IMHO we can keep the test (with SKIPPED=1) but amend the message, which will start to state inaccurately: # This job is disabled until we release 9.0. The existing # migration-test in 8.2 is broken on aarch64. The fix was already # commited, but it will only take effect once 9.0 is out. IMHO then it won't mean 9.0 will have it fixed, but we'll simply wait for a cpu model that is ready for both kvm+tcg, then we replace "max". For gic_version, I knew 3 was there for quite some time so maybe we can start from that? Or we need suggestions from ARM people. -- Peter Xu
