about the new added attributes "check" and "type" for interface mac element
Hi all, I have done some tests for the new attributes "check" and "type", could you please help to have a check? And I have some questions about the patch, please help to have a look, Thank you! The questions: 1. in step 4 below, the error message should be updated: Actual results: XML error: invalid mac address **check** value: 'next'. Valid values are "generated" and "static". expected results: XML error: invalid mac address **type** value: 'next'. Valid values are "generated" and "static". 2. I have checked the vmware OUI definition and found this: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.... it says the VMware OUI is 00:50:56, not 00:0c:29 in the patches. Am I missing something? 3. Could you please tell more about the user story? as I can not understand the scenario when " it will ignore all the checks libvirt does about the origin of the MAC address(whether or not it's in a VMWare OUI) and forward the original one to the ESX server telling it not to check it either". Does it happen when we try to transform a kvm guest to a vmware guest? 4. How to test it as a libvirt QE? Are the test scenarios below enough without ESX env? Test steps: 1. Start vm with different configuration with mac in "00:0c:29" range: # virsh dumpxml rhel | grep /interface -B12 ... <interface type='network'> <mac address='00:0c:29:e7:9b:cb' type='generated' check='yes'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:3b:e0:50' type='static' check='no'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0d' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:73:f6:dc' type='generated' check='no'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0e' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:aa:dc:6c' type='static' check='yes'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0f' slot='0x00' function='0x0'/> </interface> # virsh start rhel Domain rhel started 2. login guest and check the interfaces: # ip addr ... 2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:e7:9b:cb brd ff:ff:ff:ff:ff:ff inet 192.168.122.142/24 brd 192.168.122.255 scope global dynamic noprefixroute enp5s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::351c:686a:863e:4a7f/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: enp11s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:3b:e0:50 brd ff:ff:ff:ff:ff:ff inet 192.168.122.202/24 brd 192.168.122.255 scope global dynamic noprefixroute enp11s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::2b79:4675:6c59:6822/64 scope link noprefixroute valid_lft forever preferred_lft forever 4: enp12s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:73:f6:dc brd ff:ff:ff:ff:ff:ff inet 192.168.122.33/24 brd 192.168.122.255 scope global dynamic noprefixroute enp12s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::e43d:555:ba85:4030/64 scope link noprefixroute valid_lft forever preferred_lft forever 5: enp13s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:aa:dc:6c brd ff:ff:ff:ff:ff:ff inet 192.168.122.161/24 brd 192.168.122.255 scope global dynamic noprefixroute enp13s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::f32d:e2e8:9c8b:47fd/64 scope link noprefixroute valid_lft forever preferred_lft forever 3. start vm without the "check" and "type" attributes, and check the live xml do not include these attributes, either. # virsh start vm1 virshDomain vm1 started # virsh dumpxml vm1 | grep /interface -B8 </controller> <interface type='network'> <mac address='52:54:00:bb:cd:89'/> <source network='default' portid='b02dc78f-69ad-4db7-870c-f371fd730537' bridge='virbr0'/> <target dev='vnet22'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </interface> 4. negative test: Set "<mac address='52:54:00:bb:cd:89' type='next'/>" in virsh edit # virsh edit vm1 error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domain.rng Extra element devices in interleave Element domain failed to validate content Failed.

Hi, I have filed a bug about the error messages, https://bugzilla.redhat.com/show_bug.cgi?id=1892130 And I will track the questions on that bug, please help to update on the bug comments about the questions. Thank you! ------- Best Regards, Yalan Zhang IRC: yalzhang On Wed, Oct 21, 2020 at 10:51 AM Yalan Zhang <yalzhang@redhat.com> wrote:

4. How to test it as a libvirt QE? Are the test scenarios below enough without ESX env?
Test steps:
1. Start vm with different configuration with mac in "00:0c:29" range: # virsh dumpxml rhel | grep /interface -B12 ... <interface type='network'> <mac address='00:0c:29:e7:9b:cb' type='generated' check='yes'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:3b:e0:50' type='static' check='no'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0d' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:73:f6:dc' type='generated' check='no'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0e' slot='0x00' function='0x0'/> </interface> <interface type='network'> <mac address='00:0c:29:aa:dc:6c' type='static' check='yes'/> <source network='default'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x0f' slot='0x00' function='0x0'/> </interface>
# virsh start rhel Domain rhel started
2. login guest and check the interfaces: # ip addr ... 2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:e7:9b:cb brd ff:ff:ff:ff:ff:ff inet 192.168.122.142/24 brd 192.168.122.255 scope global dynamic noprefixroute enp5s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::351c:686a:863e:4a7f/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: enp11s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:3b:e0:50 brd ff:ff:ff:ff:ff:ff inet 192.168.122.202/24 brd 192.168.122.255 scope global dynamic noprefixroute enp11s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::2b79:4675:6c59:6822/64 scope link noprefixroute valid_lft forever preferred_lft forever 4: enp12s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:73:f6:dc brd ff:ff:ff:ff:ff:ff inet 192.168.122.33/24 brd 192.168.122.255 scope global dynamic noprefixroute enp12s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::e43d:555:ba85:4030/64 scope link noprefixroute valid_lft forever preferred_lft forever 5: enp13s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:aa:dc:6c brd ff:ff:ff:ff:ff:ff inet 192.168.122.161/24 brd 192.168.122.255 scope global dynamic noprefixroute enp13s0 valid_lft 3584sec preferred_lft 3584sec inet6 fe80::f32d:e2e8:9c8b:47fd/64 scope link noprefixroute valid_lft forever preferred_lft forever
3. start vm without the "check" and "type" attributes, and check the live xml do not include these attributes, either. # virsh start vm1 virshDomain vm1 started # virsh dumpxml vm1 | grep /interface -B8 </controller> <interface type='network'> <mac address='52:54:00:bb:cd:89'/> <source network='default' portid='b02dc78f-69ad-4db7-870c-f371fd730537' bridge='virbr0'/> <target dev='vnet22'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </interface>
4. negative test: Set "<mac address='52:54:00:bb:cd:89' type='next'/>" in virsh edit # virsh edit vm1 error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domain.rng Extra element devices in interleave Element domain failed to validate content
