Subject: [PATCH 08/21] aws: Detect AWS from dmidecode information.
|
|
|
ba34c6 |
|
|
|
ba34c6 |
Move the AWS detection out from under Xen. AWS runs on KVM and
|
|
|
ba34c6 |
baremetal these days. The dmidecode information for KVM and baremetal
|
|
|
ba34c6 |
is a little bit different so we also need to adjust the test for that
|
|
|
ba34c6 |
case.
