Network adapter Configuration error in Hyper-V 2012

-

we have server 2012 failover cluster 4 nodes in cluster.  migrated server 2008 r2 sp1 using cluster migration wizard last week.

when vm in "stopped" state , "quick migration" node in cluster, network adapter loses connection virtual switch , "configuration error".

when vm powered on, live migration , quick migration work fine.

this never problem before in server 2008 r2 sp1 , there refresh vm configuration option resolved of these issues doesn't exist in 2012.

is bug or there missing?

when upgraded server 2008r2 2012 installed clean, virtual hard disks on different disk

i created new virtual machines existing vhds , in minutes, virtual machines take longer boot up

this way no problems hyper-v upgrade can surface other approaches
