similar to: Writing policy for guestfsd in libguestfs live

[Stefan asked an interesting question on IRC about how / whether it is possible to use libguestfs remotely. The answer is too detailed for IRC] Consider this model of the libguestfs architecture[i]: (2) libguestfs (3) Linux (1) API protocol syscalls program <--------> libguestfs <--------> qemu <-------->

[Continuing the discussion from: http://lists.gnu.org/archive/html/qemu-devel/2011-01/msg02600.html Sent to libguestfs mailing list] What we are looking at is something like this: guestfish --rw -i LiveGuest [connected read-write to a live guest] ><fs> copy-in files /tmp This is not possible at the moment: it's causes disk corruption to write to disks attached to a live

I've compiled guestfsd and run it on CentOS 6.3. It worked well, but when I quit guestfish, the guestfsd process in guest is always dead itself automatically. Is this a bug? or did I miss something? thanks. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I launched guestfsd in my guest with this command : guestfsd* -rv*. When i close the handle the deamon crashes. This is the output i got (Deamon side) : guestfsd: main_loop : new request, len 0x28 fsync /dev/sda /dev/sr0 : No medium found guestfsd : main_loop : proc 282

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was testing oz/imagefactory on 32 bit arm, you have to have kernel-lpae installed to run kvm. while you can have the regular kernel installed also. You end up having the system booting the regular kernel and you do not get kvm. Ideally supermin will work with the lpae kernel.

Useful for tracking down segfaults in the daemon. This is not upstreamable right now. Example usage: $ ./run guestfish -v -x -a /dev/null run : debug segv "" [...] libguestfs: trace: launch = 0 libguestfs: trace: debug "segv" "" guestfsd: main_loop: new request, len 0x34 Program received signal SIGSEGV, Segmentation fault. debug_segv (subcmd=0x4687050

After this change the debugging output looks like this: guestfsd: enter: mount (0x1) request length 64 bytes commandrvf: stdout=n stderr=y flags=0x0 commandrvf: udevadm --debug settle -E /dev/sda1 calling: settle command: mount '/dev/sda1' '/sysroot//' [ 0.951731] EXT4-fs (sda1): mounting ext2 file system using the ext4 subsystem [ 0.954585] EXT4-fs (sda1):

Dear all, After successfully compiling libguestfs on XEN hypervisor [running ubuntu server 12.04 x64bit] i tried to ./run libguestfs-test-tool but I got this error: guestfsd: /usr/lib/libaugeas.so.0: version `AUGEAS_0.16.0' not found (required by guestfsd) But I have already installed AUGEAS tool.. if I type on terminal for example augtool it works Please check the attached .txt file with

The ELF NEEDED are used to determine guestfsd's library dependencies with help from the dynamic linker and the package manager. This was prompted by Debian bug #972241 which was caused by a libtirpc package renaming in Debian/unstable because the SONAME had been changed. --- appliance/Makefile.am | 26 ++++++++++++++++- appliance/packagelist.in | 62

Sometimes guestfsd fails to gather info, and the virt-<tool> -v output is usually not useful to figure out whats going on within the temporary guest. I see the /init script has support to run guestfsd with a debug tool, which is currently valgrind. Granted, valgrind support is a compile time thing. What would be a good way to optionally run guestfsd with strace or gdb? Should each tool get a

Hi Rich Yes Rich I have tried libguesftfs on powerpc and it was working fine.For some reason i had to format my hard disk and now when I'm again compiling it,I'm getting following error.... Below is the status of configure .. This is how we have configured the optional components for you today: Daemon .............................. yes Appliance ........................... yes QEMU

rpmlint complains that guestfsd has no man page. I think its a good idea to provide one also for guestfsd. Olaf

Goodmornin, Since I am running ubuntu I did " nm -D /usr/lib64/libaugeas.so.0 | grep AUGEAS " and I didn't find "AUGEAS_0.16.0" , but I got this instead : 0000000000000000 A AUGEAS_0.1.0 0000000000000000 A AUGEAS_0.10.0 0000000000000000 A AUGEAS_0.11.0 0000000000000000 A AUGEAS_0.12.0 0000000000000000 A AUGEAS_0.14.0 0000000000000000 A AUGEAS_0.15.0 0000000000000000 A

daemon.c does just a chroot, without chdir. The result is that pwd does not work correctly (it causes fs/dcache.c:prepend_unreachable() to add the unreachable string).
