For KVM i'm not certain, for VMware - you can pass arbitrary vmware specific configs via API, assume one can pass boot order - but havent yet tried..

France,

I am not sure changing the boot sequence can be changed. In KVM installations 
if an ISO is attached then it will be booted automatically, I assume it's the 
same with Xenserver.

Just for the future reference, how can I change the boot order to boot from CD
first?

I shut down one of the working instances and attached the iso for centos 6.4
minimal to it. Started the instance again and it did boot form disk as
expected. I also did not see an option to boot from cd on console.

Tnx and regards,
F.

Subject: Access root disk after botched upgrade
Hi,

after upgrading Ubuntu Linux, the system does not boot, probably because of
wrong grub config format:
(           errorInfo: [Traceback (most recent call last):,   File
"/usr/bin/pygrub", line 808, in ?,     fs = fsimage.open(file, part_offs[0],
bootfsoptions), IndexError: list index out of range, ])

How can I get access to disk of this VM, to fix the grub file by hand and try to
restart it?
I have CS 4.3 on XS 6.0.2 with ISCSI disk for virtual instances.

Tnx.
France.
