[libvirt] QEMU CPU model versioning/compatibility (was Re: KVM call minutes July 31th)

Moving the CPU models inside the code is a step backwards, IMO. I don't think loading some kind of data from an external file (provided and maintained by QEMU itself) should be considered something special and magic, and make the data there a second-class citizen (that QEMU refuses to give proper support and keep compatibility). But if it will make us stop running in circles every time something related to those files needs to be changed (remember the -no-user-config discussion?), I think I will accept that. -- Eduardo

[libvirt] libvirt: how to set PV-on-HVM drivers??

by zcs

Hi friend. I have a problem about using libvirt now. There is a feather about HVM driver ---PV_on_HVM_drivers, in xm configure, using flag xen_platform_pci can control the feather, but in libvirt I can not find the flags to use pv-on-HVM drivers. So I want to find the answer if the libvirt can control the modules using xml file? thanks a lot. best regards. zhong.chunshan http://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers

[libvirt] [PATCH v2 0/5] Introduce API for dumping domain IP addresses

by Michal Privoznik

This feature has been requested for a very long time. However, we had to wait for guest agent to obtain reliable results as user might create totally different structure of interfaces than seen from outside (e.g. bonding, virtual interfaces, etc.). That's the main reason why sniffing for domain traffic can return bogus results. Fortunately, qemu guest agent implement requested part for a while so nothing holds us back anymore. To make matters worse, guest OS can assign whatever name to an interface and changing MAC inside guest isn't propagated to the host which in the end see original one. Therefore, finding correlation between interface within guest and the host side end is left as exercise for mgmt applications. This API is called virDomainGetInterfacesAddresses (okay, maybe too many plurals) and returns a XML document containing all interesting data. diff to v1: -switch from struct to XML doc Michal Privoznik (5): Introduce virDomainGetInterfacesAddresses API virsh: Expose virDomainGetInterfacesAddresses qemu_agent: Implement 'guest-network-get-interfaces' command handling qemu: Implement virDomainInterfacesAddresses python: create example for dumping domain IP addresses docs/schemas/interfaces.rng | 57 +++++++++++++++++ examples/python/Makefile.am | 2 +- examples/python/README | 1 + examples/python/domipaddrs.py | 62 +++++++++++++++++++ include/libvirt/libvirt.h.in | 2 + src/driver.h | 4 + src/libvirt.c | 49 +++++++++++++++ src/libvirt_public.syms | 1 + src/qemu/qemu_agent.c | 135 +++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 2 + src/qemu/qemu_driver.c | 68 +++++++++++++++++++++ src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 12 +++- src/remote_protocol-structs | 8 +++ tools/virsh.c | 41 ++++++++++++ tools/virsh.pod | 9 +++ 16 files changed, 452 insertions(+), 2 deletions(-) create mode 100644 docs/schemas/interfaces.rng create mode 100644 examples/python/domipaddrs.py -- 1.7.8.5
