[libvirt] [PATCH] qemu: fix crash on getting block stats for empty cdrom
by Nikolay Shirokovskiy 13 Apr '17

13 Apr '17

Looks like it was introduced in c5f61513. Before this commit handling empty cdrom was correct becase physical sizes of non block disks are not updated. Now when all types are supported we need to check for empty drives.

Commit 4f4c3b1397c4b5d16af added code to remember errors during freeing of domain objects. This changed the output when testing scaled numbers parsing in virsh-optparse.

[libvirt] question about virtlogd service restart
by Wang King 13 Apr '17

13 Apr '17

Hi all, I found that virtlogd cannot write qemu log and serial log anymore after restart it. It's because of the file descriptor which qemu connected to the virtlogd is broken, and cannot be reconnect after virtlogd restarted. Is this expected behavior or unresolved issue? Thanks Wang King

[libvirt] [PATCH 0/5] Enable CI build testing with Travis
by Daniel P. Berrange 12 Apr '17

12 Apr '17

Since we already sync our repo to github, we can easily take advantage of the free Travis CI system to improve our testing coverage. Our current CentOS CI hardware doesn't have scope for running many more VMs than it already does and even if it did, that imposes an administrative burden to manage the OS. So this uses Travis to get us automated testing of Ubuntu Precise & Trusty, with GCC and CLang, and OS-X with CLang. Daniel P.
