Team1) adapter and then all new VM's will take advantage of the 4 ports of teaming? or do I point them to the existing internal nic on the server and purchase another 4 port card?  All of this is in a lab so top performance is not critical but I would like to use best practices and make sure I use the equipment the best I can.

Thanks Jim

I have Server 2003 x86 installed on Server 2008 x64 Hyper-V. I have been trying to upgrade Server 2003 to 2008 standard, but it freezes at first boot after installation with just a mouse icon in the center of the guest window.

The steps I have taken:

Make a copy of original VM in case of disaster.

start up copy

uninstall powershell 1.0 and hyper-v guest add-ons/drivers

insert tested Server 2008 standard x86 iso and start upgrade installation

install success and reboots.

Windows load screen, goes black, mouse icon appears, hourglass icon appears momentarily.

screen stays black with mouse icon with no change even next day.

Hyper-V NDIS Capture Extension Error

0
0

I have server 2012 R2 Datacenter running with several HyperV hosts on it.  The Intel Nic Drivers are 2012R2 out of the box drivers. I am setting up a monitoring VM to capture packets following these instructions. (I am also replicating the traffic on my Switch to the port the NIC for the Virtual Switch is connected to that I configured as the Mirror from the instructions.)

http://blogs.technet.com/b/networking/archive/2015/01/06/setting-up-port-mirroring-to-capture-mirrored-traffic-on-a-hyper-v-virtual-machine.aspx

When I enable the Microsoft NDIS Capture Extension on the Virtual Switch I want capture the traffic on, I get the message: 

"The Selected Extension is not operating correctly.  Check the event logs for further information. If this is a non-Microsoft Extention, contact the vendor for further troubleshooting steps." 

I looked in the event logs and cannot find any errors in Application or System.  I even turned on the show analytic and debug logs option and dug into the:

Applications and Services Logs ---> Microsoft --> Windows --> NDIS/NDIS-PacketCapture logs and didn't see any errors.

I cannot figure out why I am getting this error.   Does anyone know where else to look or why this error is coming up and how to fix it?  Again these are out of the box drivers and the Microsoft NDIS Capture Extension.

Thanks

Cannot Start the Virtual Machine Because the Hypervisor is Not Running

0
0

Hello,

My home server is a Dell Dimension E521 running Windows Server 2008 x64 using the following hardware:



I am trying to run a VM using Hyper V but get the following error when starting the machine:

The Dell BIOS in this particular machine enables hardware virtualization by default despite not offering an option in the setup utility. SecurAble shows that the machine is capable of running virtualization:

 

The SecurAble test was run with Hyper-V installed and enabled which does seem strange as I was told that Hardware Virtualization showed as NO when in this state. I don't know of this has something to do with the machines being configured via RDP but I can't see why it would.

All help is greatly appreciated.

Thanks
Jake.

Basic Hyper-V Replication questions

0
0

Hello,

     I'm new to setting up Hyper-V replication and would like to first start by describing my environment.

Location A (Primary Site)

Two node Server 2012 Hyper-V host cluster. Fiber Attached storage. I have a CSV assigned to the cluster dedicated for replication. Network address = 172.24.110.xxx. All servers are assigned static IP addresses.

Location B (Secondary Site)

Two node Server 2012 Hyper-V host cluster. Fiber Attached storage. I have a CSV assigned to the cluster dedicated for replication. Network address = 172.24.60.xxx. All servers are assigned static IP addresses.

I have the Hyper-V Replica Broker setup on each cluster in both locations, both sites can replicate to each other and I pointed the default location to store the replica files to the C:\Clusterstorage\Hypervreplication volume that I created strictly for replicated VM's.  I've successfully tested replication from Location A to Location B. When I look at the volume that contains the newly replicate files, I have a folder called "Hyper-V Replica". Within this folder I have four other folders. They are as follows: Planned Virtual Machines, Snapshots, Virtual Hard Disks and Virtual Machines. One of my issues is that everything seems to be based off of the VM's GUID. It seems difficult to keep track of the name of each VM that would get replicated to this volume. Is there a way to easily identify which VM's files are in a particular folder? I ask because when you create a new VM on a volume, the folder is named whatever the VM is named which makes it easy when you have 300 or so VM's to deal with.

