Firewall blocking access to Hyper-V Virtual Machine. Please hep!

Hi there, I hope this is the right spot for this. Allow me to explain the setup we have. We have a server with Hyper-V installed and a VC made for a DC for a small domain we have. I was able to remote into the new DC, and our exchange server
was picking it up as a DC. So far so good.....
Now, here's where we seem to have a problem. We Installed 'Symantec Endpoint Protection' As we have this on a few servers, we had a set of settings for servers. (I didn't set this part up) Now. the problem we are having is that it seems the end point protection
on the Hyper-C Host is blocking connections from Exchange/other computers (access shared folders and logging in). What can i do to resolve this? Connections seem to be fine, (Exchange will pick up the the DC, and i can access shared
folders) when i disable the firewall and network threat protection on the Hyper-V Host.
Our Exchange server is 2010
We are using Server 08 R2
Can someone please advise me on how i can get this resolved, so i don't have to leave the server with Hyper not behind a firewall or network threat protection.

Hi,
I am Chetan Savade from Symantec Technical Support Team.
There was a known issue between SEP and Hyper-V traffic. It's been resolved in the latest release of SEP. If not using the latest version upgrade to the latest version can be a possible solution.
SEP 12.1 RU4 MP1a (12.1.4104.4130) is the latest verison.
HyperV traffic was blocked with Symantec Endpoint Protection Firewall enabled
Fix ID: 3181006
Symptom: The Symantec Endpoint Protection firewall blocks HyperV traffic.
Solution: Modified the loopback packet processing in the Teefer driver.

Windows 10 Technical Preview - There is NO "Hyper-v Virtual Machine Management" service???

hi all,
There's no such Windows Topic as "WTP Virtualization", so I post this thread here, a somewhat "VIRTULIZATION" related.
I installed WTP (not server) x64 enterprise 9879, and added "Hyper-v Management" feature (management only, without Hyper-v core) in Control Panel. Then I found that there was no "Hyper-v
Virtual Machine Management" in Services panel, and there was no such file "c:\windows\system32\vmms.exe". Therefore I cannot connect to Windows Server 2012 R2 Hyper-v through WTP Hyper-v Manager.
I confirm the reason is what I state above. Firewall rules are properly configured on both Hyper-v server and WTP. I also used hvxxxx.wsf to configre anondcom to be "allow". When
I connect WS 2012 R2 through WTP, Hyper-v manager on WTP says "Please confirm VMMS server is running".
Is it a bug, or lack of implementation, or restriction of preview edition?
Any suggestion is appreciated! Thanks!

Okay, I turned off hyper-v, went to bios and enabled Intel TXT(LT-SX) Configuration. Made sure that both Virtualization and VT for Direct I/0 are on. Next, I turned on Hyper-V and I create a brand new Virtual Machine call Windows8 and had
the DVD point to Windows8 ISO file on hard drive. When I clicked on start, it stayed in the Starting status mode for about 5 minutes. Then of course it failed. I looked at the Hyper-V-VMMS log and here is what it output:

Hyper V Virtual Machine Creation

While we try creating a new virtual machine for our windows phone application, we are facing the following error.
-Failed to add device 'Virtual Hard disk
-Hyper V virtual machine management service account does not have permission to open attachment.
ERROR: General access denied error(0x80070005)

Unblock whatever it is that you downloaded.
Check that your antivirus software is set with the proper exclusions.
I don't recall anyone reporting this error before - as the installer for the phone emulator generally takes care of the machine creation and permissions.
I can only guess that you are attempting to duplicate the phone emulator VM. If so, use Export and Import.

Hyper V virtual machine randomly loses network connectivity

I have an extremely odd issue happening on one of my Hyper-V virtual machines. For no apparent reason and completely sporadically my virtual machine will lose all network connectivity. It is a linux Vyatta firewall image. Digging through
the logs shows nothing at all when the machine actually goes offline, but when the machine starts back up I just get a Warning stating the network driver on my virtual machine loaded but has a different version from the server. Server Version 3.2 Client
version 0.2
I've ran the integrated services setup disk and nothing has fixed this. When the VM loses connectivity it is for no apparent reason, sometimes at 1am sometimes at noon, just happens. The only solution is to reboot the VM to bring it back online.
Has anyone else seen this or know of a fix for it? Its starting to slowly drive me insane!
Hyper V Server - Windows Server 2008 R2 - Hyper V Manager Version 6.1.7601.17514
VM - Linux Vyatta Core 6.3

I tried downloading new integrated services disk setup for linux, but Vyatta wouldn't work with it so I was kind of stuck there. And not sure where you are talking about changing NIC to legacy at. I did disable some TCP chimpney settings as
per an article I found, but not sure if it will fix it or not. Sometimes the machine will stay on for a month before losing network connection and sometimes it comes in spurts and happens like 3-4 times over a couple days. Its really odd

Error Creating VM on 2011 iMac - The Hyper-V Virtual Machine Management service encountered an unexpected error: The remote procedure call failed. (0x800706BE).

