DHCP and Private Virtual network = APIPA (Hyper-V 2012)

0
0

I have a Desktop on which 2012 has been installed.

This desktop has no network and i prefere to remain it that way since it is only used for testing purposes.

So i've created some VM into a Private network but none of the VM does receive any valid ipadress.

Who provides ipadresses when the Private network is choosen ? and how can it be setup ?

Thanks for your help.


Server Core 2012 - Server Manager Works, but Hyper-V Manager does NOT Connect

0
0

I have been working on this for several days...read every article out there (I think)
SetUp:  Windows 8 machine connecting to a Server Core 2012 install (WORKGROUP - not Domain)
I am able to connect to the Server2012 install via Server Manager, but Hyper-V Manager will not connect.

I have the Hyper-V Tools on and I have tried turning both client and server firewalls off.

Any help/insight would be greatly appreciated.

Can I simulate a WAN link with Hyper V?

0
0

I want to test RODC installation and configuration before deploying the RODC to branch offices and for this lab I only have one server which is the Hyper V host running 2008 R2. I have two virtual servers (server 2008 r2), one is the writable DC and the second the RODC. In Hyper V, can I create a virtual router that can be used to simulate a WAN link or disparate networks?

Thank you for your time.

Luns are unavailable

I am having a EMC VNX storge and having HP C7000 enclosure of 16 bays, I have been assigned few luns from EMC storage to one of the 3 servers which are under windows cluster, after assigning the luns i can see the luns only in  second server and other first and third servers are not unable to see the luns. If i restart the first server and restart the second server the luns are seen in second server and disappears in first server and if the same i do like restart the second and then third the luns will be available in third server and disappears from second. Can anyone guide me how to resolve this as i need to see the same luns in all the 3 servers. Awaiting for your reply.

Connect with Server Manager results in DISM error

0
0

I'm trying to use Disk Management (and other typical GUI tools) on my new Hyper-V guest. Seems like a simple request?

When I open Server Manager (from the RSAT tools on my Windows 7 PC) and then select the "Connect to Another Computer" option, and try to connect to my new Hyper-V host, I get an error like: "Connecting to remote server failed with the following error message: the ws- management service cannot process the request..."

After Googling for possible solutions, I see someone says:

dism /online /enable-feature /featurename:ServerManager-PSH-Cmdlets

dism /online /enable-feature /featurename:BestPractices-PSH-Cmdlets

but when I try to run these commands on my Hyper-V host, I get an error:

PS C:\Users\ccaughlin> dism /online /enable-feature /featurename:ServerManager-PSH-Cmdlets

Deployment Image Servicing and Management tool
Version: 6.2.9200.16384

Image Version: 6.2.9200.16384

Error: 0x800f0813

DISM failed. No operation was performed.
For more information, review the log file.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

1.) Do I need to successfully run these command in order to use the Server Manager (from the RSAT tool set) or an I just going on a "wild-goose" chase?

2.) How do I diagnose these DISM errors? I think I saw one web site where someone suggested uninstalling/reinstalling DISM. Is that really necessary?

What do you thing about idea of using SATA for Hyper-V?

0
0
 

I’m going to use MD3000i SAN and I need as much space as possible. I can add only 2 MD1000 so when I use SAS 400GB in RAID 10 it could be not enough. I need this for about 80-100 Virtual machines and I just wonder about what I should chose RAID 5 with SAS or RAID 10 with SATA.

I like SATA idea because I can use 1TB drives what will give me plenty of space but I afraid performance issue. What is your opinion about this and what advice can you give me.

Thanks for your help.

Hyper-V Replica with SSL and WAN Acceleration

0
0

Hello Everyone!

I am testing out Hyper-V 2012, specifically the Replica feature using SSL certificates for authentication as my Hyper-V hosts are not in the same domain/forest.  Replication works perfectly fine, however I am trying to test out WAN acceleration boxes, starting with SilverPeak.  The way the WAN acceleration boxes work for SSL, is they essentially become a man in the middle and decrypt the traffic, compress/dedupe it and re-encrypt it then send to the destination.  In theory this should work fine however I am unable to get this working, SilverPeak support is investigating but I wanted to see if anyone here knew if a Man-in-the-Middle approach would work with Hyper-V 2012 Replica.

I should note that I am using self signed certificates, this may also be the cause of my issue, waiting for SilverPeak support to respond.  I have not been able to find any good documentation or white papers talking specifically about WAN acceleration with Hyper-V 2012 Replica and SSL Certs.  

Thanks in advance for any info you can provide.

