[Qemu-devel] [PATCH] tests/prom-env: Bump the timeout, and test pseries only in slow mode

[Thomas Huth <thuth@redhat.com>]

If QEMU has been compiled with the flags --enable-tcg-interpreter and
--enable-debug, the guest is running incredibly slow. The prom-env
test is approximately 10 times slower than normal in this case, and
it takes up to 500 seconds until the test with the pseries machine
finishs. While we should still look for ways to speed up the test
on the pseries machine here, let's bump the timeout to 600 seconds to
allow the test to pass with this unusal configuration already now.
Also move the pseries test into the "slow" category - since it is
really a very slow test.
