[ovirt-users] Re: guests crashing during live migration(NUMA config issue)

Hello, I ran into a similar error. After updating the management to oVirt Manager: CentOS 7.5 ovirt: 4.2.3.8-1.el7 I tried to put the 1st host into maintenance mode to do the update. Since ~ 4h, the server tries to migrate all of the VMs without success. On the 'reception' host /var/log/libvirt/qemu shows following error: 2018-06-07T12:57:54.420311Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2018-06-07T12:57:54.420483Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config 2018-06-07 13:00:03.692+0000: shutting down, reason=failed physical Host: OS-Version:RHEL - 7 - 4.1708.el7.centos Kernelversion: 3.10.0 - 693.21.1.el7.x86_64 KVM-Version: 2.9.0 - 16.el7_4.14.1 LIBVIRT-Version: libvirt-3.2.0-14.el7_4.9 VDSM-Version:vdsm-4.19.45-1.el7.centos Kernel Features:PTI: 1, IBPB: 0, IBRS: 0 Hans-Joachim
