[libvirt] for initial review: updated doc for DHCPv6
by Gene Czarcinski 03 Nov '12

03 Nov '12

I have taken a shot at updating the libvirt documentation for DHCPv6 support and am attaching the resulting patch. This is a sanity check and not a submission. I will submit the documentation patch when I submit the patches which actually do the work. Is there any other documentation I should be updating? Gene

[libvirt] Release of libvirt-1.0.0
by Daniel Veillard 02 Nov '12

02 Nov '12

Well we just crossed that important milestone in the life of any project, so congratulation everybody the 1.0.0 release is out !!! For a bit of history, this is actually the 7th birthday of the project accounted from the first commit, on Nov 2 2005, public from day one ! CVS converted commit labelled "Initial revision" 2005-11-02 20:50:21 At the time I had one hypervisor (Xen) to play with, and except the general idea and some of the earlier entry point there is nothing left from that first commit, and that is just fine :-) ! Anyway back to useful informations, the release is as usual at: ftp://libvirt.org/libvirt/ as a tarball and signed rpms. For just over a month of development we are at nearly 350 commits so the pace is apparently not slowing down! There is a number of important improvements, but for a change I would like to point out the silent work of our translators communities, work being done in the framework of Transifex: https://www.transifex.com/projects/p/libvirt/ we have around 10 languages with near complete translation, historically we had 2 complete localization : japanese and ukrainian at 100% and updating within hours of a new pot source file being pushed, in the last month 5 new indian languages have completed, and various others have made significant improvements. So to those group of people helping mostly silently in the background I want to say Thank You, your work makes a difference !!! Features: - virNodeGetCPUMap: Define public API.

[libvirt] [PATCH] cpumap: optimize for clients that don't need online count
by Eric Blake 02 Nov '12

02 Nov '12

It turns out that calling virNodeGetCPUMap(conn, NULL, NULL, 0) is both useful, and with Viktor's patches, common enough to optimize. Since this interface hasn't been released yet, we can change the RPC call. * src/nodeinfo.c (nodeGetCPUMap): Avoid bitmap when not needed. * src/remote/remote_protocol.x (remote_node_get_cpu_map_args): Supply two separate flags for needed arguments. * src/remote/remote_driver.c (remoteNodeGetCPUMap): Update caller. * daemon/remote.c (remoteDispatchNodeGetCPUMap): Likewise. * src/remote_protocol-structs: Regenerate. --- This has to be applied before 1.0.0 if we want it; otherwise the change to RPC wire protocol will render this patch an ABI break. I thought of one alternative, that wouldn't change the RPC size, but still would be a difference. That would be using the old need_results int as a bitmap of which of the two arguments are needed, instead of just a 1 or 0. But even that is risky enough that it should get in before we commit to this interface. daemon/remote.c | 8 ++++---- src/nodeinfo.c | 3 +++ src/remote/remote_driver.c | 3 ++- src/remote/remote_protocol.x | 3 ++- src/remote_protocol-structs | 3 ++- 5 files changed, 13 insertions(+), 7 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index 7a9df60..340d07d 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -4578,7 +4578,7 @@ remoteDispatchNodeGetCPUMap(virNetServerPtr server ATTRIBUTE_UNUSED, remote_node_get_cpu_map_ret *ret) { unsigned char *cpumap = NULL; - unsigned int online; + unsigned int online = 0; unsigned int flags; int cpunum; int rv = -1; @@ -4592,13 +4592,13 @@ remoteDispatchNodeGetCPUMap(virNetServerPtr server ATTRIBUTE_UNUSED, flags = args->flags; - cpunum = virNodeGetCPUMap(priv->conn, args->need_results ? &cpumap : NULL, - &online, flags); + cpunum = virNodeGetCPUMap(priv->conn, args->need_map ? &cpumap : NULL, + args->need_online ? &online : NULL, flags); if (cpunum < 0) goto cleanup; /* 'serialize' return cpumap */ - if (args->need_results) { + if (args->need_map) { ret->cpumap.cpumap_len = VIR_CPU_MAPLEN(cpunum); ret->cpumap.cpumap_val = (char *) cpumap; cpumap = NULL; diff --git a/src/nodeinfo.c b/src/nodeinfo.c index 35c5f96..3348ae7 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -1277,6 +1277,9 @@ nodeGetCPUMap(virConnectPtr conn ATTRIBUTE_UNUSED, virCheckFlags(0, -1); + if (!cpumap && !online) + return nodeGetCPUCount(); + if (!(cpus = nodeGetCPUBitmap(&maxpresent))) goto cleanup; diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index 71218f0..5eca0fa 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -5793,7 +5793,8 @@ remoteNodeGetCPUMap(virConnectPtr conn, remoteDriverLock(priv); - args.need_results = !!cpumap; + args.need_map = !!cpumap; + args.need_online = !!online; args.flags = flags; memset (&ret, 0, sizeof(ret)); diff --git a/src/remote/remote_protocol.x b/src/remote/remote_protocol.x index 765ffcd..d6ac3c1 100644 --- a/src/remote/remote_protocol.x +++ b/src/remote/remote_protocol.x @@ -2671,7 +2671,8 @@ struct remote_node_get_memory_parameters_ret { }; struct remote_node_get_cpu_map_args { - int need_results; + int need_map; + int need_online; unsigned int flags; }; diff --git a/src/remote_protocol-structs b/src/remote_protocol-structs index 567864a..6fe7213 100644 --- a/src/remote_protocol-structs +++ b/src/remote_protocol-structs @@ -2127,7 +2127,8 @@ struct remote_node_get_memory_parameters_ret { int nparams; }; struct remote_node_get_cpu_map_args { - int need_results; + int need_map; + int need_online; u_int flags; }; struct remote_node_get_cpu_map_ret { -- 1.7.11.7

