[libvirt] [PATCH] Fix deadlock in handling EOF in LXC monitor
by Daniel P. Berrange 26 Sep '12

26 Sep '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> Depending on the scenario in which LXC containers exit, it is possible for the EOF callback of the LXC monitor to deadlock the driver. When the driver calls virLXCMonitorClose, there is really no need for the EOF callback to be invoked in this case, since the caller can easily handle events itself. In changing this, the monitor needs to take a deep copy of the callback list, not merely a reference. Also adds debug statements in various places to aid troubleshooting Signed-off-by: Daniel P.

[libvirt] [PATCH] Change qemuSetSchedularParameters to use AFFECT_CURRENT
by Daniel P. Berrange 26 Sep '12

26 Sep '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> When adding variants of parameter setting APIs which accepted flags, the existing APIs were all adapted internally to pass VIR_DOMAIN_AFFECT_CURRENT to the new API. The QEMU impl qemuSetSchedularParameters was an exception, which instead used VIR_DOMAIN_AFFECT_LIVE. Change this to match other compatibility scenarios, so that calling virDomainSetSchedularParameters(dom, params, nparams); Has the same semantics as virDomainSetSchedularParametersFlags(dom, params, nparams, 0); And virDomainSetSchedularParametersFlags(dom, params, nparams, VIR_DOMAIN_AFFECT_CURRENT); Signed-off-by: Daniel P.
