I noticed -cpu help printing enough trailing spaces to make the output
at least 84 characters wide. Looks ugly unless the terminal is wider.
Ugly or not, trailing spaces are stupid.
The culprit is this line in x86_cpu_list_entry():
qemu_printf("x86 %-20s %-58s\n", name, desc);
This prints a string with minimum field left-justified right before a
newline. Change it to
qemu_printf("x86 %-20s %s\n", name, desc);
which avoids the trailing spaces and is simpler to boot.
A search for the pattern with "git-grep -E '%-[0-9]+s\\n'" found a few
more instances. Change them similarly.

The hashes of each of the files is calculated (or the string in the case
of the cmdline with trailing '\0' included). Each entry in the hashes
table is GUID identified and since they're passed through the

By default, KVM allows the guest to use all currently supported PV features
even when they were not announced in guest visible CPUIDs. Introduce a new
"kvm-pv-enforce-cpuid" flag to limit the supported feature set to the
exposed features. The feature is supported by Linux >= 5.10 and is not
enabled by default in QEMU.

In sev_read_file_base64() we call g_file_get_contents(), which
allocates memory for the file contents. We then base64-decode the
contents (which allocates another buffer for the decoded data), but
forgot to free the memory for the original file data.
Use g_autofree to ensure that the file data is freed.
