Connect to Virtual Machine Fails
Hello, I have a quick question about authentication in SCVMM console. We use non-privileged account on our local workstations where we use our SCVMM consoles (which has no access to SCVMM). When we open our console, SCVMM prompts for credentials, we provide
it our privileged account and get logged in. This works great until we try to connect to the console of a VM. The system tries to use our non-privileged credentials to open the console, which fails with Access Denied. Is there anyway to make SCVMM use
the same account that we logged into the console as to also open the VM consoles? Thanks.
This seems a bug wherein VirtualMachineViewer.exe process launches in the same security context with which you logged onto your workstation
Possible workaround is to create a new Definition that only allow viewing / receiving input and output from the Hyper-v virtual machines , To do this
Start Authorization manager (azman.mmc) on each Hyper-V hosts (in your cluster or host groups in SCVMM)
Open the InitalStore.xml document located within \ProgramData\Microsoft\Windows\Hyper-V\
Expand out InitialSTore.xml, then Hyper-V Services, then Definitions.
Create a new definition ,specify the appropriate name and Click Add | Move to the "Tasks" section. | Click on the "operations" tab and select below given options to
"Allow input to VMs & Allow output from VMs & View VMs configurations"
Hit OK to comeback to main definition page , here expand out Role Assignments, and right click the new definition, select "Assign users and Groups", then select "From Windows and Active Directory"
Add the users that need to open the console only for viewing VM's and opening the VM Viewer console.
Hopefully you will achieve what you expects :)
Thanks

Client Hyper-V "Cannot Connect to Virtual Machine"
I'm trying to run Client Hyper-V on my Windows 8 Pro machine. I was able to successfully install the service, and can create virtual machines and hard disks on my local system. I can even start them, and see boot activity via the preview window in the MMC.
I cannot, however, connect to any machines from the local system: when I do, it hangs on "Connecting to <machinename>" for 30 seconds before it pops up with the dialog:
"Cannot connect to virtual machine. Try to connect again. If the problem persists, contact your system administrator."
Obviously, because this is Client Hyper-V, I am the system administrator, so I scour the Internet to solve my problem. I see solutions related to firewalls, administrative permissions, a few other things, and nothing has worked. I also tried creating
a virtual machine on a Windows 8 Enterprise system (which can connect to it just fine) and export it for the Pro machine to import, and I still cannot connect to it, whether the VM is registered in place or copied to the host.
Some other notes:
- None of these systems has an OS installed - two locally created ones either had no boot or booted off a Linux LiveCD, and the exported one attempted to do a PXE boot. Thus, I cannot attempt to link via Remote Desktop since the computers have no names
- Hyper-V has some other quirks on my system as well: in order to stop a virtual machine, I have to end the vmwp process - which restarts the machine - and then stop it from the console within a few seconds. Otherwise, it hangs in the "Stopping"
state. In addition, none of the buttons on the side of the MMC work, but that occurs over all of MMC.
- No events show up in the Event log when a connection fails
- I am an admin on the Pro machine and have permissions to connect to machines and operate the management viewWhen you checked the event log’s what sources did you check?
Can you verify there are not any relevant error/warning events under the following sources:
Applications and Services Logs
Microsoft
Windows
Hyper-V-VMMS
Admin
Operational
Hyper-V-Worker
Admin
Operational
If not we should enable some additional logging if possible to see what is going on.
Shutdown any running VM’s
Close all of the Hyper-V UI
Stop the VMMS service (net stop vmms)
Enable Analytic logging for the VMMS and Worker Process (see below)
Enable UI Tracing for Hyper-V Manager and VMConnect (see below)
Start the VMMS service (net start vmms)
Open Hyper-V Manger
Restart the VM
Attempt to connect (try two or three times)
Gather Logs (see below)
Disable Tracing (see below)
Enabling Analytic Logging For the VMMS and Worker Process
Open the Event Viewer
From the menu bar select View -> Show Analytic and Debug Logs
Navigate to the Hyper-V logs and Enable the Analytic Channels
Applications and Services Logs
Microsoft
Windows
Hyper-V-VMMS
Analytic
Right Click -> Enable (yes if a pop up asks about enabling the logs)
Hyper-V-Worker
Analytic
Right Click -> Enable (yes if a pop up asks about enabling the logs)
Enabling UI Tracing
Create a new text file named “VMClientTrace.config” in the "%appdata%\Microsoft\Windows\Hyper-V\Client\1.0\” folder
Copy the following XML text into that file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<Microsoft.Virtualization.Client.TraceConfigurationOptions>
<setting name="TraceTagFormat" type="System.Int32">
<value>3</value>
</setting>
<setting name="BrowserTraceLevel" type="System.Int32">
<value>71</value>
</setting>
<setting name="VMConnectTraceLevel" type="System.Int32">
<value>71</value>
</setting>
</Microsoft.Virtualization.Client.TraceConfigurationOptions>
</configuration>
Save the file.
Gathering The Logs
The Analytic logs will be in the analytic folder (you often have to refresh or select another source then analytic again to see them)
The UI trace Logs will be in %temp% (sometime back one directory i.e. %temp% = “C:\Users\taylorb\AppData\Local\Temp\2” for me but the logs are at “C:\Users\taylorb\AppData\Local\Temp”
Disabling Tracing
To disable Analytic Tracing just right click on the analytic sources and select disable (same as enabling)
To disable UI tracing just delete the “%appdata%\Microsoft\Windows\Hyper-V\Client\1.0\VMClientTrace.config” file.

