Execute this on your source system. grep MODULES /etc/initramfs-tools/initramfs.conf If it says MODULES=most then you're in luck as it means your initrd contains all kernel modules for all kinds of hardware. And restoring from backup into QEMU-KVM means you only need to reconfigure the bootloader. If it says anything else you'll need to rebuild initrd along with the bootloader configuration. > Is there a way to configure KVM so that it resembles my bare > metal, and the test is significant? That's highly unlikely. On x86-64 there are two QEMU device models worthy of speaking, and that's Intel i440FX and Intel Q35 motherboards. Chances are you have different hardware. So, it *will* have different NIC, Video adapter *and* most importantly, IDE/SATA/SCSI controller. Using Debian and MODULES=most you have a luxury of not to think about it. > I would install a basic debian system in KVM, and then overwrite it > with my backed up files. Is this approach correct? No. Some (but not all) configuration files would differ. Some (but not all) packages would differ. Reco
