Thanks for reporting the bug.

Does the workaround from the doc text of bug 1478865 helps in your scenario?

Hi Dominik,

Thank you for the link, but the workaround from bug1478865 is not acceptable.

Based on the RedHat support answer (https://access.redhat.com/solutions/2435891), it is not safe to use old network device naming.
Red Hat strongly recommends that the new RHEL7 and RHEL8 naming conventions are used.

I think that customers could get unexpected behavior for oVirt hosts in the further oVirt updates if predictable Network Interface feature will be disabled.
Moreover, this functionality on oVirt 4.3.9 is working properly. This suggests that there was a mistake in the code during update oVirt 4.4.

Hi Pavel,

what about the second proposed workaround. Adding udev rules for the interfaces that are causing the troubles? 

Something like:

ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:50:56:8e:12:34", NAME="eth123"

Should do the trick. 

Is this possible workaround until we have proper solution in place?

Hi Ales,

The second proposed workaround will not wrk too.
I can rename parent interface name with udev rule (link it via MAC address). For example i can rename enp175s0f0 to the enp175s0
But virtual interface, that will be created from this parent interface, still will have default name enp175s0f0v0.

At the same time, i can't rename virtual interface name because I can't prognoses MAC address that will be provided to the virtual interface.

Hi Pavel,

Since the PCI address is stable for SR-IOV PF and thus VFs have also predictable PCI addresses that are inherited from PF.
It depends on the driver but you should be able to find the pattern of PCI assignment to VFs and then you can use rule like this:

ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:03:00.0", NAME:="eth123"

Hopefully this helps.

> oVirt Team, can you please help to solve this issue. It urgent for me, because I can't upgrade my ovirt environment from 4.3.9 to the 4.4
> oVirt 4.3.9 don't have this issue, therefore it is functionality degradation.

Was the interface naming in 4.3.9 different for you?

Hi Dominik

Checked oVirt 4.3.9
Yes, oVirt 4.3.9 does not have v0/v1 prefixes at the end of virtual interface names.
Also, eno virtual interfaces do not have v0/v1 and some eno virtual interfaces do not have f0v0/f0v1 prefixes.

My oVirt 4.3.9 has next interfaces. This is for example.
Physical interfaces:
 - eno1
 - eno2
 - eno3
 - eno4
 - enp59s0f0
 - enp59s0f0
 - enp175s0f0
 - enp175s0f1

Virtual interfaces:
 - enp24s10    (parent: eno3)
 - enp24s10f1  (parent: eno3)
 - enp24s14    (parent: eno4)
 - enp24s14f1  (parent: eno4)
 - enp175s16f1 (parent: enp175s0f1)

Hi Ales,

I have tested udev rule with linking physical network interfaces to the PCI slots.

Added this configuration:
# cat /etc/udev/rules.d/60-persistent-net.rules
ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:00.0", NAME:="enp175s0"
ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:00.1", NAME:="enp175s1"

After reboot got correct network names:
# ip a | grep enp175s
6: enp175s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
7: enp175s1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

But when I enabled VFs for interface enp175s0 from oVirt "Setup Host Network" I got the new virtual interface with long name: enp175s0f0v0


Unfortunately, this workaround don't work

Hi Pavel, 

there has been slight misunderstanding. The rules that you did handle only the physical function (PF). 
If you enable VFs via sysctl/webadmin the VF itself gets assigned different PCI address. For example
if your PF has PCI address 0000:af:00.0 the VFs can get something like 0000:af:01.0, 0000:af:02.0, 0000:af:03.0 etc.
The assignment pattern depends on your network card driver but should be deterministic. You can find this by
looking at lspci -D with some of the VFs enabled. 

For the names that you have mentioned as reply to Dominik, we comply with the rules that set by systemd. 
That being said there is probably some change between el7 and el8 in systemd which caused this. 
The change that seems to fit to what you have described was done in systemd version v239 [0][1].







[0] "v239

    Naming was changed for virtual network interfaces created with SR-IOV and NPAR and for devices where the PCI network controller device does not have a slot number associated.
    SR-IOV virtual devices are named based on the name of the parent interface, with a suffix of "vport", where port is the virtual device number. Previously those virtual devices were named as if completely independent.
    The ninth and later NPAR virtual devices are named following the scheme used for the first eight NPAR partitions. Previously those devices were not renamed and the kernel default ("ethN") was used.
    Names are also generated for PCI devices where the PCI network controller device does not have an associated slot number itself, but one of its parents does. Previously those devices were not renamed and the kernel default was used."

Hi Ales,

Thank you for clarification.
I finally managed to apply your's workaround partially. But this workaround is accompanied by a lot of nuances and problems. And can't be fully used due to random error during assign Logical Networks to the network interfaces.


