[libvirt] xen:/// vs. xen://FQDN/ vs xen+unix:/// discrepancy
by Philipp Hahn
Hello,
I regularly observe the problem, that depending on the libvirt-URL I get
different information:
root@xen4# virsh -c xen://xen4.domain.name/ list
Id Name State
----------------------------------
root@xen4# virsh -c xen:/// list
Id Name State
----------------------------------
0 Domain-0 running
1 dos4 idle
root@xen4# virsh -c xen+unix:/// list
Id Name State
----------------------------------
root@xen4# xm li
Name ID Mem VCPUs State
Time(s)
Domain-0 0 2044 2 r----- 419.7
dos4 1 4 1 -b---- 33.4
Has somebody observed the same problem and/or can give me any advise on where
to look for the problem?
I'm running a Debian-Lenny based OS with libvirt-0.8.2 on Xen-3.4.3 with a
2.6.32 kernel.
Sincerely
Philipp Hahn

[libvirt] [PATCH] Add XML config switch to enable/disable vhost-net support
by Laine Stump
This patch is in response to
https://bugzilla.redhat.com/show_bug.cgi?id=643050
The existing libvirt support for the vhost-net backend to the virtio
network driver happens automatically - if the vhost-net device is
available, it is always enabled, otherwise the standard userland
virtio backend is used.
This patch makes it possible to force whether or not vhost-net is used
with a bit of XML. Adding a <driver> element to the interface XML, eg:
<interface type="network">
<model type="virtio"/>
<driver name="vhost"/>
will force use of vhost-net (if it's not available, the domain will
fail to start). if driver name="qemu", vhost-net will not be used even
if it is available.
If there is no <driver name='xxx'/> in the config, libvirt will revert
to the pre-existing automatic behavior - use vhost-net if it's
available, and userland backend if vhost-net isn't available.
---
Note that I don't really like the "name='vhost|qemu'" nomenclature,
but am including it here just to get the patches on the list. I could
live with it this way, or with any of the following (anyone have a
strong opinion?) (note that in all cases, nothing specified means "try
to use vhost, but fallback to userland if necessary")
vhost='on|off'
vhost='required|disabled'
mode='vhost|qemu'
mode='kernel|user'
backend='kernel|user'
(So far the strongest opinion has been for the current "name='vhost|qemu'")
Oh, and also - sorry Eric, but I didn't have the brain cells left
tonight to add this new bit to the documentation, and I really want to
get the patch up/in now, so that will have to wait for a followup next
week :-)

[libvirt] [PATCH 1/2] qemu: add -incoming fd:n capability checking
by Eric Blake
* src/qemu/qemu_capabilities.h (QEMUD_CMD_FLAG_MIGRATE_QEMU_FD):
New enum value.
* src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Populate
flags according to qemu version.
* tests/qemuhelptest.c (mymain): Adjust test.
---
I feel a bit dirty relying on just a version test for whether
-incoming fd:n is supported, but it's no different than the
existing code for -incoming unix:path which was added about the
same time. Unfortunately, 'qemu -help' doesn't list which
particular protocols it supports for -incoming.

[libvirt] [PATCH] Add support for multiple serial ports into the Xen driver
by Michal Novotny
Hi,
this is the patch to add support for multiple serial ports to the
libvirt Xen driver. It support both old style (serial = "pty") and
new style (serial = [ "/dev/ttyS0", "/dev/ttyS1" ]) definition and
tests for xml2sexpr, sexpr2xml and xmconfig have been added as well.
Written and tested on RHEL-5 Xen dom0 and working as designed but
the Xen version have to have patch for RHBZ #614004.
Also, this patch is addressing issue described in RHBZ #670789.
Michal

[libvirt] [PATCH 1/2] build-sys: fix build when daemon is disabled by not installing libvirtd.8
by Diego Elio Pettenò
Since the rule to build libvirtd.8 is within the WITH_LIBVIRTD conditional,
so declare the man page in there as well. Without this change, build
without daemon will fail.

