[libvirt] [PATCH v2] xenconfig: fix handling of NULL disk source
by Wim Ten Have
From: Wim ten Have <wim.ten.have(a)oracle.com>
It is possible to crash libvirtd when converting xl native config to
domXML when the xl config contains an empty disk source, e.g. an empty
CDROM. Fix by checking that the disk source is non-NULL before parsing it.

[libvirt] [PATCH v1] xenParseXLDiskSrc: protect against a NULL pointer reference
by Wim Ten Have
From: Wim ten Have <wim.ten.have(a)oracle.com>
This patch protects against a NULL pointer dereference leading to a
SEGV and that way taking out libvirtd while performing domain conversion
requests per domxml-from-native xen-xl xl.cfg within xenParseXLDiskSrc()
when partial disk parameters are provided.

[libvirt] [PATCH] qemu: hotplug: print correct vcpu when validating hot(un)plug config
by Peter Krempa
The error message would contain first vcpu id after the list of vcpus
selected for modification. To print the proper vcpu id remember the
first vcpu selected to be modified.

[libvirt] [PATCH] conf: Don't assign value from ..TypeFromString directly to enum
by Peter Krempa
Enums are unsigned, so it's impossible to check whether the helper
returned -1 for invalid conversions.

[libvirt] libvirt question
by zhunxun＠gmail.com
Hello，I wrote a program using libvirt API to get vm information like this:
/*dom is virDomainPtr type*/
dom=virDomainLookupByID(conn,activeDomains[i]);
if(dom!=NULL)
printf("%d ----------%s\n",activeDomains[i],dom->name);
......
but when compile it,error occured like this:
vm_eraser_detect.c:125:54: error: dereferencing pointer to incomplete type
printf("%d ----------%s\n",activeDomains[i],dom->name);
what is the reason of it???
thanka a lot!

[libvirt] [PATCH] datatypes: removing unnecessary return statement.
by Julio Faracco
There is a wrong 'return' statement after a 'goto' statement inside the
function virConnectCloseCallbackDataRegister(). This commit only removes
the 'return'.