First of all, I want to describe steps, that allow me to get virtual interface with less name length:
1. First of all, need to get PCI address of virtual interfaces, that I will have. To get PCI addresses, I've activated virtual functions. As result, was configured next udev rules:
    # cat /etc/udev/rules.d/60-persistent-net.rules
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:00.0", NAME:="enp175s0"
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:00.1", NAME:="enp175s1"
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:10.0", NAME:="enp175s0v0" #virtual interface, parent: enp175s0
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:10.2", NAME:="enp175s0v1" #virtual interface, parent: enp175s0
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:10.1", NAME:="enp175s1v0" #virtual interface, parent: enp175s1
    ACTION=="add", SUBSYSTEM=="net", KERNELS=="0000:af:10.3", NAME:="enp175s1v1" #virtual interface, parent: enp175s1

2. Then, was renamed ifcfg file names and inner device names from enp175s0f0 to enp175s0, and from enp175s0f1 to enp175s1:
    # mv /etc/sysconfig/network-scripts/ifcfg-enp175s0f0 /etc/sysconfig/network-scripts/ifcfg-enp175s0
    # mv /etc/sysconfig/network-scripts/ifcfg-enp175s0f1 /etc/sysconfig/network-scripts/ifcfg-enp175s1

3. As result, will be changed interfaces. We remember that for a configured oVirt host in the cluster, this will cause issues. Therefore, I have removed record about old interfaces:
    # mv /var/lib/vdsm/persistence/netconf/devices/enp175s0f0 /var/lib/vdsm/persistence/netconf/devices/enp175s0
    # mv /var/lib/vdsm/persistence/netconf/devices/enp175s0f1 /var/lib/vdsm/persistence/netconf/devices/enp175s1
    # mv /var/lib/vdsm/staging/netconf.6qiaKssQ/devices/enp175s0f0 /var/lib/vdsm/staging//netconf.6qiaKssQ/devices/enp175s0
    # mv /var/lib/vdsm/staging/netconf.6qiaKssQ/devices/enp175s0f1 /var/lib/vdsm/staging//netconf.6qiaKssQ/devices/enp175s1

Removed infromation about interfaces enp175s0f0 and enp175s0f1 from file /var/lib/lldpad/lldpad.conf

Disabled virtual interfaces:
    # echo 0 > /sys/class/net/enp175s0f0/device/sriov_numvfs
    # echo 0 > /sys/class/net/enp175s0f1/device/sriov_numvfs

Removed information about old iSCSI sessions:
    # rm -rf /var/lib/iscsi/nodes/*

By the way, if you know a simpler and more correct way to change the network interfaces for a configured oVirt host, please tell about it, I did not find mention of this in the oVirt documentation.

4. Reboot oVirt Host.

5. After reboot checking that interfaces renamed correctly:
    # ip a | grep enp175
    5: enp175s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    6: enp175s1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

6. After reboot and successfull activation oVirt host on the oVirt Engine, enable VFs (virtual functions) for new interfaces: enp175s0, enp175s1.
As result we will have virtual interfaces like these:
    # ip a | grep enp175
    5: enp175s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    6: enp175s1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    62: enp175s0v0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    63: enp175s0v1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    64: enp175s1v0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    65: enp175s1v1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000


All this time maintenance for oVirt Host was not activated. This allow VDSM sync the new networks with oVirt Engine databace.


7. After that I tried to assign Logical Network with Vlan id 811 to the virtual interface enp175s1v1. But got again error ""Error while executing action HostSetupNetworks: Unexpected exception"."
In the log files i found next.

My oVirt Logical Network has MTU 9000, but virtual interface - MTU 1500
I've changed MTU size for physical network interface enp175s1 from 1500 to 9000, disabled virtual functions. Then enabled virtual functions again.
After that, I can assign Logicall Network to my virtual interface.

8. Finally, need reboot oVirt Host to ensure that no issue with interfaces and host activation works.


As a result, was found two issues here:
1. oVirt can't handle cases where interface name + vlan id length size greater than 15 chars
2. oVirt can't assign Logical Network with MTU size 9000 to the virtual interface if physical network configuration has MTU size 1500. Seems, this is oVirt software bug, because NetworkManager able to prepare ifcfg config with required MTU.



Ales, Dominik, as you see it is too difficult to manually activate virtual functions for network cards.
As an oVirt user, I must say that such oVirt’s behavior when working with VFs - akin to a nightmare in the production environment.
It would be just great if the oVirt team could fix this problem.
I hope, that I provided all the required information, that will help to fix the bug.

Hi Pavel,

I am investigating what can be done to avoid this in future. Would you please be willing to give some more info from your machine?

For further investigation I will need output from following. 

1) udevadm info /sys/class/net/enp175s0
2) cat /usr/lib/systemd/network/99-default.link

My though are that your machine uses naming called "path". In general this naming results in longer names because it includes the PCI path of device [0].
On the other hand naming called "slot" should shorten device names as it includes just PCI slot [0]. 

The default systemd config should be as follow:

NamePolicy=kernel database onboard slot path


Thanks, 
Ales
