libvirt-daemon-7.5.0-1.module+el8.5.0+11664+59f87560.x86_64
qemu-kvm-6.0.0-23.module+el8.5.0+11740+35571f13.x86_64
Steps:
0. run a vm with interfaces:
# virsh dumpxml avocado-vt-vm1|grep /interface -B8
</controller>
<interface type='network'>
<mac address='52:54:00:8c:2a:67'/>
<source network='default' portid='15705c62-4e4a-48d3-a58a-e12c78ab9baa' bridge='virbr0'/>
<target dev='vnet2'/>
<model type='rtl8139'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</interface>
<interface type='direct'>
<mac address='52:54:00:44:ff:e4'/>
<source dev='enp0s25' mode='vepa'/>
<target dev='macvtap2'/>
<model type='rtl8139'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
1. Detach by right mac + wrong pci address
<interface type='network'>
<mac address='52:54:00:8c:2a:67'/>
<source network='default' portid='4512200e-a41a-45bb-b66b-a17713703ded' bridge='virbr0'/>
<target dev='vnet1'/>
<model type='rtl8139'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
# virsh detach-device avocado-vt-vm1 net4.xml
error: Failed to detach device from net4.xml
error: device not found: no device found at address '0000:00:03.0' matching MAC address '52:54:00:8c:2a:67' and alias 'net0'
2. no mac and wrong pci
# cat net8.xml
<interface type='network'>
<source network='default'/>
<model type='rtl8139'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x11' function='0x0'/>
</interface>
# virsh detach-device avocado-vt-vm1 net8.xml
error: Failed to detach device from net8.xml
error: device not found: no device found at address '0000:00:11.0' matching MAC address '(<null>)' and alias '(<null>)'
3. no PCI and wrong mac
# cat net9.xml
<interface type='network'>
<source network='default'/>
<mac address='52:54:00:76:80:66'/>
<model type='rtl8139'/>
</interface>
# virsh detach-device avocado-vt-vm1 net9.xml
error: Failed to detach device from net9.xml
error: device not found: no device found at address '(<null>)' matching MAC address '52:54:00:76:80:66' and alias '(<null>)'
4.multiple interface with the same mac
Change the second interface of vm to also use mac 52:54:00:8c:2a:67',
<interface type='network'>
<mac address='52:54:00:8c:2a:67'/>
<source network='isolated' bridge='virbr2'/>
</interface>
# virsh detach-device avocado-vt-vm1 net11.xml
error: Failed to detach device from net11.xml
error: operation failed: multiple devices matching MAC address 52:54:00:8c:2a:67 found
5. no matching device found
Run vm without interface device.
# virsh dumpxml avocado-vt-vm1|grep interface
(nothing)
# cat net6.xml
<interface type='network'>
<source network='default' bridge='virbr0'/>
</interface>
# virsh detach-device avocado-vt-vm1 net6.xml
error: Failed to detach device from net6.xml
error: device not found: no device found at address '(<null>)' matching MAC address '(<null>)' and alias '(<null>)'
