virtualization

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 6 years ago . I'm trying to move an application to the web that contains a tree of up to 50,000 nodes. I first tried to produce this using jqxtree widget, but the DOM was far too large and they clearly don't support thousands of nodes. I'm looking for a virtualised solution and while I've seen

问题 I'm working with the wpf toolkit datagrid and have a column that is populated with toggle buttons. Using the below style I change the background color if the toggle button is selected and also on mouse over. Unfortunately if I have virtualization enable, when I make a select of a toggle button in a cell and scroll down in the grid I will find other cells that have also had their background changed. I assume this is a bug in how virtualization is reusing the cells as I scroll. Any suggestion

问题 Couldn't find an answer, so I thought I ask for myself. Using C#, how can I check if the CPU has hardware virtualization enabled? Hyper-V, for example. It's not in the Win32_Processor class, and my attempt to connect to the MSVM_ComputerSystem was met with utter failure. Keeps telling me there's an invalid namespace. Code below. ManagementObjectSearcher vm = new ManagementObjectSearcher(@"\\.\root\virtualization", "select * from MSVM_Computersystem"); ManagementObjectCollection vmCollection =

问题 I work in Ubuntu from Oracle Virtual Machine which is installed on top of Windows. I have activated the VT-x feature in the host BIOS. After this I created a new virtual machine with VT-x and EPT enabled. Now I run $ egrep '(vmx|svm)' /proc/cpuinfo from the guest to check if the vmx feature is enabled and the answer is 0, i.e. not enabled. How can I enable this feature on the guest VM? 回答1: You can't enable VT-x inside Virtualbox. There's a ticket for it that hasn't been fixed yet [Edit by

问题 I have a strange problem with virtualization enabled ListView control. I created a very small pilot app to reproduce the issue. When I type-in something for a few textboxes in the listview and then scrolling down, after a few pages the typed-in values are repeating in the untouched textboxes below. Here is the XAML of the window: <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

问题 I am running Docker Toolbox v. 1.13.1a on Windows 7 Pro Service pack 1 x64 OS. with Virtual Box Version 5.1.14 r112924 when I try to run any docker image e.g. official postgres image from Docker Hub with volumes disabled, it works fine! But when I enable the volumes it fails . I tried all official documentations The VM has shared folder as required and has full access to it also shared folder screenshot In case of my example of postgresql it crashes with following log The files belonging to

问题 Is it possible to emulate Kinect sensor (for usage with Kinect SDK), when the Kinect itself isn't plugged? First I thought Kinect Studio does exactly what I wanted, but now it seems like Kinect Studio records data streams and can "feed" them to application, but is unable to emulate connection to the sensor. So at the moment I have a couple of .xed files recorded with Kinect Studio and I can't launch any Kinect-enabled apps without getting "Kinect sensor is not plugged in" or whatever message.

问题 I first thought that Xen was a host hypervisor. But i later found that it was a bare metal hypervisor. How does Xen qualify as a Bare metal hypervisor ? 回答1: Because Xen can be booted to directly from BIOS, without any other operating system in between Xen and the hardware. VMware ESXi is similar (differentiating itself from VMware workstation which requires a host OS). Xen's dom0 privleged guest can be installed on the system before Xen is enabled, thus confusing matters about whether it is

问题 I don't think the question needs any explanation. I'm writing a software that can boot virtual machines to simulate a network. I would like to disable this feature if the software is already running on a virtual machine. I already read this post: How to detect if my application is running in a virtual machine? But I need to do it on Linux and that post covers only Windows. I'm tagging it as a Perl question as I've to do it in Perl, but probably there are some file in proc or somewhere else to

问题 Heres the problem. I use around three different machines for development. My partner is using two. We have to go through the same freaking set up procedure on all five machines to get to work. Working with a php project here, so: Install and configure, PDT, a php debugger, and some version of XAMPP. Then possible install an svn client, and any other tools. Again, to each of the five machines. What if, instead, we did all of this once, in a virtual machine that is set up with the same stack,
