I've added kvmadm version 0.12.3 to the SFE Omnios and OI-Hipster repositories. Please note that for selected OmniOS Releases you can get kvmadm from the OS-Distro repositories also. I'll try to have always the latest+greates kvmadm version on the repo. If you need kvmadm for an older version of OmniOS (e.g. 151014), then drop me a note.
