[PATCH] libcmpiutil: Fix endianness issues in embedded object parsing
by Viktor Mihajlovski 09 Aug '13

09 Aug '13

From: Thilo Boehm <tboehm(a)linux.vnet.ibm.com> The auxiliary functions _set_int_prop/parse_int_property only worked on little-endian archs as they performed an incorrect reinterpretation of 64bit integers. Fixed by using the proper CMPIValue union fields.

[PATCH] get_dominfo: Use VIR_DOMAIN_XML_SECURE more wisely
by Michal Privoznik 09 Aug '13

09 Aug '13

Currently, even if we are connected RO to the libvirtd, we try to dump domain XML with secure information (VIR_DOMAIN_XML_SECURE flag). This is, however, forbidden in libvirt.

[PATCH V2 0/3] cimtest: Add default network device availability check
by Xu Wang 09 Aug '13

09 Aug '13

The default network device is a constant value. But if it doesn't exist in the system some failure would occur. Hence these patches add checking existence of them. If default network card name exists in the network info list, it will be kept. If not, the value of it will be changed into the 1st available one in the network info list.

[PATCH V2] Add default network card existence checking
by Xu Wang 09 Aug '13

09 Aug '13

The default network card (used as forward device in network pool) name was set as "eth0" in Virt_SettingDefineCapabilities.c. This patch added check if there is such a network card exists in the network info list. If it exists, use it. If not, the default network card would be changed into the first one in the network devices list.

[PATCH 0/2] Add default network card name existence check
by Xu Wang 07 Aug '13

07 Aug '13

Some default name of network cards is set as "eth0", "eth1" or "em1". But when some system doesn't contain such a name, the testcase would fail. Hence these patches added check of default network card and if it doesn't exists in the network info list, the default name would be changed into the first one except "lo". The second patch is updated with default network card check in libvirt-cim.
