Currently, the virVcpuInfo returned by virDomainGetVcpus() will always report a state of VIR_VCPU_RUNNING for each defined domain vcpu even if the vcpu is currently in the halted state. As the monitor interface is in fact reporting the accurate state, it is rather easy to transport this information with the existing API. This is done by - adding a new state of VIR_VCPU_HALTED - adding a monitor function to pass back the halted state for the vcpus - adding a new field to the private domain vcpu object reflecting the halted state for the vcpu - modifying the driver code to report the vcpu state based on the halted indicator - extending virsh vcpuinfo to also display the halted state The vcpu state is however not recorded in the internal XML format, since the state can change asynchronously (without notification).
