[ovirt-users] Problem with hosted engine setup - vsdmd does not start

[Will Dennis]

I believe sudo is NOT setup for passwordless (then again, didn't see that in any pre-req instructions...) Who would be the sudoer in this case?

read(9, "sudo: a password is required\n", 4096) = 29

Could it be that sudo is not configured to operate passwordless?

The strat-up can then fail, because sudo requires a ty, but this isn't available during service start.
