spice client should still connect to the VM for user's operation during live migration in progress.
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
This request was erroneously denied for the current release of
Red Hat Enterprise Linux. The error has been fixed and this
request has been re-proposed for the current release.
Spice server does this intentionally, seems to be needed for the spice client migration (i.e. have the spice client switch over to the new host after migration automatically). Changing this looks non-trivial and has a pretty high risk of introducing regressions.