Cheers,

Remote Desktop Connection hangs on “Detecting connection quality”

Hi,

I have created a Windows 7 VM running on server 2012 Hyper V, installed the integration service and added a VGPU. The issue is Remote Desktop Connection hangs on “Detecting connection quality” and then stops trying. If I set the connection speed manually to LAN (10 Mbps or higher) it connects!

Thanks


Hyper-V R3 VMSwitch 10 Gbps Performance

0
0

Hello,

Question: What is the typical performance on VMSwitch connected to 10Gbps NIC?

Problem: I'm configuring a new Hyper-V R3 cluster with dual 10 Gbps NICs (HP DL380pG8 / HP Ethernet 10Gb 2-port 560SFP+ Intel Adapter) and testing the performance. A direct jperf test between two physical servers is about 9.8Gbps, LACP HASH TEAM 19Gbps, so far so good, but once I create a VMSwitch on top of the TEAM (or the NIC alone) the speed drops to 5Gbps. VMQ is being used (tried disabling VMQ, result almost the same). Tested also without TEAM, same poor performance. I can see one of the cores (NIC RSS start CPU core) being overutilized (during peak Windows GUI freezing), but that should have been handled by VMQ, right? What is your experience? Can you utilize the whole bandwidth on VMSwitch?

Thank you in advance!

How to set up HYPER-V hosts with SMB shared storage

0
0

Hi everybody,

I would need some advice from someone with more experience in this.

I wanted to set up multiple hosts that would run VMs from a common storage, and if possible use SMB based storage for the VMs.

I tried to create a VM on one of our Windows HYPER-V Server 2008 R2, and tried to point the location of the virtual hard drive to a shared folder in the storage.

I received an error:

Failed to create external configuration store at '\\STORAGE1\VMs\TestVM': General access denied error (Virtual machine ID 0x80070005)

The operation failed.

User 'LOCALDOMAIN\snagy' failed to create external configuration store at '\\STORAGE1\VMs\TestVM': General access denied error (Virtual machine ID 0x80070005)

I already gave full access for the user 'LOCALDOMAIN\snagy' to the folder \\STORAGE1\VMs\.

I had some similar general access denied error once, when I tried to restore a VM (I created a new VM and tried to overwrite the VHD file with another one backed up before), and I found an article that fixed it, based on these instructions:

To give the Virtual Machine ID (SID) access to the .vhd or .avhd file, type the following command, and then press ENTER:
icacls <Path of .vhd or .avhd file> /grant "NT VIRTUAL MACHINE\<Virtual Machine ID from step 1>":F
(sorry I couldn't post the link to the article, until my account is verified)

I realized that each VHD file has a special username given access in the NTFS security, for example one is called "NT VIRTUAL MACHINE\7D230D2D-B5AF-48FB-B8B3-1FA350626E47"

I guess when the VM starts, the system is accessing the VHD file through that username.

Probably the user "NT VIRTUAL MACHINE\7D230D2D-B5AF-48FB-B8B3-1FA350626E47" should have access to the location '\\STORAGE1\VMs\' on the storage? But I think that user is a local user on the host and not sure how to assign rights on a folder that is on another computer (in this case STORAGE1). Are there any trust relationships that need to be done between the 2 servers? If yes, how to do that?

I have a couple questions:

- Do I need to configure a cluster of at least 2 hosts for using a shared storage for Hyper-V? Or can I just use independent Hyper-V servers?

- If I need the cluster, would those 2 hosts run the same VMs, or they can each have different VMs running? (If you need to set up VMs per cluster, not per individual hosts, I guess you waste a physical box for the high availability)

- Do I need to purchase additional software, like System Center Virtual Machine Manager (2012)? Or can I do it just by using Hyper-V Manager? (I am wondering if the SCVMM would help to set those security settings automatically, and it could be done manually too using Hyper-V Manager)

- Do the hosts need to be all version 2012 of Hyper-V Server, or can I use a Windows 2008 R2 host too? I heard that Windows 2012 introduced SMB 3.0 but can that be used from aHyper-V 2008 R2 host, or the host also needs to be 2012?

Thanks very much,
Steven


Memory Deduplication?

0
0

I was reading some articles on Windows 2012 recently and came across this one which seems to indicate that Memory Deduplication was something that Hyper-V was capable of. It is an old article (written before 2012 was out), and I have not read of this anywhere else so I think the author may have got his wires crossed. Just wondering if someone could confirm this one way or the other?

