[libvirt] [PATCH] selinux: Avoid label reservations for type = none during restart
by Shivaprasad G Bhat
The problem is libvirt kills the guests during libvirt restart if more than
guest has security type as none. This is because, libvirt as part of guest-
reconnect tries to reserve the security labels. In case of type=none, the range
of security context happen to be same for several guests. During reservation,
the second attempt to reserve the same range fails and the Guests would be
killed. The fix is to avoid reserving labels for type = none during libvirt
restart.

[libvirt] [RFC] powerpc : Add support for VM in compat mode
by Prerna Saxena
PowerISA allows processors to run VMs in binary compatibility ("compat")
mode supporting an older version of ISA.
Eg,in compatibility mode, a POWER8 host can run a "Power7" VM,conforming
to PowerISA v2.06, while a POWER7 host can run a "POWER6" VM, conforming
to PowerISA v2.05.
QEMU has recently added support to explicitly denote a VM running in
compatibility mode through commit 6d9412ea. Now, a "compat" mode VM can
be run by invoking this qemu commandline on a POWER8 host:
-cpu host,compat=power7
as against the older specification of "-cpu power7".
However, running in compatibility mode is not identical to running
natively on an older processor. Hence the virtualization stack needs to
explicitly provide for a compat-mode VM.
This patch allows libvirt to extend the "fallback" semantics of cpu model to
describe this new mode for PowerKVM guests.
Additionally with the new scheme of things, qemu doesn't provide a way to query
for the supported compat models and models returned when querying with '-cpu ?'
are no longer valid. Hence removing the check cpuModelIsAllowed() for now.
When a user wants to request a power7 vm to run in compatibility mode on
a Power8 host, this can be described in XML as follows :
<cpu mode='custom' match='exact'>
<model fallback='compat'>power7</model>
</cpu>
An alternative approach could be to leave the libvirt XML intact, and merely
change the backend qemu command generation when the VM-requested cpu
does not match the host processor.
Looking forward to suggestions on how this can best be implemented..

[libvirt] [RFC] require for suggestions on support for ivshmem device
by Wangrui (K)
Hi,
Libvirt does not support ivshmem(Inter-VM Shared Memory) device recently,
thus, I would like to know if there's any plan to support it in the future?
If not, I would like to contribute a serial of patches to do so.
On Jan 28, Wangyufei (James) asked about this question, and Daniel replied with 2 suggestions:
1. Libvirt should be capable of configuring the guest's xml on ivshmem.
2.An ivshmem daemon is needed to run on the host to support it, libvirt is recommended to provide such a daemon.
Please refer to https://www.redhat.com/archives/libvir-list/2014-January/msg01335.html for details.
What I'll do later is the 1st suggestion, the 2nd one is left to be accomplished by someone else.
Here is the detailed work I'll do to support configuration of the guest in libvirt:
virDomainDefParseXML: parse ivshmem device xml when defining dom.xml
virDomainDeviceInfoIterateInternal: iterate ivshmem devices
qemuAssignDevicePCISlots: assign ivshmem device pci slots
virDomainDefFormatInternal: format ivshmem device xml (Eg. virsh edit dom)
virDomainDefFree: free ivshmem device def
qemuBuildCommandLine: build ivshmem device command line when vm starts
qemuAssignDeviceAliases: assign ivshmem device aliases when vm starts
virDomainDeviceDefParse: attach and parse ivshmem device xml
qemuDomainAttachDeviceConfig: attach ivshmem device xml persistently
qemuDomainAttachDeviceLive: attach ivshmem device online
qemuDomainDetachDeviceConfig: detach ivshmem device xml persistently
qemuDomainDetachDeviceLive: detach ivshmem device online
There are two ways to use ivshmem with qemu
(please refer to http://qemu.weilnetz.de/qemu-doc.html#pcsys_005fother_005fdevs ):
1.Guests map a POSIX shared memory region into the guest as a PCI device
that enables zero-copy communication to the application level of the guests, The basic syntax is:
qemu-system-i386-device ivshmem, size = <size in format accepted by -m> [, shm = <shm name>]
2.If desired, interrupts can be sent between guest VMs accessing the same shared memory region.
Interrupt support requires using a shared memory server and using a chardev socket to connect to it.
An example syntax when using the shared memory server is:
qemu-system-i386-device ivshmem, size = <size in format accepted by -m> [, chardev = <id>] [, msi = on]
[, ioeventfd = on] [, vectors = n] [, role = peer | master]
qemu-system-i386-chardev socket, path = <path>, id = <id>
The respective xml configuration for the above 2 qemu command lines are shown as below:
Example1: automatically attach device with KVM
<devices>
<ivshmem role='master'>
<memory name='dom-ivshmem' size='2'/>
</ivshmem>
</devices>
NOTE: "size" means ivshmem size in unit MB, "name" means shm name
"role" is optional, it may be set to "master" or "peer", the default one is "master"
Example2: manually attach device with static PCI slot 4 requested
<devices>
<ivshmem role='master'>
<memory name='dom-ivshmem' size='2'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</ivshmem>
</devices>
Example3: automatically attach device with KVM
<devices>
<ivshmem role='master' type='unix'>
<source mode='connect' path='/tmp/ivshmem'/>
<memory name='dom-ivshmem' size='2'/>
</ivshmem>
</devices>
NOTE: "path" means shared memory socket path which is set by the daemon.
" source mode " and "type" is similar with vmchannel.
I'm looking forward to your suggestions, thank you very much.

