OpenStack Compute (Nova). 8. image0 (1). The way I understand it, naming has more to do with how the hypervisor sees the device than it does with how the OS sees the device. Console How does the mapping between list of ec2 block device mappings and windows drives happen? For eg, if i specify -b "/dev/sdb=snap-XXXXXXX" -b "/dev/sdc=ephemeral0" while launching a windows instance, it maps D:\ to the EBS volume snapshot and E:\ to ephemeral storage.

When an Ubuntu AMI starts, it will look at the root block device. Thus just fixing the block-device-mappings will not lead to successful execution of the command. snapshot-id - The ID of the snapshot used for the Amazon EBS A block device mapping defines the block devices (instance store volumes and EBS volumes) to attach to an instance. My understanding was that boot_volume was for giving the new volume (which is based on the image defined by 'image'), a label. You can use block device mappings to specify additional EBS Dec 31, 2022 · Attributes are also derived from the block device mapping for the AMI from which the instance was launched, ignoring any additional block devices that were added after launch.

It forms the foundation of the logical volume manager (LVM) , software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots . Backward compatibility issues are mostly mitigated by adding a completely new element to the servers object (block_device_mapping_v2 instead of block_device_mapping) in the POST request, and currently (API v2) Nova will handle both syntaxes (they cannot be mixed though). When I specify the mappings in the reverse order, it does the same. Required: No. Nova has a concept of block devices that can be exposed to cloud instances. This is almost always what you want to happen. For this reason, If you also want the block device mappings (in linux, the local device name of the EBS volume), you can also use EC2Connection. Modified 6 years, 7 months ago. When these prerequisites are met the command will start by locking the instance to ensure no user requests will be accepted and potentially race the refresh of the connection_info.
