[libvirt] [PATCH v3 0/3] Add iSCSI hostdev pass-through device
by John Ferlan
Patches 1 & 2 are related to:
Update to http://www.redhat.com/archives/libvir-list/2014-July/msg01098.html
Patch 1/3 is already ACK'd, but felt it was easier to push together.
Patch 2/3 change since last:
- Fix typos as called in review of 8/8
- Adjust the rng file to
- Change the order of things to be <source>, then <auth> to
follow how <disk> (and storage pools) do things. That resulted
in code motion in domain_conf.c and adjustment to the *-iscsi-auth.xml
files
Patch 3 is related to
http://www.redhat.com/archives/libvir-list/2014-July/msg01268.html
John Ferlan (3):
domain_conf: Common routine to handle network storage host xml def
hostdev: Add iSCSI hostdev XML
qemu: Remove extraneous space in function prototypes

[libvirt] File permissions on VNC unix sockets
by Landon Gilbert-Bland
I am using kvm libvirt/qemu, and am trying to get VNC working with unix
sockets. I'm using the following in my XML:
<graphics type='vnc' socket='/tmp/kvmtest'/>
This works, it creates the unix socket and I can use it for VNC. But it
creates the socket with 755 permissions, and owned by libvirt-qemu:kvm.
Ideally, I would like it to be 770 root:libvirtd, but could also work
with 775 libvirt-qemu:kvm.
Basically, I would like the group to be read/write/execute, so that
anyone in this group can use virt-manager (or whatever) to get into the
vm with vnc. I haven't found a way to change this in the settins. It
doesn't seem to be honoring the unix socket settings in
/etc/libvirt/libvirdd.conf (it looks like those are only for
libvirt-sock and libvirt-sock-ro), and I haven't been able to find any
documentation about changing these permissions in the XML.
I can manually chmod/chown the socket after it is created (manually or
with a cron), but that is far from an ideal solution. I don't suppose
anyone has run across a configuration option for this that I have missed?
I have only tested this in ubuntu 14.01 and debian sid, for what it's worth.
Thanks,

[libvirt] [PATCH] virsh: clean up attach-interface paragraph in man page
by Laine Stump
This makes the paragaph about attach-interface more descriptive and
correct, adding in a few bits of information that were previously
missing, e.g. --script is only allowed for bridge interfaces of Xen
domains, target name is regenerated if it starts with vnet, mac
address will be autogenerated if not specified.
(I did this in response to an email asking why a script couldn't be
specified for a bridge interface of a qemu domain, and why an
interface of type='ethernet' couldn't be created with
attach-interface)

[libvirt] Can't run vbox's network driver and storage driver.
by Taowei Luo
Hi, I just can't find a way running the network driver and storage driver
provided by vbox.
When I use vbox:///session as an url to run vbox driver and call network
(or storage) API, the vbox's driver didn't execute. Instead, it would run
drivers in src/network and src/storage.
The problem only comes with the network driver and storage driver. Which
means the vbox's domain driver works well with libvirt.
I know that actually libvirt communicate with vbox driver though the remote
driver, but I don't know how to make remote driver call vbox's network
driver(or storage driver).
BTW, I need vbox's driver because I have to do some test on it.
Thanks,
Taowei

[libvirt] Lifecycle events during reboot for KVM and Xen
by Thomas Bechtold
Hi,
during debugging a problem[1] of Openstack Nova I recognized the following:
Doing a reboot (from inside of the VM with "reboot" command) on a kvm VM
doesn't send any lifecycle events (events debugged with [2]).
Doing the same thing with a xen VM leads to 2 events: First a
VIR_DOMAIN_EVENT_STOPPED and then a VIR_DOMAIN_EVENT_STARTED event.
The problem here is that for the xen case it doesn't seem to be possible
to recognize that a reboot is ongoing. For that reason the OpenStack
Nova component just forces the domain to stop after receiving the
VIR_DOMAIN_EVENT_STOPPED event.
Is it expected that the 2 drivers send different events for the same
action or a bug in qemu/xen/libvirt?
Cheers,
Tom
