#Network issues after installing QEMU/KVM

After installing QEMU/KVM my wired network connection keeps disconnecting or going into a limited connectivity state. It happens on both wired interfaces. I've had Arch installed for about a week now and never had a single issue until I installed QEMU/KVM. I've tried to -Rns QEMU but I still have issues. My wireless connection works fine, but I'd rather use wired.

That sounds odd, how long does it stay disconnected for?

If it happens for a decent amount of time, u should compare "ip addr" commands to see what's going on with your net interfaces

#

huh, alright

#

if you do "journalctl -b" and page down through the results does anything show up?

#

it just happened again and thats the last entry

agile hound
#

So i can see that the dispatcher service is just continuously running and it's bringing your interface down

#

well it's not bringing it down, but ur losing connection

dreamy prism
#

I just stopped libvirtd service. I think it might be tied to it.

agile hound
#

yea there's a good chance of that

dreamy prism
#

Now its acting normal.

agile hound
#

That's good.

#

U could try tweaking the virtual network setting in libvirtd, that could help

#

U could also enable debug logging for NetworkManager to get clearer picture of what's going on

#

Gotta figure out how to do that. It's been years since I used Linux.

agile hound
#

oh it's in that link

dreamy prism
#

I'm ashamed because I'm Linux+ certified LOL

#

But that was back in 2009-2010

agile hound
#

lol all good, I'm CCNA certified and i'm still embarased by a lot of this stuff

dreamy prism
#

I haven't been in IT for years tho. I drive a semi

agile hound
#

I'm just trying to get my first support gig

dreamy prism
#

Well, you can use me as a reference.

agile hound
#

lol I may have to with the luck I've been getting

#

In that article though, the guy ended up disabling connectivity checking, which seemed to have fixed the issue for them

left cargo
#

Is this fixed?
