Sorry folks, I get OT again. |

I already spent around 3 days now fiddling around with a new and shiny |
4 |
virtualization server running am64. |
5 |
|
6 |
Issue: |
7 |
|
8 |
I have to run a guest which is old: |
9 |
|
10 |
Suse Linux 6.1, with a 2.2.5 kernel. |
11 |
ext2-filesystems in there ... |
12 |
|
13 |
I run that one OK on an older gentoo-host with vmware-server 2. |
14 |
|
15 |
That box has failing hardware and I want to get rid of vmware as well |
16 |
(non-working webGUI etc) ... |
17 |
|
18 |
So far the VM boots and runs, but the performance is laggy. Seems to be |
19 |
the IO somehow. |
20 |
|
21 |
Tried raw-files on xfs, tried LVs, tried various virtual CPUs, caching |
22 |
on/off, you name it ... still bad. |

At first I posted to the list "libvirt-users@××××××.com", you can read |
27 |
that thread at |

|

http://www.spinics.net/linux/fedora/libvirt-users/msg03556.html |

|

Then I subscribed to another list: |

Still no helpful reply so far, and my customer gets angry (me too, in a |
36 |
way ... 3 days, maybe one paid ... another story ...). |

Does anyone of you run such old stuff within KVM? |
39 |

|
42 |
Right now I have on the host: |
43 |
|
44 |
gentoo-sources 3.6.1 (with all bells and whistles enabled libvirt wanted |
45 |
me to enable) |
46 |
|
47 |
qemu-kvm-1.1.1-r1 |
48 |
libvirt-0.9.13-r1 |
49 |
|
50 |
(-> stable ebuilds) |

When I cp a file within that VM it takes ages ... unfortunately the OS |
55 |
doesn't bring much modules with it so I can't just swap the virtual |
56 |
controller for SCSI or so :-( |
57 |
|
58 |
Another old guest with a slightly newer 2.2 kernel runs just fine ... I |
59 |
just don't get it. |
60 |
|
61 |
Corrupt raw-files?? Wouldn't fsck within the guest detect that? |
62 |
|
63 |
What to chose for 32bit-guests ... arch, cpu, etc. |
64 |

I am a bit helpless ... |

Thanks for any help on this. |
