VirtualMachineIndexOrZero ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"This textual convention is an extension of the
VirtualMachineIndex convention. This extension permits
the additional value of zero. The meaning of the value
zero is object-specific and MUST therefore be defined as
part of the description of any object that uses this
syntax. Examples of the usage of zero might include
situations where a virtual machine is unknown, or when
none or all virtual machines need to be referenced."

running(1) The administrative state of the virtual
machine indicating the virtual machine
is currently online or should be brought
online.
suspended(2) The administrative state of the virtual
machine where its memory and CPU execution
state has been saved to persistent store
and will be restored at next running(1).
paused(3) The administrative state indicating the
virtual machine is resident in memory but
is no longer scheduled to execute by the
hypervisor.

is currently offline or should be
shutting down."

STATUS current
DESCRIPTION
"The operational state of a virtual machine:
unknown(1) The operational state of the virtual
machine is unknown, e.g., because the
implementation failed to obtain the state
from the hypervisor.
other(2) The operational state of the virtual
machine indicating that an operational
state is obtained from the hypervisor, but
it is not a state defined in this MIB
module.
preparing(3) The operational state of the virtual

currently executed, but it is not in the
process of preparing(3), suspending(5),
resuming(7), migrating(9), and
shuttingdown(10).
suspending(5) The operational state of the virtual
machine indicating the virtual machine is
currently in the process of suspending
to save its memory and CPU execution
state to persistent store. This is a
transient state from running(4) to
suspended(6).
suspended(6) The operational state of the virtual
machine indicating the virtual machine is
currently suspended, which means the
memory and CPU execution state of the
virtual machine are saved to persistent
store. During this state, the virtual
machine is not scheduled to execute by
the hypervisor.
resuming(7) The operational state of the virtual
machine indicating the virtual machine is
currently in the process of resuming
to restore its memory and CPU execution
state from persistent store. This is a
transient state from suspended(6) to
running(4).

machine indicating the virtual machine is
resident in memory but no longer
scheduled to execute by the hypervisor.

currently in the process of shutting
down. This is a transient state from
running(4) to shutdown(11).

down, and CPU execution is no longer
scheduled by the hypervisor and its
memory is not resident in the hypervisor.

specifying virtual machine 1 through 8, the second octet
specifying virtual machine 9 through 16, etc. Within
each octet, the most significant bit represents the
lowest-numbered vmIndex, and the least significant bit
represents the highest-numbered vmIndex. Thus, each
virtual machine of the host is represented by a single
bit within the value of this object. If that bit has
a value of '1', then that virtual machine is included
in the set of virtual machines; the virtual machine is
not included if its bit has a value of '0'."

been queued for this device.
This would typically be implemented by storing the high
precision system timestamp of when the request is
received from the virtual machine with the request, the
difference between this initial timestamp and the time
at which the requested operation has completed SHOULD be
converted to microseconds and accumulated.
Discontinuities in the value of this counter can occur at
re-initialization of the hypervisor and administrative
state (vmAdminState) changes of the virtual machine."
