[libvirt] [PATCH] Allows for a <description> tag for domains

by Daniel Veillard

https://bugzilla.redhat.com/show_bug.cgi?id=523639 feature request which makes sense to me, the simple patch attached seems to be sufficient, one can define and have the description back in the dump. Doesn't try to keep the location of the tag, it always get serialized after <uuid>. The only drawbacks I can think of are: - others XML formats may require the same, but honnestly it's trivial - machine generated description (for example if the history log of a domain gets stored there) could grow a lot and I wonder if we have a hard limit on the size when transmitting xml descriptions Oh and I didn't found a good place to test the feature, i.e. no test seems to parse and reserialize XML it's always about conversions.

[libvirt] [PATCH] Avoid a libvirtd crash on broken input 523418

by Daniel Veillard

A simple typo in an XML domain file could lead to a crash, because we called STRPREFIX() on the looked up value without checking it was non-null. Patch is trivial, and should go in but I wonder if we shouldn't make those STR macros safer too like turning #define STRPREFIX(a,b) (strncmp((a),(b),strlen((b))) == 0) into #define STRPREFIX(a,b) ((a) && (b) && (strncmp((a),(b),strlen((b))) == 0)) anyway I think we should apply the patch independently, without it libvirtd crash, with it we get the proper error report: [root@paphio ~]# virsh define RHEL-5.4-64.xml 18:32:21.982: warning : processCallDispatchReply:7570 : Method call error error: Failed to define domain from RHEL-5.4-64.xml error: internal error No <source> 'dev' attribute specified with <interface type='bridge'/> Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
