After a long time (2 months or so) of no updates I've updated a machine today.
As it included a kernel update I rebooted the machine.
After it came back up vde_pcapplug stopped working. I have a script that creates a switch, connect it to a physical device and then lunches some virtual machines. The script worked perfectly for a long time now.
After the update everything kept working, expect for the vde_pcapplug. I tried running the command manually, nothing happens, the log shows the following message:
kernel: device enp2s6 entered promiscuous mode
kernel: device enp2s6 left promiscuous mode
vde_switch[13591]: EOF data port: Interrupted system callWhen I try to run if with the -d flag:
vde_pcapplug[13594]: VDE_PCAPPLUG started
kernel: device enp2s6 entered promiscuous mode
kernel: device enp2s6 left promiscuous mode
vde_switch[13591]: EOF data port: Interrupted system callI've tried loading the failsafe kernel and I've tried downgrading the vde package, both didn't help.
After that I tried to open a switch and open a pcapplug to it on a different, up-to-date arch machine and encountered the same result.
I tried running it with strace (without the -d flag) but I failed to fully understand the output but as far as I did understood, this is where it crashes:
poll([{fd=3, events=POLLIN|POLLHUP}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLIN|POLLHUP}], 3, 4294967295) = 1 ([{fd=3, revents=POLLIN}])

unlink("/var/run/vde.13613-00001") = 0

exit_group(0) = ?
+++ exited with 0 +++Any one knows how can I solve that ?

I've found a temporary solution.
