Ok, here comes the huge patch for today - a major extension of the test driver backend... As well as the interal hardcoded 'test:///default' hypervisor config you can now provide a path to an arbitrary XML file defining your HV and its domains. An example file to define a moster 128x6GHz CPU box with 128 GB of RAM and two guest domains looks like: <node> <domain file="testdomfv0.xml"/> <domain file="testdomfc4.xml"/> <cpu> <mhz>6000</mhz> <model>i986</model> <active>50</active> <nodes>4</nodes> <sockets>4</sockets> <cores>4</cores> <threads>2</threads> </cpu> <memory>137438953472</memory> </node> The individual domains 'testdomfv0.xml' and 'testdomfc4.xml' are defined using the regular libvirt XML format. The only exception is that the 'type' attribute on the top level '<domain>' tag should be 'test' instead of 'xen' So for example: $ virsh --connect test:///home/berrange/src/xen/libvirt/docs/testnode.xml virsh > nodeinfo CPU model: i986 CPU(s): 50 CPU frequency: 6000 MHz CPU socket(s): 4 Core(s) per socket: 4 Thread(s) per core: 2 NUMA cell(s): 4 Memory size: 137438953472 kB virsh > list Id Name State ---------------------------------- 0 fv0 running 1 fc4 running virsh > dominfo fc4 Id: 1 Name: fc4 UUID: ef861801-45b9-11cb-88e3-afbfe5370493 OS Type: linux State: running CPU(s): 1 CPU time: 1155740835.5s Max memory: 131072 kB Used memory: 131072 kB virsh > Next up, I've written implementations of the set memory, set max memory, set vcpus, dump xml, create linux APIs for the test driver. THe only major areas of functionality lacking in the test driver now are handling of disk and network devices when creating domains, and the VCPU pinning methods. This test backend makes testing the virt-manager application much more reliable - although we still do need some level of testing against a real Xen backend (for example domain creation).