02 Nov '12

There are currently three significant libvirt patches I am involved with: 1. Change so that dnsmasq parameters are in a conf file instead of on the command line. 2. A small patch to add dnsmasq parameter interface= 3. A significant patch to add DHCPv6 support to libvirt. A concern has been raised about the compatibility of my patches with dnsmasq-2.48 which is the version on CentOS 6 and RHEL 6. While something like libvirt-1.0.0 is not officially supported, there is a strong desire not to get in the way of individuals back-porting it. Plan A: Install CentOS 6.3 into a virtual guest. Apparently, the current virt-manager has some problems running CentOS 6.3. Since I was here to drain a swap, I decided not to go after this alligator. Plan B: Get a the src.rpm for dnsmasq-2.48 from CentOS and build it on Fedora 17. Then, using a Fedora 17 virtual guest, downgrade install dnsmasq-2.48 on it. I then took four of my virtual dnsmasq conf-files than I use, slightly modify them to use interface=eth2 and common pid, hostsfile, addnhosts, and leases files. I then fed each of these configuration files to dnsmasq-2.48. Everything worked except for the one which had an IPv6 dhcp-range specified. That was not surprising dnsmasq-2.48 only supports IPv6 for dns. If someone has some additional tests they would like run, please say so. My recommendation: Incorporate my patches [when I finish the DHCPv6 one and resubmit the others]. Add (somewhere?) a warning to backporters that they will need to update their dnsmasq packages to actually do DHCPv6 but otherwise, earlier versions such as dnsmasq-2.48 will be compatible. Comments? Suggestions? Gene

To celebrate our 1.0.0 release / 7th birthday, I have prepared a new annimation of libvirt development history using gource, and made it available here: https://www.youtube.com/watch?v=TKynN8TwC0M Notice the big increase in number of contributors after the switch to GIT in mid-2009.

[libvirt] [PATCH] logging: Do not redefine mkostemp on uclibc
by Jiri Denemark 02 Nov '12

02 Nov '12

An obsolete version of the patch that fixed building on systems with uclibc (4dbd6e96) was accidentally pushed as part of the release commit (2b435c15). Since this obsolete patch made syntax-check, commit 30b398d5 was pushed to fix that issue. But the real fix is to actually remove the offending code. This patch reverts commit 30b398d5 and the relevant part of 2b435c15. --- cfg.mk | 2 -- src/util/logging.c | 5 ----- 2 files changed, 7 deletions(-) diff --git a/cfg.mk b/cfg.mk index 963f642..cda04e4 100644 --- a/cfg.mk +++ b/cfg.mk @@ -817,5 +817,3 @@ exclude_file_name_regexp--sc_unmarked_diagnostics = \ ^(docs/apibuild.py|tests/virt-aa-helper-test)$$ exclude_file_name_regexp--sc_size_of_brackets = cfg.mk - -exclude_file_name_regexp--sc_prohibit_mkstemp = ^src/util/logging\.c$$ diff --git a/src/util/logging.c b/src/util/logging.c index 27bd74c..dd43842 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -58,11 +58,6 @@ #define VIR_FROM_THIS VIR_FROM_NONE -#ifdef __UCLIBC__ -/* uclibc does not implement mkostemp GNU extention */ -# define mkostemp(x,y) mkstemp(x) -#endif - VIR_ENUM_DECL(virLogSource) VIR_ENUM_IMPL(virLogSource, VIR_LOG_FROM_LAST, "file", -- 1.7.12.4

[libvirt] Proposed: optionally enable dnsmasq logging
by Gene Czarcinski 02 Nov '12

02 Nov '12

Note: the solutions listed below will all work with dnsmasq-2.48. Sometimes it is very difficult to determine what a dnsmasq problem is when it does not work as expected. Dnsmasq has to options for logging: log-quiries and log-dhcp. Either or both can be enabled. By default, neither is enabled. 1. Add an option or options to libvirtd.conf which will enable the logging on all started dnsmasq processes. While this is doable, it will also produce a great deal of syslog mesages if more than one dnsmasq process is running. 2. Add an option to libvirtd.conf which will enable the solutions given below. By default, it will not be enabled. 3. Add dnsmasq parameter conf-dir= to specify a directory (under the same directory as the leases file) where the administrator/user can add a file which contains log-queries and/or log-dhcp. 4. Add the dnsmasq parameter conf-file= to specify an additional configuration file. This would be under the same directory as the leases file and have a name of something like: <network_name>.conf-2. If the file already existed, nothing would be done. If the file did not exist, a zero-length file would be created. Currently, I favor ether 4 or the combination of 4 and 2. Note: dnsmasq would only read this secondary configuration file when it is started or restarted. Comments? Suggestions? Whatever? Gene

[libvirt] [PATCH 0/2] Add lock in libxl
by Bamvor Jian Zhang 02 Nov '12

02 Nov '12

These two patches implement a lock for long-running job(save, dump and migration) and normal job which will return in short time but maybe affect the state of virtual machine. With these patches, the normal job could not execute while the long-ruuning job or other normal job is running. In order to tracking these job, job type for normal job and long-ruuning job(will be called as async job in code) is defined. The abort job is called while user want to cancel such async job. Note that there is no cancellation function for async job in xenlight stack. So, abort function just block the cancellation of user. Update compare to v1: 1, remove migration relative job functions from lock patch. 2, update comments according to upstream's comments.
