[libvirt] [PATCH 1/4] vmx: add VIR_DOMAIN_DEF_FEATURE_NO_BOOT_ORDER
Posted by Ján Tomko 6 years, 11 months ago
Further patches will introduce validation and a default setting
of def->os.bootDevs in postParse.

Introduce a feature flag to opt out of this and set it in the vmx
driver.

This does not clarify in any way why it is required.

Introduce a feature flag to opt out of this and set it in the vmx
driver, otherwise we would be adding it <boot dev='hd'/> into every
vmx config despite having no way to change it.

(Alternatively, if booting from hard-drive is the default, we can just
leave it in because none of the vmx code even touches bootDevs, so
it will be safely ignored)

ACK to the patch if you add this wording.

It very well might be the default. The capability can easily be deleted
later.
