When a (raw) guest image is placed on an ext4 filesystem,
it is possible to get data corruption, now due to ext4
bug, not kvm bug.
Also, ext4 is _very_ slow on O_SYNC writes (which is
used in kvm with default cache).
JFYI.

Hi guys,
I have the following configuration:
1. host is RHEL 5.5, 64bit with KVM (version that comes out of the box
with RHEL 5.5)
2. two guests:
2a: RHEL 5.5, 32bit,
2b: RHEL 4.5, 64bit
If I run iperf between host RHEL 5.5 and guest RHEL 5.5 inside the
virtual network subnet I get great results

Thank you a lot for the tip - you were right. The 5.5 guest is using
virtio, but 4.5 is not. So, this is the reason.
Adding to the config file unfortunately
doesn't help - the network card is not recognized by the guest. Do I
need to install something extra on the guest RHEL 4.5?
