whoops, already reported. I did a bad bug search. *** This bug has been marked as a duplicate of bug 499633 *** |
libvirtd is spewing the following incorrect error message at startup in verbose mode: libnuma: Warning: /sys not mounted or invalid. Assuming one node: No such file or directory I did an strace to see what it was doing. It appears it is trying to open a specific file under /sys that doesn't exist. The error message shouldn't say /sys is unmounted as that would lead to incorrect conclusions. Instead, it should say that the specific file under /sys wasn't found and that this likely means it is a single node. I think if we don't fix this, we'll get confused users and complaints. Indeed, I was starting in verbose mode to track down an unrelated startup issue. Indeed, /sys is mounted. Further, node0 does exist. It's only node 1 that does not exist: [root@cct201 init.d]# ls /sys/devices/system/node/node0/cpumap /sys/devices/system/node/node0/cpumap [root@cct201 init.d]# ls /sys/devices/system/node/node1/cpumap ls: cannot access /sys/devices/system/node/node1/cpumap: No such file or directory strace chunk: open("/sys/devices/system/node/node0/cpumap", O_RDONLY) = 9 fstat(9, {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f301e76c000 read(9, "00000000,0000ffff\n"..., 4096) = 18 close(9) = 0 munmap(0x7f301e76c000, 4096) = 0 open("/sys/devices/system/node/node1/cpumap", O_RDONLY) = -1 ENOENT (No such file or directory) write(2, "libnuma: Warning: "..., 18libnuma: Warning: ) = 18 write(2, "/sys not mounted or invalid.
