Hi,
I found my VM libvirt create xml as:
<hostdev managed="no" mode="subsystem" rawio="yes" type="scsi"> <source> <adapter name="scsi_host0"/> <address bus="2" target="4" unit="0"/> </source> </hostdev>
I found https://libvirt.org/formatdomain.html#elementsHostDevSubsys like blow:
... <devices> <hostdev mode='subsystem' type='scsi' sgio='filtered' rawio='yes'> <source> <adapter name='scsi_host0'/> <address bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </hostdev> </devices> ...
Is <address> mandatory?
No, it is not mandatory. If not set, it would be determined by libvirt. See [1].
