[PATCH 01/15] qemu: introducing qemu_validate.c/h
Daniel Henrique Barboza
danielhb413 at gmail.com
Thu Mar 26 21:31:11 UTC 2020
While moving validations from qemu_command to qemu_domain,
it was suggested that we should instead move them to a new
file [1] because qemu_domain is already too crowded.
This patch introduces a new file to host such validations from
the QEMU driver. And to get things started, let's move
qemuDomainDefValidateFeatures() to this new file.
