Xen Support

I have searched the forums for a definitive answer to this and have not found one. Currently running Xen 4.x on SLES 11 sp2. What I am trying to find out is if astaro is supported running on this platform. I have tried the following.

I have tried with both 8.3.x installer and 9.x.

1. Install as a HVM using any type of network adapter whether full or para
virtualized will hang the installer at finding network adapters. It hard locks.

2. Attempt to install as paravirtualized os just hangs upon booting the cd. I am using the iso to install from saying it is not a supported boot device or something like that.

I have tried as sles 11 and also as other for the type of virtual machine.

Thank you for any advice.

Any specific reasons you want to have paravirtual support?

For paravirtual support, remove lines kernel, builder and boot. Then add the following lines:
bootloader = "/usr/lib/xen/boot/domUloader.py"
bootargs="--entry=xvda1:/boot/vmlinuz,/boot/initrd"
extra="root=/dev/disk/by-label/root rootflags=data=ordered"

To access the console, you have to edit /etc/inittab within the virtual UTM
and replace "tty1" by "hvc0".

Hello,since domUloader.py is a SUSE specific way, and I use Debian, Ihad to use pygrub instead...

But I have independently on the fact which loader is specified following error if trying to start the domain:


Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found\n')

and in the xend.log I can see following:

I donot know,if the problem cannot be caused by the fact, I just use the hvm installed domain,which takes the given LVM drive and uses it like a disk, not like a partition - there are all Astaro partitions on it...
No Idea how to configure the instance and pygrub to use such data scheme...
Is there any way how to install Astaro on concrete partitions without automatically partitioning the disk?
