[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 …
[View More]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' "
-------------------------------------------------------------------------------------------------------------

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.
