To use virtio-serial device, unix socket created for chardev with
default umask(022) has insufficient permissions.
e.g.:
-device virtio-serial \
-chardev socket,path=/tmp/foo,server,nowait,id=foo \
-device virtserialport,chardev=foo,name=org.fedoraproject.port.0

#ls -l /tmp/somefile.sock
srwxr-xr-x 1 qemu qemu 0 21. Jul 14:19 /tmp/somefile.sock

Other users in the same group (like real user, test engines, etc)
cannot write to this socket.

These patch series contains a qemu patch and a libvirt patch:
qemu patch: adds a new 'umask' option to -chardev, so that user can
    change the umask.
libvirt patch: pass 'umask=0x002' paramter to qemu command line
    for virtio-serial device

Chunyan Liu (2):
  qemu side: add 'umask' option to chardev
  libvirt side: qemu: add umask(002) to virtio-serial chardev commandline
