Comment 1 Andy Burns 2007-04-01 22:59:26 UTC
Running virt-manager again I notice that it displays a red warning triangle with
the message that "The host CPUs do support virtualization, but it it isn't
enabled in the BIOS"

Originally virtualuzation /was/ disabled in BIOS, but now it /is/ enabled, just
about to power-cycle machine to make sure.

Comment 2 Andy Burns 2007-04-01 23:22:40 UTC
It seems the host machine needs a power-cycle, rather than just rebooting after
exiting BIOS setup for the virtualization change to take effect, sorry for the