My other question has to do with the IP addresses. Location A and Location B are both on the same domain but each location uses a different network address. I join the VM to the domain at Location A (Primary Site) using a 110 network address and then plan on replicating it to Location B (Secondary Site) that uses a 60 Network address. Once I enable replication on a VM, I then can add the failover TCP/IP address for the .60 network. Once the VM has completely replicated, I'll turn the VM off and do a planned failover. I turn on the replicated VM at Location B but I'm unable to ping the VM by name or remote desktop to the VM. I'm sure this is because DNS does not have the IP address resolving to the name. Do I manually have to enter in the DNS records for the 60 network? Is there an easier more efficient way of bring the replicated VM online when using static addressing? If anyone see's anything I'm doing wrong please let me know or let me know if there is a better way of doing what I'm trying to accomplish. Hopefully I explained things clear enough. lol Thanks

How to go back to Win 8.1 after installing Hyper-V server 2012 r2

0

Hi. I installed Hyper-v server 2012 R2 on a Toshiba running windows 8.1 64bit and now I can not go back to windows 8.1. Every time i start the computer it asks for my password and opens system32/cmd.exe and sconfig.cmd consoles

MSVM_ComputerSystem WMI class returns only Hyper-V host

0
0

Hi All,

Having  a problem in listing list of virtual machine from Hyper-V host (Windows 2012 R2) using WMI query remotely. (select * from MSVM_Computersytem).  The query lists only Host system and no virtual machines are listed. 

WMI query is ran in the context of domain user from a remote system and has all required permission to Hyper-V host’s WMI name space (\root\Virtualization\V2).  There is no error in connecting to Virtulization\V2 name space.  I don’t see any WMI events in event logger as well.

With similar permission we are able to query WMI classes in root\cimv2 name space but unable to get data from WMI classes in root\virtualization\v2 name space

Virtual machines are listed when domain user provided with local admin rights of Hyper-V host.

The systems are in highly secured environment and we don't want to give local admin rights on Hyper-V hosts.

Domain user is also part of “Performance Monitor Users”,  “Distributed COM Users” and “WinRMRemoteWMIUsers” Windows groups  and has permissions as shown in below screenshot.

What additional permission is required to get list of VM’s remotely without giving local admin rights.


Regards


Virtual (Hyper-V) MS Server 2012 R2 crashes with BSOD bugcheck code 0x19

I have several virtual (hyper-v) Windows 2012 R2 servers that crashes at the same time at night with the same error.

Bagcheck code is 0x00000019 (0x0000000000000020, 0xffffe0001bf77000, 0xffffe0001bf772c0, 0x000000000c2c0000)

At this time Sophos AV begins scheduled scan job. Analysis of dump file shows that 

Probably caused by : spaceport.sys ( spaceport!SpSpaceDeviceControl+193 )

Excluding spaceport.sys file from scan does not resolve issue.

I also noticed that BSOD appears when Sophos AV tries to scan MBR.

We use Sophos AV inside the VMs.We have 4 of 9 problem systems that were deployed form one template.

When I disable MBR scan in AV - scan completes successfully. But I think that it's not a secure way to resolve the issue.

Could anyone help me to resolve this issue?

Replication to a server with removable external drives for VHDx files

0
0

Hello,

I currently have 2 host servers and replication is working fine between them.   The customer would like a cheap offsite storage solution that would allow them to easily transport a hard drive backup offsite once per week.

I was wondering if we could extend replication to a PC with a toaster/drop in external drive.  The VHDx files would get copied there.   My concern is that when they swap out the drives - what will happen - is there a way around issues from that?


Monitoring virtual switch Hyper-V

0
0

Hello,

I have a Hyper-V (WS2012 R2) with 150 VMs. I use a monitoring application which is called "Cacti" (like Nagios).

That's why I want to monitor the Hyper-V's virtual switch on this app (bandwidth for each Vm). Is it possible with SNMP installed on the virtual switch ?

Thank you.




Linux vmdk file instant growth

Hello!

We've got Hyper-V 2012r2 and CentOS 6.6 running in VM.

