From 5c84a2c439afb2a6a5aa69ccd2d7e2ecdb1d18cf Mon Sep 17 00:00:00 2001 Message-Id: <5c84a2c439afb2a6a5aa69ccd2d7e2ecdb1d18cf.1574270987.git.crobinso@redhat.com> From: Laurent Vivier Date: Wed, 20 Nov 2019 18:09:55 +0100 Subject: [PATCH] pseries: disable migration-test if /dev/kvm cannot be used On ppc64, migration-test only works with kvm_hv, and we already have a check to verify the module is loaded. kvm_hv module can be loaded in memory and /sys/module/kvm_hv exists, but on some systems (like build systems) /dev/kvm can be missing (by administrators choice). And as kvm_hv exists test-migration is started but QEMU falls back to TCG because it cannot be used: Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory Back to tcg accelerator And as the test is done with TCG, it fails. As for s390x, we must check for the existence and the access rights of /dev/kvm.
