[libvirt] libvirtd can not start up
by Lin Qing
Hi all:
I met a issue during boot libvirtd.When I use "libvirtd --daemon
" , libvirtd didn't start up. And I am using the latest libvirt source
code .
Here is the libvirtd.log
/usr/local/var/log/libvirt/libvirtd.log
2012-06-15 06:35:04.230+0000: 16193: info : libvirt version: 0.9.12
2012-06-15 06:35:04.230+0000: 16193: error : virStateInitialize:781 :

2012-06-15 06:35:05.079+0000: 16193: error : daemonRunStateInit:752 :

anybody konws what 's going on ?
Thanks

[libvirt] libvirtd stopped launching
by Zeeshan Ali (Khattak)
Hi everyone,
After I updated my libvirt repo/install from latest git master
yesterday, libvirtd won't just launch for me anymore. The error in log
was:
2012-06-13 11:59:47.427+0000: 30501: error : virStateInitialize:781 :
Initialization of NWFilter state driver failed
2012-06-13 11:59:48.601+0000: 30501: error : daemonRunStateInit:752 :
Driver state initialization failed
Daniel asked me to enable more debug to find the cause and here is the
output: http://static.fi/~zeenix/tmp/libvirt.out
Does anyone know whats going on and how can I fix this? In the
meantime I'll try to see reverting to some older commit helps and if
so, I'll do a git bisect..

[libvirt] [PATCH] docs: Update domain XML schema
by Osier Yang
'boot' tag shouldn't be exclusive with 'kernel', 'initrd', and 'cmdline',
though the boot sequence doesn't make sense when the guest boots from
kernel directly. But it's useful if booting from kernel is to install
a newly guest, even it's not to install a guest, there is no hurt. And
on the other hand, we allow 'boot' and the kernel tags when parsing.

[libvirt] [PATCH] Fix launch of libvirtd when DHCP snooping support is not available.
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
When libpcap is not available, the NWFilter driver provides a
no-op stub for the DHCP snooping initialization. This was
mistakenly returning '-1' instead of '0', so the entire driver
initialization failed

[libvirt] RFC: spice-server default listen behaviour change
by David Jaša
Hi,
I learned few things about ipv6 lately. Most importantly about
dual-socket that means that a process that opens ::0 automatically
listens on both ipv4 _and_ ipv6 unless it sets IPV6_ONLY option of
setsockopt() to 0.
This is pretty important wrt dual-stack configurations because they can
be implemented with just slight changes to spice server (unlike the old
RFE requesting listening on multiple addresses):
* when no addr= or ipvx options are set, listen on ::0
* when ipv4 and no addr= option is set, listen on 0.0.0.0
* when ipv6 is set, set IPV6_ONLY to 1 to make sure that spice server
won't listen on ipv4
* when conflicting ipvx and addr= options are set, error out (this
already works fine)
This will affect upper layers though, given bugs like
https://bugzilla.redhat.com/show_bug.cgi?id=832121 , but it seems to me
like the step in the right direction. Any thoughts/comments before I
file this as a bug?
David

[libvirt] [PATCH 0/3 v5] use qemu's dump-guest-meory when vm uses host device
by Wen Congyang
Currently, we use migrate to dump guest's memory. There is one
restriction in migrate command: the device's status should be
stored in qemu because the device's status should be passed to
target machine.
If we passthrough a host device to guest, the device's status
is stored in the real device. So migrate command will fail.
We usually use dump when guest is panicked. So there is no need
to store device's status in the vmcore.
qemu have a new monitor command dump-guest-memory to dump
guest memory, but it doesn't support async now(it will support
later when the common async API is implemented).
Changes from v4 to v5:
1. address Martin Kletzander's comment
Changes from v3 to v4:
1. allow the user to specify the core file's format
Changes from v2 to v3:
1. qemu supports the fd that is associated with a pipe, socket, or FIFO.
So pass a pipe fd to qemu and O_DIRECT can work now.
Change from v1 to v2:
1. remove the implemention for text mode.
Wen Congyang (3):
qemu: implement qemu's dump-guest-memory
qemu: allow the client to choose the vmcore's format
virsh: allow the user to specify vmcore's format
