Commits 3c27f3d91e1566854747bbe844186783fc84f3a8 and 1b6f0daa9ae7fcc94e389232d0c397816cda973d added an internal API for running commands asynchronously. It is only used by the copy-in and copy-out APIs. Unfortunately this made the command code very complex: it was almost impossible to redirect stderr to a file, and there were a lot of long-range dependencies through the file. It was also buggy:

This is an experimental (not working) patch which would allow you to set the user and group of the qemu process, assuming the main program is running as root. The reason for this is to allow access as root to disk images which are located on "root-squashed" NFS volumes. This is a particular concern for virt-v2v. The most immediate problem with the patch (which can be fixed easily) is

libvirt doesn't have a concept of "session qemu" for root: https://bugzilla.redhat.com/show_bug.cgi?id=890291 When a libguestfs-using process runs as root, and libvirt runs a qemu subprocess, the qemu subprocess is run as a non-root user (typically qemu.qemu). This causes various problems, for example if we try to open a file which is readable by root but unreadable by qemu.qemu

This is a simple patch which stops nbd_close from waiting too long for a server subprocess to shut down. I wanted to send SIGHUP because the server will be able to catch it and do a clean shutdown if that is required. Is another signal better? Is it right to send a signal here? Rich.

After fuzzing 'qemu-img info' I found that certain files can cause the command to use lots of memory and time. Modify the command mini-library to allow us to place resource limits on subprocesses, and use these to limit the amount of space and time used by 'qemu-img info'. --- configure.ac | 3 +++ src/command.c | 53

I've just built openssh 3.1 for my Redhat 5.1 system (running on a 486 DX-66) using the latest zlib and openssl libraries. Connecting to the machine with ssh seems to work fine (although it takes a while to initiate a connection). But when I transfer a file to the machine with scp, it seems to work fine and the scp completes, but an ssh sub-process remains behind on the client and an sshd

I need ssh-add to fail cleanly if it tries and fails to read a key, rather than prompting the user. I can't seem to figure out how to do that. This is on a Linux 2.6.26 system, running OpenSSH 5.1p1 (as built on debian lenny/sid) First, the things i've tried: * i've unset the DISPLAY and SSH_ASKPASS environment variables, so no X11-style prompting should happen. * i've
