Most of our augeas files are generated during meson setup into build
directory and we were running augeas tests only for these files.
However, we have some other augeas and config files that are not
modified during meson setup and they are only in source directories.
In order to run tests for these files we need to provide different path
to both source and build directories.

EXTRA_DIST is not relevant because meson makes a git copy when creating
dist archive so everything tracked by git is part of dist tarball.
The remaining ones are not converted to meson files as they are

The virDomainGenerateMachineName() function doesn't belong in
src/conf/ really, because it has nothing to do with domain XML
parsing. It landed there because of lack of better place in the
past. But now that we have src/hypervisor/ the function should
live there. At the same time, the function name is changed to

So far, when using the qemu:///embed driver, management
applications can't chose whether they want to register their
domains in machined or not. While having that option is certainly
desired, it will require more work. What we can do meanwhile is
to generate names that include part of hash of the root
directory. This is to ensure that if two applications using
different roots but the same domain name (and ID) start the
domain no clashing name for machined is generated.

Historically threads are given a name based on the C function,

naming this name is now visible to debuggers, but also has to

The default memlock limit is 64k which is not enough to start a single
VM. The requirements for one VM are 12k, 8k for eBPF map and 4k for eBPF
program, however, it fails to create eBPF map and program with 64k limit.
By testing I figured out that the minimal limit is 80k to start a single
VM with functional eBPF and if I add 12k I can start another one.
This leads into following calculation:
80k as memlock limit worked to start a VM with eBPF which means there
is 68k of lock memory that I was not able to figure out what was using
it. So to get a number for 4096 VMs:
68 + 12 * 4096 = 49220
If we round it up we will get 64M of memory lock limit to support 4096
VMs with default map size which can hold 64 entries for devices.
This should be good enough as a sane default and users can change it if
the need to.
