Recently installed Proxmox VE 6.3. Two guests work OK, two have > 50 % packet loss so not really useful.
I can not understand what is wrong with the two problem hosts. Both of them I moved today from Proxmox 5.4-15, dumped and restored on this newer proxmox. Of the two working hosts one I created as KVM guest, the other was transferred from that older proxmox two days ago. Guess are Debian 9, 10 or Devuan 2.2.
Attached ping.txt shows packet loss, ping every 1 seconds. For about 10 seconds it works, then for about 20 seconds it does not work and this repeats.
ping2.txt shows pinging another VM on same subnet works, packet loss is 0%.
How to fix this so all the guests also access hosts outside the local subnet?

I have already tried:
- deleted the network device and added it back to force MAC change
- changed network device from VirtIO to Intel E1000
- compared settings between the working guests and not working guests
