Description Eduardo Habkost 2010-12-01 12:26:22 UTC
Cloning for the second issue mentioned on the report (quiting the dest VM).

+++ This bug was initially created as a clone of Bug #513765 +++

[...]
   Another phenomenon is : If quit dst vm. in src vm. QEMU cmd 'info migrate ' show migration still running. the value of _transferred ram_ and _total ram_ stuck. while the value of _remaining ram_ increase . e.g. ( in this testing, we just used 128G RAM )

Referring to comment#0
Another phenomenon is : If quit dst vm. in src vm. QEMU cmd 'info migrate '
show migration still running. the value of _transferred ram_ and _total ram_
stuck. while the value of _remaining ram_ increase . e.g. ( in this testing, we
just used 128G RAM )

re-test on kvm-83-217.el5

this issue still exists.the value of _transferred ram_ and _total ram_
stuck._remaining ram_ increase a little ,then stuck.

Expected Results:
'(qemu)info migration' should show migration failed.

Based on above ,re-assign this issue.

eventually, state of migration will shown as failed.
it needs to detect that the other side have died.  This is not a regression, is something that has always been there.

opening other bugzilla for this is ok.

Comment 1 RHEL Program Management 2011-01-11 20:10:38 UTC
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.

Comment 2 RHEL Program Management 2011-01-11 22:57:09 UTC
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.

Comment 3 Dor Laor 2011-01-16 08:33:59 UTC
Agree that we need to handle it but it is too low priority.
Closing as won't fix.
