Is there any effort to make CIFS-mounting inside guests possible (without
CAP_SYS_ADMIN)?

Even with CAP_SYS_ADMIN I get (cifs-module on host is loaded):

vs01 / # strace mount.cifs //192.168.39.1/home/lmeier /home -o user=lmeier

....
ioctl(3, SNDCTL_TMR_CONTINUE or TCSETSF, {B38400 opost isig icanon echo ...})
= 0
close(3) = 0
munmap(0xb7fb5000, 4096) = 0
mount("//192.168.39.1/home/lmeier", "/home", "cifs",
MS_MANDLOCK, "unc=//192.168.39.1/home\\lmeier,i"...) = -1 ENOMEM (Cannot
allocate memory)
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb7fb5000
write(1, "mount error 12 = Cannot allocate"..., 40mount error 12 = Cannot
allocate memory
) = 40
write(1, "Refer to the mount.cifs(8) manua"..., 60Refer to the mount.cifs(8)
manual page (e.g.man mount.cifs)
) = 60
munmap(0xb7fb5000, 4096) = 0
exit_group(-1) = ?
Process 8701 detached
