Jason, After adding the 1:storage to the log line of the config and restarting the service I do not see anything in the logs. I've started the "virsh pool-list" command several times and there is absolutely nothing in the logs. The command keeps hanging running the strace virsh pool-list shows (the last 50-100 lines or so): ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 getuid() = 0 geteuid() = 0 openat(AT_FDCWD, "/usr/lib/x86_64-linux-gnu/gconv/gconv-modules.cache", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=26376, ...}) = 0 mmap(NULL, 26376, PROT_READ, MAP_SHARED, 3, 0) = 0x7fe979933000 close(3) = 0 futex(0x7fe978505a08, FUTEX_WAKE_PRIVATE, 2147483647) = 0 uname({sysname="Linux", nodename="ais-cloudhost1", ...}) = 0 futex(0x7fe9790bfce0, FUTEX_WAKE_PRIVATE, 2147483647) = 0 socket(AF_INET6, SOCK_DGRAM, IPPROTO_IP) = 3 close(3) = 0 futex(0x7fe9790c0700, FUTEX_WAKE_PRIVATE, 2147483647) = 0 pipe2([3, 4], O_NONBLOCK|O_CLOEXEC) = 0 mmap(NULL, 8392704, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_STACK, -1, 0) = 0x7fe96ca98000 mprotect(0x7fe96ca99000, 8388608, PROT_READ|PROT_WRITE) = 0 clone(child_stack=0x7fe96d297db0, flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SE TTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID, parent_tidptr=0x7fe96d2989d0, tls=0x7fe96d298700, child_tidptr=0x7fe96d2 989d0) = 54218 futex(0x7fe9790bffb8, FUTEX_WAKE_PRIVATE, 2147483647) = 0 futex(0x7fe9790c06f8, FUTEX_WAKE_PRIVATE, 2147483647) = 0 geteuid() = 0 access("/etc/libvirt/libvirt.conf", F_OK) = 0 openat(AT_FDCWD, "/etc/libvirt/libvirt.conf", O_RDONLY) = 5 read(5, "#\n# This can be used to setup UR"..., 8192) = 547 read(5, "", 7645) = 0 close(5) = 0 getuid() = 0 geteuid() = 0 access("/proc/vz", F_OK) = -1 ENOENT (No such file or directory) geteuid() = 0 getuid() = 0 geteuid() = 0 socket(AF_UNIX, SOCK_STREAM, 0) = 5 connect(5, {sa_family=AF_UNIX, sun_path="/var/run/libvirt/libvirt-sock"}, 110) = 0 getsockname(5, {sa_family=AF_UNIX}, [128->2]) = 0 futex(0x7fe9790c0a08, FUTEX_WAKE_PRIVATE, 2147483647) = 0 fcntl(5, F_GETFD) = 0 fcntl(5, F_SETFD, FD_CLOEXEC) = 0 fcntl(5, F_GETFL) = 0x2 (flags O_RDWR) fcntl(5, F_SETFL, O_RDWR|O_NONBLOCK) = 0 futex(0x7fe9790c0908, FUTEX_WAKE_PRIVATE, 2147483647) = 0 pipe2([6, 7], O_CLOEXEC) = 0 write(4, "\0", 1) = 1 futex(0x7fe9790bfb60, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x7fe9790c09d0, FUTEX_WAKE_PRIVATE, 2147483647) = 0 futex(0x7fe9790c0920, FUTEX_WAKE_PRIVATE, 2147483647) = 0 brk(0x5598ffebb000) = 0x5598ffebb000 write(4, "\0", 1) = 1 futex(0x7fe9790bfb60, FUTEX_WAKE_PRIVATE, 1) = 1 rt_sigprocmask(SIG_BLOCK, [PIPE CHLD WINCH], [], 8) = 0 poll([{fd=5, events=POLLOUT}, {fd=6, events=POLLIN}], 2, -1) = 1 ([{fd=5, revents=POLLOUT}]) rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 write(5, "\0\0\0\34 \0\200\206\0\0\0\1\0\0\0B\0\0\0\0\0\0\0\0\0\0\0\0", 28) = 28 rt_sigprocmask(SIG_BLOCK, [PIPE CHLD WINCH], [], 8) = 0 poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}], 2, -1 It get's stuck at the last line and there is nothing happening.
