[libvirt] [PATCH] build: fix build on cygwin
by Eric Blake
Cygwin has getifaddrs(), but not AF_LINK, leading to:
util/virstats.c: In function 'virNetInterfaceStats':
util/virstats.c:138:41: error: 'AF_LINK' undeclared (first use in this function)
if (ifa->ifa_addr->sa_family != AF_LINK)
...
* src/util/virstats.c (virNetInterfaceStats): Only use getifaddrs
if AF_LINK is present.

[libvirt] [PATCH] network: always set disable_ipv6, even when it should be 0
by Laine Stump
libvirt previously only touched an interface's disable_ipv6 setting in
sysfs if it needed to be set to 1, assuming that 0 is the
default. Apparently that isn't always the case though (kernel 3.15.7-1
in Arch Linux reportedly defaults a new interface's disable_ipv6
setting to 1) so this patch explicitly sets it to 0 or 1 as
appropriate.

[libvirt] How to reboot domain(virtual machine) after shutdown it through php-libvirt
by Subhu G
How to reboot domain(virtual machine) after shutdown it through php-libvirt:
Hi,
Am new to php livbvirt. and i successfully listed the all domains in server. and get resource of particular domain and call the shutdown function.
$res = libvirt_domain_lookup_by_name($conn, $name);
$stop = libvirt_domain_shutdown($res);
Now shutdowned domain is not display in domain list.
Now the problem is how to reboot/restart that domain again? libvirt having function for reboot, that is,
libvirt_domain_create($res);
My doubt is what is argument here, how to get that shutdowned domain resources.
Any one kindly help me.

[libvirt] [Query] In search of 'lost' fc_host adapters ?
by Prerna Saxena
Hi,
I recently found that libvirt failed to display Fiber Channel adapters on systems with FC cards.This occured both on x86 as well as powerpc, as follows:
virsh # nodedev-list --cap fc_host
virsh #
The system had legitimate fc_hosts :
[root@localhost ~]# ls /sys/class/fc_host/
host1 host2 host3 host4
[root@localhost ~]#
Debugging further, I found that libvirt has correctly identified the fiber channel host adapters. This could be independently verified by checking capabilities for individual
host adapters. As an example,
[root@localhost ~]# virsh nodedev-dumpxml scsi_host1
<device>
<name>scsi_host1</name>
<path>/sys/devices/pci0000:00/0000:00:00.0/0000:01:00.0/host1</path>
<parent>pci_0000_01_00_0</parent>
<capability type='scsi_host'>
<host>1</host>
<capability type='fc_host'> ===> Fiber channel host.
<wwnn>20000120fa2cf086</wwnn>
<wwpn>10000090fa2cf086</wwpn>
<fabric_wwn>1000000533bedc10</fabric_wwn>
</capability>
<capability type='vport_ops'>
<max_vports>255</max_vports>
<vports>0</vports>
</capability>
</capability>
</device>
However, a virsh query for available fc_host adapters seemed to fail.
I found this was happening because the callbacks pertaining to NodeDevice for the virsh connection pointer were those of "Remote" driver, in place of the "Udev" Node device driver.
The remote driver callback :
static int remoteConnectListAllNodeDevices(virConnectPtr conn,
virNodeDevicePtr **devices,
unsigned int flags)
This didnt seem to process fiber channel host flag, and so my query returned a blank list.
For the problem at hand , it is easy to fix the remote driver to process fc_hosts. But this would unnecessarily duplicate code between udev & remote drivers.
I need some pointers on how callbacks get chosen by libvirt.
The logs show that:
2014-07-31 10:45:43.226+0000: 22913: debug : virRegisterNodeDeviceDriver:619 : registering Test as device driver 0
...
2014-07-31 10:45:43.226+0000: 22913: debug : virRegisterNodeDeviceDriver:619 : registering ESX as device driver 1
...
2014-07-31 10:45:43.226+0000: 22913: debug : virRegisterNodeDeviceDriver:619 : registering remote as device driver 2
...
2014-07-31 10:45:43.228+0000: 22913: debug : virRegisterNodeDeviceDriver:619 : registering udevNodeDeviceDriver as device driver 3
How does libvirt connection register all callbacks for the remote driver, given choice of 4 drivers --test, ESX, remote or Udev ?
Is there a way we can set a preference for the udev driver to be used first -- such that the remote can just be a sane "default" if nothing else is available??
Looking forward to suggestions on how I can fix this ?
BTW, I tried disabling the remote using configure script, but that meant scsi driver (and a few others) got disabled too.
Regards,

[libvirt] [PATCH 0/9] LXC network configuration support
by Cédric Bosdonnat
Hi all,
This patch series aims at filling one of the remaining gaps between lxc and our
lxc driver. It opens up the possibilities to setup IP addresses on network devices,
adds the possibility to add them default gateways, and uses them all in the libvirt
driver. The LXC conf2xml conversion has also been updated to help migrating the
remaining untouched lxc.network.ipv[46]* properties.
The first patch in the series has almost nothing to do with the rest: it just adds
some forgotten VIR_FREE from one of my previous patch.

Cédric Bosdonnat (9):
Domain conf: allow more than one IP address for net devices
LXC: set IP addresses to veth devices in the container
lxc conf2xml: convert IP addresses
Allow network capabilities hostdev to configure IP addresses
lxc conf2xml: convert ip addresses for hostdev NICs
Domain network devices can now have a <gateway> element
lxc conf2xml: convert lxc.network.ipv[46].gateway
LXC: use the new net devices gateway definition
LXC: honour network devices link state
