Error can’t add wlp5s0 to bridge br0: Operation not supported
Help me what do i do next…

i have only one ethernet interface (ens2), could i make my machine as virtual host (for learning purpose)? i lost internet connection after i established bridge between br0 and ens2 with command “sudo brctl addif br0 ens2”. if there must be two interfaces, the blog chould make it clear in hardware requirement.

And another typo
$ sudo gpasswd -a USER libvirt

Hi. There is a small error in the text above .
$ sudo addif br0 eth0
MoSes
Im using KVM/QEMU with vmm aswell since my host is a Ubuntu 16.04.
Nonetheless im not quite sure about the big differences in comparision with virtualbox. Could you name a few?

Under “Manual Bridged Networking”, “sudo addif br0 eth0” should be “sudo brctl addif br0 eth0”.

Why don’t you use virt-manager to configure the bridge as well? Does it work better with network-manager?

I am not a VM expert for KVM, but can I import existing VMs, made, for example, with Virtual BOX or VMware ? If I can run my VMs with less bloatware and just the essential software, that would be great. I’m a newvie for KVM, although I use VMs under VMware for over 8 years…

You can use disk images from VirtualBox and VMware. You can also convert the disk images to qcow2. The virtual hardware is different though, so you need to reconfigure your guest OSs a bit sometimes. I’ve migrated from all sorts of VMs to KVM/QEMU without issues.
