Libvirt assumes that a SCSI bus can fit up to 8 devices (including controller itself), except for so called wide bus which can accommodate up to 16 devices (again, including controller). This plays important role when computing 'drive' address in virDomainDiskDefAssignAddress(). So far, the only driver that enables wide SCSI bus is VMX. But with newer releases, ESX is capable of "super wide" bus (64 devices). We can blindly bump the limit in our code because then we would compute address that's invalid for older ESX versions that we still want to support. Unfortunately, I haven't found a better place where to store this than virDomainDef. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
