Restore vm

Asked by YG Kumar

Hi,

We have an openstack platform with KVM as hypervisor. Due to some reason we lost VMs due to hardware issue with the physical disks. But we have the VM's disk files still present. But we lost the 'base' backing files. We want to restore the data present in those disk files. Is it possible ? if so how ?

Thanks
Kumar

Well firstly I'd start backing up the backing files... Why did you miss those out???

If you make a new VM can you not use existing disks and recreate the servers that way? This will make the file that ties them together.

You could also make a dummy server with new disks then read the configuration file and make a copy but use the files you already have to make servers.

Since the left over disk has data but no the boot files, how to make it bootable ? Any idea ?

Unfortunately those inks didn't actually mention how to make my vm up and running. I simply want to know how to make my left over disk files with data , combine with boot files so that it would boot without any issue.

Thanks
