I've recently moved a Virtual machine from a server to another one.
Both the servers are running Windows Server 2012 R2 as the guest host.
The generation 2 VM run almost perfectly, but it doesn't recognize the network adapter.
Integration services are updated (if I try to re-install it it says they are already updated and doesn't let me repair it).
On device manager I see the exclamation mark left to the adapter.
If I let it search for drivers in C:\Windows it says that the "Network adapter for Hyper-V" is found, but it isn't digitally signed, so it won't be installed.
Anyone could help me making this adapter work?
I couldn't figure out how to remove and re-install integration services either...
Ok, I found a solution.
I had to Disable Driver Signature Enforcement in the advanced boot options.

Here is my working context;
no internet (I use my company's intranet)
Linux CentOS 7.9 remote server with my source files
PhpStorm 2021.3.2 on my development PC
My wish is to develop on my PC on remote sources. Your new JetBrains Gateway solution seems to meet my expectations on paper.
However, in practice, I have the impression that it is not possible to use this solution without internet ? Indeed, the connection process stops on this failure:
Looks like your solution is trying to download an IDE client to install on my machine. Which from my point of view is a weird behavior because I already have a client to install on my machine: PhpStorm. Why not use my PhpStorm client already installed on my machine ?
Thank you for your reply
The "Jetbrains Client" mentioned in the error message is not for your local machine, but for the Linux server:
Once the IDE version and project directory are selected, Gateway will download the IDE to the remote server, unpack it, and launch it with your project loaded.
It acts on the remote server as a "backend IDE" to which the client on your local machine connects:
The JetBrains Client runs locally and provides the user interface for the IDE backend.
You would not even require the full PHPStorm IDE, the Jetbrains Gateway is a standalone app that comes with a "thin client" that can connect to the backend IDE:
This whole process is managed by JetBrains Gateway, a new, compact, standalone app that provides everything you need to get started with remote development. Since it’s standalone, it’s the only thing you need to install locally to start working and is ideal for less powerful laptops and in cases where a full IDE install isn’t desired.
See https://blog.jetbrains.com/blog/2021/12/03/dive-into-jetbrains-gateway/ for a more detailed look at how it works.
To answer your question: it is not possible to use Jetbrains Gateway without an internet connection.
I am using worklight 5.0.6 in Eclipse juno on Windows 7.
I made a simple form filling app. I am deploying this app on my PC, Making it a worklight server. I am accessing it from the instance of the app which is running on my phone.
It works fine as long as my Phone and PC are on the same network, that is, on local LAN.
But when I change the network to Internet, the app is not able to connect to the worklight server - which is, again, my PC.
My Questions are:
Where should i put the public IP address to access the worklight server?
Should i change the worklight version to make it work?
Also, I read solutions that you gotta run the "Build and deploy on remote servers" But i couldn't find the option for it, what i found was "Run on Server"
But i really don't know how to proceed after that.
Should i change the worklight version to make it work?
You should upgrade your Worklight from 5.0.6 to a later release regardless of the connectivity problem - it is a very, very, old release.
Also, I read solutions that you gotta run the "Build and deploy on
remote servers" But i couldn't find the option for it, what i found
was "Run on Server"
This is not related to what you are facing. This option is meant to be used as you prepare to move the development environment (the developer workstation) to other environments, such as QA, UAT and Production. This feature is meant to change the connectivity settings in the application. Again, not relevant for you at this time.
But when I change the network to Internet, the app is not able to
connect to the worklight server - which is, again, my PC.
The problem you are experiencing is expected. There is your PC, which acts as the local server, connected to the Internet via your router. And there is the device, also connected to the same network via the router.
As you disconnect the device from the local network, it is no longer able to connect to the server, which is still in the local network.
If you want that work still, you'd need to setup a server with an external IP address that your device will attempt to connect to, and be able to route the request to the Worklight Server... in short, in a development environment it is expected that you will be on the same network.
I have been trying to setup a Win7 VM on Hyper-v that connects to the internet through my Win 8 host machine.
I can't seem to figure out why the VM can't ever get passed limited connectivity. Any ideas?
NO sure why but all I had to do was Disable/enable the vEthernet adapter and everything worked great!
