Hi all! I'm working with Hyper-V Server 2012 R2 (fully patched).
new-vhd -Path c:\util.vhdx -Fixed -SourceDisk 3 -SizeBytes 50GB fails with the errorNew-VHD : Parameter set cannot be resolved using the specified named parameters.
However, if I run the command above without either the SourceDisk or SizeBytes parameter it succeeds. It only fails when they're both present. TechNet documentation shows both parameters in the same command. Does anyone know what I'm doing wrong?
Hi,
I, have two DELL R420 (single processor 12 vCore) as identical Hypervisors (Window 2012R2 or Native Hyper-V), each running 3 clustered VM.
How many Windows 2012R2 Standard License I need to buy?
I think i can bought 3 x Dell Windows Server 2012 R2, Standard - ROK EN - what do you think?Hello,
I have recently purchased a dedicated server online, and a fresh copy of hyper-v has been installed. This is the free version, and not what's included with Windows Server 2012 R2. I have a quick question. I can RDP into my server, which is located on the Internet. When I try to connect an MMC snapin, like Hyper-V manager, it is inaccessible. Is there a way to manage hyper-v servers found on the Internet? And, if so, is this a good idea?
Thanks to all that reply,
Mike
Hi everyone,
The question is simple. My NIC is a Realtek PCI GBe familly controller, Priority and VLAN are enabled. I havent any physical switch and when i create an external virtual switch on hyper-v if I add a VM on VLAN 2 why it doesnt have Internet access or can pingn the router ?
The virtual external switch has no default vlan on it, so it supoosed to be on TRUNK mode. I also have a static route on my router 192.168.2.0/24 -> 192.168.1.254.
If I add a VM with no VLAN tag and manually assign the IP adress it can communicate with the router but if I add a VLAN tag it doesnt.
What you think ?
Thanks
Hello,
I have a question about Hyper - V replica.
I have configured Hyper - V replica for one virtual machine with Windows Server 2008 R2 (hypervisors are using Windows server 2012R2). I have created also backup with windows backup in recovery site. I have the following issue:
Second server has stopped to be replicated before a month and there is no working backup either.
I have a problem with the primary Virtual machine and it is not working now. I checked the log in primary hipervisor and it looks that there some data that should be replicated.
I was wondering whether if i start the secondary virtual machine the replication will be resumed to the last available snapshot?
Thank you in advance!
I am experiencing an interesting problem with our Windows Server 2012 R2 three node cluster. On one of the nodes network connectivity tends to drop randomly for the virtual machines network interface. The associated network card on the affected node indicates a connected as well as all the virtual machines on the affected node. This only happens for the network attached to the production virtual network. Live migration and the CSV virtual networks never lose connectivity.
Rebooting the virtual machines does not resolve the problem. Only physically unplugging the affected network cable and plugging it back in resuming network connectivity.
All host are up to date via Cluster Aware Updating and the network card drivers are all current.
The frequency is totally random sometimes in between two days to two months between incidents.
Any thoughts on a cause?
Had a SAS controller failure on a Dell R710, that house Exchange 2010, so was trying to stand up Exchange 2013 in coexistence mode, as I got Exchange 201 VM back up. On another R710, I had the DC 2009 R2 on a VM, so on a 3rd R710, I started a 2012R2 AD and joined to domain so I could use the second R710 as a host for 1st that failed to export VMs and save them.
The DNS for whole network went down and I discovered the DC on the second R710 had stopped, Tried to start it, but got failure to initialize 0x80070005. I noticed that the avhd file no longer exists.
We have 2 R820 Dell servers with 4 10Gbe nics-
We plan or have currently setup the following :
Windows 2012 R2 DC
Questions we have:
What is the role of the "Management Network"? Is this role to be the management of the Host and Hyper-V via SCVMM?
Which Network should have the default gateway configured and DNS in AD ? Management or Production?
We have a current setup that was done with out a management network initially and just a production network, the VSwitch was set to AllowManagmentOS: True (This I read a lot should be false - right? and if so what are the implications of changing it now or can it be without interrupting the current setup?)
Thanks for any help and if you need more information no problem -

Hi,
What is the best practice for formatting CSV LUN for hosting Exchange/SQL Server VM?
Can the CSV be formatting with 64K allocation size unit and VM OS VHD with 4K, SQL/Exchange Data VHD with 64K?

