Hello,
Few months ago, I have no issue using Qemu - Virt Manager - Libvirt
Due to work, I havent use my system for 3 months. And now I am back and after updating full, I cant get it to ran or start a vm, error occured as no network
when I start the virtual network manually, I have this error
| Code: | Error starting network 'default': internal error: Failed to apply firewall command '/sbin/tc filter add dev virbr0 prio 2 protocol ip parent 1: u32 match ip dport 68 ffff action csum ip and udp': Error: Failed to load TC action module.
We have an error talking to the kernel |
details:

Hello,
I have the same issue for quite some time, however I am not able to pinpoint the missing modules you are referencing to. May you please provide more details and the link of the wiki page you are referencing to so I am able to compare more accurately, I think I might missed the exact module to fix.
~~I don’t see where your star leads to.~~ (EDIT: I noticed a bit late the `(*)` in your post is the "integrated kernel option" sign and not a link to the wiki, my bad)
Thanks in advance. |

I finally did it too!
I also set many options as "hard" about netfilter, but it didn’t work better.
However I figured out quite later to check options under “QoS and/or fair queueing”
| Code: | Location:
-> Networking support (NET [=y])
-> Networking options
-> QoS and/or fair queueing (NET_SCHED [=y]) |
I only had the “action” “Traffic Policing” as seen under this menu.
And based on the error message, I might have lack support for many other actions (kernel options such as NET_ACT_[…]), and also many “Queueing/Scheduling” (NET_SCH_[…]) and classifiers (NET_CLS_[…]).
So I enabled everything, plus the previous options, and it finally worked.
What a journey.
I might try to determine a lighter set of modifications to pinpoint the exact missing option(s), so we can try to update the ebuild so other users won’t face this issue too. |
