I've got a decent PC that I'd like to install xenserver on, but it's also my primary workstation. Wondering if it's possible to access guests directly from the host machine -- meaning, can I use the monitor, input devices, etc that are attached to the host, to interact with the guests.
Currently setup as a dual boot Linux and Windows machine. I need them both running simultaneously while still being able to treat the host like a workstation. Already using Virtualbox, which is great but not what I'm aiming for.
I've searched high and low for an answer to this question. Maybe I wasn't searching with the right terms. I've found a package in the Ubuntu repos that adds an entry in grub along the lines of 'Ubuntu with Xen Hypervisor', but that was on a test machine that couldn't actually run Xen.
Normally, I'd just wipe this puppy and find out for myself, but there are really good reasons why I can't just jump into it this time, so I'm turning to the community.
Thanks for any and all info!
You can use a simple text console on the host to interact with the guests
xe console vm=guest
but I don't know of a way to access a graphical interface from the host.
We are developing win-mac file sync installer which is quite similar to Dropbox. The installer is built with c++ and QT. We had a use case, where if the internet is disconnected(plugged out network cable (or) not connected to any wifi) so basically no access to web, During this case we need to make the installer into offline.
I tried few approaches like polling continuously to our web servers. If we are not able to reach then we detect as internet dis-connectivity. Due to some reasons we wanted to have clean native implementation which will look for machines network connectivity.
I even tried http://msdn.microsoft.com/en-us/library/aa965303%28VS.85%29.aspx for windows but this is failing in wifi cases even though we don't connect to wifi this example is saying "Network connected".
Can anyone suggest other alternatives. Platform specific solutions also invited.
You probably want to look at INetworkManager::GetConnectivity, and check for NLM_CONNECTIVITY_IPV4_INTERNET or NLM_CONNECTIVITY_IPV6_INTERNET in the response.
I am wondering if it is possible to limit/control ethernet upload and download speeds on specific transport layers (tcp/udp) using c++? I am trying to make a simple to use program that can control the speeds of any device that the ethernet is connected to. For example: Computer B is connected to computer A via Internet Connection Sharing, I use my program to limit computer B's download or upload speed to 120kbs (or any number i choose), with this I would also like to choose udp or tcp.
Basically, I want to create my own program similar to net limiter and other such software, but I also want to add my own features which many of which lack for my needs. These other features are easy enough, but I have no idea how to go about the actual limting process.
The way forward in the general case you ask about would be to create a virtual network adapter and all the monitored route traffic through it. Once that was done, then you can monitor streams between hosts or on specific ports.
Not an easy job... A starting point would be the Windows device driver kit.
If you were prepared to limit just one app, and could modify it, the task would be much simpler... wget and curl for example both offer limiting.

I want to run software that is protected with a dongle on a cloud instance, for example EC2. I am NOT trying to circumvent the protection, but would like to set up a tunnel between a physical machine to which the dongle is connected and the USB driver in the cloud instance.
The software is built for Windows but runs well under Linux and Mac OS using Wine so from both sides running linux would be OK.
Would this be possible without writing a USB driver?
If yes, how do I set this up?
If not, how would I go about? I am a professional C/C++ developer but have no experience with driver development.
I would start by investigating existing commercial products that do this, such as (first search hit, no special endorsement or uniqueness implied) USB over Network. They seem to solve almost exactly this problem, but for Windows clients.
On the Linux-specific side, we have USB/IP which seems to be an open source project to implement sharing of USB devices over IP networks. Again, no endorsement, I don't know how mature this project is but it seems to be the obvious starting point, perhaps you can even contribute?

Background:
I'm running a full-time job and a part-time job in the weekends, and both my employers have supplied a laptop for me to work on. Of course I also have my powerful workstation at home to work from, and sometimes when I'm at the office at my weekend job (it's in another city) I'm working from yet another workstation.
Problem:
That makes a full 4 PC's I'm maintaining (software versions, licences and settings) just to do my work, and believe me, my list of prefered software is way too big.
I want to setup a Virtual Desktop on my VMware server, so I can work from the same installation and same session no matter which PC I'm working from.
Now I don't have the time and money to go through a full test of each setup, so I'd like to hear your experiences on the subject.
Question:
Should I use a VMware virtual workstation with some remote logon software (like realVNC, teamviewer, logmein, whatever...) or should I invest in a full VDI system like Sun or VMware provide?
Edit:
I'm programming in Adobe Dreamweaver on Windows XP - but I run my servers on Debian and sometimes do quick edits in VIM too. First I intend to virtualize a WinXP with base installation, to see how it runs.
I am a consultant and tend to work in a variety of environments. I carry a Thinkpad running VMWare Server over Ubuntu64 with 4GB of RAM. I've got a 320GB secondary hard drive that I use just for VM's and have 25 or so different virtual machines that I boot up as the circumstances demand.
They're a mix of Linux servers and workstations, Vista workstations and XP Workstations. I rarely use the VMWare server console. I access every one of them via one of the remote access methods.
For Linux, I usually install FreeNX or NXServer for desktop access and just SSH for commandline. On Windows, I always use Remote Desktop (RDP), but, on XP, that only works on the "Pro" versions, not the "Home" versions. If all else fails, I install VNC and use that. VNC is at the bottom of my list because it really is a last resort. The only thing it's better than is not actually being able to use the machine.
However, NX on Linux and RDP on Windows work WAY better than VNC. Other than little things like font smoothing and fancy desktop effects, the only big glitch would be if you are doing much with video or audio or DirectX-based stuff. Things like YouTube or other video do NOT like to work with any remote desktop protocol that I know of.
As far as performance, using Linux as a host for VMWare provides really good management of system resources. The Windows-based VM's aren't able to just gobble up memory, but still get it when they need to.
I do C# development all day in a virtual Vista workstation on Visual Studio 2008 and have absolutely no problems having 3-4 different solutions all open at once along with the normal stuff alongside over RDP on another machine, connected via wireless VPN.
I can flip over to the host OS and it won't even be touching swap space at all. As far as I'm concerned, it's a great way to work.
If you want to work with the same installation, you should seriously consider the Remote Desktop Server/Client solution, bundled into every windows OS from XP. Basically, this app displays the view from your remote desktop to your local one, using highly compressed images; this works even via low-bandwidth internet connections
While the XP version can only handle one user simultaneously, the one in Windows Server 2003 (and in Windows Server 2008, I presume) can handle multiple users (up to a certain limit).
Disadvantages, and side-effects include:
virtual pc via RDC is slow
anything using the 3d acceleration will be slow (at least using XP/2003)
Personally, I would go down the route of using a virtual workstation with some remote logon software. The network performance of VMWare has always been good in my experience, and depending on the OS, there may be a decent remote logon provided.
I guess you can live with Logmein Free. [Or Pro if u want those features]
Well, you don't say what OSs are involved, so.....
For windows, I find that Remote Desktop works as well or better than anything else, although if you pay for the RealVNC version with the mirror driver, that's supposed to be as good.
For off site access for windows, www.logmein.com (the free version) works very well.
If Unixes are involved, then VNC is definitely the way to go, there are various solutions for doing this remotely. Everything from redirection servers, to just forwarding a port in your firewall to an ssh server and setting up the various tunnels.
Performance of VMWare is very good, and I can run a SQL Server slice, a web server slice and develop on my laptop simultaneously. The VM slices reside on a USB 2 portable drive and make it easy to port between my laptop and desktop.
VM Console works well for accessing each environment, and depending on the configuration you set up with NAT vs. Bridging you can UNC to shares on slice.
The nice by-product of this is that should you host machine take a nose dive you can quickly recover your development environment.
