[Qemu-devel] [PATCH v2] iotests: drop unnecessary accel=kvm in 238

[Stefan Hajnoczi]

Test 238 does not require the kvm accelerator.  TCG works fine.

Use the default accelerator instead of requiring kvm.

Vladimir, I have dropped the 235 change because I don't have time to
figure out the kvm/tcg vs qtest differences or add a skip function.
Sorry!

Would it be feasible to change it into "accel=qtest" instead? ... then
this test would also work when QEMU has been compiled with --disable-tcg
and when KVM is not available...

Sure.  I have tested that qtest still triggered the bug when the fix was
merged.

Will fix in v3.
