Hello,
I have CentOS 6.3 installed on a server with dual Xeon CPU's.
Motherboard info:
http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRT-HF.cfm
CPU info (we have two of these):
Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz
I've also heard that older versions of Windows don't put the CPU to
idle mode even when there is nothing to do. It is a known problem with
older Windows kernels.
Anyway, try to install the latest virtio drivers for Windows if you
don't already have.

It's not related to your problem. Just a note: when you use the noatime
mounting option in fstab then you do not need to use nodiratime because
noatime takes care of both.

Try to use qemu-img directly, like this:
qemu-img convert -f vmdk -O raw Your-Original-Disk-Image.vmdk

I'm not an expert on this, but here is what I would try:
1. Are you using the latest virtio drivers on your Windows guest(s)?
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/
2. Is there any particular reason you use CentOS 6.4 on your storage server?
I would update it to
I experienced similar issues when disk images of virtual machines were
stored in qcow/qcow2 files instead of logical volumes (LVM).
Using LVM gives you way better I/O performace than using qcow files.
Also very important: when you partition your disk drive(s) make sure
that partitions are
For KVM virtual machines, I always use virtio type NICs. That is for
performance.
I never had any problems under CentOS 6.4 and 6.5.

When I converted the disk image to a raw logical volume (created with

You need to add eth0 to the bridge (br0) which you already did. But do
NOT assign an IP address to eth0. Instead, assign the host's IP to br0.
Then just use another of your IPs for your VM (which can also be called
eth0 inside your VM).
This way your host and your VM(s) can communicate with each

Why don't you SSH into the running guest from the host and change the

If sshd is not running on your guest then you can try to stop (shutdown)
the guest and use libguestfs to modify files inside the VM's disk.

Do you have only one public IP address and do you want to share that
between your host and your VM(s)? In this case you must use NAT config.
If you have multiple public IPs and you want to assign one of those to
your host and another of those to your guest (VM) then you must create a

Steve,
Try the following config.
On your host:

ONBOOT=yes

HWADDR=xx:xx:xx:xx:xx:xx- put your physical NIC's MAC address here

Looking at the specs for the processor it does not seem to have the
vmx features in /proc/cpuinfo:
http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.35100.0.html
and the output from grep -E ‘vmx|svm’ /proc/cpuinfo is empty.
Hello,
IMO, it's better to check for this on
network entries:
function='0x0'/>

I would stop the VM, edit its definition file (that's an XML file) and then
start it up. But be careful: After you edit the XML file, you need to
execute a command so KVM re-reads that file. I forgot that command, but you
can look it up on Google.

Are the disk partitions properly aligned to 4k boundary on the host (and
in the guests too) ?

I did many physical (Windows) to virtual (kvm) conversions before. The

you must add a dummy ("fake") 2nd disk drive to the guest first, boot up