Check that you have a Virtual Switch with an "External Network" using the Virtual Switch Manager.
The other network types offer VM isolation. If your VM is on an "Private Network" it can only talk to other VMs on the server. The "Internal Network" allows VMs can talk to other VMs and to the host.
In contrast, an External Network allows the VM to contact machines on the network that the host is attached to.
I worked on this issue for a while myself after upgrading to Windows 8.1 and losing connectivity. Added and removed the adapter to no avail. The solution was to upgrade the VM's Integration Services.
I had the same issue because my DHCP settings on my guest VM was setup wrong.
So check the DHCP setting if they are on obtain automatically.
Control Panel\Network and Internet\Network Connections
Network adapter properties -> Internet Protocol Version 4 (TCP/IPv4) -> Properties ->
Obtain DNS server address automatically
I have had great success with Hyper-V and windows 8 and windows 10 virtuals using external switches with a Windows 8.1 host. Unfortunately I could not get the external switch to ever work on windows xp virtual running under Hyper-V. Instead, after reading a lot of sites/suggestions, I followed this guide to bridge an internal virtual switch (with Hyper-V legacy network adapter for XP) to the host wifi. I hope this saves someone else some time when working on an XP virtual.
Using Hyper-V with a Wireless Network Adapter
I have installed windows phone 8 SDK and tried running a simple app which embeds a WebBrowser on a page. When I try to run the app in emulator the emulator does not get internet connection. It displays an error message saying "You don't have permission to modify internal Hyper-V network adapter settings required to run the emulator". Im sure my login has admin permissions. My machine is 64bit, hyper v is enabled and Hyper v manager is running, hardware virtualization is enabled in the BIOS settings, DHCP is enabled and its connected to a wired network. I have checked all the system requirements. What ever I do it keeps on giving the same error message. I setup everything in a different machine and tried running the app in that machine. The same error message is displayed in the that machine also. Can anyone tell me how to get it working.
DHCP is enabled and its connected to a wired network
Can you run ipconfig /all on your host machine and post it here please?
seems you have problem with your DHCP or maybe multiple DHCP and conflict.
You need to add your user account as a member of the "Hyper-V Administrators" group on the machine.
Detailed steps:
Hit Windows key + Q and search for "local users and groups". Change the search scope to "Settings". Click "Edit local users and groups".
Expand the "Groups" section. Right-click on "Hyper-V Administrators" and select "Add to group".
Add your user account.
Some connection tools on the host can have negative effects when used with the emulator; I found having cisco VPN client installed on the host prevented the emulator from finding the internet. Other VPN clients may have similar side-effects. I simply uninstalled cisco (the inbuilt windows VPN is fine for what I need) and it worked perfectly.
I've also seen problems where it won't find the internet after the host has been suspended / resumed. In that scenario, it turned out to be bad network drivers. I installed a dedicated Intel NIC (rather than the on-board NIC on the motherboard) - problem solved.
Basically, Hyper-V is a bit fussy.
try refreshing the hyper-v by unchecking and then checking it again,this worked for me.
Steps:
1.control panel>>programs>>Programs and features>>turn windows features on and off>>hyper-v
2.uncheck it and restart the pc.
3.again go to control panel an check hyper-v and restart the pc again.
the try to run the emulator,should work..
another possible reason is that you did not start vs2013 as admin
I have a windows 2008 Server with hyper-v enabled. I can't seem to load any network adapter into the virtual machine, it always says "Load Failed". Im really not sure what I'm doing wrong, or where to start.
Try to remove your network cards and re-connect them, I would also try to find updated drivers.
What type of card is it, It may not be supported.
Try adding a new virtual switch and select that one instead.
Here is how: http://www.eightforums.com/tutorials/19359-hyper-v-virtual-switch-manager.html
I write this just in case it can help someone, I had a similar problem, I wasn't able to see my network adapters in my windows server 2008 hyper-v machine, so the problem was the external switch couldn't be a normal one it has to be legacy external switch, so the steps I followed to resolve this were:
1- Create vm with windows server 2008 and not connected switch.
2- Goes to settings in my virtual machine an remove the not connected network adapter.
3- In settings add hardware - add legacy network adapter and connect to the external switch I had created.
And that's all. It should work like this.
