Bug #13779
Updated by Dominic Cleal about 8 years ago
For EC2 provisioning, setting the compute profile on a new host causes a default AMI to be set that differs from the AMI set in the image associated with the compute resource. Steps to reproduce: 1) add a new AWS EC2 compute resource 2) create an image, set an AMI (in this case an HVM AMI) 3) create t2.micro compute profile (t2.micro requires HVM AMI) 4) set the image on compute profile to the image you created in step 2 5) provision a host, setting compute profile and image (on Operating System Page) AWS will report back message: InvalidParameterCombination</Code><Message>Virtualization type 'hvm' is required for instances of type 't2.micro'. Ensure that you are using an AMI with virtualization type 'hvm'. For more information, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html Which is confusing since the AMI set on the image is of type HVM. I setup a developer install of Foreman and enable compute resource API debug. The following was noted: <pre> excon.request :body => "Action=RunInstances&ImageId=ami-e0ec60d0&InstanceType=t2.micro&KeyName=foreman-1c5b55767-4b56-46a0-a8ec-955757c4f9df&MaxCount=1&MinCount=1&Placement.AvailabilityZone=us-west-2b&SecurityGroupId.1=sg-f52ffd92&SubnetId=subnet-420be726&Version=2014-10-01" :chunk_size => 1048576 :ciphers => "HIGH:!SSLv2:!aNULL:!eNULL:!3DES" :connect_timeout => 60 :debug_request => true :debug_response => true :expects => 200 :headers => { "Authorization" => "REDACTED" "Content-Type" => "application/x-www-form-urlencoded" "Host" => "ec2.us-west-2.amazonaws.com" "User-Agent" => "fog-core/1.35.0" "x-amz-date" => "20160217T205521Z" } :host => "ec2.us-west-2.amazonaws.com" :hostname => "ec2.us-west-2.amazonaws.com" :idempotent => false :instrumentor => Excon::StandardInstrumentor :instrumentor_name => "excon" :method => "POST" :middlewares => [ Excon::Middleware::ResponseParser Excon::Middleware::Expects Excon::Middleware::Idempotent Excon::Middleware::Instrumentor Excon::Middleware::Mock ] :mock => false :nonblock => true :omit_default_port => false :path => "/" :persistent => false :port => 443 :query => nil :read_timeout => 60 :response_block => #<Proc:0x0000000bba69a8@/root/foreman/vendor/ruby/gems/fog-xml-0.1.2/lib/fog/xml/sax_parser_connection.rb:29 (lambda)> :retries_remaining => 4 :retry_limit => 4 :scheme => "https" :ssl_verify_peer => true :tcp_nodelay => false :thread_safe_sockets => true :uri_parser => URI :versions => "excon/0.45.4 (x86_64-linux) ruby/2.0.0" :write_timeout => 60 excon.error :error => #<Excon::Errors::BadRequest: Expected(200) <=> Actual(400 Bad Request) excon.error.request :body => "Action=RunInstances&ImageId=ami-e0ec60d0&InstanceType=t2.micro&KeyName=foreman-1c5b55767-4b56-46a0-a8ec-955757c4f9df&MaxCount=1&MinCount=1&Placement.AvailabilityZone=us-west-2b&SecurityGroupId.1=sg-f52ffd92&SubnetId=subnet-420be726&Version=2014-10-01" :chunk_size => 1048576 :ciphers => "HIGH:!SSLv2:!aNULL:!eNULL:!3DES" :connect_timeout => 60 :debug_request => true :debug_response => true :expects => 200 :headers => { "Authorization" => "REDACTED" "Content-Length" => 250 "Content-Type" => "application/x-www-form-urlencoded" "Host" => "ec2.us-west-2.amazonaws.com" "User-Agent" => "fog-core/1.35.0" "x-amz-date" => "20160217T205521Z" } :host => "ec2.us-west-2.amazonaws.com" :hostname => "ec2.us-west-2.amazonaws.com" :idempotent => false :instrumentor => Excon::StandardInstrumentor :instrumentor_name => "excon" :method => "POST" :middlewares => [ Excon::Middleware::ResponseParser Excon::Middleware::Expects Excon::Middleware::Idempotent Excon::Middleware::Instrumentor Excon::Middleware::Mock ] :mock => false :nonblock => true :omit_default_port => false :path => "/" :persistent => false :port => 443 :query => nil :read_timeout => 60 :response_block => #<Proc:0x0000000bba69a8@/root/foreman/vendor/ruby/gems/fog-xml-0.1.2/lib/fog/xml/sax_parser_connection.rb:29 (lambda)> :retries_remaining => 4 :retry_limit => 4 :scheme => "https" :ssl_verify_peer => true :tcp_nodelay => false :thread_safe_sockets => true :uri_parser => URI :versions => "excon/0.45.4 (x86_64-linux) ruby/2.0.0" :write_timeout => 60 excon.error.response :body => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Response><Errors><Error><Code>InvalidParameterCombination</Code><Message>Virtualization type 'hvm' is required for instances of type 't2.micro'.

If you leave the compute profile blank on the host provisioning page you get :body => "Action=RunInstances&ImageId=ami-1255b321&InstanceType=t2.micro&KeyName=foreman-1c5b55767-4b56-46a0-a8ec-955757c4f9df&MaxCount=1&MinCount=1&Placement.AvailabilityZone=us-west-2b&SecurityGroupId.1=sg-f52ffd92&SubnetId=subnet-420be726&Version=2014-10-01" Where ImageId ami-1255b321 is the AMI set in the image under the Compute Resource. Maybe of note, vendor/ruby/gems/fog-aws-0.8.1/lib/fog/aws/models/compute/server.rb specifies this default AMI (ami-e0ec60d0) that is being sent.
