RE: [Xen-users] Debian 6 as Dom0 not booting on Xen 4.1.1

[Antonio Colin <dftonywhite@xxxxxxxxxxx>]

Hello guys,

Sorry for the delay too, but I wanted to post until I had good news :). And actually I do. I have managed to compile vanilla kernel 3.1.0 rc8

from Linus Torvalds' site: https://github.com/torvalds/linux I am working on Debian 6 with kernel 2.6.32-5. But I decided to compile it since

I need Dom0 and ROOT NFS support as well.

@JPPO: Thank you! I cannot use the debian kernel packages because I need to customize the kernel to have ROOT NFS working. It's

worth saying I tried it but it didn't boot since it stopped at: [ configuring network interfaces... ] (never continuing)

Now It boots perfectly, but it is far too much slow, it has taken 3 hours now and it cannot finish starting GDM, it shows the little white circle

spinning but nothing more yet.

I have also added dom0_mem=1024 to the linux kernel module. Any ideas guys?

Thank you a lot!

Regards,

Tony.

Hi,
 
Sorry for the delay in replying.
 
So the kernel that works is 3.0.0 ?
 
I am using 3.0.4 and it works very well, solved some of my other issues.
 
Thanks
 
Ian

Hello,
 
If you are using Debian 6 you could try the vmlinuz-3.0.0-1-rt-amd64 kernel which seems to work very well on my system.
I think it is worth a try.
 
Regards
 
JPPO
