+# Error Control Vagrant Kubernetes
+While using `vagrant / vagrantfile` you can encounter of some errors, try to add few errors which faced during development of `kubernetes vagrant` file with solutions which worked whenever faced issues.
+
+### SSH connection get timeout or say ssh connection got reset, something like below error
+
+```bash
+SSH connection was reset! This usually happens when the machine is
+taking too long to reboot. First, try reloading your machine with
+`vagrant reload`, since a simple restart sometimes fixes things.
+If that doesn't work, destroy your machine and recreate it with
+a `vagrant destroy` followed by a `vagrant up`. If that doesn't work,
+contact support.
+```
+
+> Then can try to add below config to your vagrantfile
+```bash
+    config.vm.boot_timeout = 600
+```
+
+> if still not solved then best can try
+```bash
+$ rm -rf .vagrant
+```
+
+### While creating VM, vagrant failed to rename vm because of unclear vms
+```bash
+The name of your virtual machine couldn't be set because VirtualBox
+is reporting another VM with that name already exists. Most of the
+time, this is because of an error with VirtualBox not cleaning up
+properly. To fix this, verify that no VMs with that name do exist
+(by opening the VirtualBox GUI). If they don't, then look at the
+folder in the error message from VirtualBox below and remove it
+if there isn't any information you need in there.
+
+VirtualBox error:
+
+VBoxManage: error: Could not rename the directory '/Users/XXXXXXX/VirtualBox VMs/ubuntu-18.04-amd64_1619926105557_22107' to '/Users/XXXXXXX/VirtualBox VMs/load-balancer' to save the settings file (VERR_ALREADY_EXISTS)
+VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component SessionMachine, interface IMachine, callee nsISupports
+VBoxManage: error: Context: "SaveSettings()" at line 3249 of file VBoxManageModifyVM.cpp
+```
+
+> Simple can run command with path from error
+```bash
+$ rm -rf /Users/XXXXXXX/VirtualBox VMs/load-balancer
+```
+
+> Better to comment below line from your vagrantfile
+```bash
+    config.ssh.keep_alive = true
+```
