[libvirt] [PATCH] wireshark: Adapt to dissector function header change
by Michal Privoznik 28 Jul '16

28 Jul '16

In wireshark commit bbdd89b9 (contained in 2.1.0 release) they have changed prototype of dissector function. Now it returns number of bytes consumed by the dissector, and can get a pointer to user specified data (which we don't use).

[libvirt] [PATCH 0/2] tools: Fix usage of incorrect environment variables
by Erik Skultety 28 Jul '16

28 Jul '16

According to https://bugzilla.redhat.com/show_bug.cgi?id=1357363, most of virt-admin's environment variables are not taken into effect when set. As it turned out, virsh suffers from the very same problem which resides in the generic vsh.c module.

[libvirt] logging: Libvirtd could not create its own logfile, when the path /var/log/libvirt is not exist.
by weifuqiang 28 Jul '16

28 Jul '16

Hi all: Libvirtd could not create its own logfile, such as /var/log/libvirt/libvirtd.log, when the path /var/log/libvirt is not exist. It may be a problem,I think,so try to make patch when open file failed in virLogAddOutputToFile. or any better idea? ------------ Libvirtd just creates its logfile, such as /var/log/libvirt/libvirtd.log, DURING INSTALLATION. If the logfile(we mean its path here,that's /var/log/libvirt/) is deleted during its runtime, even if we restart libvirtd, such file would not be generated automatically, thus, the logs are all missing after then, it becomes impossible to debug problems after then as well. So, we try to mkdir the deleted path after restarting libvirtd. Or, any better idea? Thanks in advance. Wei Fuqiang

[libvirt] [libvirt RFC PATCH 00/10] Add support for qemu's JSON pseudo'protocol for backing store
by Peter Krempa 27 Jul '16

27 Jul '16

Libvirt didn't handle this for a long time and VMs with such config would not start we should implement it. Using JSON is basically the only option to specify advanced configuration for a backing file. Field names were taken from qemu's source since there isn't really documentation for this.
