Hello all. I'm experiencing a hang while atempting to mount my host machines' file system. I follow the directions explicitly and type mount none /mnt -t hostfs Here is a copy of the stacktrace: Program received signal SIGINT, Interrupt. 0x100ae38d in __sigprocmask (how=0, set=0x50fbbc8c, oset=0x0) at ../sysdeps/unix/sysv/linux/sigprocmask.c:48 48 ../sysdeps/unix/sysv/linux/sigprocmask.c: No such file or directory. (gdb) bt #0 0x100ae38d in __sigprocmask (how=0, set=0x50fbbc8c, oset=0x0) at ../sysdeps/unix/sysv/linux/sigprocmask.c:48 #1 0x100a1cba in change_sig (signal=10, on=0) at process.c:219 #2 0x100a679b in segv_handler (sig=11) at trap_user.c:303 #3 <signal handler called> #4 copy_mount_options (data=0x805a710, where=0x50fbbe80) at /home/vnc/um/linux-um/include/asm/uaccess.h:60 #5 0x10026f5c in sys_mount (dev_name=0x805a6f0 "none", dir_name=0x805a700 "/mnt/local", type=0x805a710 "hostfs", flags=3236757504, data=0x0) at super.c:1428 #6 0x100a46fc in execute_syscall (syscall=21, args=0x50fbbee4) at syscall_kern.c:340 #7 0x100a4b2d in syscall_handler (unused=0) at syscall_user.c:113 #8 <signal handler called> #9 0x100ae3c1 in __kill () (gdb) i sym 268849158 lo_ioctl + 58 in section .text (gdb) i line *268849158 Line 644 of "loop.c" starts at address 0x10065003 <lo_ioctl+55> and ends at 0x10065010 <lo_ioctl+68>. Whats stranger still is using hostfs works fine on my debian 2.2 machine, but on a stock redhat 7.0 machine this hang occurrs. The version of mount (in the virtual machine) is linked with libc-2.1.3, but I also have a version linked with libc-1.9.x that hangs when mounting any file system including one via hostfs. Must the host machine be using a particular kernel version? It is 2.2.16, so I have not as of yet tried the patch mentioned on the download page. Any suggestions? -matt |

Please ignore my earlier message. I upgraded to the newest cvs and now all is well. -matt > Hello all. > > I'm experiencing a hang while atempting to mount my host > machines' file system.
