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

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".
