I'd love to test other operating systems too (FreeBSD does work if I abuse the stuff in tests/vm/ and add a Xen guest mode). But this is enough for now to help catch regressions on the QEMU side.
Especially the polling for the event channel GSI deassertion is likely to be fragile, and in the not-so-distant future I really do want to add an explicit EOI hook in the interrupt controllers; as discussed, VFIO INTx would benefit from that too. When the guest kernel boots with 4 CPUs, it ends up initially targeting the event channel GSI to CPU#2, and then testing the migration. Since nobody evidently cared about the I/OAPIC migration bug in the 7 years since it was introduced with the first split-irqchip support, that fix might as well stay here in this series. v2: https://git.infradead.org/users/dwmw2/qemu.git/shortlog/refs/heads/xenfv-test-2 • Use xen-disk now that the PR adding support for that has been submitted • Include the I/O APIC migration fix, so that we can use -smp 4 v1: https://lore.kernel.org/qemu-devel/20230303125126.1269861-1-dw...@infradead.org/ https://git.infradead.org/users/dwmw2/qemu.git/shortlog/refs/heads/xenfv-test David Woodhouse (3): hw/intc/ioapic: Update KVM routes before redelivering IRQ, on RTE update tests/avocado: Add Fedora 34 distro, including kernel/initrd checksums tests/avocado: Test Xen guest support under KVM hw/intc/ioapic.c | 3 +- tests/avocado/avocado_qemu/__init__.py | 27 ++++++ tests/avocado/xen_guest.py | 147 +++++++++++++++++++++++++++++++++ 3 files changed, 175 insertions(+), 2 deletions(-) create mode 100644 tests/avocado/xen_guest.py
