Unable to connect to libvirt qemu + ssh

Help libvirt doesn’t start anymore since the 157 core update. What can i do, help. Unfortunately, my English is not that good.

When I try to connect QEMU / KVM with a double click, I get the following error message:
Unable to connect to libvirt qemu + ssh: //libvirt-remote@192.168.1.1: 222 / system.

End of file while reading data:: input / output error

Verify that the ‘libvirtd’ daemon is running on the remote host.

Libvirt URI is: qemu + ssh: //libvirt-remote@192.168.1.1: 222 / system

Traceback (most recent call last):
File “/usr/share/virt-manager/virtManager/connection.py”, line 1012, in _do_open

if ret is None: raise libvirtError (‘virConnectOpenAuth () failed’)
libvirt.libvirtError: End of file while reading data:: input / output error

Now I have read in ‘wiki.ipfire.org - Libvirt’ that it is important to note: Note - Support for macvtap has been dropped as of Core Update 156. Please use bridges instead. It still worked under core 156. Have under Set up zones Green stand on bridge. But unfortunately I can’t get any further, help …

This not looks like a macvtab problem. Try if ssh is working. virtviewer meed a working ssh on the IPFire to reach libvirt.

These are mine ssh Settings at Ipfire
I have no idea to handle this problem.

in the ipfire konsole:

can I restore the state before the core deterioration 157 and how

7

is ssh working without virtmanager. This must work first.

8

an ssh connection from the client to the ipfire works, the console input is attached.

client_pc $ ssh -p 222 root@192.168.1.1

or what exactly is meant by that first ssh connection, give me an example that I can enter into the console

9

this is correct.

10

I have to confirm this as bug. ncat is crashing with Segfault and prevent the connetion via virtmanager.

If there a question, yes ssh connection to ipfire works.
