When i run ./run_tests.sh, i get output like this:

SKIP apic-split (qemu: could not open kernel file '_NO_FILE_4Uhere_': No such file or directory) SKIP ioapic-split (qemu: could not open kernel file '_NO_FILE_4Uhere_': No such file or directory) SKIP apic (qemu: could not open kernel file '_NO_FILE_4Uhere_': No such file or directory)
......

Seems like the code below causing of "SKIP" above.

file: scripts/runtime.bash

# We assume that QEMU is going to work if it tried to load the kernel premature_failure()

{
    local log="$(eval $(get_cmdline _NO_FILE_4Uhere_) 2>&1)"

    echo "$log" | grep "_NO_FILE_4Uhere_" |
        grep -q -e "could not load kernel" -e "error loading" &&
        return 1

    RUNTIME_log_stderr <<< "$log"

    echo "$log"
    return 0
}

get_cmdline()
{
local kernel=$1
echo "TESTNAME=$testname TIMEOUT=$timeout ACCEL=$accel
$RUNTIME_arch_run $kernel -smp $smp $opts"
}

function run()
{
...

    last_line=$(premature_failure > >(tail -1)) && {
        print_result "SKIP" $testname "" "$last_line"
        return 77
    }

...
}

Is that proper? What can i do?

What i did:

1. git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
2. cd kvm-unit-tests/
3. git checkout -b next origin/next
4. ./configure
5. make
6. ./run_test.sh

You need https://patchwork.kernel.org/patch/11284587/ for this issue. But I just tried a latest qemu on x86 and see tests are hanging. So that may not be enough to get you running.

Thanks a lot. It's ok to run. The qemu i use is based on the commit "2061735ff09f9d5e67c501a96227b470e7de69b1".

Hi Paolo,

could you maybe apply my patch directly, to avoid that other people run into this issue, too?

Thanks,
Thomas

Yes, I will apply the whole series. I've finished more or less going through QEMU patches.
