Subject: [PATCH] detect AWS arm virtual instance as kvm
|
||
|
|
|
||
|
|
AWS arm virtual instance is KVM based hypervisor.
|
||
|
|
With this patch:
|
||
|
|
$ sudo virt-what
|
||
|
|
kvm
|
||
|
|
aws
|
||
|
|
$ cat /sys/devices/virtual/dmi/id/product_name
|
||
|
|
t4g.small
|
||
|
|
|
||
|
|
Without it:
|
||
|
|
$ sudo virt-what
|
||
|
|
aws
|
||
|
|
|
||
|
|
