What were you trying to do that didn't work?
Do migration and then pause the migration using domjobabort, but migration hangs
Please provide the package NVR for which the bug is seen:
libvirt-10.10.0-13.el9.aarch64
qemu-kvm-9.1.0-25.el9.aarch64
How reproducible is this bug?:
10%
Steps to reproduce
- Setup migration env with nfs and tcp
- In terminal 1, run
virsh event --loop --all --timestamp
- In terminal 2, start vm and set migration speed to low, run migration command
virsh start vm1
Domain 'vm1' started
virsh migrate-setspeed vm1 8 --postcopy
virsh migrate-setspeed vm1 8
virsh migrate --live --p2p --verbose --domain vm1 --desturi qemu+tcp://10.6.6.26/system --timeout 4 --timeout-postcopy --postcopy - Monitor the event in terminal 1, when below event is printed, do domjobaort to pause the migration in terminal 3
virsh event --loop --all --timestamp
...
event 'migration-iteration' for domain 'vm1': iteration: '1' - In terminal 3, run command to pause the migration. Sometimes below error from qemu will display
virsh domjobabort vm1 --postcopy
error: internal error: unable to execute QEMU command 'migrate-pause': migrate-pause is currently only supported during postcopy-active or postcopy-recover state - At this time, the migration command in terminal 2 will hang
virsh migrate --live --p2p --verbose --domain vm1 --desturi qemu+tcp://10.6.6.26/system --timeout 4 --timeout-postcopy --postcopy