Speakers will receive a complimentary pass for the event. In the instance
that your submission has multiple presenters, only the primary speaker for a
proposal will receive a complementary event pass. For panel discussions, all
panelists will receive a complimentary event pass.
TECHNICAL TALKS
A good technical talk should not just report on what has happened over
the last year; it should present a concrete problem and how it impacts
the user and/or developer community. Whenever applicable, it should
focus on the work that needs to be done or the difficulties that haven't yet
been solved. Summarizing recent developments is okay but it should
not be more than a small portion of the overall talk.
END-USER TALKS
One of the big challenges as developers is to know what, where and how
people actually use our software. We will reserve a few slots for end
users talking about their deployment challenges and achievements.
If you are using KVM in production you are encouraged submit a speaking
proposal. Simply mark it as an end-user talk. As an end user, this is a
unique opportunity to get your input to developers.
HANDS-ON / BOF SESSIONS
We will reserve some time for people to get together and discuss
strategic decisions as well as other topics that are best solved within
smaller groups. This time can also be used for hands-on hacking
sessions if you have concrete code problems to solve.
These sessions will be announced during the event. If you are interested
in organizing such a session, please add it to the list at
http://www.linux-kvm.org/page/KVM_Forum_2014_BOF
Let people you think might be interested know about it, and encourage
them to add their names to the wiki page as well. Please try to

[libvirt] [PATCH libvirt-tck] bhyve: reconnect to domains after libvirtd restart
by Roman Bogorodskiy
Try to reconnect to the running domains after libvirtd restart. To
achieve that, do:
* Save domain state
- Modify virBhyveProcessStart() to save domain state to the state
dir
- Modify virBhyveProcessStop() to cleanup the pidfile and the state
* Detect if the state information loaded from the driver's state
dir matches the actual state. Consider domain active if:
- PID it points to exist
- Process title of this PID matches the expected one with the
domain name
Otherwise, mark the domain as shut off.
Note: earlier development bhyve versions before FreeBSD 10.0-RELEASE
didn't set proctitle we expect, so the current code will not detect
it. I don't plan adding support for this unless somebody requests
this.

[libvirt] [libvirt-glib] gobject: Fix GEnum generation through glib-mkenums
by Christophe Fergeau
We were only passing libvirt-gobject-domain.h and
libvirt-gobject-connection.h through glib-mkenums, which causes it to
only generate GEnum information for enums found in these headers.
We want to do that for all enums defined in installed headers, so
passing all headers listed in libvirt_gobject_1_0_la_HEADERS is more
appropriate.

[libvirt] libxl: Enable video device selection for Xen
by Stefan Bader
Sorry, this fell complete off my todos for a while. So I split off
the fixup of VRAM into a separate patch which may or may not be used
and only accept vga, xen and cirrus as supported types in the main
patch.
I believe I saw some discussions about how to fix some of the VRAM
values as they are passed into qemu. At least for the Cirrus type
I saw that the command line looked ok but the guest was getting a
much larger VRAM size than it was told.
