If you want to move your domain/VM to another KVM host and don't have shared storage you can manually copy the data and VM config across to another host and import it. | |||
# Shutdown the virtual machine | |||
#* Preferably from the OS so it gets a graceful shutdown, alternatively stop the VM from KVM | |||
# Export the config | |||
#* EG <code> virsh dumpxl <VMname> > /tmp/VMName.xml</code> | |||
# Copy the VM disk file(s) and config XML to their new host | |||
#* Disk file(s) should go the location from which your VM's will run from | |||
# Update the config, if necessary... | |||
#* Disk file path - If the VM disks are in a different path on the new server up date the path in the XML file, look for <code>source file=</code> | |||
#* CPU type - If the physical CPU type is different on the new host, you may need to update the VM config to allow for this, update the <code>cpu mode</code> config to match the capabilities of the destination host (see https://www.berrange.com/posts/2018/06/29/cpu-model-configuration-for-qemu-kvm-on-x86-hosts/ for more info) | |||
# Import the VM | |||
#* EG <code> virsh define /path/to/VMName.xml </code> | |||
# Start the VM | |||
#* EG <code> virsh start <VMName> </code> | |||
