I noticed the same thing on pm-5.4 when upgrading from 4.15.18-27-pve
to 4.15.18-30-pve. Suddenly on (old) Debian Lenny guests the virtio
drivers got very unstable. I changed them to rtl8139 and it seems to be
much stabler, but not resolved. I created a cronjob that stops the
network, unloads the kernel modules, reloads them and restarts the
network. There is definitly something wrong somewhere.
