kvm === Introduction ------------ This software release is used to deploy KVM instances, NBD instances and Frontend instances of KVM. For extensive parameters definition, please look at parameter-input-schema.json. Examples -------- The following examples list how to request different possible instances of KVM Software Release from slap console or command line. KVM instance (1GB of RAM, 10GB of SSD, one core) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Note that the KVM instance will try to request a frontend slave instance in order to be accessible from IPv4. :: myawesomekvm = request( software_release=kvm, partition_reference="My awesome KVM", partition_parameter_kw={ "nbd-host":"ubuntu-1204.nbd.vifib.net", } ) See the instance-kvm-input-schema.json file for more instance parameters (cpu-count, ram-size, disk-size, etc). KVM instance (1GB of RAM, 10GB of SSD, one core) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Note that the KVM instance will try to request a frontend slave instance in order to be accessible from IPv4. :: myawesomekvm = request( software_release=kvm, partition_reference="My awesome KVM", partition_parameter_kw={ "nbd-host":"ubuntu-1204.nbd.vifib.net", } ) See the instance-kvm-input-schema.json file for more instance parameters (cpu-count, ram-size, disk-size, etc). Resilient KVM instance ~~~~~~~~~~~~~~~~~~~~~ Like KVM instance, but backed-up (with history) in two places. :: kvm = 'http://git.erp5.org/gitweb/slapos.git/blob_plain/refs/tags/slapos-0.188:/software/kvm/software.cfg' myresilientkvm = request( software_release=kvm, partition_reference="myresilientkvm", software_type="kvm-resilient", ) Then, if you want one of the two clones to takeover, you need to login into the hosting machine, go to the partition of the clone, and invoke bin/takeover. KVM Frontend Master Instance (will host all frontend Slave Instances) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This type of instance will allow to host any frontend slave instance requested by KVM instances. Slave instances (and thus KVM instance) will be accessible at : https://mydomain.com/instancereference . :: mykvmfrontend = request( software_release=kvm, partition_reference="mykvmfrontend", partition_parameter_kw={ "domain":"mydomain.com" }, software_type="frontend", )
