[libvirt] Error connecting to virConnectOpen("qemu:///system"); after 20 times
by Pankaj Rawat
Hi,
I am using libvirt api to create an app, I am facing a problem.
I can connect to connection object 20 number of times in programm after that it gives connection object null.
Here is the sample code.
Normally code should run 1000 times but it only runs 20 times
Filename: list.cpp
#include<pthread.h>
#include<stdlib.h>
#include<stdio.h>
#include<malloc.h>
#include <iostream>
#include<string.h>
#include <libvirt/libvirt.h>
#include <libvirt/virterror.h>
static int count;
static void customErrorFunc(void *userdata, virErrorPtr err)
{
}
int main()
{
virConnectPtr conn;
for ( int i=0; i< 1000;i++)
{
conn = virConnectOpen("qemu:///system");
if (conn == NULL) {
fprintf(stderr, "Failed to open connection to qemu:///system\n");
printf("Failed to open connection to qemu:///system\n");
virConnectClose(conn);
return NULL;
}
printf("Hello %d\n",i);
virError err;
virSetErrorFunc(NULL, customErrorFunc);
int j;
int numDomains1,numDomains2,numDomains;
int *activeDomains;
numDomains1 = virConnectNumOfDomains(conn);
activeDomains = (int*)malloc(sizeof(int) * numDomains1);
numDomains1 = virConnectListDomains(conn, activeDomains, numDomains1);
for (int j = 0 ; j < numDomains1 ; j++)
{
virDomainPtr dom;
dom = virDomainLookupByID(conn,activeDomains[j]);
free(dom);
}
free(activeDomains);
count--;
virConnectClose(conn);
}
}
Output:
Hello 0
Hello 1
Hello 2
Hello 3
Hello 4
Hello 5
Hello 6
Hello 7
Hello 8
Hello 9
Hello 10
Hello 11

Hello 14
Hello 15
Hello 16
Hello 17

Failed to open connection to qemu:///system

Can any one tell me where I am going wrong.

[libvirt] [PATCH] python: Fix bindings for virDomainSnapshotGetDomain
by Jiri Denemark
https://bugzilla.redhat.com/show_bug.cgi?id=895882
virDomainSnapshotGetDomain returns snapshot->domain without incrementing
domain's reference counter. The autogenerated python wrapper around this
API did not honor this fact and created a new virDomain object from the
snapshot's domain. When this object is deleted, it calls virDomainFree.
This caused python client to crash when the domain object is accessed
after it has been freed.

[libvirt] [PATCH] build: allow virObject to have no parent
by Eric Blake
When building with static analysis enabled, we turn on attribute
nonnull checking. However, this caused the build to fail with:
../../src/util/virobject.c: In function 'virObjectOnceInit':
../../src/util/virobject.c:55:40: error: null argument where non-null required (argument 1) [-Werror=nonnull]
Creation of the virObject class is the one instance where the
parent class is allowed to be NULL, so making things conditional
will let us keep static analysis checking for all other callers,
without breaking the build on the one exception.
* src/util/virobject.c: Define witness.
* src/util/virobject.h (virClassNew): Use it to force most callers
to pass non-null parameter.
---
I couldn't bring myself to push this under the build breaker rule,
so I'll wait for a review.

[libvirt] [PATCH] util: Remove ATTRIBUTE_NONNULL from virClassNew()
by John Ferlan
When compiling with Coverity, the STATIC_ANALYSIS was set to true which
triggered the ATTRIBUTE_NONNULL check from src/internal.h. Since virClassNew
now expects to be called with NULL under a special condition, this check
is no longer valid.

[libvirt] [PATCH v2] qemu: Support ram bar size for qxl devices
by Alon Levy
Adds a "ram" attribute globally to the video.model element, that changes
the resulting qemu command line only if video.type == "qxl".
<video>
<model type='qxl' ram='65536' vram='65536' heads='1'/>
</video>
That attribute gets a default value of 64*1024. The schema is unchanged
for other video element types.
The resulting qemu command line change is the addition of
-global qxl-vga.ram_size=<ram>*1024
or
-global qxl.ram_size=<ram>*1024
For the main and secondary qxl devices respectively.
The default for the qxl ram bar is 64*1024 kilobytes (the same as the
default qxl vram bar size).
---
changes from v1:
renamed attribute to ram (Eric Blake)
fixes as given by Eric Blake
Did not add any of the suggestions that Gerd made, I think it can be done in a
separate patch and there was no discussion on it yet.

[libvirt] [PATCH] virsh-domain: Refactor error paths for cmdCPUStats
by Peter Krempa
This patch fixes the following issues in the cpu-stats virsh command:
1) Renames label failed_params to no_memory to match coding style
2) Uses proper typed parameter cleanup in error paths to avoid leaks
3) Adds a ret variable and simplifies error labels
4) Changes error message to a slightly more descriptive one and gets rid
of the newline at the end:
Before:
$ virsh cpu-stats tr
error: Failed to virDomainGetCPUStats()
error: Requested operation is not valid: domain is not running
After:
$ tools/virsh cpu-stats tr
error: Failed to retrieve CPU statistics for domain 'tr'
error: Requested operation is not valid: domain is not running

[libvirt] [PATCH 00/14] Resolve more Coverity issues
by John Ferlan
I got answer from someone on the Coverity boards regarding a false positive
related to how VIR_FREE() was operating when passed an address of an address
to some memory, see my note from last week:
https://www.redhat.com/archives/libvir-list/2013-January/msg01353.html
Essentially the issue is the "?:" construct in the VIR_FREE() macro and
Coverity taking the "else" condition as a possible path even though it
technically couldn't happen ((1) ? xxx : yyy). The suggestion made was
to remove the "?:", but since this only happens in the static analysis
case I used the existing STATIC_ANALYSIS build directive. This change
resolved about 100 false positives.
In doing this, Coverity uncovered a few more uninitialized variables prior
to VIR_FREE calls and a couple of instances where VIR_FREE was being called
on already free'd memory plus one instance where a pointer to free'd memory
was being returned (in qemumonitortestutils.c).
John Ferlan (14):
viralloc: Adjust definition of VIR_FREE() for Coverity
conf: Need to initialize variables before VIR_FREE
virnetserver: Need to initialize 'sigdata'
virnetsockettest: Need to initialize 'path'
virnetdev: Need to initialize 'pciConfigAddr'
commandtest: Need to initialize 'errbuf'
virfile: Need to initialize 'looppath'
lxc: Need to initialize 'dst'
virsh: Need to intialize 'str'
storage: Need to initialize 'zerobuf'
interface: Need to initialize 'ifaces_list'
security: Need to initialize 'sens'
virkeepalive: Remove erroneous VIR_FREE(msg)
tests: Need to initialize 'test' properly on error path
