[Libvir] PATCH: Force close of virConnectPtr if client quits abnormally
by Daniel P. Berrange
If a remote client quits abnormally (or if the server forcably drops a
client for misbehaviing), it is possible that the virConnectPtr object
is not closed. This leads to a build up of active connections in the
server. The attached patch simply calls virConnectClose when killing off
a client connection if there is a non-NULL client->conn object.
Dan.

[Libvir] [PATCH] Add the check of the device source
by Masayuki Sunou
Hi
If specified device source does not exist,
Not appropriate error is displayed.
----------------------------------------------------------------------
# virsh attach-disk PV_FC7_14 NOT_EXIST_PATH xvdd
libvir: Xen Daemon error : POST operation failed: (xend.err 'Device
51760 (vbd) could not be connected. Hotplug scripts not working.')
----------------------------------------------------------------------
This patch checks the existence of the device source path,
and correct message is displayed in case of error.

[Libvir] [PATCH] If ./configure --enable-debug=yes, print libvirt calls
by Richard W.M. Jones
This can prove useful if we want to track down problems like the
double-call of domainSuspend.
Also attached below is the output of virt-manager when this tracing is
enabled.
Note that if --enable-debug is not set, then no extra code is added to
libvirt.
Rich.

[Libvir] Double call to domainSuspend callback
by Bruce.Evans＠Sun.COM
Hi,
I have implemented the 'domainSuspend' callback in
libvirt for my hypervisor (see test.c or qemu_internal.c for reference)
When using the Red Hat Virtual Manager (after connecting
to my hypervisor), clicking on a domain row,
then clicking the 'open' button at the botton right of the
window, I get a new window where I can click the 'Pause'
button for instance.
When I do this, the 'domainSuspend' callback is entered
twice as shown in my debug code below.
Why is this happening? Is it a bug?
So somewhere in the RHVM python code, this call is
getting activated twice.
Thanks,
-Bruce

The next version of virt-install will support this explicitly. I am
reliably assured that it should work in qemu & Xen.
Support is not there yet in virt-manager.

This is a bug. Do you know what version of libvirt & virt-manager this
happens with? Suspend _ought_ to work with QEMU with libvirt >= 0.2.0.

I haven't played with live CDs & virt-manager at all, but I'll have a
go. What live CD were you trying?

This is another bug. If you get me the version of virt-manager, I'll
look into it.

[Libvir] Howto: install libvirt on Debian Etch (the ugly way)
by Roman Ammann
Hello list
I read on the list that other people tried to install libvirt on Debian
Etch. I finally succeeded so I'll post a little Howto. Maybe someone
with a better understanding of automake and C stuff knows a nicer way
but the ugly folder with the links to the different header files.
The start point is a Debian Etch with a running Xen (in my case it's the
xen-hypervisor-3.0.3-1-i386-pae package). If you're not using the PAE
version of the xen-hypervisor change the "apt-get source" line
accordingly.
First you will need to install a bunch of development packages
apt-get install build-essential libxml2-dev libncurses5-dev
apt-get isntall libreadline5-dev python-dev
Go to your home directory and install the Xen hypervisor sources
cd
apt-get source xen-hypervisor-3.0.3-1-i386-pae
Create a folder with a bunch of symbolic links. We will use this folder
libvirt to find the header files.
mkdir libvirt-include
cd libvirt-include/
ln -s /root/xen-3.0-3.0.3-0/xen/include/public/xen.h
ln -s /root/xen-3.0-3.0.3-0/tools/xenstore/xs.h
ln -s /root/xen-3.0-3.0.3-0/tools/xenstore/xs_lib.h
ln -s /root/xen-3.0-3.0.3-0/xen/include/public xen
ln -s /root/xen-3.0-3.0.3-0/linux-2.6-xen-sparse/include/xen/public/ xen/linux
Configure the dynamic linker that it will be able to find the libxenstore library
echo '/usr/lib/xen-3.0.3-1/lib' > /etc/ld.so.conf.d/i486-linux-gnu.conf
ldconfig
Go to your home directory, download an extract the libvirt source package
cd
wget http://libvirt.org/sources/libvirt-0.2.3.tar.gz
tar xvfz libvirt-0.2.3.tar.gz
cd libvirt-0.2.3
Configure, build and install the libvirt
CFLAGS="-fno-stack-protector -I/root/libvirt-include -L/usr/lib/xen-3.0.3-1/lib" ./configure --with-xen --without-qemu
make
make install
Enable the Unix socket server for xend. Edit /etc/xen/xend-config.sxp and change the line
#(xend-unix-server no)
to
(xend-unix-server yes)
Restart your Xen-Daemon
/etc/init.d/xend restart
If everything work you should see your running virtual machines when you enter
virsh list

