Hello,
I use one ip3 with xen and qubes-os.
bios: 0.25.08, qubes-os4, fedora29, no NetworkManager.
I have a bad behavior, after reboot, randomly, i can't ping others computer with rj45 ethernet (no wifi using)
No issues with fedora configuration as iptable, route and...
I reboot several times and the connection can raise up without conf modification. I never lose the ethernet connection until one reboot.
No error message in logs about e1000e / igb intel module, pci or other think linked to ethernet use.
Somebody would have one idea of this issue?
Thanks.
Alain

As much as we'd like to help, we lack the knowledge to advise regarding Xen or cubes OS.
In order to troubleshoot this issue, we suggest to test it in a supported environment such as Windows or Linux mint which are known to work.
For Linux installation please follow the guide below:

For Windows, please follow the below:

Please see if you are able to replicate the same behavior on these environments.