[libvirt] draft ~ l10n/i18n
by Zdenek Styblik
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
this is a draft of libvirt l10n/i18n translator's how-to. It is nowhere
definite and it actually is meant ...
It's practically summarized what we've talked about in last couple days.
~~~ DRAFT ~~~
# How-to libvirt l10n/i18n
We are glad you've decided to help with
localization/internationalization of libvirt. Before you do anything
else, stop!
Please, pay attention to following lines to save yourself from eventual
pitfalls.
'.po' files located in this directory are synchronized from Fedora
Project[https://translate.fedoraproject.org/projects/p/libvirt/], thus
it makes little sense to start translating them.
Here are two ways how you can translate and contribute:
## Optimal way
1st step: Create a "Fedora Project" account:
https://admin.fedoraproject.org/accounts/
(New Account, etc)
2nd step: Sign in to the libvirt transifex project
https://translate.fedoraproject.org/projects/p/libvirt/
It uses the just created Fedora Project account
3rd step: "Request to be a translator"
Once you've signed in with step 3, there's a button under the
"Translation files" heading that says something like "Request to
become a translator". Press that.
This is going to take some time.
4th step: Download '.po' file
'.po' file can be downloaded at
https://translate.fedoraproject.org/projects/p/libvirt/
5th step: Translate
See translator's tools section.
6th step: Upload translated file
!!! This point is still a mystery !!!
Upload modified file via web interface.
## Alternate way
If for some reason you don't want to or can't register at Fedora
Project, you still can translate and contribute to libvirt.
1st step: Get '.po' file
Download '.po' file from
https://translate.fedoraproject.org/projects/p/libvirt/ with language
you're going to translate to.
Make a backup copy of it
2nd step: Translate
See translator's tools section.
3rd step: Make a diff
Make a % diff; of the original file and the one you've translated.
eg. % diff -urN lang.po.org lang.po > lang.po.patch;
Send patch file back to mailing-list and somebody from the team
is going to push it at Fedora Project.
Why diff? Because it's easier to validate the work you've done,
solve eventual conflicts etc.
However, this approach has its downsides. First is it brings more
workload to libvirt team, second is '.po' file can change in the
meantime, because you are not able to "lock it" while you're working at
translations.
## Translator's tools
* KAider KDE4 ~ seems to be dead
* gtranslator ~ http://projects.gnome.org/gtranslator/
* poedit ~ http://www.poedit.net/
In case '.po' file in upstream got changed and you need to sync your
current work with upstream, you can try your luck with tool written in
Perl > http://www.zeratul.org/git/?p=scripts/perl/po-sync/.git;a=summary
~~~ DRAFT ~~~
Have a nice weekend,
Z.

[libvirt] fork of php-libvirt
by Lyre
I've added many APIs to php-libvirt, including network, node device,
interface, and snapshot support.
Unfortunately, I wasn't able to contact original author Radek, I really hope
he can see this.
So I forked it, the address is: https://github.com/4179e1/php-libvirt
But there's something undone, as a new php extension writer, I don't know
how the documents are generated. Any clues are appreciated.
BTW, I've pack php-libvirt into rpm via opensuse build service, currently:
it's ready on openSuSE 11.3 & SLES 11 SP1; fedora 14 should works too (it
works on my VM), but the obs environment is not ready yet; and there's
something need to workaround on rhel6. check here:

[libvirt] [PATCH 0/2] fix some bugs in libvirtd
by Wen Congyang
Steps to reproduce this bug:
1. service libvirtd start
2. virsh start <domain>
3. kill -STOP $(cat /var/run/libvirt/qemu/<domain>.pid)
4. service libvirtd restart
5. kill -9 $(cat /var/run/libvirt/qemu/<domain>.pid)
Then libvirtd will core dump or be in deadlock state.
Make sure that json is built into libvirt and the version
of qemu is newer than 0.13.0.
Wen Congyang (2):
avoid vm to be deleted if qemuConnectMonitor failed
avoid closing monitor twice

[libvirt] libvirt 0.8.7 LOCALSTATEDIR ubuntu patch
by Philipp Schmid
Hi,
I'm using ubuntu for our libvirt/kvm host server and needed IPv6 connectivity, so I started to update the latest ubuntu libvirt package (0.8.5) to 0.8.7.
I got all but one ubuntu specific patch to apply. The patch moves the ebiptables script from /tmp to "LOCALSTATEDIR" /lib/libvirt.
I renamed LOCAL_STATE_DIR in the patch below to LOCALSTATEDIR, because this seems to have changed between 0.8.5 and 0.8.7, but I still get the following compile error.
Since this is my first contact with the libvirt source or build system, I would be happy for any pointers on how to fix this and make LOCALSTATEDIR visible to nwfilter/nwfilter_ebiptables_driver.c.
Best regards,
Philipp Schmid
PS: if anyone is interested in working (at least for me with kvm) packages (without the mentioned patch), you can grab them here: http://www.schmidp.com/public/libvirt_0.8.7_ubuntu_natty/
