Thanks to the reminder from Dan Berrange, here's a patch to make build output less verbose, by default. E.g., instead of the redundant multi-line compilation/linking commands, you'll see something like this by default: CC guestfsd-fsck.o CC guestfsd-grep.o CC guestfsd-grub.o CC guestfsd-glob.o CC guestfsd-guestfsd.o CC guestfsd-headtail.o CC

Here is a second version of my patch from last night. It uses the provided ctype function isspace and does the same readdir(). I remove the rosh_issp() function. I admit to being a bit liberal with my use of braces and spaces. We all of the habit of knowing we can invent a more perfect wheel. Let me know if you have any questions.

...llowing operation: regs->eflag |= X86_EFLAGS_TF And return the control from sh_page_fault function by saying "return EFAULT_FIXED". My understanding is that with this flag set when guest completes the execution of the next instruction, it traps to Xen with exit reason TRAP_debug and do_debug handler should be invoked inside x86/traps.c. From there, again I set X86_EFLAGS_TF flag to get guest trapped for next instruction and so on. When i want it to be end I will set X86_EFLAGS_RF flag. However, when I perform above-mentioned procedure I get to see a message "Trace/breakpoint trap...
