On some systems, there are two or even more 'OEM Strings'
sections in DMI table. Here's an example of dmidecode output on
such system:
# dmidecode -q -t 11
OEM Strings
String 1: Default string
OEM Strings
String 1: ThunderX2 System
String 2: cavium.com
String 3: Comanche
Now, this poses a problem, because when one tries to obtain
individual strings, they get:
# dmidecode -q --oem-string 1
Default string
ThunderX2 System
# dmidecode -q --oem-string 2
No OEM string number 2
cavium.com
NB, the "No OEM string number 2" is printed onto stderr and
everything else onto stdout. Oh, and trying to get OEM strings
from just one section doesn't fly:
# dmidecode -q -H 0x1d --oem-string 2
Options --string, --type, --handle and --dump-bin are mutually exclusive
This means two things:
1) we have no way of distinguishing OEM strings at the same index
but in different sections,
2) because of how virSysinfoDMIDecodeOEMString() is written, we
fail in querying OEM string that exists in one section but not
in the others (for instance string #2 from example above).
While there's not much we can do about 1), there is something
that can be done about 2) - refine the error condition and make
the function return an error iff there's nothing on stdout and
there's something on stderr.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
