That is simply not implemented.

that was fast
quick question do u think that the running kvm release is mauture enough to run around 8 vps each within 4 gb of ram heavy windows production server windows 2003 ?

depends on what you consider heavy production use.

virtualization is primary used to consolidate non-heavy used servers to one hardware.

For now, you should consider using raw disks instead of qcow2 and one cpu per VM, e1000 network card - most stable setup or win2003.

On Proxmox 2.0 you can use several data stores - gives you maximum flexibility and better performance. and before you ask when we release 2.0 - I also can´t wait but there is still some work to be done - but as soon as we got the first beta we will publish it in the forum.

HowTo use raw disk for KVM (instead of qcow2):

1. Create a new KVM VM on the web interface - remember the VMID
2. Login to the console and: cd /var/lib/vz/images/VMID
3. In this directory you will find the default disk file (vm-VMID-disk.qcow2) - just leave it
4. Create the raw disk with qemu-img (e.g. 20 GB):
   qemu-img create -f raw diskname.raw 20G
5. Go back to the web interface and remove the qcow2 disk
6. Add the newly created raw disk.
7. Check the boot order of your VM

I assume we will improve the web interface that you can do this directly (in one of the future versions)

thanks for the guide tom
but i have already installed windows 2003 how i can convert the running kvm machine to raw

and 2nd question how using the vmconverter and the guide which in proxmox wiki to migrate servers to vms
to be able to port it to raw disks

just type 'man qemu-img' to see how this works.

for the migration: just adapt the last step to create raw instead qcow2.

e.g.:

qemu-img convert -f vmdk win2003-pve.vmdk -O raw win2003-pve.raw

qemu-img convert -f qcow2 vm-300-disk.qcow2 -O raw win2003-pve.raw

what do u think?

 

[amravit]

hello tom
i wanted to keep u updated
here what i have done
1- cp vm-300-disk.qcow2 vm-300-disk.qcow2.2 to backup the file
2- qemu-img convert -f qcow2 vm-300-disk.qcow2 -O raw win2003-vm300.raw

then went through the web interface deleted the harddisk then
add new exiting one which i saw win2003-vm300.raw
started the vps

all working fine

i have also add another interface e1000 and download new drivers for it from intel which is intel pro 1000 gb interface mt for windows 2003

one strange thing that i had to remove the virtio ethernet before i be able to even see the e1000 listed in device manager
