Hi all,
> This patch adds needs_driver field in kvm testcases to check for kvm driver
@Kushal Thanks for your patch. very nit: s/needs_driver/needs_drivers/
(can be changed before merge).
Implements: https://github.com/linux-test-project/ltp/issues/1219
@Martin Is it enough to have kvm driver? Or do tests depend on any of specific
kvm kernel config options (not only from virt/kvm/Kconfig, but arch dependent
configs e.g. CONFIG_KVM_GUEST=y from arch/x86/Kconfig ?)
Kind regards,
Petr

Some KVM tests can be run by unprivileged user so those also need a
check whether they have permission to open /dev/kvm for writing. But
that can be fixed in a separate patch. Let's merge this one with the
commit message fix.
