Error finding KVM instances

Submitted by Hal9000 on Fri, 05/18/2012 - 01:17

Hi there! I am running Cloudmin Pro on a server which is going to be replaced soon by another one. So I installed Cloudmin Pro on the new server and added the soon-to-die master as KVM host to it. So far so good, however it fails to find any existing KVM instance on that host. Here is the error message:

Processing KVM command /usr/bin/kvm -name mercury -m 1024 -drive file=/dev/raid/mercury_img,media=disk,index=0,if=virtio,boot=on -drive index=1,media=disk,file=/dev/ssd/mercury_ssd,if=virtio -boot c -net tap,vlan=0,script=/kvm/mercury-eth0.sh -net nic,vlan=0,macaddr=02:54:00:33:05:90,model=virtio -vnc :3,password -usbdevice tablet -monitor tcp:127.0.0.1:40000,server -smp 2 ..
.. primary disk image /dev/raid/mercury_img is not in the raw format

So it complains the disk image is not in the raw format, whatever that means. The image is an LVM volume and I created the KVM instance with Cloudmin. By the way, I also have another host which I added to the new master, and I have the same problem trying to find the instance. What can I do now?

Status: 
Closed (fixed)

What output do you get if you run :

fdisk -l /dev/raid/mercury_img

and

parted /dev/raid/mercury_img print

on the host system?

Ok, I see the cause of this now - it will be fixed in the next Cloudmin release.

The work-around till then is to add the VMs one by one, instead of doing a mass import.
