** Description changed: [Impact] Libvirt spams /var/log/libvirt/libvirtd.log logs with 2014-11-19 14:31:15.787+0000: 46611: warning : qemuOpenVhostNet:493 : Unable to open vhost-net. Opened so far 0, requested 1 2014-11-19 15:18:36.735+0000: 46610: error : virNetSocketReadWire:1377 : End of file while reading data: Input/output error 2014-11-21 20:56:04.275+0000: 46610: error : virNetSocketReadWire:1377 : End of file while reading data: Input/output error 2014-11-23 11:31:34.321+0000: 46610: error : virNetlinkEventCallback:340 : nl_recv returned with error: No buffer space available 2014-11-18 14:47:28.882+0000: 47095: error : qemuMonitorIO:615 : internal error: End of file from monitor [Test Case] 1. Create a precise host 2. Create a number of kvm guests on that host using libvirt. 3. $ sudo killall kvm 4. See errors in log. [Regression Potential] * This is a backport of the upstream fix 89563efc0209b. So there is possibility that I screwed up the backport. However, I think I understand the error cleanup code in this area of libvirt, and have modeled the backport after that cleanup code. * This patch has been tested, and does not appear to adversely affect libvirt functionality other than decreasing the number of warning messages. [Other Info] * This patch does not solve all the warning errors, but it does clean up a significant number of them *(about half given the above test case). This level of libvirt is pretty terrible with spamming it's logs. This level of libvirt also does not have a good interface that does all the reading and writing of the socket, so each function handles the reads and writes directly which results in lots of different error paths. * Upstream commit is available here. http://libvirt.org/git/?p=libvirt.git;a=commit;h=89563efc0209b854d2b2e554423423d7602acdbd + * Trusty and newer already have this fix and many more.
