Upstream status: not applicable
|
||||
|
||||
Currently we use the host physical address size by default on
|
||||
VMs. This was a good default on most cases, but this is not the
|
||||
case on host CPUs supporting 5-level EPT. On those cases, we
|
||||
want VMs to use 4-level EPT by default.
|
||||
|
||||
Ensure VMs will use 4-level EPT by default, by limiting physical
|
||||
address bits to 48.
|
||||
|
||||
Not applicable upstream because upstream doesn't set
|
||||
host-phys-bits=on by default.

Subject: redhat: Post rebase synchronization
|

We based rebase on qemu-kvm-3.1.0-23.el8. However, 8.0.1 version moved
|
||||
to qemu-kvm-3.1.0-25.el8. Adding missing changes.

Merged-patches (4.0.0):
|

- ebb6e97 redhat: Fix LOCALVERSION creation
|

- b0ab0cc redhat: enable tpmdev passthrough (not disabling tests)
