Instance Attribute Details

#allow_auto_converge ⇒ Object

AllowAutoConverge allows the platform to compromise performance/availability of VMIs to guarantee successful VMI live migrations. Defaults to false



20
21
22
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 20

def allow_auto_converge
  @allow_auto_converge
end

#allow_post_copy ⇒ Object

AllowPostCopy enables post-copy live migrations. Such migrations allow even the busiest VMIs to successfully live-migrate. However, events like a network failure can cause a VMI crash. If set to true, migrations will still start in pre-copy, but switch to post-copy when CompletionTimeoutPerGiB triggers. Defaults to false



23
24
25
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 23

def allow_post_copy
  @allow_post_copy
end

#allow_workload_disruption ⇒ Object

AllowWorkloadDisruption indicates that the migration shouldn't be canceled after acceptableCompletionTime is exceeded. Instead, if permitted, migration will be switched to post-copy or the VMI will be paused to allow the migration to complete

#bandwidth_per_migration ⇒ Object

Quantity is a fixed-point representation of a number. It provides convenient marshaling/unmarshaling in JSON and YAML, in addition to String() and AsInt64() accessors. The serialization format is: <quantity> ::= <signedNumber><suffix> (Note that <suffix> may be empty, from the \"\" case in <decimalSI>.) <digit> ::= 0 | 1 | ... | 9 <digits> ::= <digit> | <digit><digits> <number> ::= <digits> | <digits>.<digits> | <digits>. | .<digits> <sign> ::= \"+\" | \"-\" <signedNumber> ::= <number> | <sign><number> <suffix> ::= <binarySI> | <decimalExponent> | <decimalSI> <binarySI> ::= Ki | Mi | Gi | Ti | Pi | Ei (International System of units; See: http://physics.nist.gov/cuu/Units/binary.html) <decimalSI> ::= m | \"\" | k | M | G | T | P | E (Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.) <decimalExponent> ::= \"e\" <signedNumber> | \"E\" <signedNumber> No matter which of the three exponent forms is used, no quantity may represent a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal places. Numbers larger or more precise will be capped or rounded up. (E.g.: 0.1m will rounded up to 1m.) This may be extended in the future if we require larger or smaller quantities. When a Quantity is parsed from a string, it will remember the type of suffix it had, and will use the same type again when it is serialized. Before serializing, Quantity will be put in "canonical form". This means that Exponent/suffix will be adjusted up or down (with a corresponding increase or decrease in Mantissa) such that: - No precision is lost - No fractional digits will be emitted - The exponent (or suffix) is as large as possible. The sign will be omitted unless the number is negative. Examples: - 1.5 will be serialized as "1500m" - 1.5Gi will be serialized as "1536Mi" Note that the quantity will NEVER be internally represented by a floating point number. That is the whole point of this exercise. Non-canonical values will still parse as long as they are well formed, but will be re-emitted in their canonical form. (So always use canonical form, or don't diff.) This format is intended to make it difficult to use these numbers without writing some sort of special handling code in the hopes that that will cause implementors to also use a fixed point implementation.

end

#completion_timeout_per_gi_b ⇒ Object

CompletionTimeoutPerGiB is the maximum number of seconds per GiB a migration is allowed to take. If the timeout is reached, the migration will be either paused, switched to post-copy or cancelled depending on other settings. Defaults to 150

  @completion_timeout_per_gi_b

#disable_tls ⇒ Object

When set to true, DisableTLS will disable the additional layer of live migration encryption provided by KubeVirt. This is usually a bad idea. Defaults to false

37
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 35

def disable_tls
  @disable_tls
end

#match_se_linux_level_on_migration ⇒ Object

By default, the SELinux level of target virt-launcher pods is forced to the level of the source virt-launcher. When set to true, MatchSELinuxLevelOnMigration lets the CRI auto-assign a random level to the target. That will ensure the target virt-launcher doesn't share categories with another pod on the node. However, migrations will fail when using RWX volumes that don't automatically deal with SELinux levels.

# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 38

def match_se_linux_level_on_migration

#max_downtime_ms ⇒ Object

MaxDowntimeMs specifies the maximum tolerable downtime (in milliseconds) during switchover. Defaults to 900

42
43
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 41

def max_downtime_ms
  @max_downtime_ms

#network ⇒ Object

Network is the name of the CNI network to use for live migrations. By default, migrations go through the pod network.

# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 44

def network
  @network
end

#node_drain_taint_key ⇒ Object

NodeDrainTaintKey defines the taint key that indicates a node should be drained. Note: this option relies on the deprecated node taint feature. Default: kubevirt.io/drain

# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 47

def node_drain_taint_key

#parallel_migrations_per_cluster ⇒ Object

#parallel_outbound_migrations_per_node ⇒ Object

ParallelOutboundMigrationsPerNode is the maximum number of concurrent outgoing live migrations allowed per node. Defaults to 2

54
55
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 53

def parallel_outbound_migrations_per_node
  @parallel_outbound_migrations_per_node
end

#progress_timeout ⇒ Object

ProgressTimeout is the maximum number of seconds a live migration is allowed to make no progress. Hitting this timeout means a migration transferred 0 data for that many seconds. The migration is then considered stuck and therefore cancelled. Defaults to 150



56
57
58
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 56

def progress_timeout
  @progress_timeout
end

#unsafe_migration_override ⇒ Object

UnsafeMigrationOverride allows live migrations to occur even if the compatibility check indicates the migration will be unsafe to the guest. Defaults to false



59
60
61
 
# File 'lib/kubevirt/models/v1_migration_configuration.rb', line 59

def unsafe_migration_override
  @unsafe_migration_override
end

#utility_volumes_timeout ⇒ Object

UtilityVolumesTimeout is the maximum number of seconds a migration can wait in Pending state for utility volumes to be detached. If utility volumes are still present after this timeout, the migration will be marked as Failed. Defaults to 150
