[libvirt] [tck PATCH 0/2] set CTRL_IP_LEARNING and DHCPSERVER in filter during no-ip-spoofing test
by Laine Stump 02 Mar '18

02 Mar '18

We've recently discovered two separate bugs that caused libvirt's "DHCP Snooping" feature to not work: https://bugzilla.redhat.com/show_bug.cgi?id=1529338 - libvirt regression https://bugzilla.redhat.com/show_bug.cgi?id=1547237 - libpcap regression Since we didn't have any test suite covering that code, we had the embarrassment of learning of it from someone else's QE (RHV/oVirt QE at Red Hat). This series adds the necessary stuff to the test domain config of libvirt-tck's "no-ip-spoofing" test to exercise the DHCPSnoop thread. (There may be a much better way of dealing with a hash-inside-a-hash; I am an imbecile at perl, and arrived at this code by trial, error, and google searches).

[libvirt] [PATCH 0/3] qemu: Fix updating device with boot order
by Jiri Denemark 28 Feb '18

28 Feb '18

Commit v3.7.0-14-gc57f3fd2f8 prevented adding a <boot order='x'/> element to an inactive domain with global <boot dev='...'/> element. However, as a result of that change updating any device with boot order would fail with 'boot order X is already used by another device', where "another device" is in fact the device which is being updated. To fix this we have to ignore the device which we're about to update when checking for boot order conflicts. https://bugzilla.redhat.com/show_bug.cgi?id=1546971 Jiri Denemark (3): lxc: Drop useless check in live device update Pass oldDev to virDomainDefCompatibleDevice on device update qemu: Fix updating device with boot order src/conf/domain_conf.c | 30 ++++++++++++++++++++++------- src/conf/domain_conf.h | 3 ++- src/lxc/lxc_driver.c | 18 +++++++++--------- src/qemu/qemu_driver.c | 51 ++++++++++++++++++++++++++++++++++++++++---------- 4 files changed, 75 insertions(+), 27 deletions(-) -- 2.16.2

[libvirt] Entering freeze for libvirt 4.1.0 release
by Daniel Veillard 28 Feb '18

28 Feb '18

I didn't sent a warning mail, but people reminded me that it's time to roll the releases, so I just tagged rc1 in git head and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Looks fine with my limited testing, amazingly https://ci.centos.org/view/libvirt/ is all green so things seems they should go smoothly, that said the devil is in the details so please give this RC1 some testing especially on other platforms and OSes ! It all goes well I will push rc2 on Wed and the final release early Fri, but in the meantime, please test it :-) thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH] vshCommandOpt: Do more checking if skipChecks is set
by Michal Privoznik 28 Feb '18

28 Feb '18

Currently if cmd->skipChecks is set (done only from completers) some basic checks are skipped because we're working over partially parsed command. See a26ff63ae4 for more detailed explanation. Anyway, the referenced commit was too aggressive in disabling checks and effectively returned success even in clear case of failure. For instance: # domif-getlink --interface <TAB><TAB> causes virshDomainInterfaceCompleter() to be called, which calls virshDomainGetXML() which eventually calls vshCommandOptStringReq(.., name = "domain"); The --domain argument is required for the command and if not present -1 should be returned to tell the caller the argument was not found. Well, zero is returned meaning the argument was not found but it's not required either.
