can not start one vm from save states

-

after change server processor, 1 of vm can not restore, event id 24004 , 12050, hyper-v server server 2012r2, latest update installed.

the virtual machine 'vmname 'is using processor-specific features not supported on physical computer 'hostname'. allow migration of virtual machine physical computers different processors, modify virtual machine settings limit processor features used virtual machine. (virtual machine id 0ddaa6b3-b278-4a2b-90d1-f422aa1a2955)

please help

hi spacetime_l,

processor compatibility mode not enable migrations between amd- , intel-based hosts, , if change cpu has different features fail occur, can refer following scenario.

host processor features

host b processor features

vm migration

results

same host b

(features: x, y, z)

same host a

(features: x, y, z)

host host b,

host b host a

succeeds
  succeeds

superset of host b

(features: x, y,z)

subset of host a

(features: x, y)

host host b
  host b host a

fails
  succeeds

subset of host b

(features: x, y)

superset of host a

(features: x, y,z)

host host b
  host b host a

succeeds
  fails

different set of host b*

(features: x, y)

different  set of   host a*

(features: y, z)

host host b
  host b host a

fails
  fails
