[libvirt] virDomainShutdown() API failed with error '-1'

Hi Team, We are calling virDomainShutdown() API for shutting the VM. Sometime we see, this API is failing because of 'unknown' reason. It took almost 15 secs to bringdown the VM and at last failed. And the domain goes into shut off state. You can find the time stamp in below log. Could you please let us know in which case this API can fail, how to fix/debug this issue ? We are running 1.0.2 libvirtd version. =========== 20.53.48.532818176: Shuting down domain... 20.54.03.539286528: Failure of libvirt library call: Code: internal error Context: None Message: An error occurred, but the cause is unknown Level: ERROR 20.54.03.539291392: virDomainShutdown() call returned error -1 for CP—3 ============ =========== [host:/var/log/libvirt/qemu]$ virsh list --all Id Name State ---------------------------------------------------- - CP--3 shut off =========== ============ [host:/var/log/libvirt/qemu]$ [host:/var/log/libvirt/qemu]$ libvirtd --version libvirtd (libvirt) 1.0.2 [host:/var/log/libvirt/qemu]$ ============ Regards Ritesh Sharma