Hi all,
I have some strange network issue with my Hyper-V computer.
The server is PowerEdge R820, with 2 Broadcom BCM57800 NetXtreme II 10 GigE (NDIS VBD Client) adapters and 2 Broadcom BCM57800 NetXtreme II 1 GigE (NDIS VBD Client) adapters. OS is Windows Server 2012 R2 with the latest updates installed.
I configured one External Virtual Network bind to a 1 GB adapter(let's call it vSwitch-1GB) and one External Virtual Network bind to a 10 GB adapter(let's call it vSwitch-10GB). When the VM connect to vSwitch-1GB, everything goes fine, it can get IP address and can ping other machines in the same LAN, and vice versa. However, it the VM connect to the vSwitch-10GB, it can get IP info, but most of the ping failed, and vice versa.
I tried to use the build-in driver, tried to disable TCP Offloading and other Offloading, tried to disable power saver on the network adapter, but the same issue persist.
Hi all,
I have been struggling to get Shared VHDx to work properly for the last week or so. I have a two 2012 R2 file server VMs clustered sitting on a Windows Server 2012 R2 Hyper-V cluster, I would like to use Shared VHDx for the Quorum Disk Witness and for the File server cluster storage.
Initially when I first create, share and add the VHDx to the two file servers it works without an issue, the file server cluster role will live migrate and storage stays accessible. However after a period of time e.g. overnight if either of the servers are shutdown/restarted they will not restart. The error I receive is:
'FS1B' failed to add device 'Virtual Hard Disk'. Failed to open attachment 'Path to disk\Quorum.vhdx'. Error: 'The request is not supported'. 'FS1B': Cannot get information for attachment 'Path to disk\Quorum.vhdx'. Failed to open attachment 'Path to disk\Quorum.vhdx'. Error: 'The request is not supported.'.
I have searched around online and came across a couple of people with a similar issue, one fixed it with adjusting his Network Binding (this did not help me). If I turn off the sharing on the VHDx the server it is attached to will boot fine.
I have also made sure the networking and storage access to the Hyper-V hosts are identical and that all four servers are up to date patching wise.
I don't think I'm missing anything but it really doesn't want to work and driving me a little nuts.
Thanks!
Hi,
Currently my server running Windows Server 2012 R2 Standard. I want to set one Hyper-V Guest inside it running Windows Server 2008 R2 Standard. As far i know, guest network will share with host connection. Is it mean if host network no connection, guest network also got no connection?
Thanks.
I have three new rack server ,each with two processor , each processor has 8 cores.
the question:- how many WinSvrDataCtr 2014R2 needed?
We have a server 2012 standard hosting 2 Hyper-V machines, one is our Exchange and the other our App server.
We had a power outage last night and it looks that the host shut down cleanly but the VM's did not.I checked the event logs and the VM's are showing an unexpected shut down exactly the same time as the Host server. The host server event logs is showing "Event
6006" which to me is a clean shutdown.
Hyper-V Guest Shutdown Service is running on both VM's. On the Host that service was set to "Manual (Trigger Start)". I'm not sure what that means but I changed it to "Automatic (Trigger Start)"
Also, I tried to start HV Guest Shutdown Service on the host server but it just starts and stops. Is that because the startup type is set to "Trigger start"?
Any help is greatly appreciated. Thanks
Hi all,
I have been running Windows 8.1 and in Hyper-V Manager, i can see 2 VM ( 1 Linux-Ubuntu , 1 Win 7 ) for couple of months.

I dont know what is going on... When i open Hyper-V Manager i can start/stop VMs and i can see from preview that they are running.
Hi,
I, have two DELL R420 (single processor 12 vCore) as identical Hypervisors (Window 2012R2 or Native Hyper-V), each running 3 clustered VM.
How many Windows 2012R2 Standard License I need to buy?
I think i can bought 3 x Dell Windows Server 2012 R2, Standard - ROK EN - what do you think?Hi,
my Scenario:
Primary site - Hyper-V Cluster Windows Server 2012 R2
Replica site - Hyper-V Host Windows Server 2012 R2, same IP subnet
several VMs with SQL 2012 SP1 and SQL 2005/2008, SQL on same VHDs and on different VHDs (Set-VMReplication -VMName <vm-name> -EnableWriteOrderPreservationAcrossDisks 1)
VM Integration Services: 6.3.9600.16384
doing Application Consistent Recovery Points on the SQL-VMs which seems to running well...BUT if you look at the Application-Log inside the SQL-VMs I get following errror every time a Application Consistent Recovery Point is running:
SQLVDI: Loc=SignalAbort. Desc=Client initiates abort. ErrorCode=(0). Process=2644. Thread=7212. Client. Instance=. VD=Global\{3346955E-6377-4992-BA65-5DB64EFA8399}1_SQLVDIMemoryName_0
BACKUP failed to complete the command BACKUP DATABASE model. Check the backup application log for detailed messages.
BackupVirtualDeviceFile::SendFileInfoBegin: failure on backup device '{3346955E-6377-4992-BA65-5DB64EFA8399}1'. Operating system error 995(error not found).
Same error on all my SQL-VMs.
VSS Backup (within the host) of my SQL-VMs with Windows Server Backup works as expected without any Errors.
So I believe this is an Hyper-V Replica issue not an SQL issue!
I did the same tests on a completely different Hyper-V Replica Environment without Hyper-V Cluster --> same errors
any ideas....
Thanks for any replies...christian
Hello all
Windows 2012. Hyper-V Manager.
Question: Is there a way to have a prompt (OK/Cancel) when using the option to delete?
Once I meant to rename a computer (right click on VM) but since it's the option above delete, I accidentally deleted the virtual machine instead. I would like to know if there is an option to have a pop-up prompt to select OK or Cancel when deleting a virtual machine.
Dear all
I recently discovered that all my Windows VM's (2003/2008/2008R2) start and stop the virtual disk service:
System Log File:
08:37:27 Virtual Disk Service --> Service started
08:37:27 Service Control Manager --> The Virtual Disk service entered the running state.
08:37:28 Virtual Disk Service --> Service stopped
08:37:28 Service Control Manager --> The Virtual Disk service entered the stopped state.
and i have this entry every minute.
I removed the DVD Drive from the VM but no change. What could be the reason for this? All my physical servers with the same backup program haven't this behavior.
Thanks for any hint
JBAB
