[libvirt] [PATCH] usb: Correct test for virUSBDeviceListSteal
by Gonglei (Arei)
In the for loop, the if condition is always true, and will execute memmove.
But it will cause the list->devs[i+1] overflow while i equals list->count-1.

[libvirt] [PATCH glib] Fix name of gvir_config_domain_chardev_source_pty_set_path
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The method gvir_config_domain_chardev_source_pty_set_path was
accidentally called gvir_config_domain_source_pty_set_path.
This naming flaw in turn caused the introspection data to
be incorrectly generated, putting a 'source_pty_set_path'
method on the GVirConfigDomain object.

[libvirt] virsh live migration w/o shared storage fails with error as vm is not running
by chandrashekar shastri
Hi All,
We are testing the upstream KVM with :
Kernel, Qemu, Libvirt, Virt-Manager is built from the source (git).
kernel version : 3.9.0+
qemu version : QEMU emulator version 1.5.0
libvirt version : 1.0.5
virt-install : 0.600.3
I have followed the below steps to test the "Live migration w/o shared
storage" feature :
1. Created the qemu-img create -f qcow2 vm.qcow2 12G on the destination
host which is same as the source.
2. Started the guest on the source
3. Started the vncdisplay to monitor the guest
4. Initiated the migration "virsh migrate --live rhel64-64
qemu+ssh://9.126.89.202/system --verbose --copy-storage-all"
5. It started the copying the storage from souce to destination
(conitinously monitored it was growing)
6. Guest on the destination was paused and was running on the source
7. At some point the VM on the source shutdown and got an error on the
vnc display as " Viewport: write: Broken pipe (32)" and the VM on the
destination was undefined.
Below is the libvirt debug log, please let me with your comments.
Debug log:

[libvirt] [PATCH 0/4] libxl: implement some chuncks of the NUMA interface
by Dario Faggioli
Hi Jim, Everyone,
First patch series, so maybe a small introduction is required: I'm Dario and I
work for Citrix on improving the NUMA support of Xen.
This patch series implements some of the missing bits and pieces, in the libxl
driver, regarding obtaining per-host and per-domain NUMA related information.
It's not the full libvirt NUMA interface, since we don't have all we would need
for that in Xen yet (we will in the next version, 4.4), but it's certainly
better than having nothing! :-)
Basically, I'm enhancing capability reporting, to cover NUMA topology (patch
01), and I'm implementing nodeGetCellsFreeMemory (patch 02) and
virDomainGetNumaParameters (patch 04) for the libxl driver. This last one
requires at least Xen 4.3, so I put the implementation within the proper
#ifdef-ery.
What I'm really not sure about is patch 03, which is something I need if I want
patch 04 to function properly. Basically it is about advertising that the libxl
driver supports VIR_TYPED_PARAM_STRING. I looked at how that is done in the
qemu driver, but I'm not entirely sure I completely understood the logic behind
it, so, please, tell me if I missed or misinterpreted anything! In particular,
should I have added more of those "flags &= ~VIR_TYPED_PARAM_STRING_OKAY;"
statements, as it happens in the qemu driver? If yes, in which functions?
Finally, allow me to say that it was a while that I wanted start hacking a bit
on libvirt. I'm really glad I've eventually been able to do so, and I
definitely plan to continue (with particular focus on NUMA related stuff).
Comments are of course more than welcome. :-)
Thanks and Regards,
Dario

[libvirt] [PATCH] conf: don't check hyperv spinlock retries if disabled
by Ján Tomko
<hyperv>
<spinlocks state='off'/>
</hyperv>
results in:
error: XML error: missing HyperV spinlock retry count
Don't require retries when state is off and use virXPathUInt
instead of virXPathString to simplify parsing.

[libvirt] [PATCH] Fix build with clang
by Ján Tomko
Partially revert cdd703f's revert of c163410, as linking with clang
with --param=ssp-buffer-size=4 still fails with:
"argument unused during compilation".
---
This is technically a build-breaker fix, but I haven't pushed it yet,
to prevent reverting a revert of a revert.

[libvirt] best way to provide disk storage for vm without shared storage system
by Vasiliy Tolstov
Hello. I'm very happy with libvirt and qemu, that great software!
(after some playing i want to create golang bindings to libvirt)..
Now i provide ext4 fs for qcow2 images (raid1 with two sata disks).
Now i don't need live migration (but may need it in feature).
What is the best way to provide disks to vm in case of performance,
ability to create backups (i don't want lvm snapshots)?
As i search from google more speed can take physical storage - lvm.
But may be QED or FVD can provide near lvm performance to me?
