Hi all. We found some interesting thing, that container freeze for 1.2 sec then network activity from corosync started (unicast udp 5404->5405 between cluster members) and unfreeze after them ended (and rtp traffic burst detected). Any help would be appreciated.

Many thanks for answer. No, we use migration only for move container to different hardware (in off state) for tests. 'Freeze' problem persists on all nodes (on lab, on production). After analyze tcpdumps we seen very strange network problems inside hosts (tcpdump on external interface of host...

Hi all! "A long time ago" we try to migrate our small office PBX (Asterisk 11 + CentOS6) to Proxmox (LXC container) and discovered problem with voice that called standstill (one way audio). We have up to 7 concurent SIP calls (maximum 1 Mbps of voice traffic). Only one container running on...

Alwin, engin - Many thanks for answers and for point me to right direction (udevadm test). Problem was not in kernel, problem was in udevd configuration (that applied by systemd). Someone (package or user - i will investigate) create /etc/systemd/network/more 99-default.link: [Link]...

Alwin - many thanks, i will read docs about changes in udev (and systemd) and reload-rules after that. engin - you are right , content of /etc/default/grub here: and no options net.ifnames=0 biosdevname=0 is defined on both nodes. and no significant changes in /boot/config... : # diff...

Thanks for answer. BIOS was not updated for more than 1 year and udev rules was not edited by hand. On node with new kernel: # udevadm info /sys/class/net/eth0 P: /devices/pci0000:00/0000:00:07.0/0000:03:00.0/net/eth0 E: DEVPATH=/devices/pci0000:00/0000:00:07.0/0000:03:00.0/net/eth0 E...

Hi guys ! I had a 2 node cluster with 4.13.13-6-pve (4.13.13-41) and 4.13.13-5-pve (4.13.13-36). Hardware is - HP DL360G7 with Broadcom NetXtreme II 4 ports integrated network card. After upgrade one node from 4.13.13-36 to 4.13.13-41 all ethernet interfaces names changed from enp3s0f0 to eth0...