JInitiator 1.3 Fatal Error Attachment to a running Virtual Machine failed
We are running forms 9i from 9ias R2. We have an outside client trying to access the application from a machine with Windows XP. They receive the following errror after downloading the Jinitiator 1.3.1.9: JInitiator 1.3 Fatal Error - Attachment to a running Virtual Machine failed. As we are using Windows 2000, we have not come across this before and I find nothing on Metalink.
Has anyone else had this problem? If so, do you have a solution?Hi,
whatever browser you are running, during installation of the Browser (Netscape 7.x) or IE (postinstall) you decided to make teh Java Plugin 1.4 your default JVM. This means the VM is started when JInitiator loads which then leads to this collision. Disable Java Plugin as a default VM and it shoudl work fine.

Attachment to a running virtual machine failed
I get the error message "Attachment to a running virtual machine failed" when trying to instantiate my active x bundled java bean.
The steps I took to create it are:
javac Person.java
jar -cvfm PersonBean.jar person_manifest Person.class
set JRE=D:\Applications\JavaSoft\JRE\1.3.1_01
set classpath=%JRE%\lib\rt.jar;%JRE%\lib\jaws.jar
java sun.beans.ole.Packager
Then I answered the questions on the packager.
When I try to create the bean from inside my application, I get an error dialog with the title "Java(TM) Plug-in 1.4 Fatal Error".
When I try to create MSCal.Calendar in my application, all is well.
Anyone know what is happening?If you run the packager, try not to register the
newly created type library (*.TLB) immediately,
but let the packager create the registry instructions
(a *.REG file).
Look at the *.REG file and check all references to
virtual machines. Since you are using the packager
from 1.3.1, probably the virtual machine (path for beans.ocx etc) points to the 1.3.1 JRE instead of the
1.4 plugin.
Make sure, all references to the virtual machine are
linked correctly to 1.4 and reregister your TLB.
Hope that helps and please let us know if you were
successful, as this would indicate that indeed, beans
packaged with the packager from 1.3.1 can run in the
1.4 plugin. Sylvia -

I am unable to create new VMs as well.
I have already run
sfc/ scannow
DISM
Already Tried disabling the antivirus
Upon using wbemtest and connecting to root\virtualization, I am able to click Enum Classes > Recursive
Kindly suggest how to get HyperV working please. Any help (short of reinstalling /resetting windows) would be much appreciated.
Warm Regards,
Dr Vivek GuptaHi,
The key point would be this:
The Virtual Machine Worker Process has lost its connection to the root\virtualization WMI namespace: General access denied error (0x80070005).
Please open MMC, add Component Services snap-in:
Component Services -> Computers -> My Computer -> DCOM Config -> Windows Management Instrumentation -> Right Click, Properties -> Security “Launch and Activation Permission” -> Edit -> gave Authenticated Users
Full Control
Check the result.

