virtualization

I'm trying to figure out this virtualization feature, I'm not sure if I'm understanding it wrong or what's going on, but I'm using the ANTS memory profiler to check the number of items in a virtualized TreeView, and it just keeps increasing. I have a TreeView with 1,001 items (1 root, 1000 sub-items), and I always get up to 1,001 TreeViewItems, 1,001 ToggleButtons and 1,001 TextBlocks. Isn't virtualization supposed to re-use the items? If so, why would I have 1,001 of each? Also, the CleanUpVirtualizedItem never fires. Let me know if I'm understanding this wrong and if you have resources on

Recently my team has spent too many hours setting up machines with previous product releases or database servers with specific patches. In some cases, we have taken a developers machine down for up three days as a result. Clearly, this

I have a database docker container that is writing its data to another data-only container. The data-only container has a volume where it stores the data of the database. Is there a "docker" way of migrating this data-only container from one machine to another? I read about docker save and docker load but these commands save and load images, not containers. I want to be able to package the docker container along with its volumes and move it to another machine. Checkout the flocker project. Very interesting solution to this problem, using ZFS to snapshot and replicate the storage volume between

I wonder if there is a way to simulate laptop in a virtual machine. Specifically, I would like to simulate the lid closing behavior. I checked virtual box and it doesn't seem to have this kind of feature. Thanks! You will have to write an application to do that. The message you are interested in broadcasting is WM_POWERBROADCAST . Take a look here if you also need to catch it. 来源： https://stackoverflow.com/questions/4486560/simulating-windows-laptop-in-virtual-machine

i want to create a virtual monitor. The way this would work is that the virtual monitor would appear in a window on my desktop. As far as Windows knows it is just another monitor. It occurs to me that it would, as a practical matter, have to be done as video card driver (i.e. rather than the video going out a wire to an LCD panel, it would go into another window on the desktop). Does what i'm describing sound, technically, possible ? (from a DDK point of view) Note: i can't use a virtual pc, because no virtual PC has resolutions high enough for my needs. Also because it's not what i asked for.

Starting with Android SDK Tools rev 17 the Android emulator supports using the hardware virtualization feature (Intel VT, VT-x, vmx and AMD-V, SVM) which should speed-up x86 based emulator images a lot: http://developer.android.com/guide/developing/devices/emulator.html#accel-vm I installed all necessary components: The newest SDK tools The Intel Hardware Accelerated Execution Manager (and installed it by executing IntelHaxm.exe ) Intel Atom x86 System Image (available as API 10 and API 15 image) Then I created a new AVD using that image, but I could not "feel" any difference regarding the
