glance image-create
command provides a large set
of options for working with your image. For example, the
min-disk
option is useful for images that require root
disks of a certain size (for example, large Windows images). To view
these options, do:location
option is important to note. It does not
copy the entire image into the Image service, but references an original
location where the image can be found. Upon launching an instance of
that image, the Image service accesses the image from the location
specified.copy-from
option copies the image from the
location specified into the /var/lib/glance/images
directory. The same thing is done when using the STDIN redirection with
<, as shown in the example.compute_extension:flavormanage
in
/etc/nova/policy.json
on the nova-api
server).
To get the list of available flavors on your system, run:nova flavor-create
command allows authorized users
to create new flavors. Additional flavor manipulation commands can be
shown with the command: nova.conf

share: whether other tenants can or cannot see the share. By default,
the share is private. Now you can mount the created share like a remote
file system and use it for your purposes.
rw
: read and write (RW) access. This is the default
value.
ro:
read-only (RO) access.
ip
: authenticates an instance through its IP address.
A valid format is XX.XX.XX.XX orXX.XX.XX.XX/XX.
For example 0.0.0.0/0.
cert
: authenticates an instance through a TLS
certificate. Specify the TLS identity as the IDENTKEY. A valid
value is any string up to 64 characters long in the common name
(CN) of the certificate. The meaning of a string depends on its
interpretation.
user
: authenticates by a specified user or group
name. A valid value is an alphanumeric string that can contain
some special characters and is from 4 to 32 characters long.

fsfreeze
tool, which halts new access to the file system,
and create a stable image on disk that is suitable for snapshotting.
The fsfreeze
tool supports several file systems,
including ext3, ext4, and XFS. If your virtual machine instance is
