[libvirt] [PATCH] qemu: forbid large value wraparound in balloon period collection
by Erik Skultety 27 Feb '15

27 Feb '15

We do parse and represent period collection as unsigned int in our internal structures, however commit d5c67e7f4523450023b89b69c16472582c85eeaf converts this to int, thus wrapping around inputs greater than INT_MAX which results in an error from QEMU. This patch adds a check into QEMU driver, because period attribute is only supported by QEMU.

[libvirt] Adding timestamps for all emulator output
by Andrey Korolyov 26 Feb '15

26 Feb '15

Hello, I think it would be useful if libvirt will be able to prefix all messages from emulator pipes with the date stamping, for example I am trying to catch very rare and non-fatal race with virtio-serial-bus: Guest failure in adding device virtio-serial0.0 which is specific to the Windows guests on qemu-kvm. I have supporting infrastructure which can tell me exact times for every action upon this VM, but as bug is not frequent, the continuous monitoring looks like an overkill for a desired goal - find a correlation between emulator event and message from stderr. Patching emulator itself is barely an option, as it is ugly, requires refresh of the running code via loopback migration and completely non-universal, as every hypervisor should be modified seperately. I`d highly appreciate positive consideration for such functionality addition or can write a patch shortly, if needed. Thanks!

[libvirt] [PATCH] util: do not take it as wrong if no PortData is found while getting migrateData
by Zhang Bo 26 Feb '15

26 Feb '15

The function virNetDevOpenvswitchGetMigrateData() uses the cmd ovs-vsctl to get portdata. If no portdata is available, rather than failure in running the cmd, we think we should just print a warning message here, rather than taking it as wrong, because PortData is just optional for an ovs interface. If we take it as wrong anyway, in function qemuMigrationBakeCookie() it will terminate in the middle, and cookies such as NBD would not be baked, further more errors would happen, such as nbd ports get overflowed, etc. Thus, we add an if branch in virNetDevOpenvswitchGetMigrateData() to just warn if portdata is unavailable.

[libvirt] Entering freeze for libvirt-1.2.13
by Daniel Veillard 26 Feb '15

26 Feb '15

As suggested yesterday, and hearing no opposition, I have just tagged Redlease Candidate 1 for libvirt-1.2.13 in git and signed tarballs and rpms for it available at the usual place: ftp://libvirt.org/libvirt/ Based on my own but minimal testing this seems to work, but obviously please give it a try so we can squash bugs and portability issues in time. A candidate release 2 on Thursday and a final 1.2.13 release next Monday is the schedule assumeing no major issue is found, so please give it a test ! Thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
