glance镜像元数据

1、glance上传vmdk镜像
glance p_w_picpath-update 
    --property hw_disk_bus&＃61;‘ide’             
    --property vmware_disktype&＃61;"sparse"  
    --property vmware_adaptertype&＃61;"ide" 
    --property hypervisor_type&＃61;“vmware" 
    --property vmware_ostype&＃61;"windows7Server64Guest"  # 这是windows2008R2所对应的ostype
    p_w_picpath_id
    
head -n 21 disk_p_w_picpath   # 可以看到p_w_picpath的metadata
2、设置元数据
# 针对windows镜像&＃xff0c;不设置这个的话&＃xff0c;windows虚拟机时区是utc
glance p_w_picpath-update --property os_type&＃61;&＃39;windows&＃39; 
    def _set_clock(self, guest, os_type, p_w_picpath_meta, virt_type):
        # NOTE(mikal): Microsoft Windows expects the clock to be in
        # "localtime". If the clock is set to UTC, then you can use a
        # registry key to let windows know, but Microsoft says this is
        # buggy in http://support.microsoft.com/kb/2687252
        clk &＃61; vconfig.LibvirtConfigGuestClock()
        if os_type &＃61;&＃61; &＃39;windows&＃39;:
            LOG.info(_LI(&＃39;Configuring timezone for windows instance to &＃39;
                         &＃39;localtime&＃39;))
            clk.offset &＃61; &＃39;localtime&＃39;
        else:
            clk.offset &＃61; &＃39;utc&＃39;
        guest.set_clock(clk)
        if virt_type &＃61;&＃61; "kvm":
            self._set_kvm_timers(clk, os_type, p_w_picpath_meta)
            
这段是设置虚拟机时区的代码&＃xff0c; os_type是根据nova库instances里面的记录来的&＃xff0c; 而instances表里的记录是根据这里来的
 def _inherit_properties_from_p_w_picpath(self, p_w_picpath, auto_disk_config):
        p_w_picpath_properties &＃61; p_w_picpath.get(&＃39;properties&＃39;, {})
        auto_disk_config_img &＃61; \
                utils.get_auto_disk_config_from_p_w_picpath_props(p_w_picpath_properties)
        self._ensure_auto_disk_config_is_valid(auto_disk_config_img,
                                               auto_disk_config,
                                               p_w_picpath.get("id"))
        if auto_disk_config is None:
            auto_disk_config &＃61; strutils.bool_from_string(auto_disk_config_img)
        return {
            &＃39;os_type&＃39;: p_w_picpath_properties.get(&＃39;os_type&＃39;),            # 镜像元数据
            &＃39;architecture&＃39;: p_w_picpath_properties.get(&＃39;architecture&＃39;),
            &＃39;vm_mode&＃39;: p_w_picpath_properties.get(&＃39;vm_mode&＃39;),
            &＃39;auto_disk_config&＃39;: auto_disk_config
        }
