[libvirt] Memory leak in node_device_conf.c
by Dave Allan
I found what I assume is a memory leak in the node device code while
working on a separate problem; patch attached.

[libvirt] Re: [netcf-devel] Multiple interfaces with identical mac-addresses
by Laine Stump
(expanding Cc to include libvir-list, because this is more of a libvirt
issue)

I think we need to do one of two things:
1) Modify the existing virInterfaceLookupByMACString() api to return a
list of virInterfaces. Although the public API has been in one release,
there has been no functionality behind the API, so there's nobody using
it as it is, and nobody is going to expect to use it as it is either.
Because of that, "backward compatibility" isn't as much of an issue, and
maybe we could let this modification to the API slide.
2) If we want to be really anal, we could modify
virInterfaceLookupByMACString() to return an error if there are multiple
interfaces with that particular MAC address, then provide a new function
(name suggestion?) that would return a list of interfaces.

[libvirt] [PATCH] fix virsh dominfo returns error when virNodeGetSecurityModel() is not supported.
by Tatsuro Enokura
Hi all
I try virsh dominfo in upstream libvirt on xen machine,
the commands returns -1 as follows:
[root@vmi20 ~]# virsh dominfo rhel53rc2_pv_sdb3
Id: 1
Name: rhel53rc2_pv_sdb3
UUID: 05ba9be8-f4e9-e208-11c7-fc936655cd8e
OS Type: linux
State: idle
CPU(s): 2
CPU time: 8.8s
Max memory: 1048576 kB
Used memory: 716800 kB
Autostart: disable
error: this function is not supported by the hypervisor:
virNodeGetSecurityModel
[…
[View More]root@vmi20 ~]# echo $?
1
The explanation of virNodeGetSecurityModel() and
virNodeGetSecurityModel() in libvirt.c is return -2
when hypervisor drivers don't support these operations.
But these functions return -1 in this case, and so
cmdDominfo() in virsh.c returns FALSE.
I make a patch.
- virNodeGetSecurityModel() and virNodeGetSecurityModel()
return -2 when drivers don't supprted these operations.
- In CmdDominfo(), it is no operation when virNodeGetSecurityModel()
and virNodeGetSecurityModel() return -2.

[libvirt] [PATCH] OpenNebula driver changes
by Javier Fontan
Hello,
The first patch makes OpenNebula driver compilable in recent codebase.
The second one adds direct calls to xmlrpc library so it does not
depend on OpenNebula libraries and can be licensed as LGPL.
I have compiled libvirt with the modifications without errors but with
the current version I checked out from git repository I am having
problems:
--8<------
(LD) -o libvirtd libvirtd-event.o libvirtd-qemud.o libvirtd-remote.o
libvirtd-remote_protocol.o
../src/.libs/libvirt_driver_storage.…
[View More]a(storage_backend.o): In function
`virStorageBackendWaitForDevices':
/home/jfontan/git/libvirt.git/src/storage_backend.c:262: undefined

------>8--
Patches are made from 0a29f59e3b8e2c1fb797d2fa93831f21a3e1711e

[libvirt] libvirt support for qemu downscript
by Shahar Klein
Hi
I'm using virsh to launch a VM.
the if-up script works perfectly
but I couldn't find any reference to using down script
I 'gueesed ' and put something like that:
<interface type='ethernet'>
.
.
<script path='ifup'/>
<downscript path='ifdwon'/>
.
.
</interface>
but the down script is not called on shutdown
am I missing something?
thanks

[libvirt] virsh hangs
by Garry Dolley
My system:
Ubuntu Jaunty 9.04
libvirt 0.6.4
kvm 0.8.4
qemu 0.10.0
I'm not sure what triggered this, I was working with several VMs,
and then found that virsh decided to hang:
garry@kvr02:~$ virsh list
Connecting to uri: qemu:///system
<hang>
I have to ^C out of it.
If I 'force-stop' and then 'start' libvirt-bin:
garry@kvr02:~$ sudo /etc/init.d/libvirt-bin force-stop
* Forcefully stopping libvirt management daemon libvirtd
...done.
garry@kvr02:~$ sudo /etc/init.d/libvirt-bin …
[View More]start
* Starting libvirt management daemon libvirtd
...done.
I can then get something:
garry@kvr02:~$ virsh list
Connecting to uri: qemu:///system
Id Name State
----------------------------------
1 vm1 running
4 s3-lax running
14 freebsd-test running
19 freebsd-2 running
<hang>
But it hangs after that 4th one. I must ^C it again.
If I do 'virsh list' again, it'll then show nothing (hangs like it
does above).
Any suggestions?
Thanks

Why don't I use Fedora? Let's not go there... ;)