We have web-server running on it. And in fact it uses space:

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_bitrix2-lv_root
                       50G  3,7G   43G   8% /
tmpfs                 1,9G     0  1,9G   0% /dev/shm
/dev/sda1             477M   46M  406M  11% /boot
/dev/mapper/vg_bitrix2-lv_home
                      439G  101G  316G  25% /home

But vmdk file in Hyper-V weights 300Gb.

I tried 

cd / ; cat /dev/zero > zero.fill ; sync ; sleep 1 ; sync ; rm -f zero.fill

And after that:

Mount-VHD 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx' -ReadOnly
Optimize-Vhd -path 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx' -Mode Full
Dismount-VHD 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx'

But it doesn't help..Can anyone help us with the problem?

Application using Multicast IP settings

0
0

Hi,

We are using SCVMM 2012 R2. I have a windows 2012 R2 virtual machine which has two NIC (Live and Management), and is running an application which advertises to a multicast group ip address of 224.10.10.10 with a port of 31337, and the windows 7 clients are supposed to join this multicast group using the client application to listen for the server advertising packets.

However, the clients never receive any information from the server. I checked on the router and the server doesn't join the group. I've run a test program on the windows 7 clients with the ip address and port number above which sends an hello message to other clients running the client software which worked since it crashed the program on all those machines (they didn't know what to do with the hello message I sent them), so I know they are all listening and received the test data.

If I run another test program which has a server part which sends out a message (ip address above and port number), and a client test program (ip address above and port number), on the server to receive the message, this also works, since the client displays an hello message.

The part that doesn't work is the server sending out information and the clients receiving it (also tested with the server and client test app)

netstat on the server:

UDP    0.0.0.0:31337          *:*                                    3960

and on the client:

UDP    0.0.0.0:31337          *:*                                    5680

Previously we were using physical machines running windows 2003 with the same application and this worked fine. If I reboot this server, then check the router I see multicast information appearing.

If I run the following on the server: netsh interface ip show joins, it give the following information:

Interface 12: Live

Scope       References  Last  Address
----------  ----------  ----  ---------------------------------
0                    0  No    224.0.0.1
0                    1  Yes   224.0.0.252

Interface 13: Management

Scope       References  Last  Address
----------  ----------  ----  ---------------------------------
0                    0  Yes   224.0.0.1
0                    1  Yes   224.0.0.252
0                    1  Yes   224.10.10.10

The 224.10.10.10 appears on the management NIC which seems incorrect since it should appear on the Live NIC which has a default gateway configured (Management does not)

Are there any special settings I need to set on the Hyperv client? How do I get the multicast group to bind to the Live NIC.

I have set the live nic to be first in the list to be accessed by network services and IPv4 binds before IPv6.

Thanks.

Import and Export Hyper V 2012

0
0

Hi Peeps,

I am trying to get around the fact that Hyper- V does not have the cloning feature that Vmware has by performing the Import and export feature in Hyper-V but I am getting an error for something that seems so basic.

The Error " A server error occurred while attempting to import the virtual machine"

Import Failed. Unable to find the virtual machine import files under location "F:\Path". You can import a virtual machine only if you used Hyper-V to create and export it"

The steps I took are the following

1. Turned off the target VM ( I couldn't export it anyway without turning it off)

2. Right click on export and then Selected the target location to keep the file.

3. After "export" I checked and confirmed that a new VHD file had created.

4. I click on Import VM and point to the folder where the newly exported VHD file is and I get the error message.

<g class="gr_ gr_87 gr-alert gr_spell ContextualSpelling ins-del multiReplace" data-gr-id="87" id="87">Infact</g>  It seems that none of the other VM's I created using the Same Hyper-V 2012R2 can be imported.

Any Ideas

Hi,

Just built a Server 2012 R2 Hyper-V failover cluster connected to Equallogic 4110 storage arrays with latest firmware and HIT kits. 
When creating a clone or vm from a template we see that the cluster loses access to the storage csv volume that is hosted on the equallogic storage with the following errors:

Cluster Shared Volume 'Volume1' ('CSV Disk1') has entered a paused state because of '(c0000435)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Can anyone shed any light onto this issue?
