Sorry folks, I get OT again. I already spent around 3 days now fiddling around with a new and shiny virtualization server running am64.
Issue: 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 "libvirt-us...@redhat.com", you can read that thread at http://www.spinics.net/linux/fedora/libvirt-users/msg03556.html Then I subscribed to another list: https://www.redhat.com/archives/virt-tools-list/2012-October/msg00068.html 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) qemu-kvm-1.1.1-r1 libvirt-0.9.13-r1 (-> 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. Stefan
