Change subject: bootstrap: remove MAC address from vds unique id ...................................................................... bootstrap: remove MAC address from vds unique id CURRENT IMPLEMENTATION vds unique id is at format: @BIOS UUID@_@Low(MAC)@ If BIOS UUID was not available either empty or "Not" were used. PROBLEMS IN CURRENT IMPLEMENTATION BIOS UUID may be missing or duplicate. MAC may change either because of bonding (resolved) or because of physical adapter change. ASSUMPTION Hosts with no BIOS UUID or with duplicate UUID are less than 0.05% of the hosts we manage. CONCLUSION No need to add great complexity malformed UUID hosts 0.05%. But remove the MAC issues from the solution. METHOD Remove the MAC address from vds unique id. Allow to bypass BIOS UUID with configuration. DETAILS If /etc/vdsm/vdsm.id exists at host, content is the vds unique id. If dmidecode -s system-uuid is not '.*Not.*' this is the vds unique id. Else uuidgen > /var/lib/vdsm/host.id and use this as vds unique id. engine will strip '_.*' from vdsm unique id reported by vdsm, to allow communication with older vdsm, and to allow vdsm to continue to communicate with older engines. SIDE EFFECTS If RHEV-H is reinstalled on malformed host (one with no BIOS UUID) it will be treated as a new host. RHEV-H without the complimentary vdsm fix will not be able to register if installed on BIOS that does not support UUID, as it will not generate logical UUID before registration. If BIOS contains duplicate UUID, manual intervention should apply, creating /etc/vdsm/vdsm.id manually. UPGRADE During engine-upgrade all vds unique ids will be stripped out from MAC address. If there are duplicate vds unique ids or empty ids, warn user and list IP addresses of these problematic hosts, suggest host reinstall. Do not allow upgrade to be performed if malformed hosts are not in maintenance mode.
