Re: [libvirt] [PATCHv3 2/3] domain_conf: Add helpers to verify if device configuration is valid

This patch adds helpers that validate domain's device configuration. This will be needed later on to verify devices being hot-plugged to guests. If the guest has no USB bus, then it's not valid to plug a USB device to that guest. --- Diff to v2: - split out USB device checking to a separate function - made virDomainDefHasUSB static as it's not used outside of domain_conf.c --- src/conf/domain_conf.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 3 ++ src/libvirt_private.syms | 1 + 3 files changed, 56 insertions(+), 0 deletions(-)
