qemu-kvm and libvirt: running an ancient guest
Sorry folks, I get OT again.
I already spent around 3 days now fiddling around with a new and shiny
virtualization server running am64.
I have to run a guest which is old:
Suse Linux 6.1, with a 2.2.5 kernel.
ext2-filesystems in there ...
I run that one OK on an older gentoo-host with vmware-server 2.
That box has failing hardware and I want to get rid of vmware as well
(non-working webGUI etc) ...
So far the VM boots and runs, but the performance is laggy. Seems to be
the IO somehow.
Tried raw-files on xfs, tried LVs, tried various virtual CPUs, caching
on/off, you name it ... still bad.
At first I posted to the list "email@example.com", you can read
that thread at
Then I subscribed to another list:
Still no helpful reply so far, and my customer gets angry (me too, in a
way ... 3 days, maybe one paid ... another story ...).
Does anyone of you run such old stuff within KVM?
Right now I have on the host:
gentoo-sources 3.6.1 (with all bells and whistles enabled libvirt wanted
me to enable)
(-> stable ebuilds)
When I cp a file within that VM it takes ages ... unfortunately the OS
doesn't bring much modules with it so I can't just swap the virtual
controller for SCSI or so :-(
Another old guest with a slightly newer 2.2 kernel runs just fine ... I
just don't get it.
Corrupt raw-files?? Wouldn't fsck within the guest detect that?
What to chose for 32bit-guests ... arch, cpu, etc.
I am a bit helpless ...
Thanks for any help on this.
