Subject: Use qemu-kvm in documentation instead of qemu-system-<arch>
Patchwork-id: 62380
O-Subject: [RHEV-7.1 qemu-kvm-rhev PATCHv4] Use qemu-kvm in documentation instead of qemu-system-i386
Bugzilla: 1140620
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
RH-Acked-by: Markus Armbruster <armbru@redhat.com>
RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>
From: Miroslav Rezanina <mrezanin@redhat.com>
We change the name and location of qemu-kvm binaries. Update documentation
to reflect this change. Only architectures available in RHEL are updated.
