Unless you're lucky, the target volumes won't be in a storage pool, so libvirt will return an error. For libvirtxml we know that the storage is local, so we can inspect it directly. We use qemu-img to determine format and file size. --- lib/Sys/VirtV2V/Connection/LibVirtXMLSource.pm | 48 ++++++++++++++++++++--- 1 files changed, 41 insertions(+), 7 deletions(-) diff --git

Partition number was being passed to guestfs___check_for_filesystem_on based on an index in list_partition. However, this ignores the possibility of multiple block devices. This change makes guestfs___check_for_filesystem_on examine the passed-in device directly to determine if it is a whole device, or what its partition number is. --- src/guestfs-internal.h | 2 +- src/inspect-fs.c | 45

We have tables Users and Communities linked by has_an_belongs_to_many. The join table Communities_Users has additional fields [ is_active, is_blocked, join_date] etc. These are populated using @user.push_with_attributes(:is_active => true,...). Later on how do we update or retrieve the attributes in the link table for a given user or a community with doing it explicitly using SQL? Thanks, Yash -- Posted via http://www.ruby-forum.com/.

This patch refactors the data transfer code with several goals: * Have a common read(source)/write(target) loop so that common processing can happen in the middle of it, e.g. format change/progress bar * Provide volume metadata to transfers to allow smarter reading/writing, e.g. of sparse files * Simplify the data transfer code The patch *isn't* NFC because there are some minor behaviour

...ave some questions for a multi-users utilisation: - Can I change the directory where R is running in order to have a directory per user? Then no problem of erasing R data of an other user. - If it's not possible, can I limite the number of users at the same time? I see "lock", "is_blocked" and "is_started" options in Statistics-R module. How can I use them? Thanks! B??line

Unfortunately libvirt will not always return volume information for a guest's volume. Specifically, it will not return volume information if the volume is not in a storage pool. Rather than displaying a generic libvirt error in this case, advise the user how they can create an appropriate storage pool. Fixes RHBZ#672498 --- lib/Sys/VirtV2V/Connection/LibVirtSource.pm | 27

CD-ROM devices don't necessarily have a <source> element in their libvirt domain XML, which caused an error.

There's a denial of service attack possible from guests on any program that does inspection (eg. virt-inspector, many other virt-* tools, virt-v2v, OpenStack). The attack causes the host process to crash because of a double free. It's probably not exploitable (definitely not on Fedora because of the default memory hardening settings). This patch contains the fix and a reproducer:

If a volume is not an exact multiple of 512 bytes, qemu-img will report its size rounded down to a 512 byte boundary. However, when copying, the file is still read until EOF, which will return more data than was expected. This change prevents that causing a failure in itself. The situation is still not resolved, however, as there are still situations where this will cause a failure. For example,

This picks up python and ocaml. Some of our languages are lacking a number of bindings (for example, lua and perl lack .extents, so I didn't have anything to copy from), and I felt less comfortable with golang and rust. But for python and ocaml, I was able to test a working implementation. Eric Blake (2): python: Implement .list_exports and friends ocaml: Implement .list_exports and

Just spent a little time poking around w/ p2v and am attaching the following pseudo-code for consideration. Note the patches aren't commit ready yet, just looking for thoughts - The first is a fix to get client image building process working on F17. It seems the version of ksflatten there didn't expand the nested %includes which was causing errors (also --interpreter image-minimizer

Figure I'd share the latest revision to p2v I had regarding $subject. The patch now applies against HEAD and compiles fine. I was able to update the package on the client and run virt-p2v, though have yet to do a full end-to-end verification Most likely a little more work is needed to tidy up some edge cases and fully flush things out, but the majority of the work should be in place.
