This means that if needed, the machine will definitely getĪllocated the reserved amount of CPU cycles.Ĭpu_quota: Specifies the maximum allowed bandwidth (unit: It can be used to enforce a limit on theĬpu_reservation: Specifies the guaranteed minimum CPU reservation in This parameter ensures that a machine never uses more than theĭefined amount of CPU time. A period with value 0 means noĬpu_limit: Specifies the upper limit for VMware machine CPU allocation Not allowed to consume more than the quota worth of runtime. Within a period, each VCPU of the domain is The number of shares using cpu_shares_share.Ĭpu_period: Specifies the enforcement interval (unit: microseconds)įor QEMU and LXC hypervisors. Twice as much CPU time as a VM configured with value 1024.Ĭpu_shares_level: On VMware, specifies the allocation level. For example, a VM configured with value 2048 gets There is no unit for the value it is a relative measure based on If this element is omitted, the service defaults to the OS providedĭefaults. Use these optional parameters to control weight shares, enforcement intervalsįor runtime quotas, and a quota for maximum allowed bandwidth:Ĭpu_shares: Specifies the proportional weighted share for the domain. property quota:write_bytes_sec = 10240000 If unspecified, the value is 1.0 by default. The receive/transmit factor of any network ports on the instance. Swap Amount of swap space (in megabytes) to use. When a VM is terminated, all data on the ephemeral disk is lost.Įphemeral disks are not included in any snapshots. If unspecified, the value is 0 by default.Įphemeral disks offer machine local disk storage linked to the lifecycle of a Ephemeral Disk GBĪmount of disk space (in gigabytes) to use for the ephemeral partition. Os_compute_api:servers:create:zero_disk_flavor policy rule. Volume-backed instancesĬan be enforced for flavors with zero root disk via the As a result, 0 should only be usedįor volume booted instances or for testing purposes. However, in this case the filter scheduler cannot select the compute The 0 size is a specialĬase which uses the native base image size as the size of the ephemeral root Whenīooting from a persistent volume it is not used. The root disk is an ephemeral disk that the base image is copied into. Root Disk GBĪmount of disk space (in gigabytes) to use for the root ( /) partition. Memory MB Amount of RAM to use (in megabytes). Not required, though some third party tools may rely on it. Historically, names were given a format XX.SIZE_NAME. Specifying ‘auto’, a UUID will be automatically generated. A flavor consists of the following parameters: Flavor ID Unique ID (integer or UUID) for the new flavor.
