[libvirt-users] libvirtd not accepting connections
Hi,
Ever since I recently upgraded to Fedora 25, I can't get kvm working.
It's worked on this system since initial fedora 20 install. All
upgrades were done via yum, then once available, dnf.
I do have libvirt-sock in LISTENING state: STREAM LISTENING
/var/run/libvirt/libvirt-sock
I noticed I also have multiple connections in CONNECTING state:
STREAM CONNECTING 0 /var/run/libvirt/libvirt-sock
STREAM CONNECTING 0 /var/run/libvirt/libvirt-sock
STREAM CONNECTING 0 /var/run/libvirt/libvirt-sock
I rebooted and tried again. Each e.g. 'virsh -c" or virt-manager
command I issue, I end up with another socket in CONNECTING state.
restarting libvirtd.service close them leaving just one LISTENING
strace for virsh -c shows:
4301 socket(AF_UNIX, SOCK_STREAM, 0) = 5
4301 connect(5, {sa_family=AF_UNIX,
sun_path="/var/run/libvirt/libvirt-sock"}, 110) = 0
4301 getsockname(5, {sa_family=AF_UNIX}, [128->2]) = 0
4301 futex(0x7f3c0a2e4fc8, FUTEX_WAKE_PRIVATE, 2147483647) = 0
4301 fcntl(5, F_GETFD) = 0
4301 fcntl(5, F_SETFD, FD_CLOEXEC) = 0
4301 fcntl(5, F_GETFL) = 0x2 (flags O_RDWR)
4301 fcntl(5, F_SETFL, O_RDWR|O_NONBLOCK) = 0
systemctl status libvirtd.service and journalctl -f -u libvirtd.service
do not show any log entries for libvird after it has been started. e.g.
it doesn't log anything about the connection attempts.
Anyone have an idea where to look next?
Thanks,
MikeC

These processes are expected to go away after they reply with all libvirt asks them for. However, it seems like the initialization cannot be completed precisely due to the fact that these processes don't communicate. There might be some details about qemu-system-alpha that are different when compared to, e.g. qemu-system-x86 and libvirt is not (yet) adapted to them, but I installed that emulator and libvirt daemon runs as usual. It looks like a problem in QEMU. Could you, as a workaround, try uninstalling that qemu binary from your system and restarting the service? Also, what versions of libvirt and qemu do you have installed?>Here is gdb output: > >$ sudo gdb -batch -p $(pidof libvirtd) -ex "t a a bt full" > batch.out >[mcc@eastie-fid4-com triage]$ cat
