virtualization

问题 I am using Genymotion to create a virtual device but it won't start. I am getting this error: AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED). Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed} I don't have any option to enable/disable the virtualization on BIOS. I have tried to disable VT-x/AMD-V from the UI bit it would not unless I switch to Linux 32bit and 1 CPU in which case it won't boot asking for

问题 I want to be able to do so from both Windows and from Linux. I know that there are ways by getting sysinfo and using thumb rules related to hardware identifiers. I want to know if there is a more fundamental method, like looking at a memory address / issuing an interrupt etc. BTW I am trying to do this on Intel hardware and the virtualization software I use are Vmware Workstation and Windows HyperV. 回答1: Here is one more useful command: $ lscpu | grep -E 'Hypervisor vendor|Virtualization type

问题 I am attempting to get notified when an element is scrolled into view , As i understand it , ScrollViewer calls BringIntoView on it's child elements and then the child elements raise a RequestBringIntoView event which the ScrollViewer later catches and handles. This is done by Registering a Class handler for this Event and catching it as it bubbles up EventManager.RegisterClassHandler(typeof(ScrollViewer), RequestBringIntoViewEvent, new RequestBringIntoViewEventHandler(OnRequestBringIntoView)

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have been trying to download and run Back track Linux 5 r3 on my windows 8.1 (AMD Quad-Core processor, 64bit Intel.) using Virtual Box. It kept giving me the error "This Kernel requires an x86-64 bit cpu but only detected an i686 cpu so I downgraded to 4.2 Virtual Box. That solved the problem but now I keep

问题 I am developing software that is designed to run on a LAN. When multiple instances of the software are run on the network, they interfere with each other. I want multiple team members to be able to test the program simultaneously. How would I do so (without altering the program). My first thought would be to create a bunch of virtual machines running on a local box, with those machines networked together. The important thing is that I cannot generate network traffic outside of my real machine

问题 I've got a ListBox that is used to show items of multiple types (all derived from the same base type) that are bound to the ItemsSource through an ObservableCollection<T> . The performance of said ListBox is terrible. It appears that virtualization is disabled. According to: http://msdn.microsoft.com/en-us/library/cc716879(v=vs.110).aspx it seems that adding items of multiple types to the ItemsControl may be the problem. Here's my ListBox's style: <Style x:Key="{x:Type ListBox}" TargetType="

问题 I'm developing a virtual device from the user space (using umview http://wiki.virtualsquare.org/wiki/index.php/UMview) so, i need to register my device to the system's sound cards list (I've never used alsa in a kernel module so I think that I need to call the snd_card_register() function) but I can't find a way to do that from the userspace... maybe I can write a syscall to do that? 回答1: I think you should stop bothering about overriding any particular file (i.e. stop using umview, it's not

问题 A question on secuity. I want to allow non-root users to deploy containers on say a cluster, I'd be concerned if they could mount host directories and then escalate to root privileges inside the container. I gather from the articles below that the feature for mapping a container-root-user to a host-non-root-user is still in the ether? The article itself seems to be relatively old, I'm curious to know how developed these features are. "Recent improvements in Linux namespaces will soon allow to

问题 Have been trying to launch the Visual Studio Emulator for Android for quite some time with the continued end result of an error code from the log of either [Critical] XDE Exit Code: 16 , [Critical] XDE Exit Code: 3 or an infinite "Preparing Virtual Machine" status. I've tried numerous troubleshooting guides and different device profiles but haven't had any success, nor in reproducing what has worked for others. Running Windows 8.1 Pro 64-bit Things I have tried: Both Repairing and

问题 Why would you connect two docker containers via network namespace, and not just through one network? As far as I know the only difference is that you can call the other container using localhost. I don't see any use case where this would be necessary. Does anyone have experience with this? 回答1: One reason I can think of is for using a tool or command that is not available in your container. This example below comes directly from the docker run docs: NETWORK: CONTAINER Example running a Redis
