When virDomainGetFSInfo() is called over a QEMU/KVM domain it results into calling of 'guest-get-fsinfo' guest agent command to which it replies with info on guest (mounted) filesystems. When filling return structure we also try to do basic lookup and translate guest agent provided disk address into disk target (as seen in domain XML). This can of course fail - guest can have variety of disks not recorded in domain XML (iSCSI, scsi_debug, NFS to name a few). If that's the case, a debug message is logged and no disk target is added into the return structure. However, due to the way our code is written the caller is led to believe that the target was added into the structure. This may lead to a situation where the array of disk targets (strings) contains NULL. But our RPC structure says the array contains only non-NULL strings. This results in somewhat 'cryptic' (at least to users) error message: error: Unable to get filesystem information error: Unable to encode message payload Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1919783 Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
