Folgende Punkte sind die chronilogische Abfolge einer Live Migration:
 +
*Establish connection between source and target computer
 +
*Transfer VM configuration and device information

=== Blackout-Time ===

Die Blackout-Time ist die Zeit zwischen der, der Hyper-V Host die Source-VM stoppt, den State transferiert und die Target-VM "startet". (Siehe Bild auf der rechten seite.)
 +
Die Blackout-Time einer VM entsteht bei einer Live Migration und ist im EventLog des Hyper-V Nodes unter dem Provider ''Microsoft-Windows-Hyper-V-VMMS-Admin'' ersichtlich.

''Die "Blackout-Time" und die "stun-time" bedeuten das Gleiche.''

Live Migration

Folgende Punkte sind die chronilogische Abfolge einer Live Migration:

  • Establish connection between source and target computer
  • Transfer VM configuration and device information
  • Transfer VM memory
  • Suspend source VM and transfer state
  • Resume target VM

Das Ziel ist es kein TCP/IP Timeout zu bekommen.

Blackout-Time

Die Blackout-Time ist die Zeit zwischen der, der Hyper-V Host die Source-VM stoppt, den State transferiert und die Target-VM "startet". (Siehe Bild auf der rechten seite.) Die Blackout-Time einer VM entsteht bei einer Live Migration und ist im EventLog des Hyper-V Nodes unter dem Provider Microsoft-Windows-Hyper-V-VMMS-Admin ersichtlich. Die "Blackout-Time" und die "stun-time" bedeuten das Gleiche.
