Hi all,

Should I install SCVMM 2012 on a physical server or on a VM ? Is SCVMM 2012 sp1 supported on a VM ? 

SCVMM must installed on the host system? 

Thank you

Problem configuring Windows 7 Client for Hyper-V Management server.

0
0

Hello,

I have successfully configured other Window 7 Workstations for Remote Management of Hyper-V following the steps in this article:  

http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/11/11/configuring-remote-management-of-hyper-v-server-in-a-workgroup.aspx

This explains how to setup Hyper-V Manager when your server is not part of a domain.  However, I am having problems with one of my pc's.  After successfully executing winrm quickconfig I have the following problem executing the following command:

      winrm set winrm/config/client @{TrustedHosts="rlpserver"}

it comes back with the error:  Error: Invalid URI - cannot locate last token for root node name

rlpserver is a Windows 2008 R2 CORE Server that is running Hyper-V.  The server side has been successfully configured for Remote Management as I am able to manage Hyper-V from other devices.  I am able to successfully ping rlpserver.

Any assistance to resolve this problem will be greatly appreciated.

Regards,

Matt Paisley

Ping cannot resolve local host but nslookup can on Server 2012 core.

ping cannot resolve google.com

nslookup can.

The only thing I can possibly think that would cause this is the automatic tcpipv6 DNS servers on the iSCSI interfaces.

Is there a powershell command to disable protocals on the ports used exclusively for iSCSI?  Or is there a remote management way to do this?

ISCSI LUN connected Hyper-V Server 2012 does not show in diskpart list disk

I have a Server 2012 Hyper-V install.  It has 2 NICs one for access and one for storage.  I have connected to an ISCSI LUN using iscsicpl.  I have also setup a Windows 8 machine for remote management and I can connect to the Hyper-V server using Hyper-V Manager, Computer Management and Server Manager snap-ins.

Problem: Even though I have connected to the ISCSI LUN it does not show in DISKPART> list disk or in the Windows 8 Computer Management.  Only shows the Hyper-V install disk.

Any suggestions what I missed to get it to show so I can format etc. for use?

Pinging from host to VM returns Destination host unreachable - ping from VM to host is successful

0
0

I can ping from a VM running CentOS 6.4 to the host successfully but cannot ping from the host to the VM without receiving Destination host unreachable. I can view the arp entry on the host which clearly shows the correct mac address to the VM but fails with destination host unreachable.

I should also mention that I can access TCP/IP Services on the CentOS such as Oracle even though I cannot ping from the ManagementOS to the client without receiving the destination host unreachable.

I'm also using a teamed interface that the VMSwitch was created from.

New-NetLbfoTeam -Name "ConvergedNetTeam" -TeamMembers "LAG01", "LAG02" -TeamingMode LACP -LoadBalancingAlgorithm HyperVPort -Confirm:$false

Name                   : ConvergedNetTeam
Members                : {LAG02, LAG01}
TeamNics               : ConvergedNetTeam
TeamingMode            : Lacp
LoadBalancingAlgorithm : HyperVPort
Status                 : Down

New-VMSwitch -Name "External" -NetAdapterName "ConvergedNetTeam" -AllowManagementOS 1

What is even stranger is that the host I'm pinging is replying with the destination host unreachable message.

C:\Windows\system32>ping 192.168.1.35

Pinging 192.168.1.35 with 32 bytes of data:
Reply from 192.168.1.35: Destination host unreachable.

Reply from 192.168.1.35: Destination host unreachable.
Reply from 192.168.1.35: Destination host unreachable.

This is the result if the host is not alive which makes sense since the 73,68,66,73 and my local interfaces.

Server 2012 Hyper-V Team

Hey all, I plan to setup my teams as follows:

6 x 1GB VM Ports (Teamed using three ports on quad port card 1 and three ports on quad port card 2)
2 x 1GB Management\Cluster Communication Ports (Teamed on the two on-board\embedded)
2 x 1GB Live Migration Ports (Teamed via one port on quad port card 1 and one port on quad port card 2)

What I am wondering if it is ok to run the physcial connections for the team between two switches that are NOT stacked? I had planned to use an LACP etherchannel for each team. But I am wondering since the switches are not stacked if I need to use switch independant mode.

