I'm guessing adding "tcg_only = true", like all other virt machine tests
in this file, should work around this, but I don't really understand the
problem because I can't reproduce it on my aarch64 host (I'm running
"configure --target-list=aarch64-softmmu" followed by "make -j10
check-qtest V=1" in a loop)
Does the attached patch fix it for you?
Thanks,
Jean

Subject: [PATCH] tests/qtest/bios-tables-test: Only run VIOT test on TCG
The VIOT test does not always work under KVM on the virt machine:
PASS 5 qtest-aarch64/bios-tables-test /aarch64/acpi/virt/oem-fields
qemu-system-aarch64: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid
argument
Broken pipe
Make it TCG only.
