Created attachment 1579638 [details] libvirtd log Description of problem: libvirtd crashed when start vm with emulatorpin configuration Version-Release number of selected component: libvirt-4.5.0-21.virtcov.el7.x86_64 How reproducible: 100% Steps to Reproduce: 0. The host has 4 cpus online: # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 ... 1. Prepare a vm xml with emulatorpin configuration: ... <vcpu placement='static' cpuset='0-3' current='8'>16</vcpu> <cputune> <emulatorpin cpuset='3'/> </cputune> ... 2. Create vm: # virsh create min-rep.xml error: Disconnected from qemu:///system due to end of file error: Failed to create domain from min-rep.xml error: End of file while reading data: Input/output error 3.
