------- Comment From xxd...@de.ibm.com 2018-08-01 05:11 EDT------- Finally I could have a look on all the other VMs that migrate successful: RHEL 7U1, kernel 3.10.0-229.20.1.ael7b.ppc64le RHEL 7U3, kernel 3.10.0-514.6.1.el7.ppc64le RHEL 7U3, kernel 3.10.0-862.3.2.el7.ppc64 SLES 12SP1, kernel 3.12.49-11-default SLES 12SP2, kernel 4.4.21-69-default Ubuntu 16.04.1 LTS, kernel 4.4.0-31-generic
So Ubuntu 18.04 was the first with a kernel really newer than that of the hypervisor (the SLES 12SP2 kernel is only slightly newer, but still a 4.4) I can also do some tests with RHEL 7U5, SLES 12SP3, SLES 15 and Ubuntu 16.10. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1783140 Title: KVM live migration fails Status in The Ubuntu-power-systems project: New Status in linux package in Ubuntu: New Status in qemu package in Ubuntu: Incomplete Bug description: Environment: 2 POWER8 with Ubuntu 16.04.4 LTS as KVM hypervisor. 1 KVM guest with Ubuntu 18.04 LTS.
