[libvirt] [PATCH 6/6] sysinfo: implement qemu support

Tue Feb 8 00:08:50 UTC 2011
* src/util/sysinfo.h (virSysinfoFormat): New prototype.
* src/conf/domain_conf.c (virDomainSysinfoDefFormat): Move guts...
* src/util/sysinfo.c (virSysinfoFormat): ...into new function.
* src/libvirt_private.syms: Export it.
* src/qemu/qemu_driver.c (qemuGetSysinfo): New function.
(qemuDriver): Install it.
---
Tested both with qemu:///system (works!) and qemu:///session
(error: unsupported configuration: Host SMBIOS information is not available)
The prefix hack is necessary so that I can use "" or " " as
the leading indentation, depending on host sysinfo vs. domain,
so it's not quite straight code motion.