[Forum FAQ] Resolve virtual machines fail to start issues
After you restart the Hyper-V Host server and the guest virtual machines, you may encounter the error:
An error occurred while attempting to start the selected virtual machines(s).
Here are three common issues.
Issue 1
On a Windows Server 2008-based machine that has the Hyper-V role installed,
or on a Microsoft Hyper-V Server 2008-based machine, you encounter the following:
• When you try to connect to a virtual machine, error occurs:
Cannot connect to the virtual machine because the authentication certificate is expired or invalid. Would you like to try connecting again,
• When you start a virtual machine, error occurs (Figure 1):
An error occurred while attempting to change the state of virtual machine
‘VMname’
'VMName' failed to initialize.
Could not initialize machine remoting system. Error: ‘Unspecified error’ (0x80004005).
Could not find a usable certificate. Error:
‘Unspecified error’(0x80004005).
Figure 1: ‘Unspecified error’ (0x80004005).
Cause:
This issue may occur if the Hyper-V Virtual Machine Management service (VMMS) certificate has expired.
Solution:
Install the Hotfix.
You cannot connect to a virtual machine when the Windows Server 2008 Hyper-V VMMS certificate has expired
http://support.microsoft.com/kb/kb967902/en-us
Workaround:
Follow the steps below to generate a new certificate.
1. Shut down or save all virtual machines.
2. Restart the Hyper-V VMMS.
3. Start the virtual machines.
Note:As the Hyper-V VMMS certificate is valid for one year, the update has to be applied to prevent this issue from occurring in the future.Issue
2
If there is no enough system resource, this error may occur (Figure 2) and you will receive Event ID 3040.

Troubleshooting:
You need to check the following:
1. Permissions of the configuration files, memory files and all VHD files.
2. Prior messages in the event log.
3. Available RAM on the system.
4. Free disk space for the storages of the memory files and expanding virtual hard disks.
In addition, if you are using the VMMS, please restart the VMMS service.

Oracle Linux virtual machines failing to boot
We have 2 oracle linux virtual machines on one host machine, both running Oracle Linux release 6 update 2 for X86_64. Both were built identically with oracle 11 installed on them. Both machines were working ok until this morning when the host machine rebooted. After the reboot, the virtual machines now hang during the boot process. The login prompt never comes up. The database does not start up on both machines. The machines are up enough that I could putty into them. In startup.log, the following is listed for the two machines. One is named demo, the other test.

I'm running Windows Pro 8.1. Virtualization is enabled in BIOS. Account is in Admin, Hyper-V, RDP groups. I open Hyper-V manager. Create a new Virtual Switch (internal) and name it. Then create a new virtual machine - name it, place it in a folder under
C:, Specify Generation (tried both 1 and 2), startup memory 512mb not dynamic, Lan- select the virtual switch created earlier, create an vhdx hard disk, and install the O.S. from an ISO on C. Creates the new VM under Virtual Machines.
I select the new VM, click connect, then start. A window opens with the new VM on server and says it's connecting to it and it's status is Running. In the Hyper-V manager in the New Virtual Machine pane (bottom pane) it shows a image that
appears to have a login screen. The VM window that displays the "Connection to" eventually throws an error : Virtual machine connection: Cannot connect to the virtual machine, Try to connect again. contact your admin, Try again etc. selecting connect
eventually errors out with check integration services etc. I've read the logs, there are no errors. When I try to shut down or turn off the vm it doesn't respond. I've configured this before on different boxes. It's the work environment for the MCSA 70-462
training kit Preparation. any direction would be greatly appreciated.That is correct. This has been well documented.
The WMI namespace changed. 2008 and 2008 R2 now of the v1 virtualization namespace. 2012 knows of both v1 and v2. And 2012 R2 only knows the v2 virtualization namespace.
That said, there is more to this.
2008 management console only knows 2008 features. So if you connect it to a 2012 server to manage the 2012 server, you cannot manage any of the features released with 2008 R2 nor 2012.
So, take this second point, mix it with the first point and I recommend that your management server / client release matches the release of the Server you are managing.

