similar to: [PATCH FOR DISCUSSION ONLY] Allow setting of user:group for qemu subprocess.

libvirt doesn't have a concept of "session qemu" for root: https://bugzilla.redhat.com/show_bug.cgi?id=890291 When a libguestfs-using process runs as root, and libvirt runs a qemu subprocess, the qemu subprocess is run as a non-root user (typically qemu.qemu). This causes various problems, for example if we try to open a file which is readable by root but unreadable by qemu.qemu

After fuzzing 'qemu-img info' I found that certain files can cause the command to use lots of memory and time. Modify the command mini-library to allow us to place resource limits on subprocesses, and use these to limit the amount of space and time used by 'qemu-img info'. --- configure.ac | 3 +++ src/command.c | 53

I'm pleased to announce libguestfs 1.32, a library and set of tools for accessing and modifying virtual machine disk images. This release took 6 months of work by many people - see release notes below. You can get libguestfs 1.32 here: Main website: http://libguestfs.org/ Source: http://libguestfs.org/download/1.32-stable/ Fedora 23+:

Wait up to 10 seconds for qemu-nbd to start up and respond to clients. Otherwise the conversion server may attempt to connect before qemu-nbd is ready to serve it. --- p2v/conversion.c | 72 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ p2v/p2v.h | 1 + 2 files changed, 73 insertions(+) diff --git a/p2v/conversion.c b/p2v/conversion.c index cb2deed..1aefcc6 100644 ---

The new ‘-o rhv-upload’ output mode contains a '-' character in the name, but the regular expression which matched the output of the virt-v2v command did not recognize '-' as a valid character. It ended up mapping this to just "rhv" meaning two "rhv" entries would appear in the list of output drivers. Thanks: Ming Xie. --- p2v/ssh.c | 7 +++++--

This attempts to implement the idea proposed in https://www.redhat.com/archives/libguestfs/2010-April/msg00087.html The idea is that an externally managed QEMU (manual, or via libvirt) can boot the appliance kernel/initrd. libguestfs can then be just told of the UNIX domain socket associated with the guest daemon. An example based on guestfish. 1. Step one, find the appliance kernel/initrd

Currently virt-p2v requires Gtk 2. This commit changes virt-p2v so it can be built with either Gtk 2 or 3. By careful use of macros, this code should compile on both recent Gtk 2 and Gtk 3. With no other options, ./configure will now prefer Gtk 3 if it finds it, or fall back to Gtk 2. But you can control this by setting './configure --with-gtk=2|3|check|no' where the options mean: *

This patch is for discussion only. The multiport virtio-console is not accepted upstream, and in any case is currently being rewritten for the nth time. Getting a test environment to test this out is also non-trivial. It look me about a day. You need to compile the alternate qemu (see URL in the patch + attached qemu patch on top of this). You also need to compile the alternate kernel - NOTE:

The bindings are complete, but it needs a great deal more testing. Therefore this is just a preview.
