Yeah, it has something to do with the kernel, glibc, or other such component. qemu-kvm isn't the problem as the error occurs before it is invoked. kernel 3.1.0, glibc 2.14.1 (openSUSE12.1): With libvirt 0.9.7, starting the domain works. This version of libvirt opens control socket with 'socket(AF_INET, SOCK_STREAM, 0)'. With libvirt 0.9.8, the domain does not start. In this version, the control socket is opened with 'socket(AF_PACKET, SOCK_DGRAM, 0)', which fails with EACCES. kernel 3.0.13, glibc 2.11.3 (SLES11 SP2): Regression between libvirt 0.9.7 and 0.9.8 not observed. Initially, I assumed the bug was in glibc. But I can open packet(7) sockets in a test program running as uid=euid=0, just not within libvirtd running with same privileges.
