Re: [libvirt] [test-API][PATCH 1/2] Add support for spice graphics type in xml test module

* utils/Python/xmlgenerator.py: This extends graphics element for spice XML composing, and support sub-elements settings for audio, images, streaming and so on: <graphics type='spice' autoport='yes'> <image compression='auto_glz'/> <jpeg compression='auto'/> <zlib compression='auto'/> <playback compression='on'/> <streaming mode='filter'/> <clipboard copypaste='no'/> </graphics> * utils/Python/xmlbuilder.py: Add 2 methods add_graphics() and build_graphics() to XmlBuilder class. --- utils/Python/xmlbuilder.py | 36 +++++++++++++++++++++++- utils/Python/xmlgenerator.py | 62 +++++++++++++++++++++++++++++++++++++---- 2 files changed, 91 insertions(+), 7 deletions(-) diff --git a/utils/Python/xmlbuilder.py b/utils/Python/xmlbuilder.py index 5a0f8c8..739eccb 100644 --- a/utils/Python/xmlbuilder.py +++ b/utils/Python/xmlbuilder.py @@ -64,6 +64,13 @@ class XmlBuilder: hostdev_node, domain.getElementsByTagName("console")[0]) return hostdev + def add_graphics(self, params, domain): + graphics = xmlgenerator.graphics_xml(params) + graphics_node = domain.importNode(graphics.childNodes[0], True) + domain.getElementsByTagName("devices")[0].insertBefore( + graphics_node, domain.getElementsByTagName("console")[0]) + return graphics + def build_domain_install(self, params): domain = xmlgenerator.domain_xml(params, True) self.add_disk(params, domain) @@ -151,6 +158,12 @@ class XmlBuilder: self.write_toxml(hostdev) return hostdev.toxml() + def build_graphics(self, params): + graphics = xmlgenerator.graphics_xml(params) + if __DEBUG__: + self.write_toxml(graphics) + return graphics.toxml() + def build_pool(self, params): pool = xmlgenerator.pool_xml(params) if __DEBUG__: @@ -242,6 +255,20 @@ if __name__ == "__main__": interfacexml = xmlobj.build_interface(params) + #-------------------------- + # get graphics xml string + #-------------------------- + print '=' * 30, 'graphics xml', '=' * 30 + params['graphtype'] = 'spice' + params['image'] = 'auto_glz' + params['jpeg'] = 'auto' + params['zlib'] = 'auto' + params['playback'] = 'on' + params['streaming'] = 'filter' + params['clipboard'] = 'no' + + graphicsxml = xmlobj.build_graphics(params) + #--------------------- # get pool xml string #--------------------- @@ -297,6 +324,13 @@ if __name__ == "__main__": params['memory'] = '1048576' params['vcpu'] = '2' params['inputbus'] = 'usb' + params['graphtype'] = 'spice' + params['image'] = 'auto_glz' + params['jpeg'] = 'auto' + params['zlib'] = 'auto' + params['playback'] = 'on' + params['streaming'] = 'filter' + params['clipboard'] = 'no' params['sound'] = 'ac97' params['bootcd'] = '/iso/rhel5.iso' @@ -367,7 +401,7 @@ if __name__ == "__main__": #---------------------------------------- # get domain snapshot xml string #---------------------------------------- -
