virtual-machine

问题 During the past years, I configured several Debian VMs for personal usage, using either VirtualBox or Vmware. However, I am not a sysadmin, nor do I operate any servers. Instead, my main usage of VMs is to install "throwaway programs" or "untrusted programs" that I do not want to pollute my host system, and I definitely need a full graphical environment within these VMs. Unfortunately, this setup has always been a painful manual process, and I always have to lookup several sites to find out

问题 Background I have been developing Drupal Sites for a little over 2 years now and I have noticed that my dev environments are not as user friendly and as simple as I have expected. The current process is we have a git repo where we store all the code, then we have a vagrant box setup as our virtual machine to run our local development in. The issue comes along with the fact of constantly having to go through loop holes of trying to get everything to work well together. Or there will be issues

问题 In https://github.com/qemu/qemu/blob/stable-4.2/cpus.c#L1290 lies a very important piece of Qemu. I guess it's the event loop for a CPU on KVM. Here is the code: static void *qemu_kvm_cpu_thread_fn(void *arg) { CPUState *cpu = arg; int r; rcu_register_thread(); qemu_mutex_lock_iothread(); qemu_thread_get_self(cpu->thread); cpu->thread_id = qemu_get_thread_id(); cpu->can_do_io = 1; current_cpu = cpu; r = kvm_init_vcpu(cpu); if (r < 0) { error_report("kvm_init_vcpu failed: %s", strerror(-r));

问题 I am running VirtualBox 5.0.24 and Vagrant 1.8.5 on Digital Ocean VPS running on Ubuntu 14.04 LTS Precise I am using the box ubuntu/precise64 Everything works fine but when i do vagrant up it hangs at the SSH auth method: Private key and the exit out giving time out. Now, i can consider increasing the execution time but it already takes a fare amount of time before giving that error. I don't know what I am doing wrong. Here is my VAGRANTFILE # -*- mode: ruby -*- # vi: set ft=ruby : Vagrant
