Killing a wedged virtual machine

While I would like to pretend that nothing ever goes wrong with Hyper-V – the fact of the matter is that sometimes things go wrong with the best systems. Hyper-V has been designed in a modular fashion so that you can easily address any problems without affecting other virtual machines. But there can be a problem in figuring out what to do when things go wrong. Imagine that on my server the “FTP Server” has stopped responding – and I cannot even turn it off: What I need to do is to kill the vmwp.exe process for the FTP Server. But... [Lire la suite]

One common used argument by the admins to not use ESXi is killing a rogue VM. Normally an SSH session would be opened to the Service Console and with “kill -9″ the VM would be killed when a “power off” did not work”. Because ESXi is COS-less this is not an option. However, it is still possible to kill these VMs by using the following procedure: login in... [Lire la suite]

Killing a frozen VM on a vSphere ESX host

Occasionally virtual machines (VMs) get stuck in a zombie state and will not respond to a power-off command using the traditional vSphere client power controls. Rebooting a host will fix this condition — but rebooting is usually not an option. Fortunately, there are a few methods for forcing the VM to shut down without rebooting the host. I previously documented these methods with VMware Infrastructure 3 (VI3) and wanted to make sure they all worked with vSphere. The methods below are listed in order of usage preference starting...
