hi all, i am exploring openstack. By the openstack i experimented the resizing instance its working fine. But from virsh i tried save and redstore VM its not working properly. i put GDB on libvirtd process also its not showing anything. its running perfectly. while virsh save vm id filename -> saving the VM and get into shutdown state. then i tried to restore by virsh restore filename --running -> its showing as running then its getting destroyed automatically. I cant able find the issue. I grepped the logs also its not showing anything related to errors. 2. By virsh save-image-edit filename i tried to edit the vCPUs number but i am not able to edit and save the file. Its showing the following error -> "error: unsupported configuration: Target domain vCPU count 2 does not match source 1" Give some suggestions to resolve the issue. Thanks & regrads, cooldharma06 .. :)