Extremely weird Host OS issue, Pinging it returns "Host not Found", but NSLookup works

0
0

I"m having an issue related to DNS (hostnames) and my Hyper-V 2012 host, and I hope you all can help.  I have a local network and every machine can ping the other just fine using IP Address.

However, none of my 'client' machines can PING my Hyper-V host (running Hyper-V 2012 Core) by hostname. It almost always returns "host not found".  When I use NSLookup {Hyper-V hostname}, it correctly returns back the correct result. It's strictly Ping that is not working.

I'm going to detail my exact setup to help better troubleshoot this:

Wireless Router:
Netgear WNDR3700 router (v4)
DHCP Enabled, DNSMasq Enabled
Has Static entry for Machine 4 (below)

Machine 1: 
Win8 Pro Desktop
Connected to Domain
Attached to Router: Wired
Dynamic IP address
DNS: gets DNS from Machine 4

Machine 2:
Windows 8 Pro (Surface Pro)
Connected to Workgroup (not Domain as Machine 1 is)
Attached to Router: Wireless
Dynamic IP address
DNS: Dynamic (i.e., Router)

Machine 3:
Windows Server 2012 Hyper-V (Core)
Connected to Workgroup
Attached to Router: Wired
Dynamic IP address
DNS: Dynamic (i.e., Router)

I have Enabled 'Reachable by Ping' in the command-line GUI

Machine 4:
**Virtual Machine**: Windows Server Essentials 2012
This machine is a Domain Controller (Machine 1 is a member of this Domain)
This is a Guest VM of Machine 3 (i.e., Machine 3 is hosting this VM)
Static IP address
Attached to Router: Wired (via Host OS).. this VM has an "external" network adapter that I specified so it can communicate with other physical machines on the local network
DNS: Set to itself (127.0.0.1)

The #1 issue I am having is that Machine 3 (the Hyper-V HOST) can PING ALL the other machines successfully, but NONE of the other machines (Machine 1, 2, or 4) can PING Machine 3 (the Hyper-V HOST).

Sometimes, very rarely, all of a sudden, Machine 3 is successfully pingable by the other 3 machines (For example, Ping keeps giving host not found, but all of a sudden it starts working), but usually after 15-20 minutes, it stops working again.

Since Machine 1 is connected via Domain to Machine 4, and since Machine 4 is a Domain Controller, Machine 1's DNS is pointing to Machine 4. Machine 1 has no problems pinging all other machines besides Machine 3.

Regarding Machine 2 (Surface Pro), for the most part it works good, however, sometimes it has trouble pinging Machine 1. Though it's a minor quirk and I blame that mostly on the Wifi adapter in the Surface Pro to being junky.

What's really crazy is that the Guest OS (Machine 4) of the Hyper-V host can NOT Ping it's Host OS by hostname.

I am completely baffled.  This is definitely a DNS issue but since it is isolated to the Hyper-V 2012 host, I thought it may be something with Hyper-V.

I would greatly appreciate any help you all can provide.  I was up until 4am last night trying resolve this, and I am all out of ideas.

Thanks in advance.



Network connections missing after vhd move

0
0
Ok I am not sure if I have done a virtual move properly but what I had done was move 3 host servers(I just copied the VHD files over to the new server).  1 was an Ubuntu server, another a Windows 2003 and the last was Windows 2008 R2.  I moved them to a new Hyper V server running 2008 R2.  Now I have no problems with 2003 and Linux but the 2008 host is giving me network connection issues.  What I mean is I don't see network connections at all.  I had removed the virtual network connections from the settings and added them and when I boot up I see them!  Great!  Well, about 10 seconds later they are gone.  I have just enough time to go in and add the ip address to it.  One thing that is different is the 2008 R2 had a snap shot and I told Hyper V to use the AVHD file as the host hard drive.  Any ideas what is happening to my network connections?

