[Xen-devel] Measuring migration downtime

["Arun Babu" <arunbabu.n@xxxxxxxxx>]

Hi,
 I need to get the exact downtime for doing a live migration with ms precision.
 (I am not bothered about whole migration time which is close to 1 minute.. I need to measure
 the live migration downtime during which the DomU is out of service.. the figure quoted in the xen
 documentation says it as ~60 ms..  )
 I hope someone must have tried to measure this before.

 Can you suggest me ideas to measure this?

Thank you,

Arun
