The commit message needs some massaging.
Essentially, this patch fixes the "condition" where if a guest has been
started and someone uses attach-device with (or without) the --config
option, then these checks will avoid the "next" guest being modified,
correct?
This will also cause an error earlier that patch 1/2 as
qemuDomainChrInsert is called in the path before qemuDomainAttachDeviceLive

Typically in switches listing other options rather than default:

Same, but:
case VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_NONE:
case VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_LAST:

Same, but:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_XEN:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_UML:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_LXC:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_OPENVZ:
case VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_LAST:
I think perhaps this one is better than 1/2, but will see if my
responses result in other opinions...
