> Interesting. Have others seen this problem? 

In the thread I mention at the head of this thread - '[Xen-devel] Failure to 
create HVM DomU at Xen 4.1 ( kernel 3.0.0-5-generic) Ubuntu 11.10 (alpha 2)' - 
I summarize several threads from people that have had problems starting hvm 
domu's on xen 4.1.x. They all have similar log output to mine, namely:

qemu-dm:

xen be: console-0: xen be: console-0: initialise() failed

& hypervisor.log (xm dmesg) reports an MMIO error. The fix was either to 
upgrade to xen 4.2 unstable, or downgrade to 4.0.x - at least until Konrad 
proposed adding the vfb= line, in that same thread in Xen-users. This made  
4.1.x usable, and made the MMIO error go away (but not the 'xen be:' error). 
Thus, there is only one other person I know benefited from that advice -        
bderzhavets. However, I'll repeat the list of other threads in Xen-users of 
people with hvm problems:

> According to several threads, such as mine last month - '[Xen-users]

> '[Xen-users] Re: Trouble starting HVM domU with Linux 3.0.0 and Xen 4.1.1',

and one I omitted, from the beginning of July: '[Xen-users] Starting basic HVM 
-- where am I going wrong?' from Sam Mulvey.

> I don't think vfb-line is supposed to be needed with HVM guests..

It hasn't been needed since xen 3.2.x (maybe even 3.0.x) until 4.1.x, and 
again reportedly not needed for 4.2 unstable ( I haven't worked with it, yet).

Thank you for continuing to take an interest in this.