[Libvir] Release of libvirt-0.3.0
by Daniel Veillard
Considering the amount of changes available in CVS, a release was in
order plus increasing the minor release number was also making sense.
The package is available at
ftp://libvirt.org/libvirt/
The main change is the secure remote support at the API level thanks to
Richard Jones, look at the specific page to get informations on what
is available and how to set up the certificates needed for authentication:
http://libvirt.org/remote.html
it's worth also looking at the URI documentation to see how to build the
connection URI strings
http://libvirt.org/uri.html
Last thing, the background daemon has been renamed between versions 0.2.3
and the current version from libvirt_qemud to libvirtd since it now also serve
for the remote support, so when upgrading the package it's a good idea
to stop first the libvirt service, do the upgrade and then restart the service
otherwise you may end up with a old version of the daemon running.
This release includes a lot of changes:
+ Secure Remote support (Richard Jones).
See the remote page of the documentation
+ Documentation:
- remote support (Richard Jones)
- description of the URI connection strings (Richard Jones)
- update of virsh man page
- matrix of libvirt API/hypervisor support with version
informations (Richard Jones)
+ Bug fixes:
- examples Makefile.am generation (Richard Jones)
- SetMem fix (Mark Johnson)
- URI handling and ordering of drivers (Daniel Berrange)
- fix virsh help without hypervisor (Richard Jones)
- id marshalling fix (Daniel Berrange)
- fix virConnectGetMaxVcpus on remote (Richard Jones)
- avoid a realloc leak (Jim Meyering)
- scheduler parameters handling for Xen (Richard Jones)
- various early remote bug fixes (Richard Jones)
- remove virsh leaks of domains references (Masayuki Sunou)
- configCache refill bug (Richard Jones)
- fix XML serialization bugs
+ Improvements:
- QEmu switch to XDR-based protocol (Dan Berrange)
- device attach/detach commands (Masayuki Sunou)
- OCaml bindings (Richard Jones)
- new entry points virDomainGetConnect and virNetworkGetConnect
useful for bindings (Richard Jones)
- reunitifaction of remote and qemu daemon under a single libvirtd with
a config file (Daniel Berrange)
+ Cleanups:
- parsing of connection URIs (Richard Jones)
- messages from virsh (Saori Fukuta)
- Coverage files (Daniel Berrange)
- Solaris fixes (Mark Johnson)
- avoid [r]index calls (Richard Jones)
- release information in Xen backend
- virsh cpupin command cleanups (Masayuki Sunou)
- xen:/// suppport as standard Xen URI (Richard Jones and Daniel Berrange)
- improve driver selection/decline mechanism (Richard Jones)
- error reporting on XML dump (Richard Jones)
- Remove unused virDomainKernel structure (Richard Jones)
- daemon event loop event handling (Daniel Berrange)
- various unifications cleanup in the daemon merging (Daniel Berrange)
- internal file and timer monitoring API (Daniel Berrange)
- remove libsysfs dependancy
- call brctl program directly (Daniel Berrange)
- virBuffer functions cleanups (Richard Jones)
- make init script LSB compliant
- error handling on lookup functions (Richard Jones)
- remove internal virGetDomainByID (Richard Jones)
- revamp of xen subdrivers interfaces (Richard Jones)
+ Localization updates
Thanks to everybody who helped for this release, with code, bug reports
or suggestions !
Daniel
