No problem to do some more tests with KVM guests (working Mon, Wed and Fri). We also plan to update the KVM hosts to 18.04.1, but have no fixed date for that. If there are incompatibilities between kernel 4.4 and 4.15, would I maybe risk that then I cannot migrate 16.04 guests any longer? Did anyone tests this case? The other bottomside of the upgrade would be that I cannot help any longer with tests on 16.04 hypervisors. -- 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.
