[libvirt] [PATCH] add <bootp server="...">
by Paolo Bonzini 28 Oct '09

28 Oct '09

This patch adds an optional attribute to the <bootp> tag, that allows to specify a TFTP server address other than the address of the DHCP server itself. This can be used to forward the BOOTP settings of the host down to the guest. This is something that configurations such as Xen's default network achieve naturally, but must be done manually for NAT. 2009-10-22 Paolo Bonzini <pbonzini(a)redhat.com> * docs/formatnetwork.html.in: Document new attribute. * docs/schemas/network.rng: Add it to schema. * src/conf/network_conf.h: Add it to struct. * src/conf/network_conf.c: Add it to parser and pretty printer. * src/network/bridge_driver.c: Put it in the dnsmasq command line. * tests/networkxml2xmlin/netboot-proxy-network.xml: New. * tests/networkxml2xmlout/netboot-proxy-network.xml: New. * tests/networkxml2xmltest.c: Add the new test. --- docs/formatnetwork.html.in | 15 ++++++++++----- docs/schemas/network.rng | 3 +++ src/conf/network_conf.c | 9 ++++++++- src/conf/network_conf.h | 1 + src/network/bridge_driver.c | 9 +++++++-- tests/networkxml2xmlin/netboot-proxy-network.xml | 13 +++++++++++++ tests/networkxml2xmlout/netboot-proxy-network.xml | 13 +++++++++++++ tests/networkxml2xmltest.c | 1 + 8 files changed, 56 insertions(+), 8 deletions(-) create mode 100644 tests/networkxml2xmlin/netboot-proxy-network.xml create mode 100644 tests/networkxml2xmlout/netboot-proxy-network.xml diff --git a/docs/formatnetwork.html.in b/docs/formatnetwork.html.in index e471385..eb61f15 100644 --- a/docs/formatnetwork.html.in +++ b/docs/formatnetwork.html.in @@ -142,11 +142,16 @@ name to be given that host by the DHCP server (via the <code>name</code> attribute). <span class="since">Since 0.4.5</span> </dd><dt><code>bootp</code></dt><dd>The optional <code>bootp</code> - element specifies BOOTP options to be provided by the DHCP server. - Only one attribute is supported, <code>file</code>, giving the file - to be used for the boot image).

[libvirt] New APIs for checking some object properties (v2)
by Daniel P. Berrange 28 Oct '09

28 Oct '09

This is a second posting of the proposal from earlier today http://www.redhat.com/archives/libvir-list/2009-October/msg00556.html The changes since last time - Renamed some existing internal APIs which had bad names which clashed with our new public APis. - Fix the comment bugs Daniel mentioned - Change the return status from '> 0' to '1', so we can explicitly add other positive integer return codes if ever required - Implement the new APIs for (nearly) all drivers Daniel

[libvirt] [PATCH 0/2] Fix a couple problems encountered during virInterface testing
by Laine Stump 28 Oct '09

28 Oct '09

When testing all the different possibilities of interfaces with the new netcf release + my latest libvirt patches (ACKed, but not yet committed), I came across some problems, addressed by the following two patches. The first patch is for a bug that crept in due to a last minute change suggested in danpb's review - I missed changing a couple places to account for changing the initial value of "ret". It could alternately be squashed into this patch, which hasn't yet been committed: https://www.redhat.com/archives/libvir-list/2009-October/msg00689.html The second patch loosens up the parsing of vlan, bond, and bridge interface XML because the live config XML doesn't know how to get those items yet. I believe the necessary items can be learned and included by the time for the *next* libvirt release, but think that the new functionality there already is too useful (and too needy of more hands to test) to delay the entire set for that long.
