Re: [libvirt] save/ restore a domain with kvm
Forgot to say: I am working with kvm-72
Does that have implication on the correctness of the save/restore of VM
state ?

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 ?
Check the /var/log/libvirt/qemu/$HOME.log file for more information from
QEMU
