[libvirt] [v3 0/2] Remove host name checking from iSCSI duplicate source checks
by John Ferlan 13 May '15

13 May '15

Only a v3 because the first two series "Addition host name check for network storage pools" were not well received. If someone wants to pick up/use the the hostname checking code from the v2, then have at it. Patch 1, 2, 7, & 8 use the virSocketAddr code. This series just focuses on the iSCSI duplicate source checks and in particular the removal of the host name checks to be replaced primarily by the duplicate source device path (or IQN) check. For iSCSI devices, checking the resolved host name was not feasible. Instead, if the source device path (IQN) of the new definition is the same as a running pool, then the new definition will be rejected. The secondary check is for an undocumented <inititor> element to define the initiator iqn (see bz 488142). The first patch is "new" - it's something I discovered while doing some extra testing with the v2 of the series. The second patch provides the change and modifies the documentation. It resolves two bz's as listed in the patch description. v2 here: http://www.redhat.com/archives/libvir-list/2015-April/msg01197.html Much discussion took place in v1 though in 7/7: http://www.redhat.com/archives/libvir-list/2015-April/msg00880.html John Ferlan (2): conf: Adjust duplicate source host port check conf: Remove source host name check for iSCSI docs/formatstorage.html.in | 18 ++++++++++++++---- docs/storage.html.in | 8 +++++++- src/conf/storage_conf.c | 7 +++---- 3 files changed, 24 insertions(+), 9 deletions(-) -- 2.1.0

[libvirt] [PATCH] libvirt-guests: Initialize SYNC_TIME
by Michal Privoznik 12 May '15

12 May '15

https://bugzilla.redhat.com/show_bug.cgi?id=1191227 Since 0fa15b19 we have this variable SYNC_TIME which allows users to synchronize time on domain resume. However, despite what documentation says, it's by default on because it's never initialized. Fix this by setting it to zero at the beginning of the libvirt-guests script.

[libvirt] Plans for supporting smbios type 2 ( baseboard/module info ) in libvirt
by Soumik Bhattacharya 12 May '15

12 May '15

Hi Experts, Just wondering if there are plans to implement smbios type 2 parameters in libvirt ? I am trying to pass a couple of critical parameters ( especially 'location' ) to qemu via libvirt but it's failing ( silently ignored ) currently due to libvirt not supporting smbios type 2 ( yet ), even though qemu does support it. Libvirt version used = 1.2.2 Qemu version used = 2.0.0 Thanks & regards, Soumik
