>From 7db513698bfcc30d2d0b020c3fcf9e0337c66ff4 Mon Sep 17 00:00:00 2001 From: Anirban Chakraborty <abchak(a)juniper.net> Date: Wed, 12 Nov 2014 14:24:43 -0800 Subject: [PATCH] network: Add network bandwidth support to ethernet interfaces Ethernet interfaces in libvirt currently do not support bandwidth setting. For example, following xml file for an interface will not apply these settings to corresponding qdiscs. <interface type="ethernet"> <mac address="02:36:1d:18:2a:e4"/> <model type="virtio"/> <script path=""/> <target dev="tap361d182a-e4"/> <bandwidth> <inbound average="984" peak="1024" burst="64"/> <outbound average="2000" peak="2048" burst="128"/> </bandwidth> </interface> Signed-off-by: Anirban Chakraborty <abchak(a)juniper.net> --- src/conf/netdev_bandwidth_conf.c | 14 ++++++++++- src/conf/netdev_bandwidth_conf.h | 25 +++++++++++++++++++ src/libvirt_private.syms | 1 + src/lxc/lxc_driver.c | 8 +++++++ src/lxc/lxc_process.c | 52 +++++++++++++++++++++++----------------- src/qemu/qemu_command.c | 16 ++++++++----- src/qemu/qemu_hotplug.c | 12 ++++++++++ src/qemu/qemu_process.c | 4 ++++ src/util/virnetdevmacvlan.c | 10 -------- src/util/virnetdevmacvlan.h | 1 - 10 files changed, 104 insertions(+), 41 deletions(-) diff --git a/src/conf/netdev_bandwidth_conf.c b/src/conf/netdev_bandwidth_conf.c index 2e5b564..63a39e3 100644 --- a/src/conf/netdev_bandwidth_conf.c +++ b/src/conf/netdev_bandwidth_conf.c @@ -25,7 +25,6 @@ #include "netdev_bandwidth_conf.h" #include "virerror.h" #include "viralloc.h" -#include "domain_conf.h" #include "virstring.h" #define VIR_FROM_THIS VIR_FROM_NONE @@ -269,3 +268,16 @@ virNetDevBandwidthFormat(virNetDevBandwidthPtr def, virBufferPtr buf) cleanup: return ret;

[libvirt] [RFC: PATCH 0/2] Display allocation during dumpxml
by Eric Blake 18 Nov '14

18 Nov '14

I'm still working on code to populate the latest numbers for each disk of a domain, including getting numbers for offline domains, but have confirmed that with these two patches alone I'm able to see <capacity> and <allocation> numbers for block volumes of live domains (thanks to how we populate backing chain information). So while there are more patches to come, I'd like to get review started on my proposed API addition.

[libvirt] [PATCH v2 0/4] use the 'vram' attribute for QEMU video devices
by Pavel Hrdina 18 Nov '14

18 Nov '14

There are some changes from the first version. We will not have a new 'vgamem' attribute for video devices because we can use the 'vram' attribute. So far for QEMU the 'vram' is used only to set the secondary ram for QXL which seems to be correct as the secondary ram is used for pixmaps and surfaces. The 'vgamem_mb' parameter for QXL sets the VGA framebuffer size, but the VGA mode in QXL is used only as fallback if the OS doesn't have any QXL drivers or before the drivers are loaded. The VGA framebuffer is part of the first ram for QXL and for that we have 'ram' attribute. The rest of the first ram is memory for rendering commands and it's data. Default VGA framebuffer size is 8MB which is sufficient. Other QEMU video devices have only 'vgamem_mb' parameter and we will use the 'vram' attribute to set the size of video memory as it's used also for other hypervisors. The first two patches clean the usage of vram attribute and improve the documentation and the rest two patches implements usage of 'vram' attribute for remaining QEMU video devices.

[libvirt] How can I get drive_mirror migration progress with non-shared storage on KVM ?
by Wang Rui 18 Nov '14

18 Nov '14

Hi, I want to get a total progress(memory + storage). In none drive mirror migration, I can use virDomainGetJobInfo API to get the total progress. But in drive mirror migration, it seems that I must get file progress by virDomainGetBlockJobInfo and momery progress by virDomainGetJobInfo separately. So does the job status. Is there a way to get the total progress and job status? Thanks.

