[libvirt-users] SR-IOV Trust Setting
by ]σ§έ Λιαςάη
Is there a setting to allow/disable spoof checking and trust on VF from
SR-IOV device?
Lookin at
https://www.libvirt.org/formatdomain.html#elementsDriverBackendOptions can
this be done through the driver element?
*<driver name='vhost' txmode='iothread' ioeventfd='on' event_idx='off'
queues='5' rx_queue_size='256' tx_queue_size='256'>
<host csum='off' gso='off' tso4='off' tso6='off' ecn='off'
ufo='off' mrg_rxbuf='off'/>
<guest csum='off' tso4='off' tso6='off' ecn='off' ufo='off'/> </driver>*
At the moment i have to manually run:
ip link set $_dev vf $vf spoofchk off
ip link set $_dev vf $vf trust on
Is it possible to set this values from the xml file on a per interface
basis?

[libvirt-users] [OCaml] Reset of the libvirt-ocaml repository
by Pino Toscano
Hi libvirt developers and users,
TL;DR: you need to clone again the libvirt-ocaml repository, if you had
one already
Due to the way the repository was converted from another SCM in the
past, some of the metadata of older commits was broken, and this made
the repository unusable with more strict git configurations (e.g. as
used on GitHub). You can read more details about this in
https://www.redhat.com/archives/libvir-list/2018-September/msg00214.html
The ocaml-libvirt repository from Rich Jones' website was fixed, and
replaced the existing libvirt-ocaml on libvirt.org. The libvirt-ocaml
repository is the official home now (or again) for the OCaml bindings
of libvirt.
This means that you need to clone again the libvirt-ocaml repository,
in case you had already a clone of this repository. In case you had
pending work on it, make sure to carry it over from an old clone to a
newer clone.
As usual, if you have patches for libvirt-ocaml, feel free to send them
to libvir-list, tagging them as [ocaml].

[libvirt-users] how libvirt check qemu domain status?
by Dmitry Melekhov
Hello!
Could you tell me how libvirtd check qemu domain status?
Looks like this is something more then just looking for pid.
Because we have VMs running over gluster storage using gfapi and if
something goes wrong,
then libvirtd became unresponsive often enough..
Thank you!

[libvirt-users] live migration and config
by Dmitry Melekhov
Hello!
After some mistakes yesterday we ( me and my colleague ) think that it
will be wise for libvirt to check config file existence on remote side
and through error if not,
before migrating, otherwise migration will fail and VM fs can be
damaged, because it is sort of remove of power plug...
We missed twice yesterday :-(
Could you tell me is there already such option or any plans to
implement this?
Thank you!

[libvirt-users] Libvirt 4.2.0 hang on destination on live migration cancel
by Scott Sullivan
I'm trying the following command on the source machine:
virsh migrate --live --copy-storage-all --verbose TEST qemu+ssh://
10.30.76.66/system
If I ssh into the destination machine when this command is running, I can
see NBD copying data as expected, and if I wait long enough it completes
and succeeds.
However if I ctrl+c this command above before it completes, it causes virsh
commands (like virsh list) to just hang seemingly forever on the
destination machine.
Here's the libvirt debug entries when I run virsh list in this state:
[root@host ~]# export LIBVIRT_DEBUG=1

(gdb)
This issue I know is fixed in 4.7.0 because I run this version on my CentOS
7 machines and don't have this issue. However on my CentOS 6 machines I
have 4.2.0, and do experience this issue. Upgrading to 4.7.0 on CentOS 6 is
troublesome though, because of the requirement of gnutls >= 3.2.
I'm hoping with the above output someone might be able to point me in the
right direction to a commit that resolved this between 4.2.0 and 4.7.0, or
a possible way to prevent this hang in 4.2.0 as described above ?
Thanks in advance

[libvirt-users] This QEMU doesn't support the LSI 53C895A SCSI controller
by Gionatan Danti
Hi all,
trying to edit a domain xml to enable an LSI SCSI controller I get the
following error:
error: unsupported configuration: This QEMU doesn't support the LSI
53C895A SCSI controller
It is my understanding that the error is raised due to RedHat disabling
this controller in its own qemu-kvm builds. This seems an unfortunate
decision, as it makes harder to migrate from VMWare (which uses LSI SCSI
and SAS adapters) to RH+KVM.
Can anyone elaborate on this decision? It is possible to enable LSI
controller support in RedHat 7.x? Should I open a BZ against it?
Thanks.

[libvirt-users] libvirt reported capabilities doesn't match /proc/cpuinfo while the model does match

Hi,
According to virsh capabilities I only have the following cpu features:

This results on my cpu being detected, if I allow host copy, as AMD chip and
the guest becomes unbearably slow. The model of the host cpu is correct.
I'm using Debian testing/unstable.

[libvirt-users] Libvirt TLS with Short Lived Certificates
by Charles Urquiola
I want to use short lived certificates with libvirtd to provided TLS access
to the daemon. New certificates are generated on a daily basis and
delivered to the host. Does libvirtd re-read TLS certificates with a
reload of the service, systemctl reload libvirtd, or with a SIGHUP or is a
full restart of the daemon required?
