What were you trying to do that didn't work?
Failed to update interface portgroup dynamically
What is the impact of this issue to you?
Please provide the package NVR for which the bug is seen:
libvirt-10.8.0-2.el9.x86_64
qemu-kvm-9.1.0-1.el9.x86_64
How reproducible is this bug?:
100%
Steps to reproduce
- Define and start a network with two portgroups
#cat net.xml <network> <name>net2</name> <uuid>e1c51804-bd55-49e8-8814-e21a2c7f9af6</uuid> <forward mode='nat'/> <bridge name='virbr1' stp='on' delay='0'/> <mac address='52:54:00:db:19:75'/> <ip address='192.168.100.1'> <dhcp> <range start='192.168.100.100' end='192.168.100.254'/> </dhcp> </ip> <portgroup name='sales' default='yes'> <bandwidth> <inbound average='100' peak='200' burst='512'/> <outbound average='50' peak='100' burst='256'/> </bandwidth> </portgroup> <portgroup name='engineering'> <bandwidth> <inbound average='200' peak='300' burst='256'/> <outbound average='100' peak='200' burst='128'/> </bandwidth> </portgroup> </network> #virsh net-define net.xml Network net2 defined from net2.xml #virsh net-start linux_br_OA9 Network net2 started
2.Start guest with the network:
#virsh edit vm2 ... <interface type='network'> <mac address='52:54:00:4a:70:f1'/> <source network='net2'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x09' slot='0x00' function='0x0'/> </interface> ... #virsh start vm2
3.check the bandwidth settings in the live xml is the same as "sales" since it is the default portgroup:
<interface type="network"> <mac address="52:54:00:4a:70:f1"/> <source network="net2" portid="4666e307-a0b2-4200-8329-24bbd624a6ad" bridge="virbr1"/> <bandwidth> <inbound average="100" peak="200" burst="512"/> <outbound average="50" peak="100" burst="256"/> </bandwidth> <target dev="vnet7"/> <model type="virtio"/> <alias name="net1"/> <address type="pci" domain="0x0000" bus="0x09" slot="0x00" function="0x0"/> </interface>
4.Prepare a interface device with net2 network and engineering portgroup:
#cat if.xml <interface type="network"> <mac address="52:54:00:4a:70:f1"/> <source network="net2" portgroup="engineering"/> <model type="virtio" /> <address type="pci" domain="0x0000" bus="0x09" slot="0x00" function="0x0" /> </interface>
5.Update the interface portgroup to be as 'engineering':
# virsh update-device vm2 if.xml error: Failed to update device from if.xml error: Operation not supported: cannot modify network device portgroup attribute
Expected results
Should update interface portgroup dynamically successfully.
Actual results
Failed to update interface portgroup dynamically
