If you are using Vagrant with KVM (with vagrant-libvirt plugin) on Fedora, you might have experienced that sometimes the KVM virtual machine becomes unresponsive. Simply put you would wait forever for trying to ssh to the machine using
vagrant ssh. It unfortunately happens to me sometimes when my laptop goes to sleep. So the simple answer is to avoid this and to always halt your Vagrant VMs when you finished working. Here is another thing to try out if you that happens and you don’t want to recreate the machine from scratch (
vagrant destroy && vagrant up).
The thing to try without any debugging is to simply reset the VM. You can achieve that using
virt-manager, just find your Vagrant VM (named by default as
default), right click on it and hit
Shut Down -> Force Reset. Afterwards go back to your project’s directory and run
vagrant halt && vagrant up if you need to sync the VM (e.g. when using NFS shares).
