[Users] VM migrate failed Host CPU does not provide required features: hle, rtm, rdseed...

Fri Sep 7 19:10:35 MSK 2018

Dear Jehan,

collegians pointed me that cpupools works with vstorage cluster only,
and obviously you are right, it is part of commercial virtuozzo,
so it cannot help in common case.

I'm sorry for misinformation.

Thank you,
