[libvirt] [PATCH] tool/virsh-domain.c: Fix the display of Affinity in function cmdVcpuinfo.
by yangdongsheng 06 Jun '13

(1).Introduce a symbol 'x' to mean the physical cpu on host is offline. (2).And the symbol '-' means the physical cpu on host is online but the affinity of domain for this cpu is not set. There was no diffrence in display between the two kinds of cpu state before this patch, both are '-'.

[libvirt] [PATCHv2] storage: Avoid unnecessary ternary operators and refactor the code

virProcessGetNamespaces() opens files in /proc/XXX/ns/ which will later be passed to setns(). We have to make sure that the file descriptors in the array are in the correct order. Otherwise setns() may fail.
