Hi,
=20
I recently upgraded an oVirt deployment from 3.6 to 4.0 and then 4.1.9 =
(my actual
release). Since then, when migrating many hosts =
simultaneously I always experience few migrations failure like 1 on 10 =
vms. The failure can occur on any host; moreover, after a couple of =
failure the destination host fall in Error status and I have to manually =
re-activate or wait 30 min.
=20
Tipical error found on vdsm log is (from the source host):
2018-04-12 17:01:32,097+0200 ERROR (migsrc/3192dfe7) [virt.vm] =
(vmId=3D'3192dfe7-eeac-4626-8c86-e49facc9006f') migration destination =
error: Fatal error during migration (migration:287)
=20
Please find the logs of source host (v15.ovirt), destination host =
(v14.ovirt) and
engine here: =

Some of the vm affected from the migration failure are:
svn 3192dfe7-eeac-4626-8c86-e49facc9006f
wood a8e83ff0-dfed-4074-b6b6-e947b8ebb952
qnx66 5697c4a4-9e40-4dd6-aba2-c8ab9904a584
can you also include qemu log from /var/log/libvirt/qemu/<vmname>?
btw you seem to be using the legacy migration policy throttling the =
speed significantly. Please read into the migration enhancements in 4.0
