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].
