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

Modify the headless options of the BIOS on a Hyper-V Virtual Machine

Hi everyone,
I am attempting to do something which is (surprisingly) complex using a Hyper-V virtual machine. Using VMware Workstation I have been able to boot from the network using VMware autodeploy. This loads ESXi 5.5 as the operating system. This
works great, but I would like to try to accomplish he same feat using Hyper-V, and I've succeeded. This creates is a nested ESXi 5.5 host.
The process was long and painful, but I have gotten to the point that I am able to successfully boot a Hyper-V virtual machine off the network (legacy network card as the boot device) then load the OS. The only problem is that in order to get it to
boot I need to hit shift + o during the ESXi boot startup, and enter the following line:
ignoreHeadless=TRUE
The problem is that I can't do this manually every time. To understand how to fix this, I first needed to understand what exactly "ignoreHeadless=TRUE" was doing. My understanding is that this has to do with the display, specifically:
"Some systems which have a video display device can be configured to report themselves as headless via the configuration, usually in the system BIOS."
I believe this is my issue, by default a Windows Hyper-V virtual machine reports itself as headless, therefore you need to ignore this configuration on startup or ESXi thinks there is a display error.
My question is, can I fix this from the virtual machine side? Can I modify the virtual machine so that it does NOT report itself as headless?

Hi,
The Hyper-V is the full virtualization technology, and it must installed on bare-metal computer, personal experience, if you are using the WDS with Hyper-V environment to
deploy the Windows system, the performance will lower than the physical computer and you must choose the corresponding method if you have the different environment.

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.

Windows 8 Hyper-V - Virtual Machine Management Service failed to start the virtual machine

I have Hyper-v running on Dell Precision T3600 with Windows 8 OS. I am trying to start a VM (called Windows8VM) to install Windows 8 in the hyper-v virtual machine, but I keep getting the following message:
"Windows8VM" failed to start.
Failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
"Windows8VM" failed to start. (Virtual machine ID D670D3BB-9AE2-0453D-9191-EA6EFC242A9C)
The Virtual Machine Management Services failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
I have turned the hyper-v feature on in the "Turn Windows feature on or off. The BIOS has virtualization enable. Help!!! driving me nuts for a week now.
Nick :(

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 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 .

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!

Service Portal Console Displaying "Virtual Machine Manager lost the connection to the virutal machine"

Hey All,
The issue we are having is that our admins and users cannot use the web console in the Service Portal.
When they right click on the VM and go to console a new tab opens and a message appears where the Console should appear stating: Virtual Machine Manager lost the connection to the virtual machine
We have tried Chrome/Firefox and IE 9/10/11. With Firefox and Chrome it just tries to load the Console Session.
Wonder if the community can provide some insight.
Thanks

Hi Boris,
Are your hosts Hyper-V hosts? Console connect makes use of an ActiveX control and users will need permission to install the ActiveX control.
This ActiveX control will then connect directly to the Hyper-V host that is running the virtual machine, which requires the client computer to have connectivity to the Hyper-V hosts and the user will need permission on the Hyper-V server.
Kind Regards,
Richard

Randomly losing network connection over wireless

Shortly after installing the 10.4.5 software update, my G4 iBook with built-in Airport Extreme card has been losing connection with increasing frequency. Built-in Ethernet use is unaffected. I'm calling this problem thrash-and-drop.
1. When it's losing signal, processor activity goes through the roof. I had Activity Monitor running during a thrash-and-drop. kernel_task CPU consumption goes from under 1% before the event, to over 80% during the thrashing, and back under 1% after the thrashing stops. The activity is so bad the cursor can't be controlled: using the track pad sends the pointer all over the screen or nowhere at all.
2. This has been observed to occur with two different wireless base stations: A Linksys WRT54G and an older SMC 802.11b router. Either router is within 10 feet of the computer. Only one is running at a time. There are no other base stations in range.
3. Another iBook G4 (OS 10.3, Airport Extreme card (not built-in)), sitting next to it, shows no change and its wireless behavior is unaffected.
Initially, this seemed more likely to happen when Safari was loading Flash-heavy pages. And after thrashing and dropping a connection, it was able to reconnect after either a reboot or a five minute sleep. Currently, it can't connect to a base station for more than a minute. Most recently, it thrashed and dropped while I was selecting the base station to use. This is true regardless of the application running. In fact, it will thrash-and-drop when there are no user applications running at all, after a fresh reboot.
I've tried the following things to address the problem. None have affected the thrash-and-drop problem. Admittedly, most of this is random:
1. Back up and delete network preferences in /Library/Preferences/SystemConfiguration
2. Turn off IPv6 in System Preferences/Network
3. Back up and delete network preferences in ~/Library/Preferences (com.apple.NetInfoManager.plist and com.apple.NetworkUtility.plist)
Has anybody else seen this problem? I want to blame it on the 10.4.5 upgrade but I haven't seen anybody else complaining about 10.4.5 doing this to them. If there's something I can do to fix this in a software setting, I'd much prefer that to yet another roadtrip to the Apple store.
1.33 GHz G4 iBook Mac OS X (10.4.5)

Hi!
I have the same problem of randomly losing network connection over wireless, though mine is hardly related to surfing.
I have an external storage drive in which I use for backup of my stuff, and I access the drive via my modem, using the airport. Of late, I noticed that when copying files from my iBook to the external drive, the connection would suddenly drop before the transfer is completed. This began to occur with increasing frequency, particularly when transferring large files.
I have since abandoned wireless connection, and reverted to my trusty cable. Still, I admit that I'm really curious about the cause of the apparent lack of reliability with my wireless connection. Has it something to do with the airport?

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?

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 "

BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network

I'm trying to create an "ExtraLarge" VM with multiple NICs. The New-AzureVM returns the following error:
BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network
interfaces are not supported in the same deployment, also a virtual machine having no secondary network interfaces
cannot be updated to have secondary network interfaces and vice-versa.
But I have no other VMs. Or at least I did and then deleted them and all their disks. The service has no deployments (either staging or production).
Why is New-AzureVM complaining about a mismatch of VMs with and without secondary network interfaces when no other VMs exist?
I have tried many things to fix this, including the deletion of ALL of my resources. I have deleted and created the service many times, both with an affinity group and without. I have a screen print of the -debug output if your interested.
Thanks for the outstanding help.

Hi Ron,
IMPORTANT NOTE: Please do not post the CONFIDENTIAL DETAILS ever on the public forums, this is HIGH RISK action.
Please send an email with your contact details to my email
[email protected] so that I guide you on steps which help you come out of the current scenario. Thank you for understanding.
I suggest you to create a new VNET and new VM with cloud services. Create Multiple NIC VM. Let us know the results.

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 .
