问题 I recently setup an Ubuntu 12.04 LTS server running nginx, and I could connect to it via its IP address. However, after restarting my computer I can no longer connect to the server in any browser but I can connect via SSH through puTTy. No clue what's going on and ifconfig shows that the IP address has not changed and I changed no settings on the server. How can I fix this? This picture shows the chrome window response when I try to access the server, the ifconfig from the server (top right),

问题 I would like to have a VM to look at how applications appear and to develop OS-specific applications, however, I want to keep all my code on my Windows machine so if I decide to nuke a VM or anything like that, it's all still there. If it matters, I'm using VirtualBox. 回答1: This is usually handled with network shares.

问题 I was using a guide in order to create a basic Jira plugin as sort of a experimental/hands-on way to get comfortable and familiar with the Jira SDK and with creating plugins regarding Listeners. I am running Ubuntu on a VM, and I followed all the steps included in the guide. My VM started to freeze, and I thought it was maybe Jira at first but now I know there is something wrong with the VM itself. I get this error: An error has occurred during virtual machine execution! The error details are

问题 I am using Oracle Virtual Box version 4.2.16 r86992. Everything was fine until yesterday shutdown.

D:\tinderbox\win-4.2\src\VBox\Main\src-server\MachineImpl.cpp[725] (long __cdecl Machine::registeredInit(void)). It's good to restore this to working, It would save lot of time and restore configuration settings

问题 For example I have an app which run vagrant machines dynamically and expect some info from them will be sent through http to specific host machine port. So, my app listening specified port (http server) and I can't forward that port: C:\node-vagrant-test-task>vagrant reload ==> default: Clearing any previously set forwarded ports... Vagrant cannot forward the specified ports on this VM, since they would collide with some other application that is already listening on these ports. The

问题 if we have 50 cloudlets/tasks and 1 virtual machine (vm) how can we make vm to run for specific time in order to apply RR method and cloudelts are run in time slice or quantum 回答1: In fact, CloudletSchedulers in CloudSim don't implement the concept of time slice/quantum. If you need to assess Cloudlets' preemption process, you can check CloudSim Plus, it's a full-featured, state-of-the-art, completely re-engineered and actively maintained CloudSim fork. It provides an implementation of the
