Hi, You should to modify nova.virt.libvirt.connection._create_image. This is source code about make a local disk. 959 local_gb = inst['local_gb'] 960 if local_gb and not self._volume_in_mapping( 961 self.default_local_device, block_device_info): 962 fn = functools.partial(self._create_ephemeral, 963 fs_label='ephemeral0', 964 os_type=inst.os_type) 965 self._cache_image(fn=fn, 966 target=basepath('disk.local'), 967 fname="ephemeral_%s_%s_%s" % 968 ("0", local_gb, inst.os_type), 969 cow=*FLAGS.use_cow_images*, 970 local_size=local_gb) You can change 'cow' value to FALSE. (FLAGS.use_cow_images is TRUE by default). then _cache_image function make a disk to raw format. 2011/11/8 ljvsss <[email protected]>hi all if i create an instance flavor of m1.large(4u,8GRAM.80G disk),at floder here /var/lib/nova/instances/instance-0000006 will have two img:disk and disk.local they format is same,qcow2 or raw what i want is the "disk" (instance os disk) format is qcow2,and the disk.local's format is raw,because qcow2 is small and easy to make snapshots,raw's speed is bettter what should i do? thanks :) _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