replica 2012 server

Hyper-V Replica
We have A customer he does not have budget to buy the SAN Storage with San Switch & I nn the same time he need to consolidate 4 physical servers,(NAV 2011.LaserFish archiving  , CRM2011, Files Sharing Server) into 1 high specification HP Server with dual processor  and 48 Gb ram and 3x300GB sas 10 K  and 3x600gb SAS 10k for database , and he ask for high availability , so since he doesn’t want to pay for the storage
I have a question if it is recommended to have 2 servers with windows 2012 hosting 4 VM, and then create a replica between 2 servers in order to have availability when 1st server failure we can manually make the 2nd server up,
My question if this solution is the recommended? Or not ideal solution then we must have to convenience the customer to go for SAN storage solution then he has to consider to increase the budget

Hyper-v Network Setup

I've been having a hell of a time setting up a network for a vm - My server has a quad port network port where two nic ports are bonded and another ive setup to handle hyper-v network flow. At first I tried to create an external adapter from the bonded adapter but I could only get local network. I'm trying through the dedicated adapter I setup but I cant even get a local network. My goal in all this is to let the vm's talk to the outside world and connect to the internet.

Here is what I'm working with:

Host Adapters:

adapter that was created from vm

How The above network is setup:

Lastly the VM

This probably seems all confusing and I'd be willing to start all over but I could use some help. Its being hosted at a datacenter and we were given the subnet 192.168.111.xx for our servers. Thank You for any help.

Best configuration for Hyper-v Server

0
0

Hi, this upcoming weekend I will be setting up a Hyper-V host with two VMs, and would appreciate some advice regarding how to configure them for the best performance.

The physical server itself will be a Dell PowerEdge R720  with 48 GB of RAM, dual Intel Xeon E5-2640 2.50GHz processors, and six 600GB 15K RPM drives running in RAID 10 for 1.8 TB of hard drive space, plus a hot spare. The volume license of Server 2012 that we have purchased includes the rights to install two VM instances of it, plus downgrade rights to Server 2008 R2 and Server 2008 R2 Enterprise.

The host operating system will be Server 2012 with the Hyper-V role alone enabled. It will be dedicated for this purpose.

One VM will be the domain controller for a local network with 15 PCs. The XP, Vista, and Win 7 PCs on this network. I have not yet decided to make this VM 2012, 2008, or 2008 enterprise.

The second VM will be a 2008 R2 Remote desktop server with 10 remote desktop licenses. It will also host Medisoft running on an Advantage database.

Later this year a third VM will be added, perhaps along with some additional memory - a 2008 Enterprise SQL server to run AllMeds.

Here are my questions.

  1. How would you recommend we partition the Raid 10 array?
  2. Given an environment of XP, Vista and Win 7 workstations, what OS would you recommend we make the domain controller VM, and how much memory and drive space should we assign to it? It will be a dedicated domain controller.
  3. How much memory and drive space do you believe we should assign to the Remote Desktop Server and Medisoft VM? Please keep in mind that we will need to reserve the bulk of our drive space for the AllMeds VM to be added later.
  4. There will be 4 Gigabit network ports. How would it be best to configure them? Do you recommend teaming, or assigning a port to each VM? We do not have a managed switch.

Thanks very much for sharing your thoughts!


Try to live at peace with all men, but never at the expense of peace with God - or your conscience.

Server 2012 using Hper V to Create new VM and Running Remote Desktop on the VM

0

I have a new Server 2012 server that I would like to create 2 VMs on it using Hyper V then use both of them for Remote desktop servers, but why I try to do it i get an error message that says a Virtual Server cannot be a remote desktop server?

i would prefer to use 2 VMs vs one physical server since the VMs boot much faster.

Add Quorum Disk to exsisting Cluster

Hi,

We had some issues with our SAN, these have now been sort of resolved, We have 1 issue left... our Quorum disk... the partition itself ended up corrupted & no usem, so we were advised to re-initialise the disk. Which was done. Now we need to add the quorum disk back into our cluster. Is it as straight forward as it looks?

add storage on cluster management

then reconfigure quorum to do disk+node for failover?

 Thank you

Hyper V-Clients very slow on windows server 2012

0

Hi,

I already found this topic several times in this Forum. But none solution worked for us. I searched like the wohle internet to find a solution but didn't find any. Maybe anyone in here can fix our problem.

