[libvirt] libvirt error while start vm with VGA passthrough
by mzawdx wang
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtual...
I have followed the instructions in the RedHat reference
above to the best of my ability to understand them. I add
the pci multi-port serial io card through virt-manager and
it was indeed entered into the virtual machine's
configuration file inside the <devices> tag:
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x07' function='0x0'/>
</hostdev>
However, when I try and start the virtual machine I get
this error:
Error starting domain: internal error Unable to reset PCI
device 0000:00:03.0: no FLR, PM reset or bus reset
available
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py",
line 44, in cb_wrapper
callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/asyncjob.py",
line 65, in tmpcb
callback(*args, **kwargs)
File "/usr/share/virt-manager/virtManager/domain.py",
line 1050, in startup

if ret == -1: raise libvirtError ('virDomainCreate()
failed', dom=self)
libvirtError: internal error Unable to reset PCI device
0000:00:03.0: no FLR, PM reset or bus reset available
The steps I followed were:
1. Check VT-D extensions available and enabled in BIOS - yes
2. Restart virtual host - yes
3. Identify device - yes
<address domain='0x000' bus='0x00' slot='0x03'
function='0x0'/>
4. Add device to virtual machine configuration - yes
. . .
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x07' function='0x0'/>
</hostdev>
<memballoon model='virtio'>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x06' function='0x0'/>
</memballoon>
</devices>
</domain>
5. Start virtual machine - fails
Am I making any obvious errors?

[libvirt] [PATCH] apibuild.py: fix TypeError raised in except clause

When an exception happened inside the try clause in serialize_function,
a new exception was raised in the except clause subsequently:

[libvirt] [PATCH v2 0/7] documentation improvements
by Claudio Bley
Hi.
Version 2 of this series incorporates the following changes:
- patch #1 fail if documentation is missing
- reword subject line of patch #3 as suggessted by Eric
Incidently, patch #1 truthfully makes the build fail because
of missing documentation. Go figure :)
I'll submit a single patch with a fix shortly.
Claudio Bley (7):
docs: abort when missing return or argument documention
docs: only generate function argument info for args with a
description
docs: use div, not table, for notices on opaque types
docs: process code blocks similar to markdown
docs: add class "description" to div's containing descriptions
docs: define style of code blocks inside descriptions
docs: syntax highlight code blocks using SHJS

[libvirt] [PATCH] Enforce return check on virAsprintf() calls
by John Ferlan
Way back when I started making changes for Coverity messages my first set
were to a bunch of CHECKED_RETURN errors. In particular virAsprintf() had
a few callers that Coverity noted didn't check their return (although some
did check if the buffer being printed to was NULL or not).
It was suggested at the time as a further patch an ATTRIBUTE_RETURN_CHECK
should be added to virAsprintf(), see:
https://www.redhat.com/archives/libvir-list/2013-January/msg00120.html
This patch does that and fixes two more instances not found by Coverity
that failed the check.

[libvirt] Libvirt support for windows
by varun bhatnagar
Hi,
I want to use libvirt for windows but when i try to launch virsh it gives
an error message saying "*error: invalid argument in transport methods
unix, ssh and ext are not supported under Windows"*
The version which I downloaded is libvirt-0.8.8.exe. I want to connect to
two virtualization techniques --- *Virtualbox* and *VMWare* If libvirt is
not supported on windows then is there any other tool or API which supports
multiple virtualization technology?
Thanks in advance..!!!!

[libvirt] [PATCH] tests: Don't build securityselinuxlabeltest without qemu

Sources for securityselinuxlabeltest are only defined if qemu driver is

disabled.

Only the first 12 bits should be set in the mask for this range. All
addresses between 172.16.0.0 and 172.31.255.255 are private.
