Virtualizing RedHat 6.1

Virtualizing RedHat 6.1

[Davide Bologna]

I am installing this old rh release to virtualize some Oracle8i database i need to consolidate and mantain until 2011.

The guest installation goes fine, no problem at all. But network is not functional. The guest configure eth0 correctly, all drivers are in place, routing table is correct, but the guest cannot communicate with any other device on the network.

I tried both user network and bridge/tap networking, neither works. I am sure my network configuration is correct, i have tested it with other guests that works fine, even xp, so i suspect this problem depends from ye old rh, maybe some network kernel option; still not analyzed this.

The host is Debian testing (kvm-72).

Does someone on the list as already tried this ? The more I try, less clues I get.

Regards

Davide

Try changing the guest network driver (there are two rtl8139 drivers 
IIRC) or switching to ne2000.

Just for you information: oracle8i works fine on current linux (we use debian 5.0).
Even on 64bit platform 32bit oracle works, but for that you need a little wrapper
to tell linux to use old 3Gb user/kernel memory split (I can show you more details
if you want).

That all to say: there's no need to run Oracle8i on old (and buggy) system, current
linux works.

Upgrade to 0.10.5.  You can use my packages (http://www.corpit.ru/debian/tls/kvm) if
you want.

But better just run real system, without any virt stuff.

I am glad if you can point me to instruction for installing it on Lenny.
Maybe better off-list as is not kvm related.
Thank you.

I don't have instructions per se.  I don't even remember how I installed it in
the first place.  At least installer required some option to omit host OS check,
it's in the `runInstaller -help' output somewhere, and there was something about
gcc version (it needs gcc-3.4 at max if memory serves me right, or even 2.95).
Also first 8i release does not work, it fails at relink stage, which can safely
be ignored and done later when 8.1.7.4 patchset is installed.

But once installed (you may even do it on real rh-6.x) you can just copy it to
another machine (together with a few user/group definitions and a few files in
/etc) or upgrade your current one.  That's basically what I always did.

What I tried to say really is -- if you want to run it on 64bit system you need
a special program I wrote to set up linux personality properly.  While 64bit
kernel is able to run 32bit executables just fine, oracle8i is buggy and assumes
3g/1g memory split, while on 64bit kernel it's more like 4g/0g (it gives almost
all 4g memory to userspace), and oracle crashes at startup.  But only on 64bit
system and without ADDR_LIMIT_3GB personality flag.

Sure it's not kvm-related, but you're not first to have this idea.  There are 8i
installs still (8i is not supported anymore by Oracle).  Lacking better place,
let's make it archived and findable here... ;)

So it should work on Debian i386, I think I'll give it a try
