[libvirt] feature?
by Gene Czarcinski 10 Oct '12

10 Oct '12

By accident I had virtual guests running where the ip6 network definition was different than the one specified in the network xml file ... and it worked! Of course I did get an "extra" network address on the interface (due I assume to radvd) but it worked. Now, this is really an isolated network and I like this as a feature. For "regular" private or isolated virtual networks, the virtualization host can still get to any guest and any network ... except the ones where I had forgot to update the virtual network xml. comments?

[libvirt] [PATCH 0/2] Cleanly save session VMs on logout/shutdown
by Alexander Larsson 10 Oct '12

10 Oct '12

Atm, when you exit the sessin (via logout or shutdown for instance) we just leave the qemu:///session handling libvirtd process around, including any running VMs. This is not particularly nice, as there is no way to know that the VMs are running, and you risk data loss if you shutdown while the VMs are running. This new version is basically the same as the previous, except it runs inside libvirtd, and it exits libvirtd too after saving the VMs. Alexander Larsson (2): virdbus: Add virDBusGetSessionBus helper Shut down session libvirtd cleanly daemon/libvirtd.c | 244 +++++++++++++++++++++++++++++++++++++++++++++++ src/libvirt_private.syms | 1 + src/util/virdbus.c | 84 ++++++++++++---- src/util/virdbus.h | 1 + 4 files changed, 310 insertions(+), 20 deletions(-) -- 1.7.12.1

[libvirt] [PATCH] Make virInitialize thread safe
by Daniel P. Berrange 10 Oct '12

10 Oct '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> Currently there is a restriction that multi-threaded applications must manually call virInitialize, before threads start using libvirt, because it is not thread-safe. By switching it to use a virOnceControl initializer we gain thread safety, and thus applications no longer need to manually call it. They can rely on virConnectOpen invoking it for them.

[libvirt] Schedule for the next release: 1.0.0
by Daniel Veillard 10 Oct '12

10 Oct '12

After checking with Dan and other developpers, there is some agreement that we should finally bump the major release number, and we would like to do it beginning of November i.e. in sync for the next release. As usual all API and ABIs will be kept, this is just a numbering issue ! To try to avoid if possible another "brown paper bag" release just after 1.0.0, it seems logical to extend the testing period a bit, to a week and a half. So be prepared to enter freeze for 1.0.0 around the 24th in a couple of weeks, and celebrate around Nov 2 !

[libvirt] [PATCH] libvirt: Change maximum CPU per node calculation.
by Viktor Mihajlovski 10 Oct '12

