[libvirt] PATCH: Switch openvz driver to domain APIs
by Daniel P. Berrange
This patch is the minimum effort port of the OpenVZ driver over to the
new generic domain XML routines. It basically removes all the existing
config format stuff from openvz_conf, defines a set of openvz capabilities
and implements the DumpXML method too. This is enough to get all the core
libvirt functions working. The biggest flaw I see currently is that the
openvz driver doesn't load the existing device config for networks or
filesystems of existing VMs, so you can't see that info in the XML dump

[libvirt] PATCH: Only pass in emulator if user requested it
by Daniel P. Berrange
Previouly with Xen we would only specify an emulator path to XenD if there
was one provided in the XML. With the new domain XML routines we will always
lookup the default emulator path internally using our capabilities data.
So XenD sees an explicit emulator path even if the user didn't request one.
This works fine, except for paravirt guests where you only want to have
the text console active, and not the graphical framebuffer. In this
scenario, XenD starts QEMU-DM to handle the text console, but it crashes
because PVFB isn't configured.
This patch switches us back to the old behaviour where we only pass an
emulator to XenD if the user actually specified one - XenD is intelligent
enough to auto-configure a QEMU instance for paravirt framebuffers as
needed.
The logic looking up the default emulator did live in the generic XML
parsing routines. This patch removes it from the XML parsing stage,
and pushes it down into the individual drivers at time of use (if they
so desire).

[libvirt] remote_protocol.{c,h} ?
by Jun Koi
Hi,
Is it really true that qemud/remote_protocol.{c,h} are created by
rpcgen? If so, why dont we have them created at compile time? I still
see them in the source code.
I modified remote_protocol.x a bit, and when recompiling,
remote_protocol.{c,h} are not reflected at all. So it is expected that
developers must recompile with rpcgen themself??
Thanks,
Jun

[libvirt] [PATCH] Fix vnc port determining for xend
by Cole Robinson
Current libvirt checks xenstore for a xen guests
fixed vnc port on xend > 3.0.3. At least on f8
though, hvm guests don't store the vnc port in
xenstore, it is stored in the sexpr.
Patch fixes the logic to look in the sexpr if
the xenstore lookup appears to fail. This fixes
setting static vnc ports for f8 xen hvm guests.
Thanks,
Cole

[libvirt] [PATCH] Fix capacity reporting for qcow2 images
by Cole Robinson
Libvirt was reporting some ridiculously large 'capacity'
values for some qcow2 images I was creating with relatively
small sizes (200 MB). Seems there was a signedness problem
when parsing the file header. The attached fix shows the
expected values and doesn't look like it will hurt elsewhere.

[libvirt] PATCH: Add a augeas lens for libvirtd.conf
by Daniel P. Berrange
Augeas is a awesome config file manipulation tool. libvirtd has a config
file. libvirtd meet augeas; augeas meet libvirt.
Now instead of telling people
'edit /etc/libvirt/libvirtd.conf and change listen_tls to 1,
and auth_tls to sasl'
we can say run
# augtool <<EOF
set /files/etc/libvirt/libvirtd.conf/listen_tls 1
set /files/etc/libvirt/libvirtd.conf/auth_tls sasl
save
EOF
THis patch is intended to be committed to libvirt, so the config file rules
are distributed alongside libvirt. I'm CC'ing augeas-devel for feedback on
the lens itself.

[libvirt] Bug reported... with respect to console problems
by Stefan de Konink
A few days ago I reported a bug with respect to console problems after the
<bootloader /> bug was 'solved'. Now the status of it did not change, nor
did anyone comment.
Any updates?
