accel/kvm: check for KVM_CAP_READONLY_MEM on VM
|
|
|
|
KVM_CAP_READONLY_MEM used to be a global capability, but with the
|
|
introduction of AMD SEV-SNP confidential VMs, this extension is not
|
|
always available on all VM types [1,2].
|
|
|
|
Query the extension on the VM level instead of on the KVM level.