I am running Hyper-V in Windows 8.1 on a late 2011 27 inch iMac. Whenever I try to create a virtual machine I get the error below and Windows warns that it will restart in 1 minute. I tried a clean install of Windows, but my PC still crashes ever
time I try to create a VM. I was able to successfully use Hyper-V in prior versions of Windows on this same PC. Any clue as to what is going on? A driver? Windows 8.1? Mac Hardware related?
I see the following two entries in event viewer but have no other clue as to what is happening:

Hi CharlesPool,
I am assuming that the win8.1 is in-place updated from win8 .
Maybe you need to check the state of hypervisorlaunchtype .
If it is off , please run command " bcdedit /set hypervisorlaunchtype auto "

Hyper-v virtual machine management in status stopping

Hello,
I had a problem with one vm showing status backing up.
I read on TechNet that restarting the hyper-v virtual machine management service would solve the problem.
I have tried to shutdown the service but it now says status stopping...
How long time does it take to shutdown the service? Is there anything I can do to hurry it up?
ps. I have production vm running on the host that I can't take down...
Regards
Roger

Hi Roger,
I also tested in my lab to disable that service forcibly ,then I found that it will leads the VMs to unexpected shutdown .
Based on this ,it seems that restarting the host is necessary .

How to connect USB external Harddisk to Hyper-v virtual machine

Hi,
We are running hyper-v server 2008 R2, we have external USB harddisk connected in hyper-v Manager, we are not able connect this USB to virtual machine.. is this option is available in hyper-v? if no is there any document from microsoft stating the same?
Regards
Asha

Hi,
Unfortunately, USB is not supported on a Hyper-V virtual machine. You can perform the following suggestions:
1. Offline the USB hard disk on the Hyper-V host machine and connect it to the virtual machine as a pass-through disk(if the USB hard disk is support)
For more information, you can refer to:
Configuring Pass-through Disks in Hyper-V
http://blogs.technet.com/b/askcore/archive/2008/10/24/configuring-pass-through-disks-in-hyper-v.aspx
2. You can also use some USB over Ethernet application.

Hyper-V Virtual machine disappeared

Hello,
I am running Windows Server 2008 R2 SP1. I have the Hyper-V role installed with to virtual machines. I rebooted yesterday after windows updates loaded and now one of my virtual machine have disappeared. I have run through hours of technet
forums trying to find the answer and have come up empty.
I checked ProgramData\Microsoft\Windows|Hyper-V\Virtual Machines and the symbolic link is gone. I tried to recreat it using the mklink command, but every time I recreate the symbolic link to the .xml it comes back as a link to a file folder.
I checked the acl on the virtual machine .xml on my D: drive and the GUID SID is missing. I also tried to add it back via the iacls command but it doesn't seem to exist.
After all that, I decided to recreate the entire virtual machine, but now I can't create virtual machines. I get teh following error:
"Failed to create external configuration store at 'folder path': A required privilege is not held by the client. (Virtual machine ID 0x80070522)"
After that error I opend azman.msc and verified that the initalstore.xml has the administrators group in it.
I do not know what else I can do from here. Any help would be appreciated.

Restored Hyper-V Virtual Machine Snapshots by error

Hi Everyone,
We are facing a disaster !!, One of our team restored an old Hyper-V Virtual Machine Snapshot by error which erased our recent databases. So i'am wondering is there a miracle to restore that data. Like we can flashback to 3 hour later.
Help is very appreciated !!
Yasser Emad

Hi Yasser,
Unless a snapshot was taken just before reverting back to the old snapshot, or a backup exists, I'm afraid I don't believe there is.
Is this a checkpoint from failover cluster manager or SCVMM?
Kind Regards

Hyper-V Virtual Machine manager

When using the Hyper-V Virtual Machine Manager and Connecting or Viewing using RDP is there any way to configure the app to span multiple monitor, (3) would be great

Hi Sir,
I'm afraid you need to use "mstsc.exe" to RDP to that VM instead of "vmconnect" in hyper-v manager .

Cant create replica and Hyper V virtual machine management service slow shutting down

Hi,
I cant create replica and Hyper V, I go through the process and all looks good it even starts to create the hard disk but it stops at 4096K and the wizard just keeps going.
The management console is also slow or wont load virtual machines - stuck on loading virtual machines
The Hyper V virtual machine management service slow shutting down over 30 minutes on re boot of Hyper V core 2012 R2
Any ideas ?

Hi Sir,
I assume that you have a standalone hyper-v server 2012R2 and you are using hyper-v manager to manage the hyper-v host .
Which system you are using to manage hyper-v host , win8 or win8.1 or other ?
Have you created VMs on the HOST ?
I would suggest you to create vhd or someother operation on hyper-v host directly to check the result .

Create Protection Group Hyper-V Virtual Machines Not Listed

Hello,
We are in the process of testing DPM 2012 R2 and we are trying to backup our Hyper-V virtual machines on both cluster hosts and stand-alone Hyper-V hosts. We have deployed the DPM agent to all cluster hosts and the stand-alone hosts, but when we go
to create a protection group, we do not see Hyper-V Virtual Machines listed under "HyperV". We are expecting Virtual Machines to show up as shown in Step 7 of this guide: http://blogs.technet.com/b/kevinholman/archive/2013/11/07/dpm-2012-r2-quickstart-deployment-guide.aspx.
We have DPM 2012 R2 UR4 installed and Hyper-V role is enabled on the DPM server.
Is there something extra we need to do or something we are doing wrong?
Thank you.

Gleb,
Thank you for your help. For our cluster, we realized we weren't seeing any VM's under the Cluster Node because an agent was not installed on our of the Hyper-V hosts in the cluster. As for the stand-alone Hyper-V host and the cluster node listing
within the "Create New Protection Group" wizard, it looks like MOST of the VM's have the "Backup Using Child Partition Snapshot" option, but no longer show as "Online" or "Offline". I believe this is due to the
way the Hyper-V backups are done w/ DPM which was changed either in R2 or one of the Update Rollups.
