About live migration of KVM guest

Solution Verified - Updated -

Issue

  • There are two questions about Live Migration.

    1) About the live migration failure message
    Live migration failed with the following message.

Cannot recv data: Host key verification failed.: Connection reset by peer

  • Could you tell us how to deal with this message?

    2) About the method of settlement of the host name
    There is the following description in "4.3. Live KVM
    migration with virsh" of "Red Hat Enterprise Linux 6
    Virtualization Administration Guide".

    Important
    An entry for the destination host, in the /etc/hosts file on the source server is required for
    migration to succeed. Enter the IP address and hostname for the destination host in this file as
    shown in the following example, substituting your destination host's IP address and hostname:
    10.0.0.20 host2.example.com

  • Can the above mention be substituted with the DNS server?
