Here is the /var/log/libvirt/qemu/vm_dubi2.log file. It shows a trailing '-incoming stdio' which is rejected by QEMU, The rest is correct and is probably the translation of the XML. The XML as appears in the saved file vm_dubi2.sav (also below) looks fine . But that file has some prefix binary section which I do not know its content Again , the saved VM state file is : thanks Zvi Dubitzky Virtualization and System Architecture Email:dubi@il.ibm.com IBM Haifa Research Laboratory Phone: +972-4-8296182 Haifa, 31905, ISRAEL "Daniel P.

I am working with virsh
The version of VIRSH as it shows is : virsh # version Compiled against library: libvir 0.4.4 Using library: libvir 0.4.4 Using API: QEMU 0.4.4 Running hypervisor: QEMU 0.9.1
Under virsh I do the following : 1. suspend a running VM 2. save it to a file with the 'save' command 3. restore the saved domain file with the 'restore' command while the domain is still in the suspend mode or after it was shutdown/destroyed (not seen with 'list --all) In either case I get the error message saying :
virsh # restore /home/dubi/xml/vm_dubi2.sav libvir: QEMU error : operation failed: failed to start VM error: Failed to restore domain from /home/dubi/xml/vm_dubi2.xml
Any idea what is the failure reason ?
