[PATCH v3 0/5] qemu: Support rbd namespace attribute
Diff from v2:
- rebase to master
- update some qemu capabilities tests
Test results of this patch series on qemu-5.0.0 and librbd1-14.2.8:
disk xml:
<disk type='network' device='disk'>
<driver name='qemu' type='raw'/>
<auth username='admin'>
<secret type='ceph' usage='ceph_example'/>
</auth>
<source protocol='rbd' name='rbd/1' namespace='hhan'>
<host name='CEPH_MON'/>
</source>
<target dev='vde' bus='virtio'/>
</disk>
Live attach and detach the disk:
➜ ~ virsh attach-device new /tmp/ceph-ns.xml
Device attached successfully
➜ ~ virsh dumpxml new|xmllint --xpath //disk -
<disk type="file" device="disk">
<driver name="qemu" type="qcow2"/>
<source file="/var/lib/libvirt/images/new.qcow2"
index="2"/>
<backingStore/>
<target dev="vda" bus="virtio"/>
<serial>WD-WMAP9A966149</serial>
<alias name="virtio-disk0"/>
<address type="pci" domain="0x0000" bus="0x02"
slot="0x00" function="0x0"/>
</disk><disk type="network" device="disk">
<driver name="qemu" type="raw"/>
<auth username="admin">
<secret type="ceph" usage="ceph_example"/>
</auth>
<source protocol="rbd" name="rbd/1"
namespace="hhan" index="3">
<host name="CEPH_MON"/>
</source>
<target dev="vde" bus="virtio"/>
<alias name="virtio-disk4"/>
<address type="pci" domain="0x0000" bus="0x03"
slot="0x00" function="0x0"/>
</disk>
➜ ~ virsh detach-device new /tmp/ceph-ns.xml
Device detached successfully
➜ ~ virsh dumpxml new|xmllint --xpath //disk -
<disk type="file" device="disk">
<driver name="qemu" type="qcow2"/>
<source file="/var/lib/libvirt/images/new.qcow2"
index="2"/>
<backingStore/>
<target dev="vda" bus="virtio"/>
<serial>WD-WMAP9A966149</serial>
<alias name="virtio-disk0"/>
<address type="pci" domain="0x0000" bus="0x02"
slot="0x00" function="0x0"/>
</disk>
It also works when start VM with this disk.
And tests pass when it is tested with -blockdev disabled:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='blockdev'/>
<qemu:add capability='drive'/>
</qemu:capabilities>
</domain>
