[libvirt] [PATCH 0/7] Adjustments for storage/qemu volume/file backing size settings
by John Ferlan
A bit of a mix between fixing some bugs and merging some code between
the block info/stats fetching of backing store data and storage backend
data for volume allocation, capacity, and physical sizes.
Patch 1 just adjusts some comments
Patches 2-3 are code motion
Patch 4 alters how domain/qemu will open the backing store from an open
to a qemuFileOpen and it allows for fetching of more physical sizes (the
code only gets the block backing stores now)
Patch 5 shares the setting of the various size values between storage driver
and domain/qemu
Patch 6 shares the recalculation of the capacity value (it may not be necessary
for patch 5, but I left it there since there's multiple other paths to the
VolTargetInfoFD API).
Patch 7 fixes an issue with displaying the allocation value of a qcow2 backed
file for the GetBlockInfo API (the results will match volume code now).
John Ferlan (7):
qemu: Clean up description for qemuStorageLimitsRefresh
qemu: Add helpers to handle stat data for qemuStorageLimitsRefresh
qemu: Introduce helper qemuDomainStorageUpdatePhysical
util: Introduce virStorageSourceUpdatePhysicalSize
util: Introduce virStorageSourceUpdateBackingSizes
util: Introduce virStorageSourceUpdateCapacity
qemu: Fix GetBlockInfo setting allocation from wr_highest_offset

[libvirt] [PATCH] docs: Format text in <p/> into a block
by Michal Privoznik
With the rework of our webpage I've also noticed that we can make
our <p/> block look more uniform: stretch the lines so that each
has the equal width. Just like if you hit "align to block" in
your favourite text editor.

[libvirt] bug, libvirt, internal error
by CESAR DAVID VASQUEZ ROMERO
Hi, I'm having a problem with libvirt.
Since a few days, when I try to create a virtual machine I get the
following error and I could not solve it
" Imposible completar la instalación: 'internal error: Cannot find suitable
CPU model for given data' "
-------------------------------------------------------------------------------------------------------------
Detalles:

libvirtError: internal error: Cannot find suitable CPU model for given data
-------------------------------------------------------------------------------------------------------------
I tried deleting the / var / cache / libvirt / qemu / capabilities /
directory, and restarting libvirt but it did not work.
I have other virtual machines on the physical server and they work fine,
but I can not create new ones.
How can i fix this
Thank you

[libvirt] [PATCH python] libvirt-override: fix setBlockIoTune failure with flags 3
by xieyingtai＠huawei.com
From: Yingtai Xie <xieyingtai(a)huawei.com>
virDomainGetBlockIoTune() will be called before setBlockIoTune, as a result,
it leads to a failure if set flags with VIR_DOMAIN_AFFECT_LIVE |
VIR_DOMAIN_AFFECT_CONFIG which is an reasonable option.

[libvirt] [PATCH] qemuDomainAttachNetDevice: pass mq and vectors for vhost-user with multiqueue
by gaohaifeng
Two reasons:
1.in none hotplug, we will pass it. We can see from libvirt function
qemuBuildVhostuserCommandLine
2.qemu will use this vetcor num to init msix table. If we don't pass, qemu
will use default value, this will cause VM can only use default value
interrupts at most.
