[libvirt] [PATCH 0/7] Adjustments for storage/qemu volume/file backing size settings
by John Ferlan 02 Dec '16

02 Dec '16

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).

[libvirt] [PATCH] docs: Format text in <p/> into a block
by Michal Privoznik 02 Dec '16

02 Dec '16

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] Should Libvirt apply for OSS-Fuzz?
by Michal Privoznik 02 Dec '16

02 Dec '16

Google announced OSS-Fuzz project [1]. It's aim is to test projects with significant user base and/or critical projects to the global infrastructure. I like to think that libvirt falls in both categories :-) You can find a list of already accepted projects here [2]. Once accepted to the project we would have to provide some scripts that build libvirt and run some tests. One of the disadvantages is that we have to provide a docker(!) image where the scripts would run from. What are your thoughts on this? Should we apply?

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: imposible completar la instalación: 'internal error: Cannot find suitable CPU model for given data' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 90, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 2277, in _do_async_install guest.start_install(meter=meter) File "/usr/share/virt-manager/virtinst/guest.py", line 501, in start_install noboot) File "/usr/share/virt-manager/virtinst/guest.py", line 416, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 3606, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) 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 01 Dec '16

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.
