I upgraded from 4.15.18-27-pve to 4.15.18-30-pve and then the virtio
driver became very unstable. This machine has run for many years on
multiple versions of Proxmox (IIRC from version 1) without any problem.

i see that my centos 5.11 VM should have support for virtio (see
below) and according to https://access.redhat.com/articles/2488201
rhel/centos supports this since 5.3.
so if virtio worked before a proxmox update, then i would call this a
regression.
can you tell which proxmox version worked for you with virtio ?
i tested centos 5.11 installer on my older pve 6.0-4 (5.0.15-1-pve
kernel) , but it does not find virtual disks.

network. There is definitly something wrong somewhere.
The only thing wrong here is that you a running a version of
RHEL/CentOS which is in maintenance support 2. This means there
will be no more updates except critical bugs. As of March 31, 2017
it is considered in deep freeze!
I know. But sometimes you need to keep an old version and a good
way to handle this is to run such an old version in a virtual
environment. A vhost supplies virtual hardware and apparently this
virtual hardware has changed. This is not A Good Thing IMHO.
It runs well under subversion 27 of the pve kernel but has stopped
under version 30. So I think this is a bug as I do not expect design
changes between subversion 27 and 30.