10 Oct '12

The macro VIR_NODEINFO_MAXCPUS computes the maximum number of supported CPUs for a node as the product of sockets, cores and threads from the virNodeInfo structure. Since topology cannot be discovered for offline CPUs, any of the values for sockets, cores or threads can be wrong (too small). As a consequence the per-VCPU CPU masks are truncated incorrectly and it's impossible to correlate the bits in the masks with actual CPUs on the host. Example: Host has 3 logical CPUs, 1 socket, 3 cores, 1 thread. Guest has 1 virtual CPU and is started while all 3 host CPUs are online. $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.4s CPU Affinity: yyy $ echo 0 > /sys/devices/system/cpu/cpu1/online $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.5s CPU Affinity: y- The correct display for CPU affinity would have been y-y, as the guest continues to use CPUs 0 and 2. This is not a display problem only, because it is also not possible to explicitly pin the virtual CPU to host CPUs 0 and 2, due to the truncated CPU mask. To prevent this, the following changes have been made: 1. In virNodeParseNode count all logical CPUs, offline or online and pass them back in a new argument 'maxcpus'. 2. Extend the virNodeInfo struct with a new member 'maxcpus' containing the number of all logical CPUs, online and offline. 3. Change the macro VIR_NODEINFO_MAXCPUS to return virNodeInfo.maxpus Signed-off-by: Viktor Mihajlovski <mihajlov(a)linux.vnet.ibm.com> --- include/libvirt/libvirt.h.in | 3 ++- src/nodeinfo.c | 17 +++++++++++++---- src/remote/remote_protocol.x | 1 + src/remote_protocol-structs | 1 + 4 files changed, 17 insertions(+), 5 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 81f12a4..16265b5 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -445,6 +445,7 @@ struct _virNodeInfo { total number of CPU sockets otherwise */ unsigned int cores; /* number of cores per socket */ unsigned int threads;/* number of threads per core */ + unsigned int maxcpus;/* number of maximum cpus - online and offline */ }; /** @@ -1039,7 +1040,7 @@ int virDomainMigrateGetMaxSpeed(virDomainPtr domain, */ -#define VIR_NODEINFO_MAXCPUS(nodeinfo) ((nodeinfo).nodes*(nodeinfo).sockets*(nodeinfo).cores*(nodeinfo).threads) +#define VIR_NODEINFO_MAXCPUS(nodeinfo) ((nodeinfo).maxcpus) /** * virNodeInfoPtr: diff --git a/src/nodeinfo.c b/src/nodeinfo.c index c0e60d8..2e9c111 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -202,9 +202,11 @@ CPU_COUNT(cpu_set_t *set) /* parses a node entry, returning number of processors in the node and * filling arguments */ static int -virNodeParseNode(const char *node, int *sockets, int *cores, int *threads) +virNodeParseNode(const char *node, int *sockets, int *cores, + int *threads, int *cpus) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4) + ATTRIBUTE_NONNULL(5) { int ret = -1; int processors = 0; @@ -223,6 +225,7 @@ virNodeParseNode(const char *node, int *sockets, int *cores, int *threads) *threads = 0; *cores = 0; *sockets = 0; + *cpus = 0; if (!(cpudir = opendir(node))) { virReportSystemError(errno, _("cannot opendir %s"), node); @@ -275,6 +278,8 @@ virNodeParseNode(const char *node, int *sockets, int *cores, int *threads) if (sscanf(cpudirent->d_name, "cpu%u", &cpu) != 1) continue; + (*cpus)++; + if ((online = virNodeGetCpuValue(node, cpu, "online", true)) < 0) goto cleanup; @@ -348,7 +353,7 @@ int linuxNodeInfoCPUPopulate(FILE *cpuinfo, char line[1024]; DIR *nodedir = NULL; struct dirent *nodedirent = NULL; - int cpus, cores, socks, threads; + int cpus, cores, socks, threads, maxcpus; unsigned int node; int ret = -1; char *sysfs_nodedir = NULL; @@ -358,6 +363,7 @@ int linuxNodeInfoCPUPopulate(FILE *cpuinfo, nodeinfo->mhz = 0; nodeinfo->cores = 0; nodeinfo->nodes = 0; + nodeinfo->maxcpus = 0; /* Start with parsing CPU clock speed from /proc/cpuinfo */ while (fgets(line, sizeof(line), cpuinfo) != NULL) { @@ -470,12 +476,13 @@ int linuxNodeInfoCPUPopulate(FILE *cpuinfo, } if ((cpus = virNodeParseNode(sysfs_cpudir, &socks, - &cores, &threads)) < 0) + &cores, &threads, &maxcpus)) < 0) goto cleanup; VIR_FREE(sysfs_cpudir); nodeinfo->cpus += cpus; + nodeinfo->maxcpus += maxcpus; if (socks > nodeinfo->sockets) nodeinfo->sockets = socks; @@ -505,7 +512,8 @@ fallback: goto cleanup; } - if ((cpus = virNodeParseNode(sysfs_cpudir, &socks, &cores, &threads)) < 0) + if ((cpus = virNodeParseNode(sysfs_cpudir, &socks, &cores, + &threads, &maxcpus)) < 0) goto cleanup; nodeinfo->nodes = 1; @@ -513,6 +521,7 @@ fallback: nodeinfo->sockets = socks; nodeinfo->cores = cores; nodeinfo->threads = threads; + nodeinfo->maxcpus = maxcpus; done: /* There should always be at least one cpu, socket, node, and thread. */ diff --git a/src/remote/remote_protocol.x b/src/remote/remote_protocol.x index b0b530c..40883d0 100644 --- a/src/remote/remote_protocol.x +++ b/src/remote/remote_protocol.x @@ -465,6 +465,7 @@ struct remote_node_get_info_ret { /* insert@1 */ int sockets; int cores; int threads; + int maxcpus; }; struct remote_get_capabilities_ret { diff --git a/src/remote_protocol-structs b/src/remote_protocol-structs index 4d2627a..8fece92 100644 --- a/src/remote_protocol-structs +++ b/src/remote_protocol-structs @@ -144,6 +144,7 @@ struct remote_node_get_info_ret { int sockets; int cores; int threads; + int maxcpus; }; struct remote_get_capabilities_ret { remote_nonnull_string capabilities; -- 1.7.0.4
