Subject: [PATCH] installer: drop default TPM for --cloud-init install phase
|
|
|
|
When shim in the guest sees unpopulated EFI NVRAM, like when
|
|
we create a new UEFI VM, it invokes fallback.efi to populate
|
|
initial NVRAM boot entries. When the guest also has a TPM device,
|
|
shim will do a one time VM reset. This reset throws off the
|
|
reboot detection that is central to virt-install's install
|
|
process.
|
|
|
|
The main install case that this will usually be relevant is
|
|
the combo of UEFI and --cloud-init. The latter usually implies
|
|
use of a distro cloud image, which will be using shim, and the
|
|
--cloud-init process requires a multi stage install compared
|
|
to just a plain import install.
|
|
|
|
For that case, we disable the default TPM device for the first
|
|
boot.
