[libvirt] [PATCHv2] build: fix build on platforms without ptsname_r
by Eric Blake 08 Nov '11

08 Nov '11

MacOS lacks ptsname_r, and gnulib doesn't (yet) provide it. But we can avoid it altogether, by using gnulib openpty() instead. Note that we do _not_ want the pt_chown module; all systems that we currently port to can either properly do openpty() and/or grantpt(), or lack ptys altogether; we are not porting to any system that requires us to deal with the hassle of installing a setuid pt_chown helper just to satisfy gnulib's ability to provide openpty() on even more platforms. * .gnulib: Update to latest, for openpty fixes * bootstrap.conf (gnulib_modules): Add openpty, ttyname_r. (gnulib_tool_option_extras): Exclude pt_chown module. * src/util/util.c (virFileOpenTty): Rewrite in terms of openpty and ttyname_r. * src/util/util.h (virFileOpenTtyAt): Delete dead prototype. --- Alas, this is just complicated enough that I don't feel comfortable pushing it under the build-breaker rule, even though I have verified that it fixes builds on both FreeBSD and Cygwin, as well as still behaves correctly with LXC containers on Linux.

[libvirt] [libvirt-glib 00/24] libvirt-gconfig patches
by Christophe Fergeau 08 Nov '11

08 Nov '11

Hi, Here is a set of patches which start to implement functionality to libvirt-gconfig. The end result is that the "name", "memory" and "features" properties are implemented for the Domain class. Most of the work is about reworking the low-level plumbing to make the implementation as easy as possible. I chose to remove the xmlDocPtr and the xml string that were stored in GVirConfigObject objects and to replace this with a xmlNodePtr. This is useful when creating children objects (eg devices) when parsing a domain XML because the xmlNodePtr will point at the right position in the XML document. One caveat with that approach is that we need to refcount the xmlDocPtr associated with the xmlNodePtr to know when to free it, but this is not implemented yet (though gupnp seems to have code doing exactly this). Then most of the work is adding properties and helpers to make the code easier to write. And thinking about what API we want to expose to clients :) The two test programs should show how the API can be used as it is now. While writing this, I realized we had to do some "useless" work to return strings from libxml2 to glib, ie I g_strdup the string and xmlFree the source so that the caller can free it with g_free. While writing this code, there were at least 2 questions that arose, some input would be welcome :) * I don't know how to handle XMLs where the same node appears multiple times (eg "name"). If it's the latest name that wins, what do we do when changing the name on such an XML document? only modify the last name node? Drop all the redundant name nodes? * I'm also not sure how to make it possible to check whether a given property is set or not. For strings, this is easy, NULL means that the property was not set, but for integers, this is less obvious. Any thoughts on that? Next I'll have to start looking at more complicated properties :) More API questions on the way I guess...

However the guest where I'm running this command has plenty of free memory available: $ free -m total used free shared buffers cached Mem: 5659 872 4787 0 26 351 -/+ buffers/cache: 493 5166 Swap: 1983 0 1983 That's surely easily enough for 1G of RAM + a translation buffer? Anyway, my question is this: Can I somehow get libvirt to strace qemu and put that output somewhere? I tried the strace trick here: https://fedoraproject.org/wiki/How_to_debug_Virtualization_problems#strace but for some reason it doesn't trace into the qemu process. Not sure why, since surely the qemu process is a child of libvirtd?
