[PATCH 00/11] Getting it work with SLES / openSUSE
by Cédric Bosdonnat
Hi there!
I know it's been a while since I posted my first version of some patches.
But here I have rebased them on top of Roman's work and added a few other ones.
Cédric Bosdonnat (11):
v2v: also search for windows virtio drivers in symlinks
Update packagelist for SLES
customize: fix windows firstboot script
customize: change windows firstboot path
customize: add support for pvvxsvc
v2v: document SUSE's Xen as a working input hypervisor
v2v: add support for SUSE VMDP drivers
v2v: don't set spice display if QXL isn't supported
appliance: fix errors in init for SLE / openSUSE
v2v: rename RHEL 5 Xen input section into Xen in man
v2v: improve initrd search

[PATCH] launch: Use tsc=reliable.
by Richard W.M. Jones
I've pushed this change already actually.
No one seems to know if this option is safe. If you see strange
timing-related things happening in libguestfs, let us know!

[PATCH 1/2] Revert "appliance: init: run ldconfig"
by Richard W.M. Jones
Running ldconfig adds about 100ms to the boot time. I would prefer
that we understood which libraries need ldconfig to be run, and fix
that. We could also consider running ldconfig in parallel, but since
it might be required by just about any binary that the init script
runs it's not clear what benefit that gives.
This reverts commit 66aa98265dd215dcd4c717e7ef6845fbac859e54.

[PATCH] builder: run/schedule a SELinux relabel if needed
by Pino Toscano
If the guest uses SELinux, then make sure to run a relabel (or at least
schedule one) after the image build: this way the template is
relabelled, or at least it will do that at the next boot, without the
need for the user to ask for a relabel.
This just covers the case of building a new image with no additional
operations on it though.

[PATCH] tools: improve reporting for option errors (RHBZ#1316041)
by Pino Toscano
Improve the error messages produced by C-based tools in case of issues
with the command line options:
- explicitly mention to use -a/-d (and -A/-D in virt-diff)
- when extra arguments are found, mention the correct way to pass
options to certain command line switches (like --format)
- in virt-inspector, give a cleaner error message when neither -i nor
any -m is specified
In all the cases, keep the extra notice to use 'TOOL --help' to get more
help with it.