First of all, server we are talking about is this one: HP proliant DL360p g8 running windows server 2012 on it (64 gig ram, 2x16 cores)

When we connect with any client using RDP on a VM(vm is a 2012 server) it is really slow. If you type anything it will take several seconds until you see the letters.

VMs are on a different HDD, we tried to enable/disable teaming, shared memory, no antivir is installed - we are running out of possibilities/ideas and would appreciate any help.

regards,

Sebastian


Windows Server 2012 - Can occasionally not access second virtual hard drive inside a VM

0
0

I run Windows Server 2012 RTM Hyper-V and I can occasionally not access the second virtual hard drive (dynamically expanding VHDX) attached to the VM through the virtual SCSI controller. I can however access the first hard drive that is connected with the virtual IDE controller.

I get the following warning in the event log under “Administrative Events” every 30 seconds when this happens:

  • Log Name: System
  • Source: Storvsc
  • ID: Storvsc
  • Message: “Reset to device, \Device\RaidPort0, was issued.”

I get this error once or twice a week and it has caused serious problems since one of the virtual servers that have this problem is a fileserver and the second hard drive contains all the data.

The only quick solution to the problem that I have found is to force the virtual machine to stop using the “Turn Off” feature since a normal shut down does not work (stops at shutting down the event log or similar) and then start the virtual machine again.

You can also wait for about 30 minutes or longer until the disk for some reason becomes accessible again by itself.

My research into this problem shows that:

  • Only 2 of the 10 VMs running Windows Server 2012 RTM that I have, have this problem.
  • Both these VMs have a second virtual hard drive (dynamically expanding VHDX) that cannot be accessed for 30 minutes or longer.
  • Check Disk of the virtual hard drive shows no errors.
  • The second hard drive is attached to the virtual SCSI controller.
  • I can find no problems at all with the physical storage on the (not related) 4 hosts that I have. The problem exists only in the VMs.

I have now attached the second virtual hard drive to the virtual IDE controller to see if this permanently fixes this problem (i.e. does not happen for at least a week).

Is there something wrong with the virtual SCSI controller or the virtual SCSI device driver that comes with Windows Server 2012 RTM? Does anyone else have this problem?

Access Device Manager in Hyper-V 2012

When I try accessing Hyper-V Server 2012's Device Manager via MMC I get "Make Sure that this computer is on the network, has remote administration enabled, and is running the "Plug and Play" and "Remote registry" services.

The Error Was: "The machine selected for remote communication is not available at this time.

I disabled the Hyper-V Firewall and followed the steps outlined here for "Allow remote access to the Plug and Play interface":
http://mikefrobbins.com/2010/12/02/enabling-remote-access-to-device-manager-on-server-core/

Any ideas?

The Hyper-V Manager works as-well-as the Policy Editor, just not Device Manager.

iSCSI failure of Hyper-V Passthrough Disk leads to Disk going into RAW State

0

Hi,
I have the following Setup.
2 Node Cluster with a CSV for the VMs on a HP P2000 and a second Volume also on the P2000 added to the CSVs of the cluster.
The second Volume is our Mail archive and is connected to VM as a physical disk.
For some reason the iSCSI network connection failed today, I was able to get it running again, however our Mailstore Volume is mounted as NTFS on the Hyper-V Node and as RAW on the VM.
I can't assign the Volume a Driveletter on the Node though either.
Is there any other way I can access the files or, better yet get it to mount as NTFS again on the VM ?

Thanks and regards

Hi,

I've win 2012 std with hyperv role on it.

i've setup a virtual machine with 1 IDE disk and 1 SCSI disk all VHD on local disk.

when i monitor the server with veeam one it report that the Virtual Storage Error Count in large (9) on the SCSI driver even if this drive is not loaded at all.

why is that?

dyanmic memory configuration during run time

0

 hyper-v host or Win8 host will not permit me to configure dynamic memory during run-time.  This is apparently not true for me:

From: http://technet.microsoft.com/en-us/library/hh831766.aspx

Run-time Dynamic Memory configuration changes

Hyper-V in Windows Server 2012 enables users to make the following configuration changes to Dynamic Memory when the virtual machine is running:

  • Increase the maximum memory.
  • Decrease the minimum memory.

What am I missing?
