[Libvir] virDomainLookupByID problem when Root
Hi all! I've tried to compile and execute info1.c both as user and as root. As user I have no problem, but as root I get: Failed to find Domain 0 I've traced back the problem to the function: virDomainLookupByID(virConnectPtr conn, int id) at the line: path = xs_get_domain_path(conn->xshandle, (unsigned int) id); When root I get path != NULL, otherwise path==NULL; if path==NULL then the block after it is executed and everything is ok, otherwise at the end of the function name=null. (I manually changed path to NULL so that I can run it when root and it works even if info.maxMem it's different from when the program is run as a normal user: it shows -4 instead of 464896). It could be a configuration problem of mine (of Xen Store for example)? Thanks! Chiacchiera con i tuoi amici in tempo reale! http://it.yahoo.com/mail_it/foot/*http://it.messenger.yahoo.com

Make sure you are using the latest version, i.e. libvirt-0.1.3 as 0.1.2 had that problem, which was solved since.

If you use 0.1.3 it won't touch the xenstore backend and use xend access which is preferable, make sure you upgraded and are using the right libraries.

Many thanks for your quick reply!!! I've tried to download the latest version from: http://libvirt.org/sources/ but I couldn't find the 0.1.3 version (tar.gz). Moreover the file: http://libvirt.org/sources/libvirt-cvs-snapshot.tar.gz is the 0.0.6 version (I think). I found the RPMS here: http://download.fedora.redhat.com/pub/fedora/linux/core/development/i386/os/... but when I try to do : yum localinstall libvirt-devel-0.1.3-1.1.i386.rpm libvirt-python-0.1.3-1.1.i386.rpm libvirt-0.1.3-1.1.i386.rpm this is the output: Marking libvirt-python-0.1.3-1.1.i386.rpm as an update to libvirt-python - 0.1.1-1.FC5.i386 Marking libvirt-0.1.3-1.1.i386.rpm as an update to libvirt - 0.1.1-1.FC5.i386 Resolving Dependencies --> Populating transaction set with selected packages. Please wait. ---> Package libvirt-devel.i386 0:0.1.3-1.1 set to be updated ---> Package libvirt.i386 0:0.1.3-1.1 set to be updated ---> Package libvirt-python.i386 0:0.1.3-1.1 set to be updated --> Running transaction check --> Processing Dependency: rtld(GNU_HASH) for package: libvirt --> Processing Dependency: rtld(GNU_HASH) for package: libvirt-python --> Finished Dependency Resolution Error: Missing Dependency: rtld(GNU_HASH) is needed by package libvirt Error: Missing Dependency: rtld(GNU_HASH) is needed by package libvirt-python (same error with rpm -Uvh) Any hint/suggestion? Is it possible to download the 0.1.3 version in the tar.gz format?
