Types

type DomainState

type DomainState int

DomainState represents a state of a domain

const (
	// DOMAIN_NOSTATE means "no state", i.e. that the domain state is undefined
	DOMAIN_NOSTATE DomainState = iota
	// DOMAIN_RUNNING means that the domain is running
	DOMAIN_RUNNING
	// DOMAIN_BLOCKED means that the domain is blocked on resource
	DOMAIN_BLOCKED
	// DOMAIN_PAUSED means that the domain is paused by user
	DOMAIN_PAUSED
	// DOMAIN_SHUTDOWN means that the domain is being shut down
	DOMAIN_SHUTDOWN
	// DOMAIN_CRASHED means that the domain is crashed
	DOMAIN_CRASHED
	// DOMAIN_PMSUSPENDED means that the domain is suspended
	DOMAIN_PMSUSPENDED
	// DOMAIN_SHUTOFF means that the domain is shut off
	DOMAIN_SHUTOFF
)

type VirtDomain

type VirtDomain interface {
	// Create boots the domain
	Create() error
	// Destroy destroys the domain
	Destroy() error
	// Undefine removes the domain so it will no longer be possible
	// to locate it using LookupByName() or LookupByUUIDString()
	Undefine() error
	// Shutdown shuts down the domain
	Shutdown() error
	// State obtains the current state of the domain
	State() (DomainState, error)
	// UUIDString returns UUID string for this domain
	UUIDString() (string, error)
	// Name returns the name of this domain
	Name() (string, error)
	// Xml retrieves xml definition of the domain
	Xml() (*libvirtxml.Domain, error)
}

VirtDomain represents a domain which corresponds to a VM

type VirtDomainConnection

type VirtDomainConnection interface {
	// Define creates and returns a new domain based on the specified definition
	DefineDomain(def *libvirtxml.Domain) (VirtDomain, error)
	// ListAll lists all the domains available on the system
	ListDomains() ([]VirtDomain, 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) (VirtDomain, 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) (VirtDomain, error)
	// DefineSecret defines a Secret with the specified value
	DefineSecret(def *libvirtxml.Secret) (VirtSecret, 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) (VirtSecret, 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) (VirtSecret, error)
}

VirtDomainConnection provides operations on domains that correspond to VMs

type VirtSecret

type VirtSecret interface {
	// SetValue sets the value of the secret
	SetValue(value []byte) error
	// Remove removes the secret
	Remove() error
}

Secret represents a secret that's used by the domain

type VirtStorageConnection

type VirtStorageConnection interface {
	// CreateStoragePool creates a storage pool based on the specified definition
	CreateStoragePool(def *libvirtxml.StoragePool) (VirtStoragePool, 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) (VirtStoragePool, error)
}

VirtStorageConnection provides operations on the storage pools and storage volumes

type VirtStoragePool

type VirtStoragePool interface {
	// CreateStorageVol creates a new storage volume based on the specified definition
	CreateStorageVol(def *libvirtxml.StorageVolume) (VirtStorageVolume, error)
	// ListAllVolumes lists all storage volumes available in the pool
	ListAllVolumes() ([]VirtStorageVolume, 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) (VirtStorageVolume, error)
	// RemoveVolumeByName removes the storage volume with the
	// specified name
	RemoveVolumeByName(name string) error
}

VirtStoragePool represents a pool of volumes

type VirtStorageVolume

type VirtStorageVolume interface {
	// Name returns the name of this storage volume
	Name() string
	// Size returns the size of this storage volume
	Size() (uint64, error)
	// Size returns the path to the file representing this storage volume
	Path() (string, error)
	// Remove removes this storage volume
	Remove() error
	// Format formats the volume as ext4 filesystem
	Format() error
}
