Subject: [PATCH 22/22] Add support for VMware ESXi on ARM
|
|
|
fcf72c |
|
|
|
fcf72c |
Virt-what doesn't recognize VMware VMs for AARCH64/ARM (with licensing
|
|
|
fcf72c |
implications in ESXi Fling for ARM and Fusion v.Next for ARM). I've
|
|
|
fcf72c |
created and attached a patch that adds both support for recognizing
|
|
|
fcf72c |
ESXi and the automated tests for it.
