[Xen-users] question on migrating disk from current server to HVM
I''m trying to decide the best way to migrate the contents of a disk on a live server to a hardware virtual machine under Xen. The live server has an 83G disk with three partitions: 100M /boot with ext2 2G swap 81G / with ext3 On the Xen server, I have a hardware RAID storage with LVM2 running. I have created a logical volume for the new HVM. Here''s the question: Is there any way to copy the disk contents and/or structure from the live server to the logical volume without having to boot an OS and format the logical volume first? I''ve run a sample dd command on /dev/hda on the live server, piping it through gzip to a spare disk. It compresses down to about 8G. I''m just not sure what to do with it now that I have it. Can I simply uncompress, pipe through dd and send it to the device for the logical volume? Any good examples out there for this? Thanks.