Can't RDP to Virtual Machine from Host

I am new to the Hyper-V world and have come across a roadblock. I have Server 2008 SP1 with current updates installed and have added the following roles:

Hyper-V, Network Policy and Access Services, Terminal Services and Web Server (IIS)

My host machine, Server 2008, has a static IP assigined. My virtual machine is getting it's IP from the DSL modem that I am using and is in a different network (192.168.x.x)

My goal is to have the ability to remote desktop to the virtual machine without interfacing with the server. I would like to be able to do this with username and password authentication.

I have tried every combination of network adaptor on the virtural machine and have not been able to access it via remote desktop from my host machine.

Is what I'm trying to do even possible with out assigning a static IP to the virtual machine?

Thank you in advance for any help.

When Start Virtual machine it shown error

When start virtual machine it shows error "an attempt to read or update the virtual machine configuration failed could not initialize" also cannot access the virtual machine folder it show error "You don't currently have permission to access the folder".

Scenario

We have 3 host machine and a IBM san storage. But because of not enough storage we cannot plan for clustering. We pland to use local and san storage bort. So we create some virtual machine in SAN and some in local storage. Our plan is if one hostmachine goes down we add the virtual machine of san to other host machine and it will work. But when we going to test, it shown above error. Can any one help me?

Snapshot - Event ID 19542

Event ID 19542

Cannot take snapshot for 'xxxxxxxxxxxx' because one or more synthetic fibre channel controllers are attached. (Virtual machine ID xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx)

I get this error when trying to take a snapshot of a VM that does have a Virtual Fiber Connection to an HP SAN. The two VM's I am trying to snapshot are a SQL Cluster and I have using the virtual Fiber connection to present the cluster drives. Is there something special I have to do in Hyper-V 3.0 to get it to take a snapshot of virtual machines with Virtual Fiber Connections? I cannot find any details on this.

Thanks,

John


openSUSE 12.03 only gives 800x600 display resolution capability in Microsoft Hyper-V virtual box

0

I have just installed openSUSE 12.03 in a virtual machine box under Microsoft Hyper-V on Windows 8 Pro.

I attempted to change the resolution from 800x600 to something more acceptable, but under Display and Monitor configuration, there are no other options than 800x600.

Microsoft's website says that openSUSE 12.1 is a supported operating system with their Integration Services built in. This should, I would think allow me to utilize the full range of resolutions for the display adapter in my machine. I say this because all my other guest operating system installations work fine with the complete range of resolutions available for my display.

I have also installed Ubuntu 12.04 and CentOS 6.4 as well as Windows XP, Vista and 7 and none of these other installs gives me similar problems.

Is there a known problem with openSUSE in a Hyper-V V-Box with respect to resolution?  I have noticed several similar posts in my web searches, but no good answers that shed light on this problem that is apparently not mine alone.

I am running an Intel Core i3-3220 with an Intel B75 chipset motherboard that uses the Intel default graphics available through that board/cpu on the physical system.
Thank you in advance for any help you can offer


Shared nothing Live Migration Fails at 65%

I have multiple identical Hyper-V hosts (not clustered) with Server 2012 Datacenter on them.  When attempting to migrate machines

from one to the other (Share-Nothing), The will go to 65% and then they will fail.  The error that I get is:

'HYPERV07'. (Virtual machine ID xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx)

Virtual hard disks information transfer failed for virtual machine 'VM1': This

operation returned because the timeout period expired. (0x800705B4). (Virtual Machine ID

xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

Failed to receive data for a Virtual Machine migration: This operation returned because the timeout period expired.

(0x800705B4).

The operation timed out.

Some migrations will succeed, and some will not.  It doesn't matter if I do it with the machines live or shut down.  The Hosts are on the same subnet, in the same domain.  I have the Kerberos delegation configured for the hosts.  Each host has a ten gig interface (active) and a 1 gig interface (standby) in a NIC Team.  I get the same error if I try to migrate them from the GUI or Powershell.  Any help would be appreiated.


HyperV %Guest Run Time Counter in Milliseconds?

0
0

In the HyperV Hypervisor Virtual Processor Counters there is the %Guest Run Time Counter that gives me a percentage value. Is there any way to get a value in milliseconds? I think i could convert it with the knowledge of the time frame for the measurement. My calculation would be: TimeFrame * %GuestRunTime / 100.

Does anyone know how long the timeframe for the measurement is?

My 2008 Standard Server system event logs is fills with event 28 with description below:

Port 'SWITCHPORT-SM-FC5560C9-DCE6-4273-A249-1F6BC894E206-0-1' was prevented from using MAC address 'BC-30-5B-DE-D5-03' because it is pinned to port 'SWITCHPORT-SM-FC5560'.

This server didn't configure any virtual machine. 

Can anyone guide me to solve this problem?

Thanks.
