My linux instances of virtual machines without apparent reason cease to be accessible and require their reset to login again. The machine from the management console looks normal. Does anyone could give me any idea that might be? Or how can see more details of errors VMs who are causing this problem ?, Thank you.
What you need is to check the VM logs, from the Developers Console and the kernel itself.
From Developers Console, navigate to Compute > Compute engine > VN instances > click on your VM > scroll down to View Output
On the system side, depending on your Linux flavor you will need to check the system logs. Have a look at this website for more information.

This is by no means a "give me the solution" question, but more to gain a higher understanding. Please feel free to point to references where I can learn more about this, I've tried searching and all I get are how to's for setting up and accessing network drives.
I want to be able to monitor a file on a windows machine, but the file sits on a shared drive hosted locally. If it is manipulated by another machine, is there a process I can look for that will indicate that the file may be accessed by a resource elsewhere on the network? I understand that the host machine must be available in order to access the file in the first place, but what processes are called to actually manipulate the file. Is this below the OS level? I have access to a minifilter driver that I can ask a more experienced developer on the team to help me with if need be.
I have a windows 2016 server running RDS. It is configured to run a single application when a user accesses it from a .rdp shortcut. The user just sees the application as though it is running on their local machine, not a whole remote desktop.
If from a client PC, if I launch the application and log in then I can see a new connection in the RD Gateway manager.
However if I launch the application from the same client PC multiple times I am only asked to login the first time, and whilst I see many instances of the application I only see one connection in the RD gateway manager.
I would like a new connection each time I launch the application, so that I can simulate multiple users running the app concurrently in their own sessions.
I have tried adding "prompt for credentials on client:i:1" to the .rdp shortcut and this has no effect.
Thanks you your help.
I don't think it's possible. Let me try to explain:
Whenever you launch the RDP file, you connect to a session on the RDSH. Now, if you want separate connections, that means that there should be multiple sessions (probably for the same user since the credentials don't change) which is not allowed by the RDSH by default.
Assuming you get passed multiple sessions for same user, MSTSC actually recognizes that for the given RDP file, there is already an open connection, so it will try to reuse that.
Last but not least, there is the problem of licensing - you are "working around" the system: both per-device and per-user licensing would report 1, therefore it would probably be a violation of ToS.
It would be much more useful if you could tell us what you are trying to achieve and then maybe we can help you more.
P.S.: This question has nothing to do with programming, so it probably belongs to https://superuser.com
Hi I figured out a solution to this, so I will share in case it is useful for anyone else.
Modify the hosts file to include different names for the target machine ip address:
eg:
51.xxx.159.233 test1.xxx.uk-user1
51.xxx.159.233 test1.xxx.uk-user2
51.xxx.159.233 test1.xxx.uk-user3
51.xxx.159.233 test1.xxx.uk-user4
Then in each rdp launch shortcut, reference a different alias.
eg:
Shortcut1:
full address:s:test1.xxx.uk-user4
Shortcut2:
full address:s:test1.xxx.uk-user3
Then when the RDP is launched it will ask you to log in even if you already have an active connection and server will have a new user logged into it.
Hope this helps somone in the future.
I am helping a friend out with his new startup and he is looking into the possiblity of buying a server. A big part of the business involves running scripts to test various programs. The scripts automate mouse movement and clicks and keyboard inputs, basically mimicing a human user and logging how to program responds.
I understand that using virtualization, he could have one server running multiple instances of the operating system simulatnously. Unfortunately I don't have any experience with this.
What we would need to do is as follows:
Open an instance of remote desktop instance on the server through a laptop.
Run one of the automation scripts and watch the mouse move around the screen doing its work
Close the remote desktop on my laptop but leave the script running with the mouse moving around the virtual screen doing its work
Open 10 more instances of remote desktop to do the same thing
Login to each remote desktop a week later and check the progress
Basically if I close an instance of remote desktop, is there a way to keep the automated mouse movement script running?
Is there a limit to the number of instances that can be run at once?
