From: Martin Peres <martin.peres at labri.fr> This patchset is mostly about fixing fdo bug #66177, reported by Dash Four. This bug is about fan/temp management not working after a suspend/resume cycle. Fan/therm management relies on ptimer's alarm feature to call periodically multiple callbacks that poll the temperature and update the fan speed if needed. The problem is that there is

https://bugzilla.redhat.com/show_bug.cgi?id=847880 https://bugzilla.redhat.com/show_bug.cgi?id=847881 This patch series adds various optional arguments to the tar-in and tar-out commands. Firstly (1/7) an optional "compress" flag is added to select compression. This makes the calls tgz-in/tgz-out/txz-in/txz-out deprecated, and expands the range of compression types available.

With this, I am finally able to get the nbd plugin to do out-of-order responses to the client. Once this series goes in, we should be ready for Rich to cut a release.

We have been inconsistent on how much we reject client-side without even consulting the server, vs. how much we depend on the server to detect failure (even if our request can be deemed undefined per NBD protocol). I'd like to change it so that by default, we reject as much as we can client-side for less traffic, but where the user can also change things on the fly for server-side integration

The first two patches implement the change discussed here: https://www.redhat.com/archives/libguestfs/2016-April/msg00178.html The third patch fixes the mapping of inspection data to OVF VmType which was inherited directly from old virt-v2v and had never been changed. It had a number of problems. The fourth patch is only slightly related to the others. It adds an extra slow test to ensure that

There's more that can be done (in particular, use of CLEANUP_FREE), but this is enough to at least see if I'm on the right track. I couldn't figure out an obvious difference between common/include and common/utils, but it looks like the former is for things that are inlineable via .h only, while the latter is when you need to link in a convenience library, so this landed in the

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.
