issue about libvirtd: daemon can not start

[王东亚]

hi,

    I installed kmv on ubuntu-22.04-desktop-amd64, after installing some necessary package (qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst), the libvirtd can not get start, actually, when I running systemctl start libvirtd.service, it'll run a little while (about 3 sec) and then it stops, or should I say it never start. I checked the status, it says  ExecStart=/user/sbin/libvirtd $LIBVIRTD_ARGS (code=dumped, signal=TRAP)
I processed journalctl -p err, it says   ../../../glib/gmem.c:167 failed to allocate xxxxxxx bytes
my laptop has 8G phycial memory
    any suggestion will be appricate. 
    Best Regards.
