I've successfully set up the bridging; a CentOS 7 VM on the same host
has full connectivity. So it's something about the rtl8139 and the
2.0.36 kernel. What is the oldest distribution you've done on KVM on C7?
Ok, so I've progressed somewhat on this. Here's what I've so far found:
1.) RHL 5.2 installs fine, but is a no-go, since it has no networking.
2.) RHL 6.2 installs fine, but is a no-go, with lots and lots of 'hda:
lost interrupt' errors and eventually the guest is paused and won't
proceed past a certain point in the boot. Of all the days for the
Fedora infrastructure to go completely down, while I'm looking for
archived RHL (!!!). For a while I couldn't even get to archive.org.
Trying to get to bugzilla.redhat.com was impossible, and even archived
mailing list posts were not available talking about the lost interrupt
issue (google's cache will only help you so far). It was a pretty odd
sight, seeing a 'www.redhat.com is down but will be back soon' webpage
come up.
3.) vault.centos.org to the rescue; CentOS 2.1 is essentially an RHL
7.x-derived distribution, and so I grabbed the two ISOs from a vault
mirror. The GUI install crashes out completely, but a text install
worked swimmingly. Since the app I need does have a glibc2.1 version,
and since I already had it downloaded from back in 1998 or so, using the
RHL 6.2 compat-glibc2.1 packages should work. Installed, booted, and got
networking. The C2.1 guest seems stable, and I'm pulling the updates
repo from vault.centos.org and will set up local repos for yum (yum
version 1!) and get it as fully updated as C2.1 can be (this isn't
exposed to the internet). Once updated and the compat-glibc2.1
installed will try out the app in a testing mode, then pull over the
database (postgresql 6.5, but I have a good dump I can restore into the
C2.1 postgresql) and bring it back live.
Now, there is one other option that I found this morning: the LinuxTech
repo for CentOS 6 has a libc5 for CentOS 6. I'm setting up a testing C6
i386 guest, and will try out the LinuxTech libc5. If that works that
will be the route I go, since C6 is still updated. I'm not going to
abandon the C2.1 setup yet, though, since the app I'm using may need
some other libs. We'll see.
So, to answer my own question, CentOS 2.1 is the oldest thing I have
thus far successfully run with full server functionality in C7's
qemu-kvm-ev.
