I've got a CentOS 7 server KVM with 2 virtual machines running on it. I've been using virt-manager remotely for a couple of weeks without problems… Until yesterday when it froze and I could not connect to the server anymore.
I get the following error message:
Cannot connect to libvirt
packet 458961001 bytes received from server too large, want 16777216
ibvirt URI is: qemu+ssh://root@[IP]/system
Traceback (most recent call last):

libvirtError: packet 458961001 bytes received from server too large, want 16777216
Virtual Manager connection is qemu+ssh://root@[IP]/system
I don't know why this started to happen. I tried restarting the libvirtd daemon, the VMs and the server itself but the error is still there. I've also tried from another client PC but nothing…
I googled it but I couldn't find a solution 🙁
What am I doing wrong?

I finally found why this happened! It was my fault, because I added some code to execute when starting an ssh connection in
.bashrc
file, and that was the large answer received by virt-manager.
