Description Oliver 2020-01-19 18:03:46 UTC
Using on source and target: 

- libvirt 6.0.0

Running:


# virsh migrate --copy-storage-inc --verbose --persistent --live kvm1793 qemu+ssh://target-node/system

will start successfully, and then during the migration, here in my case after 57%

_might_ give:

Running a second migration with the same command succeeded.

Any idea whats causing this or at least the meaning of this ?

The physical KVM hostmachines are identical in terms of CPU model.

Thank you !

Hi,
I'm seeing the same warnings about vmx-exit-load-perf-global-ctrl & vmx-entry-load-perf-global-ctrl but I doubt they are related to your migration issue.
They are just emitted when qemu starts on the target but way before migration starts and you said you got to 57%.

I've seen many those warnings when qemu/libvirt is newer than the kernel, since qemu tries to set sub-features but the kernel doesn't allow that yet.

To avoid people trail a red herring and actually look into your migration issue I'd recommend disabling vmx for the guest which will make the warning disappear.
Retrying the same again then will probably look the same (in case it was well-reproducible at all) minus these warnings.

This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '31'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 31 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 3 Ben Cotton 2020-11-24 17:37:10 UTC
Fedora 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
