Now that strange arm64 hang is found to be QEMU bug, I'll repost. Since arm64 requires Thomas's uart patch and it is worse affected by the QEMU bug, I will just not build it on arm. The QEMU bug still affects powerpc (and presumably s390x) but it's not causing so much trouble for this test case. I have another test case that can hit it reliably and doesn't cause crashes but that takes some harness and common lib work so I'll send that another time. Since v4: - Don't build selftest-migration on arm. - Reduce selftest-migration iterations from 100 to 30 to make the test run faster (it's ~0.5s per migration).
Thanks, I think the series is ready to go now ... we just have to wait for your QEMU TCG migration fix to get merged first. Or should we maybe mark the selftest-migration with "accel = kvm" for now and remove that line later once QEMU has been fixed?
