Kubevirt::V1DeveloperConfiguration

Properties

Name Type Description Notes
cluster_profiler Boolean Enable the ability to pprof profile KubeVirt control plane [optional]
cpu_allocation_ratio Integer For each requested virtual CPU, CPUAllocationRatio defines how much physical CPU to request per VMI from the hosting node. The value is in fraction of a CPU thread (or core on non-hyperthreaded nodes). For example, a value of 1 means 1 physical CPU thread per VMI CPU thread. A value of 100 would be 1% of a physical thread allocated for each requested VMI thread. This option has no effect on VMIs that request dedicated CPUs. More information at: https://kubevirt.io/user-guide/operations/node_overcommit/#node-cpu-allocation-ratio Defaults to 10 [optional]
disabled_feature_gates Array<String> DisabledFeatureGates specifies a list of experimental feature gates to disable. A feature gate must not appear in both FeatureGates and DisabledFeatureGates. [optional]
disk_verification V1DiskVerification [optional]
feature_gates Array<String> FeatureGates specifies a list of experimental feature gates to enable. Defaults to none. A feature gate must not appear in both FeatureGates and DisabledFeatureGates. [optional]
log_verbosity V1LogVerbosity [optional]
memory_overcommit Integer MemoryOvercommit is the percentage of memory we want to give VMIs compared to the amount given to its parent pod (virt-launcher). For example, a value of 102 means the VMI will &quot;see&quot; 2% more memory than its parent pod. Values under 100 are effectively &quot;undercommits&quot;. Overcommits can lead to memory exhaustion, which in turn can lead to crashes. Use carefully. Defaults to 100 [optional]
minimum_cluster_tsc_frequency Integer Allow overriding the automatically determined minimum TSC frequency of the cluster and fixate the minimum to this frequency. [optional]
minimum_reserve_pvc_bytes Integer MinimumReservePVCBytes is the amount of space, in bytes, to leave unused on disks. Defaults to 131072 (128KiB) [optional]
node_selectors Hash<String, String> NodeSelectors allows restricting VMI creation to nodes that match a set of labels. Defaults to none [optional]
pvc_tolerate_less_space_up_to_percent Integer LessPVCSpaceToleration determines how much smaller, in percentage, disk PVCs are allowed to be compared to the requested size (to account for various overheads). Defaults to 10 [optional]
use_emulation Boolean UseEmulation can be set to true to allow fallback to software emulation in case hardware-assisted emulation is not available. Defaults to false [optional]
