Instance snapshots sometimes fail. This leaves the instance in
the suspended state. To work around this issue, we recommend the users
power off their VM before taking a snapshot.
Child instances launched using the snapshot of an existing parent
instance do not have a security group predefined.
Please select the appropriate security group for
child instances before launching them.
Resizing inside a flavor family (within standard.*) is
possible except for IO flavors. Resizing between flavor
families mostly does not work because of the different storage
backends. If you use a volume for the root disk, some resizes
between flavor families do work. If you use a image for the root disk,
it is possibly dangerous. Always test resizes with an expendable VM you
first. If your virtual machines end up in an "error"
state, please contact us.
Network: It is possible to add the same floating IP to multiple
instances using the API. There is no warning or error. The last
API call is the one which takes effect.
Volumes: There is no guarantee that device names will get the same
name after a rebuild or reboot. If you want to be sure that the
correct device gets mounted to the same path every time it is a good
idea to use UUIDs instead of paths.
EC2 tools (euca2ools)
EC2 is presently not supported. EC2 credentials can, however, be
used with the object storage.
