<br>
Struggling with booting an instance on compute node.<br>
<br>
<br>
I am trying to boot a Scientific linux image but get "kernel panic" while booting the image. On status it shows instance "Active" and "Running".<br>
<br>
I couldn't find any logs in the compute file. one get some last lines in the VNC web console.<br>
<br>
I am using qemu with libvirtd.<br>
<br>
The strange thing is that I can boot the image with qemu commandline tool on the same host without any problem<br>
<br>
# qemu-system-x86_64 -k 'sv' cernvm-basic-2.6.0-4-1-x86.vmdk<br>
<br>
I have 3 questions.<br>
<br>
1 - Please suggest a better logging way as in compute I am not getting any error message?<br>
<br>
2 - What should I do to check what is going wrong in the system?<br>
<br>
3 - While uploading the image using "glance", I have tried following<br>
<br>
disk_formate=vmdk<br>
or<br>
disk_formate=vdi<br>
<br>
both works fine. Where<br>
<br>
container_formate=bare<br>
in both cases.<br>
<br>
Which one I should really set for the disk_formate?<br>
<br>
also there is one disk_formate vmk. What is this for?<br>
<br>
Thanks in advance.<br>
<br>
Regards..<br>
