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.

Commit f107e39989 ("Switch to more traditional logging structure",
2019-06-17) replaced "logging.exception" with "log.exception", effectively
shifting the argument lists 4 characters to the left. The second and
further lines of multiline invocations were not accordingly unindented,
however, which ended up setting a suboptimal precedent as well. Unindent
those lines now.

Just to be sure, this patch implements the second approach (described in
the previous patch) as well.
Note that there is precedent for suppressing "guest_lookup" exceptions:
refer to the "Error determining machine list" branch from commit
ae7ebc220b ("details: Properly limit machine type list by guests
arch/type", 2013-09-01).
(
In fact, that branch gets activated when opening the details window for a
domain that uses a non-default emulator; the "virt-manager --debug" log
contains:
> ERROR (details:613) Error determining machine list
> Traceback (most recent call last):
> File "virtManager/details/details.py", line 605, in _init_details
> capsinfo = caps.guest_lookup(

> raise ValueError(msg)

This is a regression; according to git-bisect, it was introduced in commit
05fcc7410e ("virtinst: fix caching of domain capabilities", 2022-07-27).
"lookup_capsinfo" (and "guest_lookup" called by it) are unsuitable for
machine type alias checking (or for anything else) if the domain uses an
emulator that differs from the system default emulator. The information
returned by virConnectGetCapabilities() pertains to the system default
emulator. Thus, when using a non-default emulator, we should either not
call "lookup_capsinfo" for machine type alias checking, *or* we should
suppress the exception, and pretend that the alias check was a mismatch.
It turns out that we can avoid the "lookup_capsinfo" call (and thereby the
exception) in practice if we just delay the call until after the direct
(non-alias) comparison.

Before this, on clone the serial file would remain the same for the cloned

virt-install prints the total_size value to the progress bar even if it
is meaningless.
This value can be confusing to user, so for execute prosess that doesn't
copy files (total_size = 0B), we hide the total_size value.
For example, 'Creating domain...' doesn't need to print the total_size
value.

When a sparse file is created during a disk allocation,
virt-install prints not the created disk size but a sparse file size.
Therefore, we fix to print the created disk size during disk allocation
instead of the size of the sparse file by updating the meter with the
self.capacity.

Properly setting the metadata cache size can provide better performance
in case of using big qcow2 images.
This patch introduces two driver options:
* driver.metadata_cache.max_size
* driver.metadata_cache.max_size.unit
E.g. --disk ...,driver.type=qcow2,\
driver.metadata_cache.max_size=2,\
driver.metadata_cache.max_size.unit=MiB
BTW, Metadata cache size control is currently supported only for qcow2.
Regarding how to properly caluclate the cache size of qcow2, Please refer
to qemu's documentation.

We need to change the flow from
* parse all the strings
* set capabilities defaults
* build installer
* fill in all guest defaults
To
* parse boot and metadata strings
* set capabilities defaults
* build installer
* set --name default
* parse all the remaining strings
* fill in all guest defaults
Because --disk parsing depends on --name for some path generation.
So this fixes --disk names when --name is implicitly specified by
--install or --osinfo