Cannot connect to virtual machine in hyper-v
One of our servers got corrupted and I managed to salvage the VHDs of the two VMs we were running on it. The server was Win Serv 2003 and was running virtual server.
Now I'm trying to import the VHDs into Hyper-V on a newer 2008-R2 server and while the VM seemed to import just fine I cannot connect to it. Each time I try it gives me this error:
"Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator."
I think the issue could be that the VM was apart of a domain and now I'm trying to connect with a server that is on a different domain and has a different DNS.
Is there anyway I can save this VM and not have to start from scratch?Hi,
Is Windows Server 2003 is a DC? Is there a backup DC for Windows server 2003 if it is a DC?
If you logon with domain account, you cannot connect to the origin domain if you don't have DC or you haven't restored DC. To fix this issue, you can restore Windows 7 to the point when windows 7 doesn't domain if you have such a restore point.
Also, if you have DC and still connect to the virtual machine, i recommend you to log on the Windows 7 client with local adminstrator , disjoin from origin domain, then re-join the domain. At last, it will work well.

Hi,
I got this error on one of the VM (web server) backed up usng HYPER-V 2008 R2 and when I looked up, there is an microsoft hotfix for the same issue.
Microsoft KB Hotfix:
A backup of virtual machines fails when you use the Hyper-V VSS writer to back up virtual machines concurrently on a computer that is running Windows Server 2008
http://support.microsoft.com/kb/971394
But, the VM (web server) is running Windows 2008 R2 - SP1.
Hotfix says - To apply this hotfix, your computer must be running one of the following operating systems:
Windows Server 2008
Windows Server 2008 Service Pack 2 (SP2)
Does it mean it does not apply to Windows 2008 R2 | SP1 ?
When I checked the :
Swprv.dll version, it was higher than the one mentioned in the hotfix.
Thanks for any help.
-AshwinHi Ashwin,
I am assuming that the VM(web server) is using SQL .
Please try to disable SQL Server VSS Writer in services.msc , then retry WSB again .
Hope this helps

Connecting Virtual Machine to physical Domain Controller
Hello,
I have a Hyper-V environment set up. My virtual machines are on my domain controller. I would like to connect these virtual machines onto the domain controller I am hosting them on. I have tried however I always get the error saying the domain controller
cannot be contacted.
Thanks in advance,
Maksim Richardshttp://blogs.technet.com/b/jhoward/archive/2008/06/16/how-does-basic-networking-work-in-hyper-v.aspx is a good article that explains the basics
of Hyper-V networking. What you are describing generally comes down to understanding the basics and getting your virtual networking switch(es) properly configured. When it comes to networking, IP is the same whether using physical or virtual machines.
You have to ensure that you have the proper paths in place that allow the communications to take place.
As for support of Hyper-V on a DC, I've not seen that it is unsupported. Bad idea? Yes. Recommended practice? No. Would I do it? No. Should it work? Absolutely. Supported? I haven't seen a Microsoft
statement on that.

How to transfer files from virtual machine to host machine
Hello,
I want to know how to copy files from virtual machine o host machine while the virtual machine running. I can't share files from virtual machine because i am just studying for mcsa in company computer. I can't connect my virtual machine to same network so
i'm using a different ip range and i created a internal network switch for my virtual machines in hyper-v. Please give me a best solution for my studies.
Regards,
Ashane Deshapriya.
Ashane Deshapriya ( MCP )Finally I got the solution...
Here is how you can share files between a Hyper-V host and any virtual machines running on that host.
If you've used Microsoft Virtual PC or Microsoft Virtual Server, you'll have enjoyed the fact that you can copy and paste between a virtual machine and those platforms. This doesn’t work with Hyper-V however—you can't copy/paste between a VM and the Hyper-V
host.
The workaround is to do the following:
1. On your Hyper-V host, create a shared folder and assign Change permission to Everyone.
2. On the virtual machine running on the host, open the Network and Sharing Center and enable File and Printer Sharing.
3. On the virtual machine, click Start and type \\host_name\share_name where host_name is the name of your Hyper-V host and share_name is the name of the share you created.
4. Press ENTER and an Explorer window will open in the VM showing the contents of the shared folder on the host.
5. You can now copy files from the VM to the host and vice versa as needed.
Regards.
