Workarounds for the time being: replace <features> <gic version='3'/> </features> with <features> <gic version='2'/> </features> (preferred) or replace all <address type='pci' [...]/> with <address type='virtio-mmio'/> You can control these settings at install time, when using virt-install, with $ virt-install \ --feature gic_version=2 \ [...] and $ virt-install \ --disk [...],address.type=virtio-mmio \ --network [...],address.type=virtio-mmio \ [...] respectively. The fix has been merged upstream and is part of the 3.4.0 release. commit bc07101a7c2cd2ce07ad1ca28c47e0a7cde5625d Author: Andrea Bolognani <abologna> Date: Fri May 12 13:29:57 2017 +0200 qemu: Use GICv2 for aarch64/virt TCG guests There are currently some limitations in the emulated GICv3 that make it unsuitable as a default. Use GICv2 instead. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1450433 Signed-off-by: Andrea Bolognani <abologna> |