I'd be greatful if someone could point me to some instructions on how this would work? As you could probably guess neither of us are IT experts! Thank you
I have pressed the capture button on a VM in dev test labs. Now it looks like I have a generalized VM that looks useless to me. For example, I can not start the VM anymore. It just displays the following error message.
Failed to start virtual machine 'vmname'. Error: Operation 'start' is not allowed on VM 'vmname' since the VM is generalized.
I need to access this VM what can I do ?
** Should I have run sysprep before I hit the capture???
As I can not start another VM it give this error. Provisioning failed.
OS Provisioning for VM 'IntegrationTest' did not finish in the
allotted time. However, the VM guest agent was detected running. This
suggests the guest OS has not been properly prepared to be used as a
VM image (with CreateOption=FromImage). To resolve this issue, either
use the VHD as is with CreateOption=Attach or prepare it properly for
use as an image: * Instructions for Windows:
Don't use this button without SYSPREP.
Use regular backup.
IMHO the capture process is not as easy as AWS EC2... This error* caused us a day.
*It was my fault to hit the button where I thought it would just work. I should have tested it.
I have registered my Phone 7 app as a Share Picker Extension. It works—my app is in the list of Share options and it gets launched and I can load the chosen image. Okay, great.
But then things go wrong in my code. I would like to be able to debug the issues, but I can't seem to keep the debugger attached.
I cannot debug this in the simulator, since the Pictures app (and thus the Share Picker functionality) is not present in the simulator.
I cannot debug this on the phone because as soon as I pick my app from the Share list, the debugger detaches... right as my app is "launching" again.
Is it possible to attach the debugger to a running WP7 app? Is it possible to keep the debugger attached? Am I doing it wrong? Any suggestions, advice or guesses are welcome because I'm tearing my hair out.
When doing M+V hub integration (sorry, haven't done any pictures hub integration yet) I initially used a crude debug technique (Messagebox.Show, etc. - like Justin mentioned) to verify what was being passed to the NavigationEventArgs of OnNavigatedTo and wrapped the whole method in a try..catch block to learn what was going on. I then refactored the code when I knew what could be expected. (Remember OnNavigatedTo will be called when your app is launched normally too and so e won't be populated in the same way.)
When the app is launched from a/the hub it creates a new instance of the app and there is currently no way to connect to this for debugging while the main page is being navigated to.
Great question. I'm unsure if that's possible. As far as I know, there's no way to attach the debugger to when the WP7 O/S starts an app (which wasn't triggered by the debugger).
Photo Share picker extensibility, music+Video hub extensibility and other O/S extensibility points seem to not play nicely with the VS debugger. Normally I resort to MessageBox.Show to debug any problems with WP7 O/S integration.
1) Connect the Device
2) Turn off Zune
3) Start C:\Program Files\Microsoft SDKs\Windows Phone\v7.1\Tools\WPConnect\x86\WPConnect.exe
To properly debug your application that uses the Media Library, you'll need to use the Windows Phone Connect Tool (WPConnect.exe) as described on MSDN. Jaime has some additional tips on his blog.
Once you are connected, you should be able to debug your application. Fingers crossed anyway. If that doesn't help, I'll dig a bit further.
It's not so much about the WPConnect tool. The nature of your application means that you have to have it closed and the user should pick a photo. Only after that the data is returned to the application.
You should read about the application execution model on Windows Phone 7. Also a good explanation is available here.
Initially, I would say that you should look at tombstoning (a good explanation here) but then again, the image returned will re-start the app and won't allow you to directly attach the debugger.
Yeah, looks like this is impossible...
All the answers above seem to be missing the point: I presume you're able to debug your app in the "standalone" mode (when it's launched normally), but not when it's launched via the Share Picker Extension. Am I write? This is the wall I'm hitting... :-(
I thought the proper way would be to attach to the process once it's launched.
I tried to use Debug > Attach to Process, then select Smart Device as the Transport and Windows Phone Device as the Qualifier... But in return I get the ugly "Unable to connect to 'Windows Phone Device'. Not implemented" message.
Bummer :-(
