Hi,
I am trying to figure out how to do p2v and v2v migrations on a Centos 7 kvm
host. With previous versions there was virt-p2v but that does not seem to exist
with Centos-7.
I realize that if I am using shared storage, I can do live migrations but
that does not help with p2v migrations.
Does anyone know what the recommended procedure is for migrating either
physical or virtual machines to Centos-7 is?
While maybe not officially recommended, you could rsync [0] the OS over.
You have a couple of options if you choose to rsync:
1) set up partitions, mount them in a rescue environment, and rsync most everything (certain items from /dev/ can be excluded and everything from /sys/ and /proc/, not to mention NFS mount points, etc). Then tweak fstab, chroot to install grub, and possibly rebuild the initrd/initramfs with proper modules (might need virtio, etc). There are other nuances like MAC addresses on interfaces (if HWADDR is defined in your network-scripts files), but those would be a possible gotcha even if you used Clonezilla.
2) set up partitions, install a fresh copy of CentOS7, then rsync everything over top (means you don't have to sync identical files).
You'll need knowledge of a bunch to do the manual operations (that otherwise would be automated by anaconda) for the rsync method. But the upside is I've managed to keep production boxes up and minimized downtime (maybe slightly more latency/delay on the production host, but it wasn't noticeable).
