[PATCH] docs: build: Fix links to 'edit this page' for kbase/manpages/internals
by Peter Krempa 18 Aug '20

18 Aug '20

Commit 862cf2ace4f04dadc175caacc74448e96c625ccb modified the generator to base edit links in the root of the repository but forgot to add the 'docs/' prefix to the code generating kbase articles, manpages and the internals documentation.

[libvirt PATCH] docs: improve auth service listing

Slightly improve the list of known authentication service types: - reword 'ssh' to mention it is used for the ssh driver (for remote QEMU), and stop mentioning the removed Phyp driver - add 'hyperv', used by the HyperV driver - alphabetically sort the list - use a bulletted list instead of a numbered one Signed-off-by: Pino Toscano <ptoscano(a)redhat.com> --- docs/auth.html.in | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/docs/auth.html.in b/docs/auth.html.in index 6f8805b6f5..9964313776 100644 --- a/docs/auth.html.in +++ b/docs/auth.html.in @@ -122,17 +122,19 @@ credentials=defgrp</pre> <p> - The following service types are known to libvirt + The following service types are known to libvirt: </p> - <ol> - <li><code>libvirt</code> - used for connections to a libvirtd - server, which is configured with SASL auth</li> - <li><code>ssh</code> - used for connections to a Phyp server - over SSH, but the Phyp driver has been removed</li> + <ul> <li><code>esx</code> - used for connections to an ESX or VirtualCenter server</li> - </ol> + <li><code>hyperv</code> - used for connections to an HyperV + server</li> + <li><code>libvirt</code> - used for connections to a libvirtd + server, which is configured with SASL auth</li> + <li><code>ssh</code> - used for connections to a remote QEMU driver + over SSH</li> + </ul> <p> Applications using libvirt are free to use this same configuration -- 2.26.2

[PATCH V3 0/3] Xen: Support PCI permissive setting with writeFiltering attribute
by Jim Fehlig 15 Aug '20

15 Aug '20

This is V3 of Marek's series to support the xl.cfg(5) permissive setting on PCI devices. V2 can be found here https://www.redhat.com/archives/libvir-list/2020-April/msg01230.html Changes from V2: Instead of using a permisssive attribute on the <hostdev> element, use a writeFiltering attribute on the <hostdev>'s <source> element. Rational being that the filtering of writes to the PCI config space is done at the source.

[PATCH 0/3] batch: don't require checking retvalue of some bitmap ops
by Nikolay Shirokovskiy 13 Aug '20

13 Aug '20

Most of bitmap setBit/clearBit/getBit users know that the bitmap index is not out of bound and thus don't check the return value. More precisely the stats is next: Method all check =================================== virBitmapSetBit 85 14 virBitmapClearBit 15 3 virBitmapGetBit 15 6 where 'all' is the number of all occurences of the method and 'check' is the number of occurences with 'if (method' pattern. Thus keeping the retvalue checking requirement produces more noise then helps. I guess we even can make these function return void as users can simply compare the index with the bitmap size. The removing of ignore_value was done by sed together with several manual editings where methods calls were splitted across two lines.

[PATCH 1/2] apparmor: allow adding permanent per guest rules
by Christian Ehrhardt 13 Aug '20

13 Aug '20

The design of apparmor in libvirt always had a way to define custom per-guest rules as described in docs/drvqemu.html and [1]. A fix meant to clean the profiles after guest shutdown was a bit overzealous and accidentially removed this important admin feature as well. Therefore reduce the --delete option of virt-aa-helper to only delete the .files that would be re-generated in any case. Users/Admins are always free to clean the profiles themselve if they prefer a clean directory - they will be regenerated as needed. But libvirt should never remove the base profile meant to allow per-guest overrides and thereby break a documented feature.

Plans for the next release
by Jiri Denemark 13 Aug '20

13 Aug '20

I'm sending this quite early this month as I'm on vacation tomorrow and next week and I wanted to make sure the plan for the release is advertised earlier than just a day or two before the freeze. To aim for the release on Sep 01 I suggest entering the freeze in two weeks on Wednesday Aug 26 and tagging RC2 on Friday Aug 28 in the afternoon. I hope this works for everyone. Jirka

[libvirt PATCH] qemu: fix crash in qemuDomainSetBlkioParameters without cgroups
by Pavel Hrdina 12 Aug '20

12 Aug '20

If we don't have cgroups available and user tries to update blkio parameters for running VM it will crash. It should have been protected by the virCgroupHasController() check but it was never called if the API was executed without any flags. We call virDomainObjGetDefs() which sets `def` and `persistentDef` based on the flags and these two variables should be used to figure out if we need to update LIVE, CONFIG or both states.
