[Compass-ci] Re: [PATCH v2 compass-ci] improve multi-qemu code to support queue parameter

+HOSTNAME = opt['hostname_prefix'] || "vm-2p8g.#{ENV['USER']}"

Don't use USER here. Only my-qemu uses USER. Append host system's hostname instead.

+QUEUES = opt['queues'] || "vm-2p8g.#{RUBY_PLATFORM.split('-')[0]}"

vm-2p8g => should base on HOSTNAME instead. Thanks, Fengguang
