Objective If your KVM server has become unresponsive, you still have the possibility to access it from your Control Panel via KVM. The quickest way to diagnose the problem is to check the boot log of the server. However, the

Requirements The virtual machine must have the pty configured. From the KVM server edit the domain and make sure there is this section: From KVM Server sudo virsh edit virtual-machine <serial type=’pty’> <source path=’/dev/pts/0’/> <target type=’isa-serial’ port=’0′> <model name=’isa-serial’/> </target>

There are various ways to start virtual machines at at boot time. This means you don’t have to type virsh start vmName command. This can be done by marking a vm as autostart. To configure a domain to be automatically

Sometimes I need to extend or add disk space to my running VM (guest) to satisfy growing software requirements. KVM uses QEMU which supports several image types, among them raw, cow, qcow, qcow2, vmdk, vdi among others available. The “native”