[libvirt] [PATCH v3] leaseshelper: improvements to support all events
by Nehal J Wani 17 Nov '14

17 Nov '14

This patch enables the helper program to detect event(s) triggered when there is a change in lease length or expiry and client-id. This transfers complete control of leases database to libvirt and obsoletes use of the lease database file (<network-name>.leases). That file will not be created, read, or written. This is achieved by adding the option --leasefile-ro to dnsmasq and passing a custom env var to leaseshelper, which helps us map events related to leases with their corresponding network bridges, no matter what the event be. Also, this requires the addition of a new non-lease entry in our custom lease database: "server-duid". It is required to identify a DHCPv6 server. Now that dnsmasq doesn't maintain its own leases database, it relies on our helper program to tell it about previous leases and server duid. Thus, this patch makes our leases program honor an extra action: "init", in which it sends the known info in a particular format to dnsmasq by printing it to stdout. --- This is compatible with libvirt 1.2.6 as only additions have been introduced, and the old leases file (*.status) will still be supported. v3: * Add server-duid as an entry in the lease object for every ipv6 lease. * Remove unnecessary variables and double copies. * Take value from DNSMASQ_OLD_HOSTNAME if hostname is not known. v2: http://www.redhat.com/archives/libvir-list/2014-July/msg01109.html v1: https://www.redhat.com/archives/libvir-list/2014-July/msg00568.html src/network/bridge_driver.c | 3 + src/network/leaseshelper.c | 132 +++++++++++++++++++++++++++++++++++--------- 2 files changed, 109 insertions(+), 26 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 965fdec..b578b3a 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -1288,7 +1288,10 @@ networkBuildDhcpDaemonCommandLine(virNetworkObjPtr network, cmd = virCommandNew(dnsmasqCapsGetBinaryPath(caps)); virCommandAddArgFormat(cmd, "--conf-file=%s", configfile); + /* Libvirt gains full control of leases database */ + virCommandAddArgFormat(cmd, "--leasefile-ro"); virCommandAddArgFormat(cmd, "--dhcp-script=%s", leaseshelper_path); + virCommandAddEnvPair(cmd, "VIR_BRIDGE_NAME", network->def->bridge); *cmdout = cmd; ret = 0; diff --git a/src/network/leaseshelper.c b/src/network/leaseshelper.c index c8543a2..e984cbb 100644 --- a/src/network/leaseshelper.c +++ b/src/network/leaseshelper.c @@ -50,6 +50,12 @@ */ #define VIR_NETWORK_DHCP_LEASE_FILE_SIZE_MAX (32 * 1024 * 1024) +/* + * Use this when passing possibly-NULL strings to printf-a-likes. + * Required for unknown parameters during init call. + */ +#define EMPTY_STR(s) ((s) ?

[libvirt] [PATCH] qemu: Resolve Coverity UNINIT
by John Ferlan 17 Nov '14

17 Nov '14

For some reason, commit id '72b4151f' triggered a Coverity uninitialized 'reply' variable check when referenced within the for loop. It seems Coverity doesn't know that flags will have to be either AFFECT_LIVE or AFFECT_CONFIG after the virDomainLiveConfigHelperMethod call. By adding a "sa_assert()" to confirm that fact, Coverity is happy again. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- NOTE: Using "sa_assert(flags & (VIR_DOMAIN_AFFECT_LIVE | VIR_DOMAIN_AFFECT_CONFIG)); did not clear the error - only the two separate checks using the ||.

[libvirt] ANNOUNCE: libvirt 1.1.3.8 maintenance release
by Cole Robinson 16 Nov '14

16 Nov '14

libvirt 1.1.3.8 maintenance release is now available. This is libvirt 1.1.3 with additional bugfixes that have accumulated upstream since the initial release. This release can be downloaded at: http://libvirt.org/sources/stable_updates/libvirt-1.1.3.8.tar.gz I originally release 1.1.3.7, but then when I attempted to rebuild it I hit a compile error. Really not sure why it didn't hit me during before. So 1.1.3.8 is a brown paper bag release. Changes in version 1.1.3.7: * CVE-2014-7823: dumpxml: security hole with migratable flag * node_device_udev: Try harder to get human readable vendor:product * tests: don't fail with newer gnutls * Fix crash in virsystemdtest with dbus 1.7.6 * domain_conf: fix domain deadlock * CVE-2014-3633: qemu: blkiotune: Use correct definition when looking up disk Changes in version 1.1.3.8: * tests: Fix compilation For info about past maintenance releases, see: http://wiki.libvirt.org/page/Maintenance_Releases Thanks, Cole
