If you want to verify if libvirt's XML configration is valid, you may
use 'virt-xml-validate' tool to do this:
virt-xml-validate XML-FILE [SCHEMA-NAME] - validate libvirt XML files
against a schema
Thanks for telling me this. :)
Here, I don't want to verify if the xml is valid. I just want to check
if the xml configuration is the same as I thought.
But this tool is very useful, and I will try to reuse it in the future.
If you want to generate libvirt's XML configration, we have ever done
this in internal auto project, the basic idea is to create a XML
construction function for each XML element block such as '<devices> ....
</devices>', '<emulator> ... </emulator>', '<interface xxxxx> ...
</interface>', '<disk xxxxx> ... </disk>', etc. it's very flexible and
easy to reuse, you may use different XML construction function to
generate different libvirt's XML configuration, and also call them to
generate a guest XML configuration.
Thanks for this. I believe this will be very useful in attach-device
command tests.
Thanks. :)
def emulator_xml(xxxx):
# check emulator based on currently hypervisor then construct <emulator>
... </emulator>
def iface_xml(xxxx):
# to construct <interface> ... </interface>
def disk_xml(xxxx):
# .....
def devices_xml(xxxx):
......
emu_xml = emulator_xml(xxxx)
iface_xml = iface_xml(xxxx)
disk_xml = disk_xml(xxxx)
# if you want attach 2 disk then you may call disk_xml() 2 times with
different parameters.
# of course, you may use virsh attach-disk or attach-device to do this
later.
......
def guest_xml(xxxx):
......
devices_xml = devices_xml(xxxx)
......

Thanks again for all the ideas guys! Please keep sharing like this,
it's really great. I don't pretend to have all the answers, and I
really like how you're thinking ahead. Libvirt autotest is as much
yours as it is mine. Let's keep working together to get these core
modules structured how you think it will help us write tests easier!
