	GetRSS() (uint64, error)
	// GetCPUTime returns cpu time used by VM in nanoseconds per core
	GetCPUTime() (uint64, error)
}

Domain represents a domain which corresponds to a VM

type DomainConnection added in v1.0.0

type DomainConnection interface {
	// Define creates and returns a new domain based on the specified definition
	DefineDomain(def *libvirtxml.Domain) (Domain, error)
	// ListDomains lists all the domains available on the system
	ListDomains() ([]Domain, error)
	// LookupByName tries to locate the domain by name. In case if the
	// domain cannot be found but no other error occurred, it returns
	// ErrDomainNotFound
	LookupDomainByName(name string) (Domain, error)
	// LookupDomainByUUIDString tries to locate the domain by its UUID. In case if the
	// domain cannot be found but no other error occurred, it returns
	// ErrDomainNotFound
	LookupDomainByUUIDString(uuid string) (Domain, error)
	// DefineSecret defines a Secret with the specified value
	DefineSecret(def *libvirtxml.Secret) (Secret, error)
	// LookupSecretByUUIDString tries to locate the secret by its UUID. In case if the
	// secret cannot be found but no other error occurred, it returns
	// ErrSecretNotFound
	LookupSecretByUUIDString(uuid string) (Secret, error)
	// LookupSecretByUsageName tries to locate the secret by its Usage name. In case if the
	// secret cannot be found but no other error occurred, it returns
	// ErrSecretNotFound
	LookupSecretByUsageName(usageType string, usageName string) (Secret, error)
}

DomainConnection provides operations on domains that correspond to VMs

type DomainState

type DomainState int

DomainState represents a state of a domain

const (
	// DomainStateNoState means "no state", i.e. that the domain state is undefined
	DomainStateNoState DomainState = iota

	SetValue(value []byte) error
	// Remove removes the secret
	Remove() error
}

Secret represents a secret that's used by the domain

type StorageConnection added in v1.0.0

type StorageConnection interface {
	// CreateStoragePool creates a storage pool based on the specified definition
	CreateStoragePool(def *libvirtxml.StoragePool) (StoragePool, error)
	// LookupByName tries to locate the storage pool by its
	// UUID. In case if the domain cannot be found but no other
	// error occurred, it returns ErrStoragePoolNotFound
	LookupStoragePoolByName(name string) (StoragePool, error)
	// ListPools() retrieves the list of pools
	ListPools() ([]StoragePool, error)
	// PutFiles add files to the specified image.
	PutFiles(imagePath string, files map[string][]byte) error
}

StorageConnection provides operations on the storage pools and storage volumes

type StoragePool added in v1.0.0

type StoragePool interface {
	// CreateStorageVol creates a new storage volume based on the specified definition
	CreateStorageVol(def *libvirtxml.StorageVolume) (StorageVolume, error)
	// ListVolumes lists all the storage volumes available in the pool
	ListVolumes() ([]StorageVolume, error)
	// LookupVolumeByName tries to locate the storage volume by its
	// UUID. In case if the domain cannot be found but no other
	// error occurred, it returns ErrStorageVolumeNotFound
	LookupVolumeByName(name string) (StorageVolume, error)
	// RemoveVolumeByName removes the storage volume with the
	// specified name
	RemoveVolumeByName(name string) error
