A useful table (original posting and explanation of version numbers):
| Rawhide | 1.5.x (currently 1.5.0) |
| Fedora 13 | 1.4.x (currently 1.4.1) |
| Fedora 12 | 1.2.x (currently 1.2.10) |
| EPEL 5 | 1.2.x (currently 1.2.10) |
| RHEL 6.0 | 1.2.7 + backported fixes and features needed for V2V |
| RHEL 6.1 | undecided, probably rebase to latest 1.2.x or 1.4.x |
| RHEL 5.5 with RHEV-M subscription | 1.2.7 + backported fixes and features needed for V2V |

Correct me if I’m wrong, but for people with RHEL but not RHEV-M subscriptions, upgrading to RHEL 6 would mean a downgrade of libguestfs (1.2.10 to 1.2.7), since packages migrated to RHEL get blocked from EPEL?
I didn’t think you could
migrateupgrade between RHEL major versions(?)Ah. I was not thinking of live upgrades, but people choosing to deploy RHEL 6 to replace existing RHEL 5 installations.
